CNS |
Is made up of brain and spinal cord. The neurons that make up the CNS are called Interneurons |
|
PNS |
Is made up of all nerve fibers that take information to and from the CNS. Neurons that make up the PNS are called receptors and effectors. |
|
Receptors |
Generate electrical impulses & take information to the CNS. Also called senosry neurons or afferent neurons. |
|
Effectors |
Take messages away from the CNS to organs, muscles, etc. Also called motor neurons or efferent neurons. |
|
Somatic |
Controls voluntary muscle movement. |
|
Automonomic |
Controls glands, Internal organs & Involuntary muscles. |
|
Sympathetic |
Prepares body for emergencies. |
|
Parasympathetic |
Helps the body to recover from strenous activity or arousal from sympathetic. |
|
Action Potential, Hyperpolarized & Depolarized |
Electric activity in neurons is strenghtened. |
|
Resting Potential |
The cell is alive & active, but not transmitting. |
|
Neurotransmitters |
Chemical released to other neurons to arouse them. |
|
Reuptake |
Neurons reabsorbing/ recycle neurotransmitters. |
|
Enzyme Breakdown |
Breaks down chemicals into other substances. |
|
Receptor Sites |
Where neurons recieve neurotransmitters. |
|
Nerotrasmitters |
1.) Serontonin 2.) Dopamine 3.) Endophrine 4.) Norepinephrine 5.) Acetycholine 6.) GABA |
