728 LYMPHATIC SYSTEM OF THE OX AND SHEEP 
pericardium, the peritoneum; the liver; the ribs, costal cartilages, and sternum; 
the ventral mediastinal glands. The efferent vessels usually concur in forming 
one or two trunks which run forward along the internal thoracic vessels to the 
anterior gland. From the latter one or two efferents go to the anterior mediastinal 
glands or directly to the end of the right tracheal duct or the thoracic duct (on the 
left side). 
The axillary lymph gland lies on the medial face of the distal part of the teres 
major on the course of the vein from the latissimus dorsi. It is oval in outline and 
is usually a little more than an inch (ca. 3 em.) in length. Quite exceptionally two 
glands may be present. The efferent vessels come from most of the muscles of the 
shoulder and arm, the muscles of the forearm, the trapezius, latissimus dorsi, pee- 
toralis profundus, and cutaneus; the fascia of the forearm; the shoulder, elbow, and 
sarpal jomts; the scapula, humerus, radius, ulna, and carpus; the infraspimatus 
gland. The efferent vessels (one to three) go to the posterior cervical glands. 
The infraspinatus lymph gland (Lg. infraspinata) is a small node which is present in 
somewhat less than a fourth of the cases (Baum). It is situated at or near the posterior border of 
the infraspinatus, about on a level with the proximal end of the caput longum. It receives lymph 
vessels from the latissimus dorsi and sends an efferent vessel to the axillary gland. 
The rhomboid lymph gland (Lg. rhomboidea) is small and only present in about 15 per 
cent. of subjects (Baum). It is situated under the rhomboideus cervicalis near its ventral border 
and the cervical angle of the scapula. It receives afferents from the rhomboideus, supras- 
pinatus, and serratus ventralis, and sends efferents to the costocervical gland. 
The lumbar lymph glands (Leg. lumbales) are situated along the abdominal 
aorta and the posterior vena cava, and in some of the spaces between the transverse 
processes. Some of the glands are dorsal to the vessels. Haemolymph glands also 
occur in this region. The afferent vessels come from the spimal, sublumbar, ab- 
dominal. and serratus dorsalis muscles; the lumbo-dorsal fascia; the kidneys, 
adrenals, and the peritoneum; the lumbar vertebre. The efferent vessels go to 
the lumbar trunk and the cisterna chyli. 
The renal lymph glands (Lee. renales) belong in reality to the preceding group, 
from which they are only conventionally distinguished. They are situated on the 
course of the renal vessels and vary in size and number. Their afferent vessels come 
from the kidneys and adrenals, and the efferent vessels go mainly to the cisterna 
chyh. 
The coeliac lymph glands (Lge. cceliacee), two to five in number, are situated on 
and near the ceeliac and anterior mesenteric arteries, and in relation to the left 
extremity of the pancreas, the dorsal curvature of the rumen, and the posterior 
vena cava. One is a large discoid gland which lies on the cceliae artery and the 
origin of the chief branches of that vessel (Fig. 389). It is heart-shaped, marked 
by a deep notch, and is about two inches (ca. 5-6 em.) long and an inch and a half 
(ca. 3-4 cm.) wide. Their afferent vessels come from the spleen. The efferent 
vessels go to the common efferent vessel of the gastric lymph glands, or to the 
intestinal trunk, or to the cisterna chyli. 
The internal iliac lymph glands are situated in relation to the terminal branches 
of the aorta and the radicles of the posterior vena cava. They number commonly 
six to eight and vary in length from half an inch to two inches (ca. 1-5 em.). Their 
afferent vessels come chiefly from muscles of the sublumbar region, pelvis, tail, and 
thigh; from the genital organs; from the kidneys, bladder, and urethra. They also 
receive vessels which are efferents of the external iliac, sacral, ischiatic, deep in- 
guinal, prefemoral, and coxal glands. Their efferent vessels go chiefly to the lumbar 
trunk. 
1 Baum distinguishes those about the vessels as Igg. lumbales aorticse, and terms those in 
the intertransverse spaces lgg. lambales proprie, and regards them as corresponding to the dorsal 
mediastinal and intercostal glands respectively.
