3 basic parts of the neuron - ✔✔✔cell body, dendrites, axon
3 different types of neurons - ✔✔✔multipolar, bipolar, pseudounipolar
endoneurium - ✔✔✔dense irregular connective tissue that surrounds each nerve fiber
perineurium - ✔✔✔irregular connective tissue that surrounds each fascicle
epineurium - ✔✔✔delicate irregular connective tissue that surrounds the entire nerve
astrocytes - ✔✔✔blood brain barrier, star shaped cell
microglia - ✔✔✔Act as phagocytes, eating damaged cells and bacteria, act as the brains immune system
oligodentrocyte - ✔✔✔produce myelin in the central nervous system
Schwann cells - ✔✔✔produce myelin in the peripheral nervous system
Ependymal cells - ✔✔✔produce cerebrospinal fluid
excitability - ✔✔✔ability to respond to stimuli
conductivity - ✔✔✔the ability of the cell to carry the excitation response along the length of the nerve
cell axon
threshold - ✔✔✔When the depolarization reaches a point that is irreversible
, the main cation in the nerve cell - ✔✔✔potassium
The extracellular compartment has a relatively high concentration of ( 1. ) and low concentration of ( 2. )
- ✔✔✔1. sodium (Na+) 2. potassium (K+)
potential is maintained at rest by - ✔✔✔sodium-potassium pump
the basic division of the nervous system (2) - ✔✔✔CNS and PNS
the brain - ✔✔✔a complex mass of nerve, connective, and epithelial tissue
the four anatomic and functional regions - ✔✔✔cerebrum, diencephalon, cerebellum, brainstem
The brain contains a system of fluid filled cavities (spaces) called the - ✔✔✔ventricles
ventricles - ✔✔✔filed with cerebrospinal fluid (CSF), which is derived from the plasma, and serves to
protect the brain by allowing it to float in the insulating fluid of the CSF
The brain and spinal cord are surrounded by a set of three membranes, collectively known as the -
✔✔✔meninges
the 3 layers of meninges - ✔✔✔dura mater, arachnoid mater, pia mater
falx cerebri - ✔✔✔the meningeal layer of the dura mater that separates the two cerebral hemispheres
tentorium cerebelli - ✔✔✔separates cerebrum from cerebellum
fissures - ✔✔✔deep grooves in the brain
