Portage Learning Anatomy and Physiology II Module 2 Nervous
System Examination (A&P II M2 NS) Exam Questions and
Answers
Brain - 4 Divisions - ANSWER>>cerebrum, brainstem, diencephalon, cerebellum
Ventricles - ANSWER>>cavities within the brain that are filled with cerebrospinal
fluid
Meninges - ANSWER>>three layers of connective tissue membranes that cover
and protect central nervous system organs and enclose cerebrospinal fluid.
Dura Matter (Meninges) - ANSWER>>the double-layered outer meninx
leathery
Arachnoid meninx (Meninges) - ANSWER>>a loose layer separated from the dura
mater by the subdural space
Middle
Pia mater (meninges) - ANSWER>>a thin connective tissue tightly attached to the
brain
Blood Brain Barrier (BBB) - ANSWER>>a diffusion barrier that prevents most
particles from entering the central nervous system tissue, keeping the brain and
spinal cord separate from general blood circulation
Cerebrum - ANSWER>>the foremost part of the brain, is the largest part of the
brain in humans comprising about 83% of total brain mass. It consists of two large
masses called the left and right cerebral hemispheres
,median longitudinal fissure - ANSWER>>separates left and right cerebral
hemispheres
Gyri (gyrus) - ANSWER>>raised ridges of the cerebral cortex
Sulci - ANSWER>>shallow grooves that separate gyri
corpus callosum - ANSWER>>a bridge of white nerve fibers that connects the
cerebral hemispheres
cerebral cortex - ANSWER>>the outer portion of the cerebral hemispheres
highly convoluted and gray in color
frontal lobe - ANSWER>>controls higher level executive functions, such as
reasoning and decision making.
Controls motor functions and permits control over voluntary muscle actions.
parietal lobe - ANSWER>>receives sensory information from receptors in the
mouth for taste and located in the skin, such as those for touch, pressure, and
pain
occipital lobe - ANSWER>>visual processing
temporal lobe - ANSWER>>lobe that has sensory areas for hearing and smelling
primary areas - ANSWER>>receives or sends information for one type of sensory
or motor information
areas of the cortex involved in sensory functions and in the direct control of
motor movements
association areas - ANSWER>>act mainly to integrate more than one type of
sensory information for purposeful action
, receives information from the other lobes and integrates it into higher, more
complex levels of consciousness. Some examples of higher levels of consciousness
are intellect, artistic/creative ability, learning, and memory
primary motor cortex - ANSWER>>the section of the frontal lobe responsible for
voluntary movement for all parts of the body
primary sensory cortex - ANSWER>>regions of the cerebral cortex that initially
process information from the senses
Broca's area - ANSWER>>speech production
located in the frontal lobe
Wernicke's area - ANSWER>>language comprehension
located in the temporal lobe
Brainstem - ANSWER>>responsible for automatic survival functions
medulla oblongata - ANSWER>>Part of the brainstem that controls vital life-
sustaining functions such as heartbeat, breathing, blood pressure, and digestion.
lies between the spinal cord and pons and is anterior to the cerebellum
Pons - ANSWER>>contains bundles of axons traveling between the cerebellum
and the rest of the CNS
functions with the medulla to regulate the breathing rate and has reflex centers
concerned with head movements in response to visual and auditory stimuli
Midbrain - ANSWER>>acts as a relay station for tracts passing between the
cerebrum and spinal cord or cerebellum
has reflex centers for higher level reflexes involving visual, auditory and tactile
responses
Diencephalon - 3 parts - ANSWER>>thalamus, hypothalamus, epithalamus
