"Bad men need nothing more to compass their ends, than that good men should look on and do nothing," said the British philosopher John Stuart Mill in his 1876 address to St Andrews University. Not in the moral remit, but in the physiological context, astrocytes certainly do more than "loo...
Ependymal cells produce CSF (cerebrospinal fluid), which is located within the ventricles of the brain and in the subarachnoid space that surrounds the brain and spinal cord. Aside from allowing the brain to float in the skull, CSF acts as a cushion against traumaand also helps wash away some...
The P-gp immunosignal, associated with RG-like NPCs during cortical histogenesis, progressively decreases in parallel with the last waves of neuroblast migrations, while 'outer' RGCs and the deriving astrocytes do not stain for the efflux transporter. These data suggest that in human glioblastoma ...
In the Central Nervous System: 1. Grey matter is composed of cell bodies, dendrites, unmyelinated axons, protoplasmic astrocytes, satellite oligodendrocytes (non-myelinating oligodendrocyte subtype), microglia, and very few myelinated axons. 2. White matter is composed of myelinated axons, fibrous...
What does the myelin sheath do in the nervous system? Are astrocytes neurons? What type of myelin is in the peripheral nervous system? What is the gap at the junction between two neurons? What myelinates axons in the peripheral nervous system?
What is the function of the parasympathetic division of the autonomic nervous system? What effects does it have on the body? Name and explain three functions of the skeletal system. Explain the functions of astrocytes in a normally functioning nervous system. ...
Microglia and astrocytes play essential roles in the central nervous system contributing to many functions including homeostasis, immune response, blood-brain barrier maintenance and synaptic support. Evidence has emerged from experimental models of glial communication that microglia and astrocytes influence an...
