Anatomy

the BRAIN, and neurons

cerebrum

cerebrum

largest part of the brain, interprets sensory information, reasoning and learning

cerebellum

Balance and coordination

Brain Stem

Connects the brain and spinal cord, autonomic function, and heart rate

Diencephalon

relays sensory information

pineal gland

sleep cycles

corpus callosum

Connects the left & right hemispheres.

midbrain

visual and auditory data processing

medulla oblongata

regulating breathing and heart rate

Hypothalamus

maintaining homeostasis by directing the pituitary

superior colliculus

body orientation and eye movements

thalamus

relays information to the correct area of the brain

pons

regulating sleep cycles, respiratory processes and motor control

centeral nervous system

brain and spinal cord

peripheral nervous system

peripheral nerves though body

somatic nervous system

skeletal, volentary

autonomic nervous system

smooth muscles, glands, involentary

Parasympathetic

rest and digest

sympathetic

fight or flight

Myelinated (white matter)

myelinated axons

Unmyelinated (grey matter)

unmyelinated axons

agonist

molecule that has the same effect on the neuron as the original neurotransmitter, it mimics the molecule

antagonist

molecule that blocks the effect of a neurotransmitter

ALS

degeneration of nerve cells in the spinal cord and brain

Epilepsy

excessive electrical activity in brain

myasthenia gravis

antibodys destroy neurons connections

Oligodendrocytes

make myelin sheath

Astrocytes

connect blood vessels to neurons

microglial cells

immune function; digest debris, kills bacteria

myelin sheath

insulation for neuron
