Answer 1

Answer:

1. Electroencephalogram EE
2. Axon
3. Ganglion
4. Pons

Explanation:

1. Electroencephalogram (EEG) is a test used to find problems related to electrical activity of the brain. An EEG tracks and records brain wave patterns.
2. Dendrites are the small extension of nerve cells that receives signals from sensory receptors or other neurons. The long extension of cell body of nerve cell is called as axon that serves to conduct the nerve impulse away from the cell body. The increased diameter of axon results in reduced resistance to local current flow which in turn causes the action potential at its one site to activate the adjacent site.
3. Ganglia are the intermediate structures between the central nervous system and peripheral nervous system.
4. The pons contains nuclei that relay signals from the forebrain to the cerebellum, along with nuclei that deal primarily with sleep, respiration, swallowing, bladder control, hearing, equilibrium, taste, eye movement, facial expressions, facial sensation, and posture.
