B. ramus
C. ganglion
D. dermatome

Answer :

Final answer:

A network of interwoven nerves from the spinal cord is called a plexus, which serves crucial roles in connecting various nerves. Plexuses allow for the distribution of sensory and motor fibers to specific body regions, unlike other nerve structural terms. The brachial plexus is a well-known example of this anatomical structure.


Explanation:

Understanding Neural Structures

A network of interwoven nerves from the spinal cord is referred to as a plexus. In anatomical terms, a plexus is defined as a network of interconnected nerve fibers or vessels. For example, nerve plexuses can be found within various regions of the body, including the cervical, brachial, lumbar, and sacral regions, where spinal nerves merge and diverge to innervate specific areas.

These plexuses arise from spinal nerves and give rise to nerves that carry both sensory and motor fibers. An example of a well-known plexus is the brachial plexus, which controls the muscles and sensations of the upper limb. Distinct from other options such as ganglion or ramus, which refer to clusters of nerve cell bodies or branches of nerves respectively, the term plexus specifically highlights the interlinked nature of these nerve networks.
