Fig. 525. — Diagrammatic Representation of the Muscles of the Trunk and of the 
Distribution of the Segmental Nerves by which they are supplied, shown in a 
Thoracic Segment. 

NOTE. 

A brief explanation of this diagram seems needful, in the interest of students who have not made a special study of comparative 
anatomy. The muscles are grouped, first of all, into dorsal and ventral, the former being supplied by the posterior and the latter by the 
anterior primary divisions, respectively, of the spinal nerves. The dorsal muscles form the great mass lying chiefly in the hollow between 
the spinous processes and the angles of the ribs. They are classed in two group.s — superficial and deep. These need not be further 
considered. The ventral muscles are shown to be arranged in three layers. In the abdominal region these are represented by three 
actual muscles, to name them from within outwards : the transversalis, the internal oblique, and the external oblique. Continuous with the 
deepest of these, the transversalis, for the purposes of this classification, are the triangularis sterni, the subcostals, the sternal and costal 
portions of the diaphragm and part of the levator ani— these form the siihcostal layer. Continuous with the internal oblique are the intcr- 
costals, the posterior serrati, the scalene muscles, and the quadratus lumborum — these form the intercostal layer. Continuous with the 
e.vternal oblique are all the muscles connecting the scapula with the trunk, viz.: the trapezius, levator anguli scapulae, serratus magnus, 
and rhomboidei muscles, also the iatissimus dorsi, the pectorals, the sternocleidomastoid, and the superficial perineal muscles— these 
constitute what may he called the appendic»Iar\a.yi^T. There is finally a more superficial layer still (not shown in the figure), superficial 
indeed to the deep fascia, corresponding to the panniculosus carnosus of lower mammals, but represented in man only by the platysma 
myoides, the occipitofrontalis, and the muscles of the ear and face. — Tr.

' Concerning these bursse Quain writes (" Elements of Anatomy." loth ed., vol. ii., Part II., p. 221): " In 
many cases there is a small bursa above the olecranon, either between the tendon of the triceps and the 
posterior ligament, or more frequently in the deep part of the tendon itself. A bursa behind the internal 
condyle, beneath the inner edge of the triceps and the ulnar nerve, is of rare occurrence." — Tr. 

- The epitroclileo-ancoiieus is a small muscle often found, which arises from the posterior surface of the interna! 
condyle of the humerus, and is inserted into the olecranon. It is superficial to the ulnar nerve. When 
absent, it is represented by a band of transverse fibres in the deep fascia of the arm. — Tr.

AND THE BURS^ OF THIS ReGION. 

Ill order to display the intratendinous and the subtendinous burSEC of the olecranon, tno longitudinal 
incisions have been made in the distal extremity of the triceps e.xtensor cubiti muscle, and the 
posterior margins of the incisions have been retracted witli hooks. In the region of the forearm 
the deep fascia has been left intact.

= The author adheres to the cld nomenclature of the short muscles of the thumb, but that introduced by Cunningham is now generally 
adopted by English anatomists. Following this writer, the former adductor pollicis is called the adductor pollicis trans7'Crsrts, and what 
used to be called the deep head of the jflcxor brevis pollicis muscle is divided into two parts. The larger part, known as the Oiiductor 
oblitfiitis pollicis, the largest of the thumb muscles, consists of several slips arising from the upper ends of the second and third metacarpal 
bones, the os magnum, the anterior carpal Hsaments, and the sheath of the tiexor carpi radialis muscle ; the muscle is inserted, in common 
with the adductor transversiis and the deep head of the flexor brevis, into the inner side of the base of the lirst phalanx of the thumb. 
What is now termed th-j decf> head of i^ttjlcxor brevis pollicis is a very small slip, deeply placed between the adductor obliqiius pollicis 
and the outer head of the abductor indicis. It arises from the ulnar side of the upper part of the first metacarpal bone, and is inserted as 
already described. — Tr. See also Figs. 573, 585, and 586.

I have given the preference to the old names, as more distinctive and therefore more suitable, of the three extensor muscles of the 
thumb, e.rtcnsorossis tnvtacarfii pollicis, extensor prhyii intemodii pollicis^ and extensor secundi interyiodii pollicis. Quani (•' Anatomy," 
loth ed.) has, however, adopted the Continental nomenclature in the case of the two latter muscles, which he terms respectively extensor 
brevis pollicis and extensor longus pollicis, whilst yet other names have been adopted by Macali^ter, who terms the extensor of the first 
\>\\3\m\x, extensor pollicis minor, :ind the extensor of the second phalanx extensor pollicis major. The names used in the text are, however, 
more faniiliar to students, both in England and America, and there seems no good reason for any change. 

While speaking of these muscles, it may be mentioned that their tendons, viz., those of the extensor ossis metacarpi pollicis and extensor 
primi intemodii pollicis on the radial side, and that of the extensor secundi intemodii pollicis on the ulnar side, bound the deep hollow to be 
seen on the outer (radial) side of the wrist and behind the metacarpal bone of the thumb, when this member is fully extended. This hollow is 
known as the tabatii're anatomique, or anatomical sntiff-lox (called by Toldt /oz'cola radialis, see Fig. 575). Beneath the tendons of 
the extensors of the thumb, and across the intervening hollow, the radial artery pa-sses from the front to the back of the wrist, its direction 
being indicated by a line from the front of the styloid process of the radius to the proximal end of the first interosseous space ; and the 
arterj- is ci^ossed by the superficial radial vein, which usually forms a distinct prominence in the hollow between the tendcns. — Tr. 

3 liy English anatomists the supinator and extensor muscles are, like those of the front of the forearm, divided simply into two layers : a 
superficial, containing seven muscles, viz., the supinator radii longus, extensor carpi radialis longior, extensor carpi radialis brevior, extensor 
comnmnis digiloriiin, extensor miuimi digiti, extensor carpi ulnaris, and anconeus muscles ; and a deep layer, containing five muscles, viz., 
the supinator radii brevis, extensor ossis metacarpi pollicis. extensor primi intemodii pollicis, extensor secundi intemodii pollicis, and 
extensor indicis muscles. The author's classification of these muscles is to be found in the description at the foot of Figs. 574, 575, and 
576.— Tk.

note ' on same page) and the subjacent tendons of insertion of the gracilis and semitendinosus muscles. .\ prolongation of the bursa 
passes more deeply between these latter tendons and the subjacent^ internal lateral ligament of the knee-joint. — Tn. 

^ The bursa of the inner /lead 0/ the gastrocneiniits jnuscle is situate between the inner head of origin of the gastrocnemius muscle 
and the tendon of the semimembranosus muscle. This bursa frequently communicates with the knee-joint. Higher up, between the 
tendon of the inner head of the gastrocnemius muscle and the femur, there is usually a second, smaller synovial bursa, which may also 
communicate with the knee-joint. — Tr. 

3 The bursa 0/ the sentimentbratwsits muscle is situate between the tendon of insertion of the semimembranosus muscle and the 
prominent upper margin of the groove on the internal tuberosity of the tibia into which the semimembranosus muscle is mainly 
inserted. — Tk.

Fig. 617.— Superficial Group^ of the Posterior Musclks of the Right Leg, First Portion: Gastrocnemius 
Muscle, constituting the Two Superficial Heads of the ^Triceps Sur.^ Muscle.^ 

Of the deep fascia of the leg. the lower portion of the superficial layer, which binds down the tendo Achillis, and the deep 
layer, which passes from side to side between the superficial and the deep posterior muscles of liie leg, have been 
retained. The plantaris muscle and its tendon are partially visible. 

J The author divides the posterior muscles of the leg into three groups or lavers, the 6rst. most superficial, consisting of the gastroc- 
nemius muscle ; the second consisting of the plantaris and soleus muscles ; and the third, deepest, consisting of the popliteus, flexor longus 
hatlncis, flexor longus digitorum pedis (or flexor perforans), and tibialis pt>sticus muscles. This arrancement appears a ver>' artificial one, 
and I have therefore adhered to the arrangement usually adopted by English anatomists, according to which the muscles are grouped in 
two layers only : a superficial, consisting of the gastrocnemius, soleus, and plantaris muscles ; and a deep, consisting of the muscles already 
enumerated as making up the author's third layer. — Tr.

3 Like the author, English anatomists group the muscles of the sole in four laj'ers, but the two classifications are not i^ntirely identical. 
That of the author is given in the description at the foot of Figs. 625 to 628. ^ According to English anatomists, thejirst or superficial layer 
consists of the flexor brevis digitorum (or flexor perforatus), abductor hallucis and abductor minimidigiti muscles ; the .Jtri>7/</ layer consists 
of the tendons of the flexor longus digitorum (or flexor perforans) and flexor longus hallucis muscles, together with the flexor accessorius 
and lumbricales muscles; the ////></ layer consists of the flexor brevis hallucis, adductor obliquus hallucis, adductor transversus hallucis, 
and flexor brevis minimi digiti muscles ; and the foitrth layer consists of the dorsal and plantar interosseous muscles, together with the 
tendons of the tibialis posticus and peroneus longus muscles. — Tr.

2 The susf'ensory ligament of the penis consists of two parts : a sufierfcia ', the fa^se supeitsory'h'^ament ; and a deefi, the tr:u 
suspensory ligament, "The former, called by the author ligamentiDu funk forme penis, when artificially separated from the fascia of the 
abdomen and the dorsum of the penis (of which it forms a part), is a flattened piece of connective tissue with edges directed laterally and 
surfaces directed forwards and backwards, respectively. The latter, called by the author iigamenium sitspensorium penis, when dissected 
out, has an anterior free edge, a postero-superior edge attached to the front of the pubic symphysis, and a postero-inferior edge attached 
to the dorsum of the penis, whilst its surfaces look to right and to left (see Fig. 632). The false suspensory ligament contains many yellow 
elastic fibres ; the true corfrists of while fibres only. — Tk.

' Anomalous OMuraior Artery. — The normal origin of the obturator artery is from the internal iliac artery, and it sendsan anastomotic 
branch to the deep epigastric artery ; but quite frequently this anastomotic branch becomes the main trunk, so that the obturator artery- 
arises, as here, from the external iliac in common with the deep epigastric. When the anomalous obturator artery takes the course shown 
in the figure, directly downwards across the internal iliac vein to reach the obturator canal, the anomaly is of little practical importance ; 
but in some cases (once in fifty-eight bodies, and more often in males than females) the anomalous obturator artery courses first inwards, 
and then arches backwards on the inner side of the femoral ring, so that it is in danger of being cut when dividing the stricture in cases of 
strangulated femoral hernia. — Tk.

» Fascia Iliopeclinea. — The author distinguishes by this name that portion of the iliac fascia (of English anatnniists) which, covering 
the iliopsoas muscle as it passes beneath Poupart's ligament, forms the septum between the iliac cotnf'aytmeni and the z'ascular compart- 
ment of the space beneath that ligament, and passing inwards behind the femoral vessels to form the posterior layerof the femoral or crural 
sheath becomes continuous with the pul'ic portion of the fascia lata of the thigh, ox pectineal fascia (see description at foot of Fig. 508), 
]). 349. From the fact that this portion serves to connect the iliac with the pectineal fascia arises the name " iliopectineal fa.scia."— Tk. 

3 Pubic Li^^amcnt ofAstley Cooper^ or Cooper •< /,i^an}ent.— This name is gi\ en to a thickened bundle of transverse fibres at the upper

and in part derived from, Gimbernat's ligament. — Tr.
