motor and sensory needs of the muscles and skin of the body's limbs

Plexuses, referring to the nerve plexuses in both upper and lower limb refer to the collection and grouping of nerves responsible for both sensory and motor input/output in a particular area. For example, the brachial plexus is the collection and arrangement of nerves that arises from the spinal cord area around C5-T1/3 and supplies the innervation for the upper limbs.
The major plexuses of the spinal cord are the cervical plexus (C1-C5), brachial plexus (C5-T1), lumbar plexus (L1-L4), and sacral plexus (L4-S4). These plexuses are networks of nerves that supply motor and sensory function to various regions of the body.
choroid plexuses
Except for T2-T12, all ventral rami branch and join one another lateral to the vertebral column, forming complicated interlacing nerve networks called nerve plexuses. Nerve plexuses occur in the cervical, brachial, lumbar, and sacral regions and primarily serve the limbs (MarieB, 2010 8th ed. pp. 502)

The ventral rami of spinal nerves C1-T1 form the cervical plexus, serving the head, neck, and diaphragm. T12-S4 form the lumbosacral plexus, serving the lower limbs and pelvic region. These plexuses distribute nerve fibers to various muscles and skin areas, allowing for coordinated movement and sensation in these regions.

Cerebrospinal fluid is primarily produced by specialized structures in the brain called choroid plexus, rather than capillary knots. These choroid plexus structures filter blood plasma to create cerebrospinal fluid, which serves to protect the brain and spinal cord.
