| Question | Answer |
|---|---|
| spinal column | backbone |
| neurons | nerve cells |
| synapse | space between neurons |
| hormones | chemical messengers used by the endocrine system |
| reflex | happens before the brain has time to think about it |
| target cells | programmed by genes to recieve only a certain hormone |
| multiple sclerosis | nervous system disorder that destroys the myelin sheaths on some neurons causing impulses to be unable to move through the nervous system |
| epilepsy | nervous system disorder that causes the brain to send electric impulses to quickly and irregularly |
| parkinsons disease | nervous system disorder that damages brain cells that control movement |
| pituitary gland | gland that produces hormones that control other glands |
| thyroid gland | gland that controls how food and energy is stored |
| T\F Target cells are programmed by the vertebrae to recieve only a certain hormone | T |
| T\F the neurons in the hypothalmus regulate the pituitary gland | T |
| T\F the pancreas controls how energy from food is used and influences growth | F- thyroid gland |
| T\F Epilepsy occours when the brain sends electrical impulses to quickly and irregularly | T |

| influences growth and development | thyroid gland |
| detects odor particles | olfactory receptor |
| carries impulses from the ear to the brain | auditory nerve |
| damage is caused to the brain cells that control movement | Parkinsons disease |
| carries nerve impulses from the retina to the brain | optic nerve |
| destroys myelin sheaths on some neurons causing impulses to stop moving | multiple sclerosis |
| regulates the pituitary gland | hypothalmus |
| can cause elctrical impulses to be sen to quickly or irregularly | epilepsy |
| the largest part of the brain is the _______ | cerebrum |
| cells that are programmed to recieve only one hormone are called ______ _____ | target cells |
| T\F the brain and the spinal cord are part of the endocrine system | F |
| T\F axons recieve impulses from other neurons | F |
| The axon sends the impulse to the next neuron | T |
| T\F the nervous system remains inactive while a person sleeps | F |
| T\F neurons in the hypothalmus help regulate the pituitary gland | T |
| T\F the pituitary gland produces hormones that control other glands in the endocrine system | T |
| How does REM sleep important to our body? | it helps our brain organize and sort information and it helps us develop |
| how does the hypothalmus relate to the endocrine system? | the hypothslmus is located near the base of the brain and it helps regulate the pituitary gland |
