  1. KEY CONCEPT Central nervous system - interprets information peripheral nervous system - gathers and transmits information.

  2. The nervous system’s two parts work together. • The CNS includes the brain, brain stem, and spinal cord. • The PNS includes four systems of nerves.

  3. Sensory receptor generates impulse. • PNS passes impulse to CNS. • CNS interprets impulse. • CNS passes impulse to PNS. • PNS stimulates a response. • The CNS and PNS pass signals between one another.

  4. midbrain Brainstem pons medulla oblongata The CNS processes information. • The brain has three parts. • cerebrum controls thought, movement, emotion • cerebellum allows for balance • brain stem controls basic life functions

  5. midbrain pons medulla oblongata • midbrain controls some reflexes • pons regulates breathing • medulla oblongata controls heart function, swallowing, coughing • The brain stem has three parts.

  6. interneuron motor neurons sensory neuron • sensory neuron sends impulse to spinal cord • spinal cord directs impulse to motor neuron • does not involve the brain • The spinal cord controls reflexes.

  7. The PNS links the CNS to muscles and other organs. • The somatic nervous system regulates voluntary movements. • The autonomic nervous system controls involuntary, functions • sympathetic nervous system: “fight vs. flight” • parasympathetic nervous system: calms the body, conserves energy

  8. A. cerebellum-coordinates and regulates voluntary muscle movement, balance, and posture. b. Medulla oblongata- controls breathing, heart rate, and blood pressure, connects to spinal cord c. thalamus-switching area for sensory impact d. hypothalamus- small are of mid-brain, controls secretions of the pituitary gland e. Corpus callosum- thick band of fibers joining the cerebral hemisphere f. pons-regulates breathing g. Spinal cord-main nerve of the CNS extending down to brain h. cerebrum- largest part of the brain coordinates voluntary activities-thought, reasoning, and memory. i. Pituitary gland-makes and releases hormones responsible for growth and osmoregulation.

  9. Pineal body- small, grayish, cone-shaped, glandular outgrowth from the brain of all vertebrates that produces the hormone melatonin-serotonin levels can impact your sleep cycle • stimulates color change in the epidermis of amphibians and reptiles • Midbrain-
