BIOLOGICAL PSYCHOLOGY EXAMQUESTIONS WITH CORRECT ANSWERS
Mitochondria - Answer-Cellular organelle that provides energy for the cells processes
Cell Nucleus - Answer-The center of the cell that contains the chromosomes
Ribosomes - Answer-Structures in the cell body where genetic information is translated
to produce proteins
Endoplasmic reticulum - Answer-network of tubes that transports molecules
Dendrite - Answer-Receptive surface of neuron
Input zone - Answer-Part of the neuron the receives information, usually corresponds
with dendrites
Cell Body, Soma - Answer-Region of neuron that is the nucleus
Integration Zone - Answer-Part of the Neuron that initiates electrical cell activity, usually
corresponds to axon hillock. Determines whether or not an AP is fired
Axon - Answer-A single extension from the nerve cell that carries nerve impulses from
the cell body to other neurons
Conduction Zone - Answer-The part of the neuron over which the nerve's electrical
signal my be actively propagated, usually corresponds to cell's axon
Axon Terminal - Answer-The end of an axon, forms a synapse with another neuron or
another target cell
Output Zone - Answer-The part of a neuron, usually corresponding with the axon
terminals, at which the cell sends information to another cell
Multipolar Neuron - Answer-Has many dendrites and a single axon
Bipolar Neuron - Answer-Has a single dendrite at one end and a single axon at the
other end
Unipolar Neuron - Answer-Has single branch that leaves the cell body and then extends
in two directions, one end is the receptive pole, the other is the output zone
Motoneuron - Answer-Nerve cell that transmits motor messages stimulating a muscle or
gland
,Sensory Neuron - Answer-Directly affected by changes in the environment, such as a
light, odor, or touch
Interneuron - Answer-Neither a sensory or motor neuron, receives input and sends it to
other neurons. Modulates activity of principle neurons
Astrocyte - Answer-Star shaped glial cell with numerous processes (extensions) that run
in all directions
Microglial Cells - Answer-Extremely small glial cells that remove cellular debris from
injured or dead cells
Myelin - Answer-The fatty insulation around as axon, formed by glial cells, improves the
speed of conduction of neural cells
Myelination - Answer-The process of myelin formation
Node of Ranvier - Answer-Gaps between the successive segments of the myelin sheath
where the axon membrane is exposed
Multiple Sclerosis - Answer-Literally means "many scars" disorder characterized by the
widespread degradation of myelin
Oligodenrocyte - Answer-A type of glial cell that forms myelin in the CNS
Schwann Cell - Answer-The glial cell forms myelin in the PNS
Edema - Answer-The swelling of tissue, especially in the brain, response to injury
Arborization - Answer-The elaborate branching of the dendrites of some neurons
Presynaptic - Answer-Referring to the region of he synapse that releases the NT
Postsynaptic - Answer-Referring to the region of a synapse that receives and responds
to NT
Presynaptic Membrane - Answer-The specialized membrane of the axon terminal of the
neuron that transmits information by releasing NT
Postsynaptic Membrane - Answer-The specialized membrane on the surface of a cell
that receives information by responding to NT from a presynaptic neuron
Synaptic Cleft - Answer-The space between the presynaptic and postsynaptic elements
Synaptic Vesicle - Answer-A small spherical structure that contains molecules of NT
, Neurotransmitter - Answer-The chemical released from the presynaptic axon terminal
that serves as the basis of communication between neurons
Receptor - Answer-A protein that captures and reacts to molecules of a NT or hormone
Neural Plasticity - Answer-The ability of the nervous system the change in response to
experience or the environment
Axon Hillock - Answer-A cone shaped area from which the axon originates out of the
cell body. Integration zone of neuron
Axon Colateral - Answer-A branch of an axon from a single neuron
Innervate - Answer-To provide neural input
Axonal Transport - Answer-The transportation of materials from the neuronal cell body
to distant regions in the dendrites and axons, and from the axon terminals back to the
cell body.
Gross Neuroanatomy - Answer-Anatomical features of the nervous system that are
apparent to the naked eye.
Cauda Equina - Answer-The caudal most spinal nerves, which extend beyond the spinal
cord proper to exit the spinal column
Peripheral Nervous System - Answer-The portion of the nervous system that includes
all the nerves and neurons outside the brain and spinal cord
CNS - Answer-Portion of the nervous system that includes the brain and spinal cord
Nerve - Answer-A collection of axons bundled together outside the CNS
Cranial Nerve - Answer-Nerve connected directly to the brian
Spinal Nerve - Answer-A nerve that emerges from the spinal cord
Autonomic Nervous System - Answer-The part of the PNS that supplies neural
connections to the glands and to smooth muscles of internal organs. Autonomic
neurons innervate neurons in ganglia, which in turn innervate target organs
Dorsal Root - Answer-The branch of a spinal nerve entering the dorsal horn of the
spinal cord that carries sensory information from the PNS to the spinal cord
Ventral Root - Answer-The branch of spinal nerve arising from the ventral horn of the
spinal cord that carries motor messages from the spinal cord to the PNS
