What are the components of nerve tissue?

Nerve tissue is primarily composed of two key components: neurons and glial cells (or neuroglia). Neurons are the functional units of the nervous system, responsible for transmitting signals and processing information. Glial cells support, protect, and nourish neurons, playing critical roles in maintaining homeostasis, forming myelin, and participating in signal transmission.

While option C mentions connective tissue cells, it's important to note that glial cells fall under the broader category of connective tissue in this context, as they function to support the neurons. Thus, the essential components of nerve tissue include both the neurons and glial cells, aligning with the understanding that nervous tissue is not solely made up of neurons or just glial cells, but rather a combination of both to form a complex and functional network.

The other choices either focus solely on one type of cell or include incorrect cell types that do not belong to nervous tissue, such as skeletal muscle cells, which serve a completely different function in the body related to movement and are not part of the nervous system.
