COMD 4500 FINAL Exam Questions And Cor
Which professionals can make a medical diagnosis? - CORRECT ANS✔✔Medical professionals (d
Excitatory inputs to a neuron - CORRECT ANS✔✔brings target neuron closer to threshold
inhibitory inputs to a neuron - CORRECT ANS✔✔takes target neuron further from threshold
frontal - CORRECT ANS✔✔BRAIN LOBES AND FUNCTIONS
voluntary movement, cognition; control panel for personality and emotions; problem solving, judgme
formulation
occipital - CORRECT ANS✔✔BRAIN LOBES AND FUNCTIONS
vision; signals from the optic nerve will end up here, so that they can be further processed into unde
visual world around us
temporal - CORRECT ANS✔✔BRAIN LOBES AND FUNCTIONS
hearing & memory processes; sense of hearing and processing sensory input. Not only does this re
presence of sound, but of course it helps us understand those sounds
parietal - CORRECT ANS✔✔BRAIN LOBES AND FUNCTIONS
sense of taste, touch, sensation of movement and where the body is in space
CNS - CORRECT ANS✔✔BASIC NEURAL STRUCTURES
brain and spinal cord-protected by meninges-cerebrospinal fluid-blood brain barrier
Two main structures: the brain & spinal cord
gray matter for processing signals taking place within the brain
, some sensory and motor - e.g., facial VII, it controls the muscles of facial expression and also conv
brain from the taste buds on the front two thirds of the tongue
some motor only - e.g., hypoglossal; responsible for almost all of the muscles of the tongue
Cranial Nerves - CORRECT ANS✔✔•12 pairs
•some sensory only - e.g., olfactory
•some sensory and motor - e.g., facial
•some motor only - e.g., hypoglossal
originate in brain stem and serve functions for sensation and motor control for head and neck
12 pairs
some sensory only - e.g., olfactory, optic
some sensory and motor - e.g., facial VII, it controls the muscles of facial expression and also conv
brain from the taste buds on the front two thirds of the tongue
some motor only - e.g., hypoglossal; responsible for almost all of the muscles of the tongue
Peripheral Nervous System (PNS) - CORRECT ANS✔✔•sensory input from the periphery
•motor output to muscles
•spinal nerves for trunk and limbs
•cranial nerves for head and neck
descending motor tracts - CORRECT ANS✔✔carry motor instructions from the brain to the body's m
direct pathways - CORRECT ANS✔✔•a.k.a. pyramidal system
•corticobulbar tract
•leads to cranial nerves
•head and neck muscles
•controls larynx and articulators
•corticospinal tract
•leads to spinal nerves
•limb control
•trunk muscles
indirect pathways - CORRECT ANS✔✔•cerebellum
•motor learning
•compares motor commands with results
•error correction
•basal ganglia
•sequencing of complex movements
•integration of sensory signals
•coordination
NEUROIMAGING (what each show)
x-ray imaging - CORRECT ANS✔✔-broad x-rays passed through tissue (to sensor or film)-energy i
absorbs more, lighter in color)-2D view of 3D object (no dimensionality)
x-rays details - CORRECT ANS✔✔depend on tissue density differences to show structure, cannot
fractures, bone erosion, calcification, widely available, inexpensive, excellent spatial resolution
Cerebral angiography (arteriography) - CORRECT ANS✔✔§uses x-ray images
§catheter into right femoral artery
§passed via aorta to carotid
§radio-opaque dye injected
§frontal and lateral views
