Nervous System

3. are ovoid structures containing cell bodies of neurons and glial cells supported by connective tissue
4. is mainly a collection of neuron cell bodies.
5. the inferior end of he spinal cord and the spinal nerves exiting there resemble a horse’s tail and are collectively
6. is attached to the brainstem by several large connections called cerebellar peduncles.
11. contains nuclei involved in coordinating eye movements and controlling pupil diameter and lens shape.
15. extends from the foramen magnum at the base of the skull to the second lumbar
16. is the part of the brain between the brainstem and the cerebrum.
17. plays a central role in the control of body temperature, hunger, and thirst.
19. provide motor and sensory supply mainly to the structures within the head and neck.
20. is the most inferior portion of the brainstem and is continuous with the spinal cord.

1. also influences mood and registers an unlocalized, uncomfortable perception of
2. communicate between the spinal cord and the body.
7. it consists of a few small nuclei, which are involved in the emotional and visceral response to odors
8. All the spinal nerves contain axons of both sensory and somatic motor neurons and thus are
9. allow neurons to transmit electrical and chemical signals to other cells.
10. consists of myelinated axon.
12. is a fluid-filled space in the center of the cord.
13. is the largest part of the brain, it is divided into left and right hemispheres by a longitudinal fissure.
14. works together with the medulla oblongata to serve an especially critical role in generating the respiratory rhythm of breathing.
18. connects the spinal cord to the remainder of the brain.
