Nervous System Notes
Functions of the nervous system:
Receives information from inside & outside the body.
Controls & directs body’s functions & responses.
Helps maintain homeostasis.
What is homeostasis??? When everything in your body is in balance.
Divided into two parts: Peripheral Body nerves Central NS Brain Spinal cord NW
Peripheral NS Somatic NS- carries messages between brain & body to control voluntary muscles Autonomic NS- Controls organs & involuntary muscles
CNS: Spinal Cord Bundle of nerves that runs down the spine to carry messages between the brain and the rest of the body.
CNS: Nerve Cells (Neurons) Basic functioning units of the nervous system that carry messages called impulses.
Coordinates body activities CNS: The Brain Coordinates body activities Made up of approximately 100 billion neurons NW
A Neuron (Nerve Cell) AXON DENDRITES CELL BODY AXON TIPS Neurons carry information through the nervous system. There are BILLIONS of neurons in your body. They are constantly sending/receiving messages. The message that a neuron carries is a nerve impulse.
Direction message travels A Neuron (Nerve Cell) AXON DENDRITES CELL BODY AXON TIPS Direction message travels AXON – carries the messages down to the AXON TIPS, which sends the message to the next neuron. DENDRITES – receive messages and sends them toward CELL BODY (contains a nucleus).
The Synapse An impulse travels down the axon to the axon tips where it either travels to another neuron or to a muscle or gland to carry out a response. The junction where one neuron can transfer an impulse to another structure is called a synapse.
Kinds of Neurons.. AXON CELL BODY DENDRITES AXON TIPS Three kinds of neurons are found in the body: Sensory neurons pick up stimuli from the outside or inside environment and converts each stimulus into a nerve impulse. Inter-neurons carry nerve impulses from one neuron to another. Motor Neurons send an impulse to a muscle or gland, and the muscle or gland reacts in response.

Color The Brain Color the cerebrum purple Color the cerebellum green Divided into 3 major parts- Color the cerebrum purple Color the cerebellum green brain stem orange
The Brain Divided into 3 major parts- cerebrum cerebellum brain stem
Cerebrum (Cerebral Cortex) Coordinates Thinking & learning Creativity Five senses Memory & emotion Problem-solving Decisions Language & communication Body movements
Cerebellum Coordinates: Senses with other areas of the brain Most voluntary muscle movements Helps maintain balance & muscle tone
Brain Stem Connects brain to spinal cord Coordinates: (involuntary actions) Heartbeat Breathing Digestion Swallowing Blinking
FYI: Huntington’s disease Inherited genetic disease that causes the nerve cells in the brain to waste away.
FYI: Parkinson’s disease Degenerative disease that affects the neurons that control muscle movement.
FYI: Alzheimer’s disease Degenerative disease that affects the areas of the brain that control thought, memory & language.
FYI: Epilepsy Occurs when a cluster of neurons send out the wrong signals and results in seizures.
FYI: Meningitis Inflammation of the tissue that surrounds the brain & spinal cord can be caused by a bacteria or virus.
