Nervous System

3. Tissue provides support for the body and connects its parts
6. fluid bathes brain and spinal cord in fluid; acts as a shock absorber; allows for exchange of nutrients and waste between blood and nervous tissue
7. Tissue enables the body to move with the help of bones
8. receives messages from sensory receptors and relays to proper part of cerebrum
11. Nervous System part of motor division; regulates conscious activities
12. Stem connects brain to the spinal cord; controls information going in and out of the brain; controls involuntary actions
16. short branched extensions that carry impulses towards the cell body
17. Nervous System part of motor division; regulates involuntary activities
20. cells cells uniquely suited to perform a particular function
23. System controls and coordinates functions throughout the body and responds to internal and external stimuli; system
24. Body largest part of the cell; contains cytoplasm and nucleus; controls metabolic activity

1. Sheath insulating membrane around axon; creates nodes; keeps impulses moving along the axon = more efficient
2. Nervous System all neurons in the rest of the body that are not included in the brain or spinal cord
4. contained in sacs in axon terminals; released to cause stimulus in the next cell; chemicals
5. control center for recognition of hunger and thirst; coordinates nervous and endocrine systems
6. second largest part of the brain; located at the back of the skull; coordinates balance and movement
9. thick filaments in muscle cells; found in myofibril
10. largest part of the brain; responsible for voluntary and educated actions; divided into frontal, parietal, occipital, and temporal lobes
13. cord controls reflexes; carries signals from brain to the rest of the body
14. cells that transmit impulses
15. the process by which organisms keep internal conditions constant despite external changes
18. Nervous System relays messages, processes information; and analyzes information
19. Tissue transmits nerve impulses throughout the body
21. Tissue includes glands and tissues that cover interior and exterior body surfaces
22. long fiber that carries impulses away from the cell body
