NERVOUS SYSTEM Q & A
1. What are two forms of communication that are used to maintain homeostasis?
2. What are the three steps to reforming balance through the nervous system?
3. What are two systems that the nervous system is divided into?
4. Name the parts of the peripheral nervous system.
5. Name the parts of the central nervous system.
6. Name the parts of the nerve cells.
7. Give the functions of the following parts of the neurons:
a. Dendrites-
b. Axon-
c. Synapsis
d. Axon hillock
1. Fill in the blanks of the following passage.
The _____ is initiated by tapping the tendon connected to the quadriceps (extensor)
muscle. _______ detect a sudden stretch in the quadriceps. ________ convey the
information to the spinal cord. The__________ neurons communicate with
_____________ neurons that supply the quadriceps. These signals cause the quadriceps
to contract, jerking the lower leg forward. ___________ neurons from communicate with
the ____________ in the spinal cord. The __________ can inhibit _________ that supply
the hamstring (flexor) muscle which will then resist the action of contracting.
2. What is the name of the cells that are responsible for the structural integrity of the nerve
cells and normal functioning of the neurons?
3. Name 4 types of glial cells that form part of the nervous system.
4. Provide the name of cells that provides structural support for neurons and regulate the
extracellular concentrations of ions.
5. What is the name of the cells that forms tracks along which newly formed neurons use to
migrate from the neural tube?
6. Oligodendrocytes forms myelin sheaths around axons of many vertebrate neurons in the
central nervous system (CNS) / peripheral nervous system (PNS).
7. Schwann cells form myelin sheaths around axons of many vertebrate neurons in the
central nervous system (CNS) / peripheral nervous system (PNS).
8. Name three functional types of neurons.
9. What part of neurons is responsible for the increase in speed of transmission of neurons?
10. Give one sentence to explain membrane potential.
11. What is responsible for maintaining the resting potential of a neuron.
12. In neurons, the membrane potential is typically between -60 and -80 mV (millivolts)
when the cell in not transmitting signals.
Provide an explanation for the minus sign.
13. _________________ is the name of the membrane potential of a neuron that is not
transmitting signals.
