(Medical Xpress)—The nervous system is host to some of the most sophisticated cellular structures found anywhere in the body. The orderly phalanxes of sterocilia which arm the ear's inner hair cells, and the photosensitive ...
(Medical Xpress)—When minor wounds heal, the fine nerve endings that sense touch, or control sweating, are usually able to regrow. Like many processes in the body, the ability to regenerate new tissues changes throughout ...
(Medical Xpress)—When Descartes turned his critical eye to the nervous system, he reasoned that the nerves must transduce hydraulic power to control the musculature. In the circulatory system, blood is pushed comparatively ...

The peripheral nervous system is comprised of all nerves outside of the brain and the spinal cord (i.e., the central nervous system). Peripheral nerves contain a variety of different cell types, including glial cells.
(Medical Xpress)—Neurons have developed elaborate mechanisms for transporting critical components, like transmitter-laden vesicles, down their axons to the synaptic terminations. An axon in a blue whale may be several meters ...
(Medical Xpress)—It is widely know that the grey matter of the brain is grey because it is dense with cell bodies and capillaries. The white matter is almost entirely composed of lipid-based myelin, but there is also a ...
Two Northwestern University neuroscientists have identified the neurochemical signal likely missing in Parkinson's disease by being the first to discover two distinctly different kinds of neurons that deliver dopamine to ...
