“…Similar to the descriptions in most domestic animals [8,9,13,21], the lateral thoracic nerve in the chacma baboon received components from C-8 to T-2. The nerve was joined by cutaneous branches from the first two or three intercostal nerves and gave rise to the intercostobrachial nerve which supplied the skin and cutaneous muscles near the caudal aspect of the scapula.…”

“…In the chacma baboon, the formation of three trunks, viz., a cranial (superior) trunk by C-5 and C-6, a middle trunk by C-7 alone, and a caudal (inferior) trunk by C-8, T-1, and T-2, was similar to trunk formation in vervet monkeys [3], humans [24], and in most non-human primates except in the gorilla where only two trunks are formed [15]. Trunk formation was not commonly reported in domestic animals due to great species variation [8,9,13,21]. However, three trunks have been described in the dog [l] and two trunks have been described in the Japanese wild goat [2].…”

“…The brachial plexus is considered the major route for all the nerves to the forelimb. In order to understand its anatomical complexities and to make phylogenetic comparisons, the brachial plexus has been studied in a variety of mammals [13,15], including humans [24]. Investigations in the vervet monkey [3] confirmed comparative findings that the I Accepted June 6,1997. brachial plexus is structurally related to the functional abilities of the forelimb in the species studied.…”

The brachial plexus in each of ten embalmed, mature chacma baboons was dissected to document the structure and branching pattern of this nerve plexus in this increasingly used research animal. In general, the brachial plexus in the chacma baboon was similar to the plexuses in the vervet and other Old World monkeys. However, several aspects were comparable to those observed in domestic animals. Thus the bipedal and quadrupedal abilities of the chacma baboon were reflected in the structure of its brachial plexus.

Background Saguinus leucopus is a Neotropical primate with an arboreal quadrupedal locomotion pattern, which requires wide movements of the shoulder and arm. This investigation studies the muscles of these regions in order to serve as a basis for clinical and surgical procedures and to compare with other primates. Methods Gross dissections of twenty thoracic limbs were performed. Results The muscles examined were the deltoid, supraspinatus, infraspinatus, subscapularis, teres major, teres minor, coracobrachialis longus, coracobrachialis brevis, biceps brachii, brachialis, triceps brachii, tensor fasciae antebrachii, and anconeus epitrochlearis. The anconeus was absent. The following variants were found: an accessory head of the biceps brachii, the unilateral absence of the short head of the biceps brachii, an accessory head of the coracobrachialis longus, and one infraspinatus muscle innervated by the axillary nerve. Conclusions These muscles are adapted to quadrupedal locomotion and can have inter‐ and intraspecific variations in their attachments and innervation.

This study provides detailed description of the gross morphology and distribution of the nerves arising from the cervical segments of the spinal cord of the African Giant Rat (AGR). Two (2) AGRs were used for this study. The rats were euthanized using halothane. The skin and superficial fascia were removed, and dissection of the muscles in the cervical region and thoracic limbs was carried out. The vertebral canal was opened by means of a rongeur. Eight (8) pairs of spinal nerves (C1–C8) arose from the cervical segments of the spinal cord of the AGR by means of dorsal and ventral roots which merged lateral to the spinal cord to form spinal nerves. Each cervical spinal nerve divided into a dorsal and ventral ramus just before exiting the intervertebral foramen. The dorsal rami divided into medial and lateral branches distributed on the medial faces of the semispinalis and splenius muscles, respectively. The ventral rami of C1, C2 and a branch from C3 interconnected to form the cervical plexus from which branches were distributed to the M. cleidomstoideus, M. cleidooccipitalis, M. occipitoscapularis, M. omotransversarius and M. trapezius. The ventral rami of C5, C6, C7, C8 and T1 (first thoracic spinal nerve) interconnected to form the brachial plexus. The cervical spinal nerves gave rise to dorsal rami or primary branches that supplied the skin and muscles of the dorsal part of the neck and the ventral primary branches which interconnected to give rise to the cervical plexus and brachial plexuses of the AGR.
