BIOD 152 MODULE 2 UPDATED QUESTION AND
ANSWERS 2024/2025
Dura mater
This is the most superficial layer of the brain meninges.
Pia Mater
This layer of the meninges is tightly attached to the brain.
Transverse
The ________ fissure separates the cerebrum from the cerebellum.
Median longitudinal
The ________ fissure separates the right and left cerebral hemispheres.
It is a diffusion barrier. It keeps brain and spinal cord separate from general blood
circulation.
BBB is crucial for stable chemical environment NS. Formed from astrocytes
surrounding brain capillaries.
What is the purpose of the blood-brain barrier? Describe its maintenance from a cellular
level
The 4 brain ventricles (two lateral, one third, one fourth) are located inside the
brain and produce and store CSF - drains into the central canal of the spinal cord
Describe the function of the brain ventricles.
Relays sensory impulses to the cerebrum
All the following are functions of the hypothalamus except:
-Maintain homeostasis
-Controls the pituitary gland
-Links the nervous and endocrine systems
-Relays sensory impulses to the cerebrum
Filters out unimportant sensory information
All of the following are functions of the hypothalamus except:
-Regulates sleep
-Links the nervous and endocrine system
-Filters out unimportant sensory information
-Regulates water balance
Cerebrum
What is the largest portion of the brain?
-Cerebellum
-Cerebrum
-Corpus collosum
-Cingulate gyrus
Fourth
This ventricle is located anterior to the cerebellum.
-Lateral
, -Medial
-Third
-Fourth
Frontal lobe
This region of the brain controls decision making skills.
-Frontal lobe
-Cerebellum
-Occipital lobe
-Temporal lobe
-Primary sensory cortex
Association area
This region of the brain acts to coordinate multiple sources of sensory information.
-Primary sensory cortex
-Primary motor cortex
-Association area
-Precentral gyrus
-Postcentral gyrus
Wernicke's area
A patient is having difficulty understanding language but is still able to speak fluently.
The patient's dermatomes are intact. Which area of the brain is most likely damaged?
-Broca's area
-Wernicke's area
-Occipital lobe
-Parietal lobe
-Primary sensory cortex
Broca's area
A patient is having difficulty producing speech sounds, but other motor movements are
normal. Which area of the brain is most likely damaged?
-Broca's area
-Wernicke's area
-Occipital lobe
-Parietal lobe
-Primary motor cortex
This occurs throughout the cerebral hemisphere. Memory storage/retrieval are
carried out by the hippocampus and other related structures in the temporal lobe.
Describe how memories are stored and retrieved in the brain. Include a specific brain
region.
Level of partial contraction that muscles maintain even when at rest. Maintained
and regulated by the cerebellum to stabilize bones and joints.
What is muscle tone and how is it maintained?
The midbrain helps to regulate breathing
