Nervous System

4. specialized cells that detect changes in the body.
7. carries impulses from all parts of the brain to the body and all parts of the body to the brain.
8. a series of small bones forming the backbone, having several projections for articulation and muscle attachment, and a hole through which the spinal cord passes.
10. is a signaling molecule secreted by a neuron to affect another cell across a synapse. The cell receiving the signal may be another neuron, but could also be a gland or muscle cell.
11. nerve cells that carry electrical messages.
14. an _____________impulse is a surge of electrical activity that allows nerve cells and muscle cells to communicate.
15. this is a challenge one.... do it last- a neurological disease that babies can be born with affects muscle control, movement, and coordination.
17. responsible for muscle tone, balance, posture, and muscle coordination.
18. the type of neuron that sends messages to muscles, organs and glands.
19. a space where information is transmitted between two neurons or between a neuron and another cell, like a muscle cell.
20. connects the brain to the spinal cord and controls automatic functions.
21. is the long single fiber of a neuron that transmits electrical signals away from the neuron's cell body to other neurons, muscles, or glands.

1. the body's state of equilibrium, maintained by the nervous system.
2. the major controlling, regulatory, and communicating system in the body.
3. short branched extensions of a nerve cell which receive the nerve impulse
5. which part of the nervous system is made up of the brain and spinal cord?
6. act as a link between sensory and motor neurons, integrating signals and coordinating responses within the central nervous system (CNS)
9. largest part of the brain-controls memory/reasoning.
12. a reflex is a rapid and involuntary response to a stimulus that helps protect the body from injury. It occurs without conscious thought, bypassing the brain to process the signal in the spinal cord.
13. what is your nervous system trying to maintain when you sweat?
16. the division of the nervous system that contains all of the nervous outside of yout brain and spinal cord is know as the ________________ nervous system.
