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
