The brain is the most complex part of the human body. It controls all voluntary and involuntary movement and bodily functions. It communicates with each part of the body through the nervous system, a network of channels that carry electrochemical signals.

Brachial Plexus:

The brachial plexus is a network of nerves, running from the spine. (C5–C8, T1).

Cerebellum:

the part of the brain at the back of the skull in vertebrates. Its function is for coordination of muscles.

Spinal Cord:

the cylindrical bundle of nerve fibers and associated tissue that is enclosed in the spine and connects nearly all parts of the body to the brain, with which it forms the central nervous system.

Musculocutaneous:

supplying the muscles and skin.

Radial Nerve:

The radial nerve is a nerve in the human body that supplies the posterior portion of the upper limb. It innervates the medial and lateral heads of the triceps brachii muscle of the arm, as well as all 12 muscles in the posterior osteofascial compartment of the forearm and the associated joints and overlying skin.

Intercostal Nerves:

The intercostal nerves are part of the somatic nervous system, and arise from the anterior rami of the thoracic spinal nerves from T1 to T11.

Subcostal Nerve:

subcostal nerve n. The ventral branch of the 12th thoracic nerve, supplying parts of the abdominal muscles and giving off cutaneous branches to the skin of the lower abdominal wall and to the gluteal region.

Median Nerve:

The median nerve is a nerve in humans and other animals in the upper limb. It is one of the five main nerves originating from the brachial plexus.

Lumbar Plexus Nerve:

The lumbar plexus is a web of nerves in the lumbar region of the body which forms part of the larger lumbosacral plexus. It is formed by the divisions of the first four lumbar nerves (L1-L4) and from contributions of the subcostal nerve (T12), which is the last thoracic nerve.

Sacral Plexus Nerve:

In human anatomy, the sacral plexus is a nerve plexus which provides motor and sensory nerves for the posterior thigh, most of the lower leg and foot, and part of the pelvis. It is part of the lumbosacral plexus and emerges from the lumbar vertebrae and sacral vertebrae (L4-S4).

Genitofemoral Nerve:

The genitofemoral nerve refers to a human nerve that is found in the abdomen. Its branches, the genital branch and femoral branch supply sensation to the upper anterior thigh, as well as the skin of the anterior scrotum in males and mons pubis in females.

Femoral Nerve:

the largest branch of the lumbar plexus that in humans comes from the second, third, and fourth lumbar nerves and supplies extensor muscles of the thigh and skin areas on the front of the thigh and medial surface of the leg and foot and that sends articular branches to the hip and knee joints

Obturator Nerve:

The obturator nerve in human anatomy arises from the ventral divisions of the second, third, and fourth lumbar nerves in the lumbar plexus; the branch from the third is the largest, while that from the second is often very small.

Pudendal Nerve:

The pudendal nerve is the main nerve of the perineum. It carries sensation from the external genitalia of both sexes and the skin around the anus and perineum, as well the motor supply to various pelvic muscles, including the male or female external urethral sphincter and the external anal sphincter.

Ulnar Nerve:

A nerve that arises from the medial cord of the brachial plexus and gives off numerous muscular and cutaneous branches in the forearm, and supplies the intrinsic muscles of the hand and the skin of the medial side of the hand. Also called cubital nerve.

Sciatic Nerve:

a major nerve extending from the lower end of the spinal cord down the back of the thigh, and dividing above the knee joint. It is the nerve with the largest diameter in the human body.

Muscular branches of the femoral nerve:

arises as a branch of the lumbar plexus, conveying fibers from the second, third, and fourth lumbar nerves through the substance of the psoas muscle and enters the thigh via the retroinguinal muscular space posterior to the inguinal ligament, lateral to the femoral vessels; it arborizes within the femoral triangle into

Saphenous Nerve:

The saphenous nerve is the largest cutaneous branch of the femoral nerve.

Tibial Nerve:

the large nerve in the back of the leg in the lateral and medial plantar nerve also called the medial popliteal nerve.

Common Peroneal Nerve:

a nerve that arises as a branch of the common peroneal nerve where it forks between the fibula and the peroneus longus and that innervates or gives off branches innervating the muscles of the anterior part of the leg, the extensor digitorum brevis of the foot, and the skin between the big toe and the second toe
