Schwann Cells

Schwann cells are a type of glial cell located in the peripheral nervous system, responsible for the formation of myelin sheaths around neurons, which helps speed up the transmission of nerve impulses.

Fascicle

A bundle of skeletal muscle fibers surrounded by connective tissue, contributing to the structure and function of muscles.

Neurofibrils

Fine, thread-like structures within neurons that provide support and nutrient transportation throughout the nerve cell.

Node of Ranvier

Gaps in the myelin sheath of a nerve fiber, allowing for rapid conduction of nerve impulses.
