Which term refers t/t inability to recognize objects thru a particular sensory system agnosia aphasia ataxia dementia
answer 1 Agnosia may be visual, auditory, or tactile. Dementia refers to organic loss of intellectual function. Ataxia refers t/t inability to coordinate muscle movements. aphasia refers to loss o/t ability to express oneself or to understand language.
Which neurotransmitter demonstrates inhibitory action, helps control mood n sleep, n inhibits pain pathways? serotonin norepinephrine acetylcholine enkephalin
answer 1 the brain stem, hypothalamus, and dorsal horn o/t spinal cord are sources of serotonin. Enkephalin is excitatory and associated w/pleasurable sensation. Norepinephrine is usually excitatory n affects mood n overall activity. Acetylcholine is usually excitatory, but the parasympathetic effects are sometimes inhibitory.
which cranial nerve is responsible for muscles that move the eye n lids? oculomotor trigeminal vestibulocochlear facial
answer 1 the oculomotor (3) cranial nerve is also responsible for pupillary constriction n lens accommodation. The trigeminal (V) cranial nerve is responsible for facial sensation, corneal reflex, and mastication. the vestibulocochlear (8) cranial nerve is responsible for hearing n equilibrium. The facial (7) nerve is responsible for salivation, tearing, taste, n sensation i/t ear.
upper motor lesions cause? a little to no muscle atrophy flaccid paralysis absent or decreased reflexes decreased muscle tone
answer 1 upper motor lesions cause little to no muscle atrophy but do cause loss of voluntary control. Lower motor neuron lesions cause decreased muscle tone, flaccidity, and absent or decreased reflexes.
Which term describes the fibrous connective tissues that cover the brain n spinal cord? dura mater pia mater meninges arachnoid mater
answer 3 the meninges have 3 layers: the dura mater, arachnoid mater, n pia mater. The dura mater is the outermost layer o/t protective layer o/t brain n spinal cord. the arachnoid is them middle membrane and pia mater is the innermost.
Which cerebral lobe contains the auditory receptive areas? occipital frontal temporal parietal
answer 3 the temporal lobe plays the most dominant role of any area o/t cortex in cerebration. the frontal lobe, the largest lobe controls concentration, abstract thought, information storage or memory, n motor function. the parietal lobe contains the primary sensory cortex, which analyses sensory information n relays interpretation t/t thalamus n other cortical areas. the occipital lobe is responsible for visual interpretation.
Which cranial nerve is responsible for facial sensation n corneal reflex? vestibulocochlear oculomotor facial trigeminal
answer 4 The trigeminal (V) cranial nerve is also responsible for mastication. the oculomotor (3) cranial nerve is responsible for the muscles that move the eye and lid, pupillary constriction, and lens accommodation. the vestibulocochlear (7) cranial nerve is responsible for hearing and equilibrium. the facial nerve is responsible for salivation, tearing, taste, and sensation i/t ear.
which cerebral lobe is the largest n controls abstract thought? occipital temporal parietal frontal
answer d the frontal lobe also controls information storage or memory n motor function. The temporal lobe contains the auditory receptive area. The parietl lobe contains the primary sensory cortex, which analyses sensory information n relays interpretation t/t thalamus n other cortical areas. the occipital lobe is responsible for visual interpretation.
