Parts that compose the Nervous System
Brain, Spinal Cord, Nerves
Parts that compose the Central Nervous System
Brain and Spinal Cord
Parts that compose the Peripheral Nervous System
Nerves
A set of three tough membranes that encase the Central Nervous System
Meninges
The outer and toughest layer of the meninges
Dura Mater
,The middle layer of the meninges. Has a spider-like vascular system.
Arachnoid Layer
The innermost layer of the meninges. Rests directly on the brain and spinal cord
Pia Mater
Where is cerebrospinal fluid found?
Between the arachnoid and pia mater layers
Produces cerebrospinal fluid
Choroid Plexus Cells
Interconnected hollow areas of the brain where cerebrospinal fluid fills and flows freely
Ventricles
Cells that regulate interstitial fluid, defend neurons against pathogens, and assists in neural
repair.
Neuroglia
Cells that myelinate neurons in the peripheral nervous system
Schwann Cells
,Nerve cells require a constant supply of what?
Oxygen and glucose
Transmits impulses away from the cell body
Axons
Transmits impulses towards the cells body
Dendrites
Tiny bulges at the end of the axon that communicate with neurons, muscle fibers, or glands.
Terminal Boutons.
Surrounds some axons and increases the rate of impulse transmission
Myelin Sheath
Site of nutrient exchange where myelin is not present
Nodes of Ranvier
, Gaps between neurons
Synapses
What generates neural impulses?
Small ionic changes due to potassium and sodium ions
The charge created by small ionic changes
Action Potential
Charge at rest due to sodium ions concentrated on the outside of the cell
Resting Potential
A rapid flow of positively charged potassium ions into the cell due to stimulated neurons opening
protein gates
Depolarization
Commons Neurotransmitters
Acetylcholine, dopamine, norepinephrine, serotonin, glutamate, gamma aminobutyric acid,
endogenous opioids.
