A&P DSM chapter 14 sections 14.1-14.3
which of the following statements about a subdural hemorrhage is true?
a break in a vein may cause blood to flow to the meningeal layer of the dura mater down to the arachnoid
neural tissue in the central nervous system (CNS) is isolated from the general circulation by the
blood-brain barrier
monitoring the composition of the cerebrospinal fluid (CSF) and the removal of waste products from the CSF occurs in the:
choroid plexus
excess cerebrospinal fluid is returned to the venous circulation by:
diffusion across the arachnoid villi
a buildup of cerebrospinal fluid (CSF) in the cranial cavity can lead to:
enlargement of the cranium in infants, compression of brain tissue and impairment of neural function, and "water on the brain" or hydrocephaly
what are the structures in the cerebrum that are elevated ridges, which increase surface area to increase the number of neurons in a specific area?
gyri
what would happen if the normal circulation of resorption of cerebrospinal fluid (CSF) were blocked?
hydrocephalus
fresh blood, with oxygen and nutrients, reaches the brain through the:
internal carotid and verbal arteries
fresh blood, with oxygen and nutrients, reaches the brain through the
internal carotid and vertebral arteries
why is damage to the medulla potentially so harmful despite the fact that the medulla is the lowest part of the brainstem?
it contains vital autonomic reflex centers
the cardiovascular centers and the respiratory rhythmicity centers are located in the
medulla oblongata
the cardiovascular centers and the respiratory rhythmicity centers are located in the:
medulla oblongata
which part of the brainstem has a control center that sets the basic pace or rhythm of breathing?
medulla oblongata
what is the sequence of the structures that make up the brainstem going from the diencephalon to the spinal cord?
midbrain, pons, medulla
which of the meninges adheres to the surface of the brain and accompanies the branches of the blood vessels as they penetrate the surface of the brain?
pia mater
the blood-brain barrier remains enact throughout the central nervous system EXCEPT in
portions of the hypothalamus and the choroid plexus
which of the following is NOT a function of cerebrospinal fluid?
providing the blood-brain barrier
which of the following is NOT a function of the cerebrospinal fluid?
providing the blood-brain barrier
which of the following is NOT a function of the medulla oblongata?
receiving and interpreting visual stimuli
which of the following is NOT part of the brain stem?
thalamus
which of the meningeal membranes creates a space outside the brain where cerebrospinal fluid circulates?
the arachnoid mater
which of the following provides mechanical protection for the brain by cradling it?
the bones of the skull
which of the following structures does NOT provide protection and shock absorption for the brain?
the carotid arteries and jugular veins
what are the structures in the medulla that relay sensory information to the the thalamus?
the gracile nucleus and the cuneate nucleus
what are two structures that integrate the functioning of the nervous system and endocrine system?
the hypothalamus and pituitary gland
what are two structures that integrate the functioning of the nervous system and the endocrine system?
the hypothalamus and the pituitary gland
the versatility of the brain to respond to stimuli is greater than that of the spinal cord because of:
the number of neurons and the complex interconnections among the neurons
what are the two parts of the brain that compose the diencephalon?
the thalamus and the hypothalamus
which of the following is NOT a function of cerebrospinal fluid?
transporting oxygen to brain cells
which of the following is NOT a function of cerebrospinal fluid?
transporting oxygen to the brain cells.
