The following diagram is provided as an overview of and topical guide to the human nervous system: Human nervous system. Human nervous system – the part of the human body that coordinates a person's voluntary and involuntary actions and transmits signals between different parts of the body.
Cutaneous innervation of the upper limbs is the nerve supply to areas of the skin of the upper limbs (including the arm, forearm, and hand) which are supplied by specific cutaneous nerves. Modern texts are in agreement about which areas of the skin are served by which cutaneous nerves, but there are minor variations in some of the details.
The medial cutaneous nerve of the forearm (also known as the medial antebrachial cutaneous nerve) is a sensory branch of the medial cord of the brachial plexus derived from the ventral rami of spinal nerves C8-T1. It provides sensory innervation to the skin of the medial forearm and skin overlying the olecranon.
The ulnar nerve innervates the muscles of the forearm and hand not innervated by the median nerve. The axillary nerve innervates the deltoid and teres minor. The radial nerve innervates the posterior muscles of the arm and forearm; Collateral branches of the brachial plexus: [13] The dorsal scapular nerve innervates rhomboid major, minor and ...
This nerve continues in the arm, travelling in a plane between the biceps and triceps muscles. At the cubital fossa, this nerve is deep to the pronator teres muscle and is the most medial structure in the fossa. The nerve passes into the forearm. The ulnar nerve, origin C8-T1, is a continuation of the medial cord of the brachial plexus.
Autonomic nervous system's jurisdiction to organs in the human body edit; Organ Nerves [1] Spinal column origin [1]; stomach: PS: anterior and posterior vagal trunks; S: greater splanchnic nerves
These nerves control the functions of the rest of the body. In humans, there are 31 pairs of spinal nerves: 8 cervical, 12 thoracic, 5 lumbar, 5 sacral, and 1 coccygeal. These nerve roots are named according to the spinal vertebrata which they are adjacent to.
