Mod 11: Neuron Anatomy And Physio Flashcards
What are the two basic types of cells?
Neurons and neurolgia
What are the neurons function?.
Conduct signals in the NS and serve all sensorimotor activities and higher cortical functions
Neuroglia are
Supporting and insulating cells
What do Schwann cells do
Form and lay down the myelin sheath on peripheral nerves and form the axon covering
What are the 3 types of neuroglia in the CNS?
- Oligodendroglia
- Astroglia
- Microglia
What is the oligodendroglia function
Form and lay down myelin sheath
What is the function of Astroglia
Occupy spaces between neural processes in the gray matter and insulate the synapse
What do the microglia function as
Macrophages- remove cell debris
Where is the action potential initiated?
axon hillock
Where do each main axon terminate
Terminates by branching into several terminal processes = telodendron
What does the bouton contain?
Vesicles that contain neurotransmitters substance
- excitatory and inhibitory
Where do each telodendron end
Terminal bouton
Neurons can be classified by what 2 features?.
The number of processes they have and the length of the neuron
What are the 3 types or classes of neurons
- Multipolar neuron
- Bipolar neuron
- Unipolar neuron
Most ____ neurons are found in the brain
Multipolar
