31. The nerves that innervate teres major consist of fibers from spinal nerves C8. 32. A single afferent nerve fibre branches to innervate up to 90 such endings. 33. The subscapular nerves are innervated by the posterior division of the brachial plexus. 34. Later, thalamic axons invade layer 4 where they innervate layer 4 neurons. 35. The glossopharyngeal nerve innervates a third of the tongue including the circumvallate papillae. 36. The caudal serotonergic nuclei heavily innervate the spinal cord, medulla and cerebellum. 37. This excitatory interneuron innervates the alpha motor neuron that controls the antagonist muscle. 38. Splanchnic nerves of the sympathetic nervous system innervate the medulla of the adrenal gland. 39. The right vagus branch innervates the sinoatrial node. 40. The median nerve innervates the skin of the palmar side of the nail bed.
