Unit 2 Flashcards
The meningeal layer that adheres to the surface of the brain is called
pia mater
The number of cranial bones is:
8
White brain matter
is composed of neurons with myelinated axons
The the fissure separating the frontal and parietal lobes from the temporal lobe is the
lateral
The fissure separating the occipital lobe/cerebrum from the cerebellum is the
transverse
The large section of white matter connecting the two cerebral hemispheres is the
corpus callosum
Where would you find diploe?
in between layers of compact bone in the skull
The neurons bringing in sensory information to he central nervous system are:
afferent neurons
Cerebrospinal fluid is found in the
ventricles of the brain
cisterns of the brain
the central canal of the spinal cord
all of the above
Which ventricle sits anterior to the cerebellum?
fourth
The vertebral arteries join together to for the
basilar artery
Which cranial bone is one of a pair?
parietal
The foramen magnum is associated with which cranial bone?
occipital
The meningeal layer in contact with the cranium is the
dura mater
The shallow grooves on the surface of the brain are
sulci
The roof of the orbit is formed by the
frontal bone.
Which facial bone is not one of a pair?
None of the above; they are all pairs
What vessels are responsible for drainage of the head?
Dural sinuses
Which of the following sutures separates the temporal and parietal bones?
squamous
Which of the following sutures separates the parietal and occipital bones
lambdoidal
What mechanism is in place for protecting the brain by preventing certain substances from crossing over?
Blood brain barrier
The ventricles provide a pathway for what substance within the brain?
CSF
The epithalamus, thalamus, metathalamus and hypothalamus are all considered the
diencephalon
The pons, medulla oblongata cerebellum and pineal gland are all considered the
Hindbrain
The area of the brain responsible for manufacturing CSF is the
choroid plexus
Which gland is the master gland?
pituitary gland
What structures are responsible for transferring CSF into the Dural sinuses and Dural venous sinus?
arachnoid villi
