Neuro test 2

An increased pain response to nociceptive stimulus

Hyperalgesia

I put on my watch and feel it initially, but then I do not feel it or notice it through out the day because of:

Phasic receptors

the parasympathetic nervous system is responsible for:

rest and digest

brain initiated central sensitization syndrome characterized by hypothalamus dysfunction

Migraine

The primary system of this disease is widespread pain that does not follow a nerve pattern; abnormal pain processing

fibromyalgia

A movement disorder caused by abnormal brain development or permanent, non progressive damage to the developing brain

cerebral palsy

Brief loss of consciousness due to inadequate blood flow to the brain

syncope

when do neurons differentiate into their final function?

after they reach their final destination

Romberg test: Decrease in balance only when eyes are closed means:

sensory dysfunction

Fertilization of the ovum occurs in the:

uterine tube

conscious relay pathway vs. divergent relay pathway (written)

conscious: convey high accuracy, somatotypical info to cerebral cortex. Divergent: convey info not somatotypical to many parts of brain.

when neurons cross from one side to the other (written)

decussate

primary somatosensory cortex anatomically located (written)

gyrus posterior to central sulcus (postcentral gyrus)

structures referred pain arise from (written)

visceral structures

antinociception vs. pronociception (written)

antinociception: supresion of nociception in response to normally painful stimuli. Pronociception: produces pain in absence of nociceptive input

neurological problems appear as child reaches an age of normal developmental milestones

growing into deficit

main mechanism underlying chronic pain

central sensitization

identify object through touch with eyes closed

sterognosis

facial sensation

trigeminal

dermis innervated by single spinal nerve

dermatome

muscle innervated by single spinal nerve

myotome

tingling or prickling sensation

parasthesia

figure representing parts of body controlled or transmitting sensory info to specific parts of cerebral cortex

homonculus

responds to tension in a tendon

golgi tendon organ

small diameter sensory fibers

C

large diameter sensory fibers

la

motor nerves

efferent

sensory nerves

afferent

free nerve endings mediate all of the following except

fine touch

longitudinal thickening of ectoderm in embryonic stage

neural plate

all unconscious relay tracks end here

cerebellum

myelination of axons begins

fetal stage

all of the following determines how quickly info from periphery to brain is preocessed except:

the amount of neurotransmitter released

spinal nerve inservating lateral side of forearm into thumb and index finger

C6

hemisection (brown-sequard’s syndrome) of spinal cord would cause

contralateral loss of pain and temp and ipsilateral loss of discriminitive touch and proprioception

contralateral loss of pain and temp and ipsilateral loss of discriminative touch and proprioception

brown-sequard’s syndrome

Allen is is not smiling or showing interest in opening Christmas presents. He is not interacting with family members. He is showing signs of:

autism spectrum disorder

George has issues in school. he falls out of his chair and is always tapping his pencil on his desk. He loses focus quickly and has issues following instructions because of that. George would benefit from this class of medication

stimulant

Lucy pet a cat with her right hand. This info traveled up what track until it reached her medulla?

fasciculus cuneatus

Nancy experiences extreme pain when anything, even clothes, touch her hand. The hand is also swollen and blotchy. Nancy is experiencing:

allodynia

sharp, discrimative pain travels up what pathway?

lateral pain system

Kaylee saw the man of her dreams and suddenly, her heart started beating faster, she began to sweat and the hairs on her arms were standing on end. This reaction is due to input from:

sympathetic nervous system

Jerry was swimming when a slimy fish brushed up against his right leg. Which side of Jerrys brain percieved the fish?

left

the 3rd neuron in the conscious relay pathway that discriminates temperature begins in what structure?

thalamus

Mrs. Jackson had her blood pressure taken in supine. It was 128/80. After Mrs. Jackson stood up, she began to feel light headed. When the PTA took her blood pressure again, it dropped to 102/67. The PTA should document that the pt, demonstrated:

orthostatic hypotension

layer the nervous system comes from

ectoderm

A pt. is taking a Romberg test and cannot keep their balance, even with their eyes open. These symptoms are likely caused by:

cerebellar dysfunction

where the dermis and skeleton com from

mesoderm

unconscious sensory info that helps us make minor adjustments terminates in this part of the brain

cerebellum

sensory organ in muscle primarily sensitive to passive strtech

muscle spindle

mechanoreceptors respond to all except:

pain

neural tube defects include all except

cerebral palsy

pin prick tests for:

pain

the CNS is most susceptable to malformations btw day ___ and day ____.

14/140

the main function of thalamus

sensory integration

the pre embryonic stage

0-2 weeks

where the primary somatosensory region of the brain is

postcentral gyrus

development of the brain starts on day:

28

in the adult, the spinal cord ends at what vertebral level?

L1-L2

myelination is complete by:

the third year of life

nociceptors respond to this

damage or threatened tissue damage

discromitive touch and conscious proprioceptive info from the leg ascends the spinal cord in the

fasciculus gracilis

the neural tube form in this direction

from cervical area down

where the perception of sensation occurs

cerebral cortex

why the spinal cord ends before the end of the vertebral column

from the 3rd month on, the vertebra will grow faster

where touch receptors are most sensitive

finger tips
