Bio 201 Lab Exam #4 UPDATED ACTUAL
Exam Questions and CORRECT Answers
longitudinal fissure - CORRECT ANSWER - long deep groove that separates left and
right cerebral hemispheres
4: temporal lobes - CORRECT ANSWER - form lateral surface of each cerebral
hemisphere, separated from parietal and frontal lobes by lateral fissure, Neurons in these lobs are
involved in hearing, language, memory, and emotions
insulas - CORRECT ANSWER - deep underneath lateral fissures; neurons in these lobes
are currently thought to be involved in functions related to taste and viscera (internal organs)
1: frontal lobes - CORRECT ANSWER - most anterior lobes, responsible for planning and
executing movement and complex mental functions such as behavior, conscience, and
personality
5: central sulcus - CORRECT ANSWER - shallow grove that is the posterior border of the
frontal lobe
3: occipital lobes - CORRECT ANSWER - makes up posterior aspect of each cerebral
hemisphere, separated from parietal lobe by parieto-occipital sulcus, neurons in these lobes
process all information related to vision
6: precentral gyrus - CORRECT ANSWER - contains the primary motor cortex
2: parietal lobes - CORRECT ANSWER - just posterior to frontal lobes, responsible for
processing and integrating sensory information and function in attention
7: postcentral gyrus - CORRECT ANSWER - contains the primary somatosensory cortex
, 35: cerebellum - CORRECT ANSWER - makes up posterior and inferior portion of brain:
functionally connected with cerebral cortex, basal nuclei, brainstem, and spinal cord; interactions
between these regions together coordinate movement
36: pons - CORRECT ANSWER - inferior to midbrain; regulates movement, breathing,
reflexes, and complex; functions associated with sleep and arousal
10: corpus callosum - CORRECT ANSWER - the largest commissural fibers that connects
the right and left hemispheres
12: fornix - CORRECT ANSWER - c-shaped ring of white matter; main output tract
39: medulla oblongata - CORRECT ANSWER - most inferior structure of brainstem;
continuous with spinal cord at foramen magnum
19: thalamus - CORRECT ANSWER - main entry route of sensory data into cerebral
cortex; relay station that receives input, integrate information, then sends information to specific
motor or sensory areas in the cerebral cortex
26: choroid plexus - CORRECT ANSWER - where majority of CSF is manufactured;
found in each of four ventricles where blood vessels come into direct contact with ependymal
cells (also produces some CSF themselves)
21: hypothalamus - CORRECT ANSWER - collection of nuclei anterior and inferior to
larger thalamus; regulates the autonomic nervous system, sleep/wake cycle, thirst, and hunger,
and body temperature
35D: arbor vitae - CORRECT ANSWER - cerebellar cortex is extremely folded and has
branching white matter that resembles tree branches
11: lateral ventricle - CORRECT ANSWER - cavity that is continuous with central canal
of spinal cord; lined with ependymal cells; filled with cerebrospinal fluid
