Practice exam for Biological
psychology with answers
1. The nucleus of the nerve cell is located within the
a. soma.
b. axon.
c. axon terminals.
d. dendrites.
e. mitochondria.
The right answer is A.
- The soma is the cell body of the nerve cell.
- The axon sends signals to other neurons and terminates in the axon terminals.
- The dendrites receive information from other cells.
- The mitochondria is the power house of the cell. It makes ATP and is located in the cell soma.
2. The _______ are the key supply source of energy for neurons.
a. phagocytes
b. Schwann cells
c. dendrocytes
d. astrocytes
e. microtubules
The right answer is D.
- Astrocytes make contact with blood vessels to take up glucose so they can give this to the
nerve cells. The nerve cells use this glucose to make ATP.
- Phagocytes engulf and break down dead and dying neurons. This is done by microglia cells.
- Schwann cells are important for making the myelin sheath around axons in the peripheral
nervous system.
- A dendrocyte is a dendritic cell that originates in bone marrow.
- Microtubules are the road system for transportation of neurotransmitter through the axon.
3. Myelination of brain nerve axon membranes is accomplished by
a. oligodendrocytes.
b. microglia.
c. astrocytes.
d. neurocytes.
e. Schwann cells.
The right answer is A.
- Oligodendrocytes form the myelin sheath around axons in central nervous system.
- Microglia are important for the immunologic defense in the brain and removal of dead cells.
- Astrocytes are important for structure and solidity between neurons, and they also isolate
the synaptic clefts, so the neurotransmitters are not distributed through the whole brain.
- Neurocytes is another word for neurons, and they convey electrochemical impulses.
