14.5 spinal nerves

network of nerves derived from last three or four cervical and first one or two thoracic nerves (depending on species); supplies front limbs

nerves that supply hind limbs, extending below level of spinal cord, deriving their name from arrangement of their strands, whih resemble a horse's tail; terminal part of spinal cord, meninges and nerves

key nerve of hind limb; innervates major extensor muscles of stifle; loss of innervation results in inability to bear weight on hind limb

network of nerves derived from last few lumbar and first one, two or three sacral nerves; supplies hind limbs

sensory and motor nerve that supplies muscles of thigh and skin of hip, thigh and knee joint; paralysis of nerve can occur with parturition, especially in cows

sensory and motor nerve that originates in sciatic nerve and supplies muscles of lower hind limb and skin of foot and toes

sensory and motor nerve that supplies diaphragm, lung, pericardium, and peritoneum

sensory and motor nerve that supplies skin, erectile tissue and muscle of perineal area

sensory and motor nerve of brachial plexus that innervates forelimb; provides innervation to major extensors fo elbow joint; loss of innervation results in inability to bear weight on forelimb

sensory and motor nerve, largest in body; supplies main extensor muscles of hip and flexor muscle of stifle; paralysis results in profoudly abnormal gain and posture

supplies muscles of shoulder; paralysis causes atrophy of supraspinatus muscle (called sweeny in horses)
