Nervous System Carries messages to and from the brain and spinal cord and all other parts of the body.
The Nervous System Consists of the: Brain, Spinal Cord & Branching Nerves
The Nervous System is divided into two systems: Central Nervous System & Peripheral Nervous System
The Central Nervous System consists of the: Brain & Spinal Cord
The Brain is a mass of Nerve Tissue
3 Parts of the Brain are: 1. Cerebrum 2. Cerebellum 3. Brain Stem
The Cerebrum Controls: Ability to Memorize, Think, & Learn
The Cerebellum Controls: Coordination of muscle activity.
The Brain StemIncludes the Medulla - and controls Involuntary Actions
The Spinal Cord Is a thick band of nerve cells that extends through the backbone. There are 31 pair of spinal nerves branching from it.
The Peripheral Nervous system consists of Cranial Nerves& Spinal Nerves
There are: 12 Pair of CRANIAL NERVESThere are: 31 Pair of SPINAL NERVES
Spinal Nerves TRANSMIT informationTo & From All Parts of the Body
Neurons Are NERVE Cells. There are 2 types of Neurons: Sensory & Motor Neurons
Sensory Neurons: Carry messages FROM sense organs TO the brain.
Motor Neurons: Carries message FROM THE BRAIN TO MUSCLES & GLANDS
Controls ability to memorize, think, learn Controls coordination of Muscle activity Contains the medulla which controls involuntary actions such as heart rate and breathing
