nervous system cells Flashcards
astrocytes
CNS cells that give neurons structure, regulate material passage, and provide support by winding around neurons and blood vessels.
astrocytes

ependymal cells
CNS cells lining the spinal and brain cavities from their apical surface.
Help secretion and circulation of CSF( cerebral spinal fluid).
oligodendrocytes
CNS cell that wraps around neurons.
produces MYELIN- a phospholipid insulation.
microglia cells
CNS cells that engulf and attack potential pathogens and threats.
stem from white blood cells.
Neuroglial/ Neuroglia cells
Cells in the CNS and PNS that do not carry information but aid neurons. most often form cancer and tumors due to being highly mitocally active.
satellite cells
the astrocyte cells of the PNS
form ganglia that regulate oxygen, carbon dioxide, neurotransmitters, and nutrients
Schwann cells
the oligodendrocytes of the PNS
produces myelin that increases the speed of impulses and provides insulation
Neuron
specific cells in PNS and CNS that are able to send, receive, and respond to impulses
soma
the cell body of neurons
contain special ERs that manufacture neurotransmitters
dendrites
the receiving end of a neuron that recept impulses
axon
extension of the soma that contains neurotransmitters and carries on impulses
axon hillock
edge fo cell body that begins axon
axon terminals
branched out distal ends of the axon with end bulbs that contain vesicles of neurotransmitters
afferent neurons
send impulses into the CNS
give us sensations
