- Limbic System
- Midbrain
- RAS
- Substantia Nigra
- Hindbrain
- Medulla Oblongata
- Pons
- Cerebellum
- Peripheral Nervous System (PNS)
- Autonomic Nervous System
(ANS)
- Sympathetic NS
- "Gas" "Accelerates"
- Prepares for "fight-or-flight"
- e.g., increased HR, pupil dilation, conversion of
energy stores (fat and glycogen) to glucose
- Parasympathetic NS
- "Brakes" "Deactivates"
- Responds to SNS creating states
of relaxation
- e.g., decreased HR, activation of digestion & elimination,
conversion of glucose to energy stores (glycogen & fat)
- Regulates Involuntary Movements
- e.g., Digestion, Respiration, Heartbeat & Autonomic Arousal
- Somatic Nervous System
(SNS)
- Voluntary Movement
- Relays signals from senses
- Controls Skeletal Muscles
- Afferent Nerves - "Sensory or Receptor" nerves,
carry info from SENSE ORGANS to CNS
- Efferent Nerves - "Motor or Effector" nerves,
carry info from CNS to MUSCLES & GLANDS
