Question 39

cervical plexus

Answer 39

The cervical plexus is a complex neurologic structure located within the head and neck. The large portion of the cervical plexus is the communication between the anterior divisions of C1 through C4 nerves.

Question 40

brachial plexus

Answer 40

A network of nerves that provides movement and feeling to the shoulder, arm and hand. The nerves supporting the arm exit the spinal column high in the neck; those that support the hand and fingers exit lower in the neck.

Question 41

lumbar plexus

Answer 41

The lumbar plexus is an essential collection of nerves that arise from mostly the lumbar spinal cord.

Question 42

sacral plexus

Answer 42

The sacral plexus is a network of nerve fibres that supplies the skin and muscles of the pelvis and lower limb. It is located on the surface of the posterior pelvic wall, anterior to the piriformis muscle. The plexus is formed by the anterior rami (divisions) of the sacral spinal nerves S1, S2, S3 and S4.

Question 43

thoracic plexus

Answer 43

These nerves mainly supply the skin over the chest and intrinsic back muscles of the thoracolumbar region. The thoracic nerves also supply some of the areas of skin over the abdomen and axilla.
