PSYC 1111 Exam with 100% Correct Answers
What is the central nervous system? - ✔✔The collection of neurons that makes up the brain
and the spinal cord.
What is the peripheral nervous system? - ✔✔The collection of neurons that link the central
nervous system to our skin, muscles, and glands.
What are neurons? - ✔✔Specialized nerve cells that transmit information.
What are the three main parts of a neuron? - ✔✔Dendrite, soma, axon.
What is the myelin sheath? - ✔✔Fatty covering over the axon to insulate it and allow faster
transmission of the electrical signal.
What is the function of the dendrite? - ✔✔Receives information from other neurons and
transmits electrical stimulation to the soma.
What is the function of the axon? - ✔✔It is an elongated fibre that transmits information
from the soma to the terminal buttons.
What is the function of neurotransmitters? - ✔✔They relay information chemically from the
terminal buttons and across the synapses to receiving dendrites using a system similar to the
lock and key.
What are agonists? - ✔✔Drugs that mimic the actions of neurotransmitters.
What are antagonists? - ✔✔Drugs that block the action of a neurotransmitter.
, What are the three divisions of the brain? - ✔✔Hindbrain, midbrain, and forebrain.
What are the four lobes of the cerebral cortex and their function? - ✔✔Frontal (thinking,
memory, judgment), parietal (bodily sensation, touch), occipital (vision), and temporal (hearing
and language).
What is neuroplasticity? - ✔✔The ability the brain has to change as a function of experience
and potential damage.
What is neurogenesis? - ✔✔The formation of new neurons.
What is the function of the motor cortex? - ✔✔To control voluntary movement.
What is the sensory cortex? - ✔✔Cortex that receives and processes bodily sensation.
What is the left cerebral hemisphere responsible for? - ✔✔Language and speech.
What is the right cerebral hemisphere responsible for? - ✔✔Spatial and perceptual skills,
visualization, and the recognition of patterns, faces, and melodies.
What happens if the corpus callosum is severed? - ✔✔Split-brain patient: a patient with two
parts of the brain not connected.
What are lesion studies? - ✔✔Studying the effects of brain lesions on behavior and
cognition.
What is electrophysiological recording? - ✔✔Monitors electrical activity of neurons in
animals.
