| There, sciatic branches innervate the biceps femoris, semitendinosus and semimembranosus muscles, and part of the adductor magnus muscle. |
| Spinal nerves innervate the upper extremities within the enlargement in the cervical region between the fifth cervical vertebra and the first thoracic vertebra. |
| Paired nerves from the brain and ganglia innervate the body. |
| This diurnal variation in melatonin synthesis is brought about by norepinephrine secreted by the postganglionic sympathetic nerves that innervate the pineal gland. |
| The peripheral nerves that innervate the body arise from the spinal cord as 31 pairs of segmental spinal nerves. |
| Most neurons of the sympathetic nervous system use noradrenaline as a transmitter, but some, such as those that innervate the sweat glands of the footpad, use acetylcholine. |
