the functions homie Flashcards
Dendrites
-conduct impulses towards cell body
-provide receptive surface for communication with other neuron’s
axon
-conducts impulses away from cell body
myelin
-increases conduction speed of nerve impulses
oligodentrocytres
form myelin sheath around axon in the brain and spinal cord
microglia
small cells that phagocytize bacteria and cellular debris and it produces scar tissue
ependymal cell
produce cerebrospinal fluid in CNS
astrocytes
regulates nutrients and ion concentration
Cerebrum
aids in sensory and motor functions
diencephalon
processes sensory input and controls homeostatic processes
cerebellum
coordinates muscular activity
brainstem
coordinates visceral activity and controls different parts of nervous system
corpus callous
connects the hemispheres in the cerebrum
Thalamus
produces general awareness of sensation such as pain touch and temperature
hypothalamus
regulates heart rate, body temp, arterial blood pressure and controls secretion of hormones from pituitary gland
midbrain
bundles of myelinated nerve fibers that convey impulses to and from higher centres of the brain
pons
regulated the rate and depth of breathing
medulla oblongata
transmits impulses between brain and spinal cord
synaptic knob
responsible for connecting axon and dendrites of neighbouring neutrons
nodes of ranvier
allow for ions to diffuse in and out of the neuron
