GENERAL HISTOLOGY

Detailed explanation-1: -In the thoracic region, the ventral nerve plexus also is connected to the nerve plexuses of costovertebral joints. The dorsal nerve plexus is made up of the nerve plexus associated with the posterior longitudinal ligament.

Detailed explanation-2: -The cervical plexus provides nerve connections to the head, neck, and shoulder. The brachial plexus provides connections to the chest, shoulders, upper arms, forearms, and hands. The lumbar plexus provides connections to the back, abdomen, groin, thighs, knees, and calves.

Detailed explanation-3: -The intercostal nerves are distributed chiefly to the parietes of the thorax and abdomen, and differ from the anterior divisions of the other spinal nerves, in that each pursues an independent course, i. e., there is no plexus formation.

Detailed explanation-4: -Cervical Plexus-Serves the Head, Neck and Shoulders. Brachial Plexus-Serves the Chest, Shoulders, Arms and Hands. Lumbar Plexus-Serves the Back, Abdomen, Groin, Thighs, Knees, and Calves. Sacral Plexus-Serves the Pelvis, Buttocks, Genitals, Thighs, Calves, and Feet. More items •17-Jan-2023
