Nervous System

The two major parts of the nervous system are the

• brain and spinal cord

• central and somatic nervous systems

• sympathetic and parasympathetic systems.

• peripheral and central nervous systems

The speed of neural conduction between neurons will result in difficulties in speaking, vision, and balance if the ________________ insulating the axons is damaged or removed.

• Axon

• Myelin Sheath

• Nucleus

• Brain

Dr. Vazquez is examining a cell from the nervous system of an animal. He notices that at one end of the cell body is a long, fibrous strand of tissue. He immediately recognizes this as an axon that is responsible for

• carrying signals away from the cell body

• receiving signals from other cells and carrying them toward the cell body.

• determining the speed at which an action potential will travel

• determining whether the cell inhibits or excites neighboring neurons
