Summarize sensory neurons purpose

• CNS neurons that communicate between sensory and motor neurons

• Carry incoming information from the sense receptors to the CNS

• Carry outgoing information from the CNS to the muscles and glands

• Controls the body's skeletal muscles

What would result if you were to sustain damage to your motor cortex?

• Lack of sight

What examples deal with the sympathetic nervous system?

• Laying in bed listening to music

• Rocking back and forth outside

• Hanging off of a cliff

What is the function of the somatic nervous system?

• Controls the glands and muscles of the internal organs

• Controls the body's skeletal muscles

• Arouses the body in stressful situations

• Calms the body to conserve energy

• Medulla oblangata

• Cerebellum

• Basil ganglia

• Hypothalamus

Gaps in the myelin sheath are called _______.
