Neuron Anatomy Flashcards
What tissue
Nervous tissue
What cell type
Neuron
What cell type
Glial Cells
(neuroglia)
What structure
Cell body (soma)
What structure
Dendrites
What structure
Axon hillock
(Locks onto the cell body (soma))
What structure
Axon
What structure
Schwann cells
(forming myelinated sheath around axon)
What structure
Nodes of ranvier
(unmyelinated sections of axon between Schwann cells)
What structure
Nodes of Ranvier
(unmyelinated sections of axon between schwann cells)
What structure
Axon terminals
(presynaptic terminals)
Name of sheath
Endoneurium
(surrounding myelinated nerve fiber of peripherial nervous system)
What structure
Nucleus
(containing chromosomes)
What structure
Mitochondria
(produce ATP)
(Looks like a bean)
What structure
Nissl bodies (Nissl substance)
(groups of rough Endoplasmic reticulum membrane [make proteins])
What structure
Golgi apparatus
What neuron cell type
Multipolar neurons
What neuron cell type
Bipolar neuron
What neuron cell
Pseudounipolar neuron
Interneuron
Only in CNS
Most numerous neuron (approx 20 billion)
Connects sensory to motor neurons
Plays a role in all higher functions
EX: memory, planning, learning
Sometimes there isn’t a interneuron
Axolemma
Cell membrane of an axon
