The cells of the nervous system are quite fragile and need extensive protection from being crushed, being infected by disease organisms, and other harm. The brain and spinal cord are covered by a tough, translucent membrane, called the dura mater. Cerebrospinal fluid (CSF) is a clear, watery...
Davson (33) has described the concepts of the blood-brain barrier and the circulation of the CSF. The brain and spinal cord are surrounded by the CSF. In the interior of the brain the ventricular systems exist, containing the CSF, which connects to the external fluid by a hole in the ...
and extends along the head-to-tail plane becoming the spinal cord and brain. 25 days into its development, the embryo has a distinct spinal cord, as well as hindbrain, midbrain and forebrain (Stiles & Jernigan, 2010). What, exactly, is this nervous system that is developing and what ...
It not only routes messages to and from the brain, but it also has its own system of automatic processes, called reflexes. The top of the spinal cord merges with the brain stem, where the basic processes of life are controlled, such as breathing and digestion. In the opposite direction, ...
Microglia are a cell type, that is only found in the CNS (Central Nervous System; per human definition: brain and spinal cord). Usually microglial cells are in a so called ramified state, in which they are immunologically inactive. However they can be “activated” via various triggers (all...
