Sensory TO the CNS
carries motor commands from the CNS to muscles, glands, adipose tissue (effector tissues)
deactivates or shows down activities of muscles and glands (rest-and-digest response); slowing down of heart rates, pupillary constriction
property of cell that it may create and conduct an electrical current when stimulated;
What cells contribute to the blood-brain barrier and proliferate in response to CNS injury?
CNS cells responsible for physical support and maintaining blood brain barrier, GFAP marker (glial fibrillary astrocyte protein)
CNS (line ventricles of brain and central canal of spinal cord) / Active rolein formation and circulation of CSF
Which of the following supportive cells of the nervous system are part of the blood nerve barrier in the peripheral nervous system? (Mark all that apply)
can’t reproduce (if you loose it, you can’t regrow it), but some specific regions display adult nuerogenesis (hippocampus [memory] and olfactory bulb [keep smelling]
groups of free ribosomes and rough ER. Dark regions in a sagittal section of the brain
bundles of actin filaments
An anatomically distinct collection of sensory or motor neuron cell bodies within the PNS
Brain and spinal cord tissue that appears gray with the naked eye; consists mainly of neuronal cell bodies (nuclei) and lacks myelinated axons.
A material’s opposition to the flow of electric current.
Numerous nerve impulses arriving at a synapse at closely timed intervals exert a cumulative effect
