Anatomy

2. Made up of two hemispheres separated by the median longitudinal fissure and from the cerebellum by the transverse fissure
4. Separates the cerebellum from the cerebral hemispheres
5. diseases that disrupt the normal structural and physiological properties of the nervous system
9. Fiber tract under the corpus callosum is the
11. tactile manipulation and identification of objects
14. the absence of the sense of smell
15. controls muscles of the face, pharynx, larynx, and neck
17. basic building block in the central nervous system
18. Generally, star-shaped cells that are located in both white and gray matter
19. chemical released into the synapse triggered by the nerve impulse arriving at the end of the axon
20. produced by the choroid plexus and is a clear, colorless fluid.
21. Internal awareness of limb position, posture and movement in space
22. The development or evolution of a particular group of organisms
24. Serves more primitive functions that are independent of conscious control
25. Neurons have two processes, one extending from each pole of the cell body – a peripheral process (dendrite) and a central process (axon)

1. short processes projecting from cell body and look like trees; they receive neural signals from other neurons
3. Located between the brainstem and cerebrum
6. tract: contains approximately 30% of the motor fibers, mediates rapid, skilled, voluntary movements of the skeletal muscles (especially the distal end of limbs) through the spinal alpha-motor neurons.
7. surgery removal of pathologic structures that impair nervous system function
8. Some sulci are very deep and are referred to as
10. form the myelin sheath that surround the axons of the CNS
12. colliculi process auditory information
13. includes the spinal cord, brainstem, diencephalon, cerebellum and cerebral hemispheres (“cerebrum”)
16. drooping of the upper eyelid
23. in the PNS, groups of neuronal cell bodies and dendrites
