CENTRAL NERVOUS SYSTEM BRAIN SPINAL CORD

BRAIN is the control center of the entire nervous system SPINAL CORD As a conduit for motor information, which travels down the spinal cord As a conduit for sensory information in the reverse direction As a center for coordinating certain reflexes FUNCTIONS

PERIPHERAL NERVOUS SYSTEM SPINAL NERVES CRANIAL NERVES 31 PAIRS 12 PAIRS

Carries motor, sensory, and autonomic signals between the spinal cord and the body SPINAL NERVES Arise in the brain and serve mostly the sense organs CRANIAL NERVES FUNCTIONS

AUTONOMIC NERVOUS SYSTEM AFFECTS THE AUTOMATIC AND INVOLUNTARY ACTIONS OF THE INTERNAL ORGANS

Nerve cell – Neuron Receive stimulus from any part of the body Carries the stimulus along to the dendrite of another nerve cell

AN IMPORTANT FUNCTION OF THE NERVOUS SYSTEM AN IMPORTANT FUNCTION OF THE NERVOUS SYSTEM PICK UP SENSATIONS OF LIGHT, SOUND, TOUCH, TASTE, HEAT, COLD, PAIN, ETC.
