Neuron and brain structure
Brain
Cerebellum coordinates muscle movement
Hypothalamus
maintains homeostasis
Thalamus directs
most sensory signals
The brain stem
connect the brain to the spinal cord
Cerebrum
The cerebral cortex contains 10-20% of the brain's neurons
Largest portion of the brain
Neurons
Cell body is where most
organelles are located
Axon
Covered by myelin sheath
Gaps in this are called
nodes of Ranvier
Axon terminal
End of axon
Carries info away from cell body
Dendrites
Receive messages from other neurons
Nucleus
