Cognitive Neuroscience exam #1 questions with
correct answers
Cognitive Neuroscience Correct Answer-Study of the brain and how it
relates to complex thoughts and behaviors
Neurons Correct Answer-Cells that carry information from one place to
another
Sensory Neurons Correct Answer-Bring information to the central
nervous system
Interneurons Correct Answer-associate information within the central
nervous system
Motor neurons Correct Answer-send information from the brain and
spinal cord (CNS) to the muscles
Three main parts of neurons Correct Answer-Cell body, Axon, and
Dendritic Tree
Cell body Correct Answer-Contains the nucleus and other cellular
machinery necessary for cell functioning
Axon Correct Answer-Carries information from the cell body to the
synapse
,Dendritic Tree Correct Answer-receives input from the other cells or
neurons
Glia or Glial Cells Correct Answer-Serve as "support cells" and do not
convey info like neurons, but do have many functions
4 main functions of Glia Correct Answer-1. They can modify
environment for neurons
2. They can remove dead neurons
3. Some Glial cells myelinate axons
4. Some Glial cells help maintain the blood/brain barrier
Gray matter Correct Answer-Is made of Neuronal cell bodies (pink part
of the brain)
White matter Correct Answer-Lots of myelination from glial cells; areas
of the brain that are connecting neurons to other neurons (whitish part)
Central Nervous system Correct Answer-brain and spinal cord
Peripheral Nervous system Correct Answer-All neural tissue beyond the
central nervous system. Neurons that relay information to and from CNS
Anterior Correct Answer-The front of the brain
,Posterior Correct Answer-Back of the brain
Superior Correct Answer-Top of the brain
Inferior Correct Answer-Bottom of the brain
Rostral Correct Answer-Towards the front/head
Caudal Correct Answer-Towards the back/tail
Dorsal Correct Answer-Above and towards the back
Ventral Correct Answer-Below towards the belly
Proximal Correct Answer-Means near when referring to the body
midline
Distal Correct Answer-Means far when referring to the body midline
Bilateral Correct Answer-both sides of the brain
Unilateral Correct Answer-one side of the brain
, Ipsilateral Correct Answer-Means same side of the brain
ontralateral Correct Answer-means opposite side of the brain
Coronal way of cutting the brain Correct Answer-Brain is separated
from top to bottom (ear muff orientation)
Horizontal or Axial Correct Answer-Separated from front to back (sweat
band orientation)
Sagittal Correct Answer-Brain is separated from left to right
Medial or midsagittal Correct Answer-Middle of the brain
Ventricles Correct Answer-fluid filled spaces in the brain that contain
cerebrospinal fluid that cushions the brain
Lateral ventricles Correct Answer-Most prominent. Left and right are
separated by tissue
Third Ventricle Correct Answer-situated at the midline between right
and left thalamus
