PLAY
Dendrites
protoplasmic extension of nerve cell that receives impulses (synaptic transmission), connection point for neighboring neurons
Axon Terminals
separated from neighboring neurons by synapse where electrochemical signals are sent (called presynaptic neurons), transmission of axon branches sends receptors to neighboring cells
Schwann's Cell
produced myelin (insulation that surrounds nerve fiber core/axon) and facilitates nerve impulse transmissions
Node of Ranvier
local constriction region in myelinated nerve (formed between two Schwann's cells where action potential occurs) - Battery of cell
Axon
threadlike structure that conducts nerve impulses
Myelin Sheath
insulation that surrounds axon/nerve fiber cores and facilitates nerve impulse transmission, improves travel by axon and is subject to diseases like dementia
Nucleus
maintains health of neuron and makes neurochemicals
Cell Body (soma)
main structure of neuron (location of dendrite branches)
