Central Nervous System
Includes the
brain
and
spinal cord
Peripheral Nervous System
Consists of all nerves and ganglia outside the
CNS
Sensory nervous system
Afferent
nervous system
Motor nervous system
Efferent
nervous system
Somatic motor
nervous system
From CNS to voluntary muscles
Autonomic motor
nervous system
From CNS to involuntary muscles
Sympathetic
autonomic
nervous system
Fight or flight
Parasympathetic
autonomic
nervous system
Rest and digest
Enteric
Nervous System
Has motor and sensory neurons contained wholly in the digestive tract
Multipolar neurons
Most neurons
Bipolar neurons
Found in the retina and nasal cavity
Pseudo unipolar neurons
Found in the dorsal root ganglion
Astrocytes
Major supporting cell, blood-brain barrier
Ependymal cells
Produces CSF
Microglia
Immune cells
Oligodendrocytes
Myelin sheath of the CNS
Schwann cells
Myelin sheath of the PNS
Multiple sclerosis
Potentially disabling disease of the
brain
and
spinal cord
Multiple
sclerosis
- the immune system attacks the protective sheath (myelin) that covers axons
Gray matter
40
% of the brain, contains most of the brain's neuronal cell bodies, serves to process information, fully develop once a person reaches his
20's
White matter
60
% of the
brain
, made of bundles which connects various gray matter areas, develop throughout the 20's and peaks in middle age
Saltatory conduction
Action potential appears to jump from node to node
Acetylcholine
A neurotransmitter for memory and cognitive function. It also gives bowel tone.
Norepinephrine
A neurotransmitter for attention, motivation, pleasure, and reward.
Dopamine
The reward chemical. A neurotransmitter for alertness and energy.
Serotonin
The mood stabilizer. It helps to regulate mood and behavior, appetite, digestion, sleep, memory, and sexual drive.
Oxytocin

Seasonal
affective
disorder
(SAD) is a type of depression that comes on in the winter months when the sun is sparse.
Alzheimer's
disease: most common form of dementia and is associated with a decrease in Acetylcholine-secreting neurons.
Myasthenia
gravis
: results from reduction in acetylcholine receptors
Botulism
: caused by toxin of Clostridium botulinum and blocks the release of acetylcholine from the presynaptic terminal.
Cocaine
: acts by inhibiting the reuptake of norepinephrine.
Morphine
: mimics endorphins, the "happy hormone".
