The nervous system’s two parts work together.

Learn how the central and peripheral nervous systems work together to gather, interpret, and transmit information. Explore the brain's structure and functions, spinal cord control, and nerve pathways. Dive into reflex control, voluntary and involuntary movements, and the sympathetic and parasympathetic nervous systems.

Presentation Transcript

  1. KEY CONCEPT The central nervous system interprets information, and the 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. PNS stimulates a response. • PNS passes impulse to CNS. • CNS interprets impulse. • CNS passes impulse to PNS. • Sensory receptor generates impulse • 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 • Details: is biggest part of brain, what you think of when you see a brain • cerebellum allows for balance • Details: at base of brain, looks like cauliflower • brain stem controls basic life functions • Details: has midbrain, pons and medulla at top of spinal cord

  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. • 1. The somatic nervous system regulates voluntary movements • Details: your moving and motor neurons • 2. autonomic nervous system controls involuntary, functions Details: breaks into sympathetic/parasympathetic • 3. sympathetic nervous system: “fight vs. flight” • -Details: adrenal gland • 4. parasympathetic nervous system: calms the body, • -Details: conserves energy , body at rest…
