CENTRAL NERVOUS SYSTEM

CENTRAL NERVOUS SYSTEM (CNS) Brain and spinal cord Send/receive information along with Peripheral Nervous System (PNS)

PNS CHARACTERISTICS Sensory and somatic (motor) neurons Sends and receives information from CNS

SOMATIC NERVOUS SYSTEM Motor and sensory information Voluntary control of body movement Skeletal muscle

Autonomic Nervous System Part of the PNS Located in medulla oblangata Three parts Parasympathetic NS Sympathetic NS Intrinsic NS

Sympathetic Vs. Parasympathetic (Organs) Eyes Heart Lungs Blood Vessels Sweat Glands Digestive Tract Kidney Cardiac Muscle Digestive System (Salivary Glands) Respiratory System: (Blood Vessels, Lymphatic Vessels, and Nerves)

Responses to Change

Your task: 2 drawings: a situation that stimulates the sympathetic nervous system in you one that stimulates the parasympathetic nervous system in you Rules: Label/show 3 responses for each drawing Color Titles (sympathetic/parasympathetic) on blank white paper only sleep/school can't be used for examples (tell me something I wouldn't already know about you) appropriate for school only
