Nervous System (Action Potential (Step 1: A stimulus causes Na+ gates to…

- - - - Temporal Lobe
        
        Hearing, speech, memory, sequencing, and organization
      - Parietal Lobe
        
        Pain, temp.
      - Frontal Lobe
        
        Personality, emotions, intelligence, attention, concentration, logic, and problem solving
      - Occipital Lobe
        
        Processes vision (Visual Cortex)
  - - - Reflex center for vision and hearing
    - - Relay between cerebrum and cerebellum
    - - Reflex center for heart rate, B.P. breathing, vomiting, and swallowing
  - - - Contains:
        
        Thalamus
        
        Relays sensory info., recognizes good v. bad sensation
        
        Hypothalamus
        
        Controls body temp., water balance, metabolism, and endocrine function
- - - - Relay information from skin, muscles, and glands to CNS
    - - Carry impulses from CNS to organs, muscles
      - 2 types:
        
        Automatic motor neurons
        
        Unconscious, involuntary control and responds to internal environment
        
        Somatic motor neurons
        
        Conscious voluntary control and senses/ responds to external environment
- - - - Spinal Cord Reflex = Results from conduction over arcs in the spinal cord
        
        Withdrawal and Jerk reflex
      - Interneuron allows for reflex to happen
    - - Ascending Tracts= send sensory impulses to brain
      - Descending Tracts= send motor impulses
