Cells of the Nerves Flashcards
Functions of neurons
receives, processes, interprets, generates, and transmits data
Cell bodies are found in the _____ while axons are found in the ______.
Gray matter
White matter
What do Dendrites do?
Collect data about the nervous system
What happens in the cell body?
It is where data is processed, analyzed, interpreted, and generated
What do you call the cell body in the CNS?
Nuclei
What do you call the cell body in the PNS?
Ganglion/Ganglia
What are the functions of glial cells?
Produces myelin
Provides nutrition to neurons
Supports neurons
Secretes CSF (ependymal cells)
Regenerate and fills up void in damaged areas
Gliosis
Where are astrocytes located?
In the gray matter of the CNS
Where are oligodendroglia located?
In the white matter of the CNS
Where are microglia located?
White mater
Where are ependymal cells located?
Lines the walls of cavities and ventricles
What does the Blood Neuronal Barrier/Blood Brain Barrier do?
Protects neurons from toxins in the blood
The last walls are the neuronal membrane
What is the Blood Neuronal Barrier/Blood Brain Barrier made of?
Glial cells wrap around the neuron and blood vessels.
1st defense of Blood Neuronal Barrier
Capillary Membrane
2nd defense of the Blood Neuronal Barrier
Footpads of the Capillary
4th defense of the Blood Neuronal Barrier
Body of proplasm
5th defense of the Blood Neuronal Barrier
Footpads of the neuron
6th defense of the Blood Neuronal Barrier
Black area
It is the connection between neurons
Synapses
The neuronal membrane of the first neuron
Presynaptic membrane
It is the space between two neurons
Synaptic Cleft
The neuronal membrane of the second neuron
Post-synaptic membrane
What are the three types of synaptic connection?
Axo-dendritic
Axo-somatic
Axo-axonic
