Correct.
This is the most superficial layer of the brain meninges
Dura Mater (Menix)
This layer of the meninges is tightly attached to the brain.
Pia mater (Menix)
The _______ fissure separates the right and left cerebral hemispheres.
median
The ______ fissure separates the cerebrum from the cerebellum.
Transverse
Describe the function of the brain ventricles.
There are four ventricles in the interior of the brain, chambers filled with cerebrospinal fluid
which is produced there. Once formed the CSF circulates through the ventricles and into the
subarachnoid space bathing and floating the brain.
What is the purpose of the blood-brain barrier? Describe its maintenance from a cellular
level.
The blood-brain barrier is a diffusion barrier which prevents most particles from entering the
central nervous system tissue, keeping the brain and spinal cord separate from general blood
circulation. The blood-brain barrier is formed by the relatively impermeable brain capillaries,
, due to the glial cells astrocytes. Maintenance of the blood-brain-barrier is important to provide a
stable chemical environment for the nervous system.
All the following are functions of the hypothalamus except:
Relays sensory impulses to the cerebrum
This ventricle is located anterior to the cerebellum.
fourth
What is the largest portion of the brain?
Cerebrum
This region of the brain acts to coordinate multiple sources of sensory information.
Association area
This region of the brain controls decision making skills
Frontal lobe
A patient is having difficulty understanding language but is sill able to speak fluently. The
patient's dermatomes are intact. Which area of the brain is most likely damaged?
Wernicke'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
