Nervous System

2. the thin layer of tissue forming the natural outer covering
5. a region of tissue, or a molecule in a cell membrane, that responds specifically to a particular neurotransmitter
9. a junction between two nerve cells, consisting of a minute gap across which impulses pass by diffusion of a neurotransmitter.
10. nerve cell that transmits sensory information
11. the part of the brain at the back of the skull in vertebrates. Its function is to coordinate and regulate muscular activity.
12. is responsible for the integration of complex sensory and neural functions and the initiation and coordination of voluntary activity in the body
13. a faculty by which the body perceives an external stimulus
14. the long threadlike part of a nerve cell along which impulses are conducted from the cell body to other cells.
16. a short branched extension of a nerve cell, along which impulses received from other cells at synapses are transmitted to the cell body
18. a specialized cell transmitting nerve impulses; a nerve cell.

1. conducted or conducting outward or away from something
3. a neuron that transmits impulses between other neurons, especially as part of a reflex arc
4. the inner region of an organ or tissue, especially when it is distinguishable from the outer region or cortex
6. the sensation of flavor perceived in the mouth and throat on contact with a substance
7. the nervous system outside the brain and spinal cord
8. a nerve cell forming part of a pathway along which impulses pass from the brain or spinal cord to a muscle or gland
9. any agent, act, or influence which produces functional or trophic reaction in a receptor
11. the nucleus-containing central part of a neuron exclusive of its axons and dendrites that is the major structural element of the gray matter of the brain and spinal cord
15. the complex of nerve tissues that controls the activities of the body. In vertebrates it comprises the brain and spinal cord
17. an action that is performed as a response to a stimulus and without conscious thought
