  of neurons
• 3 types Sensory, Motor, and Interneuron's

• Forebrain 5 main regions Thalamus,
  Hypothalamus, Amygdala, Hippocampus, and Cerebral
  Cortex
• Hindbrain 3 areas Medulla, Cerebellum, and
  Pons
• Midbrain

Sensory Somatic and Autonomic Nervous System

• Somatic
• Autonomic
• Plexus
• Sympathetic

Clinical Practice

• Aids in determining location of a defect in
  nervous system
• Tests
• Menace response
• Pupillary light reflex
• Classic reflex
• Gag reflex
• hearing

Anesthetics and diseases

• block sodium ions across membrane
• Extremely useful
• Surgical purposes
• Ataxia-uncontrollable movement
• Atrophy-muscles shrink
• Listeriosis-infection that affects the brain
