CHAPTER 35: Nervous System 35-3: Divisions of the Nervous System

Central Nervous System Central nervous system –relays messages –processes information –analyzes information

The Brain Brain: made of neurons –controls daily operations of human body –controls homeostasis –interprets sensory information

Cerebrum: largest part of brain controls the conscious activities of the body Brain Stem: links cerebrum with spinal cord The Brain Cerebellum: coordinates muscle contraction

Thalamus & Hypothalamus Thalamus: relays messages Hypothalamus: maintains homeostasis Pituitary Gland: Regulates puberty

The Spinal Cord Spinal Cord: link between the brain & rest of the body Reflexes: involuntary movements Reflex arc: pathway your reflex impulse travels –knee tapped –sensory receptor sends impulse to spinal cord –triggers motor neuron- muscle contracts

The Peripheral Nervous System SENSORY DIVISION –Sends impulses from sense organs to central nervous system MOTOR DIVISION –Sends impulses from central nervous system to muscles or glands –2 parts Somatic System Autonomic System Ex: sight, touch

Somatic & Autonomic Nervous Systems Somatic Nervous System –Activities like movement of skeletal muscle –Under conscious control Autonomic Nervous System –Involuntary, unconscious control –2 parts Sympathetic –Helps body respond to stress Parasympathetic –Keeps body maintaining homeostasis
