Anat And Physiology For Speech Language And Hearing Ch12

Front 1

action potential

Back 1

is a change in electrical potential that occurs when a cell membrane is stimulated adequately to permit ion exchange between the intra and extracellular spaces

Front 2

absolute refractory period

Back 2

is the time during which the cell membrane cannot be stimulated to depolarize

Front 3

relative refractory period

Back 3

is a period during which the membrane may be stimulated to excitation again but only with greater than typical stimulation

Front 4

nodes of ranvier

Back 4

of the axon myelin promote saltatory conduction

Front 5

neurotransmitter

Back 5

is discharged into the synaptic cleft stimulating the postsynaptic neuron.

Front 6

THICK

Back 6

activation of a muscle fiber cause the release of calcium in to the environment of what myofilaments

Front 7

_______ twitch muscle fibers remain contracted longer than _____ twitch fibers

Back 7

slow, fast

Front 8

Muscle Spindles

Back 8

provide feedback to the neuromotor system about muscle length, tension, motion, and position.

Front 9

Association

Back 9

higher cognitive processing occurs generally in _________ areas.

Front 10

tempro-occipital-parietal association

Back 10

area is involved in language function

Front 11

Flaccid

Back 11

dysarthria results from damage to LMN's whereas UMN Lesions result in spastic dysarthria

Front 12

hyperkinetic

Back 12

dysarthria is the result of damage to the inhibitory processes of the extrapyramidal systems

Front 13

prefrontal

Back 13

area of the cerebrum appears to be involved in higher function related to motor output such as inhibition of motor function and the ability to change motor responses , whereas the Top association area is involved in language function

Front 14

limbic association

Back 14

area integrates information related to affect, motivation, and emotion

Front 15

Left hemisphere

Back 15

in most individuals is dominant for language and speech, processes, brief duration stimuli, and performs detailed analysis

Front 16

right hemisphere

Back 16

appears to process information in a more holistic fashion, preferring spatial and tonal information

Front 17

wernicke's

Back 17

damage to this area in the dominant hemisphere usually results in a receptive language deficit with relatively intact speech fluency

Front 18

Broca's

Back 18

damage to this area in the dominant hemisphere often results in loss of speech fluency manifested as Broca's aphasia

Front 19

arcuate

Back 19

damage to this fasciculus will result in conduction aphasia

Front 20

VII Facial Nerve

Back 20

Quite important for speech.it inner area the facial muscles of expression and tear glands.It also mediates the sense of taste for a portion of the tongue. This nerve supplies all of the facial muscles

Front 21

V trigeminal nerve

Back 21

This nerve is an extremely important mixed nerve for speech production. This means it has both sensory and motor components. This nerve provides motor inner action to the muscles of mastication it also transmits sensory info from the face.

Front 22

V trigeminal nerve

Back 22

This nerve is an extremely important mixed nerve for speech production. This means it has both sensory and motor components. This nerve provides motor inner action to the muscles of mastication it also transmits sensory info from the face.

Front 23

The v trigeminal divides into 3 parts why are they

Back 23

Ophthalmic branch, maxillary branch, mandibular branch

Front 24

Ophthalmic nerve

Back 24

Is entirely sensory. It transmits general sensory info from the skin to upper face forehead scalp cornea iris upper eyelid

Front 25

Ophthalmic nerve

Back 25

Is entirely sensory. It transmits general sensory info from the skin to upper face forehead scalp cornea iris upper eyelid

Front 26

Maxillary nerve

Back 26

Is sensory. It transmits info from lower eyelid skin on side of nose upper jaw teeth lip nasal cavities sinuses

Front 27

Ophthalmic nerve

Back 27

Is entirely sensory. It transmits general sensory info from the skin to upper face forehead scalp cornea iris upper eyelid

Front 28

Maxillary nerve

Back 28

Is sensory. It transmits info from lower eyelid skin on side of nose upper jaw teeth lip nasal cavities sinuses

Front 29

Mandibular nerve

Back 29

Is mixed it has afterwork and efferent parts
