Nervous system and endocrine system

3 types of neurons?

Sensory neurons, motor neurons, interneurons

Stimulus

Any action that causes a response

Response

Action caused by a stimulus

Reflex

Automatic response to a stimulus

3 main parts of the nervous system?

Brain, spinal cord and brain stem

3 parts of brain?

Cerebellum, cerebrum and medulla

Hormones

Chemical substance that regulates (Controls) body functions

What is the job of the nervous system?

Its the captain of your body- controlls all body activties

Cerebrum

Large part of Brain controls senses, memory and thinking ie. Tasting a hamburger, artistic ability

Reflex arc

Message in a reflex

Gland

Organ that makes chemical substances used or released by body

Medulla

Part of brain that controls heartbeat and breathing rate ie. Controls digestion and circulation etc.

Cerebellum

Part of brain- controls balance/ body motion ie. Tying shoes, kicking a ball

Interneurons

Relay impulses between the sensory and motor neurons

Motor neurons

Relay impulses from the brain or spinal cord to muscles and glands throughout the body

Sensory neurons

See the information, sends impulses to spinal cord and the brain

What is the job of the endocrine system

To help control bodily functions

Endocrine gland

a gland that does not have ducts

Pathway of nerve Impulse

impulses travel by tiny burst of electrical power. When outgoing message reaches end of axon, axon releases special chemical called neurotransmitters, Then message jumps the space between neurons called synapse and continue traveling along dendrites of new neurons
