chapter 17 Flashcards
brain
which one of the meninges is just superficial to the surface of the brain
pia mater
what fluid is found in the ventricles of the brain
cerebrospinal fluid
into what space does fluid flow from the cerebral aqueduct
third to fourth ventricle
what is the difference between a gyrus and a suclus
gyrus-ridges of the convolutions
suclus- depressions of the convolutions
name all the lobes of the cerebrum
frontal lobe, parietal lobe, occipital lobe, and temporal lobe
what is the function of the precentral gyrus
this cortex is important for directing a part of the body to move and has been mapped
what sense foes the temporal lobe alone interpret
hearing
what physical depression separates the temporal love from the parietal lobe
lateral fissure
what structure connects the cerebral hemispheres
longitudinal fissure
name the major regions of the midbrain
cerebral peduncles, cerebral aqueduct, tectum corpora, quadrigemia, superior colliculi, inferior colliculi, substantia nigra
what is the function of the cerebellum
is a location primarily noted for muscle coordination and maintenance of posture
John ‘pulled a no-brainer’ by hitting his forehead against a wall. What damages might he have done to the functioning of his brain, particularly the functions associated with the frontal lobe
he could affect anything involving intellect, abstract reasoning, creativity, social awareness, and language
If a stroke had affected all the sensations interpreted by the brain concerning only the face and the hands, how much of the post-central gyrus would be affected
at least d/3 affected
describe what effect a loss of an entire cerebral hemisphere would have on specific functions, such as spatial awareness or the ability to speak
spatial awareness would decrease and would cause a loss of speech
aphasia is loss of speech. different types of aphasia can occur. if the Broca area were affected by a stroke, would the content of the spoken word be affected, or would the ability to pronounce the words be affected
ability to pronounce
optic nerve (sensory, motor, or both)
sensory
trochlear nerve (sensory, motor, or both)
motor
glossopharyngeal nerve (sensory, motor, or both)
both
hypoglossal nerve (sensory, motor, or both)
motor
vagus nerve (sensory, motor, or both)
both
