nervous tissue cells and composition Flashcards
respond to stimuli and conduct nerve impulses; amiotic
neurons
support and protect neurons
glial cells
store the organelles of the cell and regulate production of proteins and lipids needed by the rest of the neuron.
cell body
contains nucleolus
nucleus
site of protein synthesis in the neuron
Chromatophilic substances (Nissl bodies): rough ER
found in neurons, called nissl bodies
chromatophilic substances
neurons can have 1 or many of what
dendrites
recieve signals from other neurons, cunduct those signals to the cell body and integrate information
dendrites
1 of these per nucleus
axon
conducts nerve impulses, transmits signals to other cells, supports health of the neuron
axon
portion of the cell body where the axon originates
axon hillock
what lacks chromatophilic substance
axon hillock
