Terminal nerve
(Redirected from Terminal nerves)
Terminal nerve
The terminal nerve, also known as nervus terminalis or cranial nerve zero, is a cranial nerve that is often overlooked in the anatomy of the human nervous system. Its existence was discovered in humans in 1914 by German anatomist Gustav Fritsch, but its function remains largely unknown.
Etymology[edit | edit source]
The term "terminal nerve" is derived from the Latin word "terminalis", which means "pertaining to a boundary or end". This is likely due to the nerve's position at the end of the cranial nerve sequence.
Anatomy[edit | edit source]
The terminal nerve is often described as a small and delicate nerve, which is difficult to locate due to its size and position. It is typically found near the olfactory nerve, which is responsible for the sense of smell. The nerve fibers of the terminal nerve are unmyelinated, meaning they lack a myelin sheath, which is a layer that protects most other nerves and aids in the transmission of nerve impulses.
Function[edit | edit source]
The function of the terminal nerve is not well understood. Some studies suggest that it may play a role in the regulation of pheromones, which are chemicals that can influence the behavior of others of the same species. However, more research is needed to confirm this theory.
Related terms[edit | edit source]

- Olfactory nerve: The first cranial nerve, which is responsible for the sense of smell and is often found near the terminal nerve.
