Regulation
Nervous system works together with endocrine system to control & regulate all other body
systems
Nervous system
quick to respond with short-term results
Endocrine system
slow to respond but with longer lasting results
gray matter
high concentration of neuron somas- regions of integration
white matter
high concentration of myelinated axons- regions of nerve conduction
presynpatic membrane channel
voltage-gated- release acetylcholine
postsynpatic membrane channel
, sodium-potassium channels- opened by acetylcholine
ependymal cells
produces, circulates, and monitors CSF; line ventricles of CNS
Neuroglia
supporting cells; outnumbered neurons; in CNS
function of neurons
storage and processing of information
astrocytes
maintain blood brain barrier by wrapping around capillary and preventing fluid from leaking
out; in CNS
Oligodendrocytes
produce myelin sheath within CNS
Schwann cells
produce myelin sheath outside PNS
Migroglia
mobile cells that rid of cellular debris, waste products, and pathogens; phagocytes so they
engulf the debris, in CNS
transistors
neurons which fire in regenerative, all or none, fashion
Hippocampus
short term memory
cerebral cortex
long term memory
decussation
nerve fibers that cross from one side of the brain to the other
Do peripheral or central nerves regenerate?
Peripheral because they have Schwann cells
