Functions of the Nervous System • Control • Regulate • Communicate • Mental activity center: • Learning • Memory • Homeostasis
Main Parts of the Nervous System • The nervous system is made of: • The encephalon **The nerves • The spinal cord The senses
Central Nervous System • The Central Nervous System controls everything in the body. • It contains the nerves of the encephalon and spinal cord
General Division of the encephalon The Encephalon has three main parts: 1. The Cerebrum 2. The Cerebellum 3. The Brainstem
The Cerebrum • The Cerebrum is the largest part of the encephalon. • It identifies the information gathered by your sense organs. • It is protected by the skull • The cerebrum controls yours: • Thinking • Memory • Speaking • Movements
TheCerebellum The cerebellum is below and to the back of the cerebrum. The cerebellum controls your: Balance Posture
The Spinal Cord The spinal cord sends messages to the brain. The spinal cord is the part of the nervous system that connects the brain to the rest of the nervous system.
PeripheralNervousSystem controls
interneuron or Mixed neuron Carry impulses from sensory nerves to motor nerves.
Peripheral NervousSystem The peripheral nervous system is made of the senses organs, those organs are:
