Q

Usually not aware of these reflexes
They activate smooth muscles, cardiac muscles, and glands of the body and they regulate body functions(ie/digestion, elimination blood pressure, salivation and sweating)

Q

absence of this reflex indicates damage to the brain stem

A

corneal reflex

19
Q

this tests the somatic motor responses of cranial nerves IX and X

A

gag reflex

20
Q

any reflex observed on one side of the body when the other side has been stimulated

A

contralateral response

21
Q

any reflex occurring on the same side stimulated

A

ipsilateral response

22
Q

what should happen during the ciliospinal reflex?

A

pupil dialation

23
Q

what are the effectors of the salivary reflex

A

glands

24
Q

7 reflexes classified as somatic reflexes

A

abdominal reflex, calcaneal tendon reflex, corneal reflex, crossed extensor reflex, gag reflex, plantar reflex, and patellar reflex

25
Q

the two stretch reflexes

A

calcaneal tendon reflex and patellar reflex

26
Q

the two superficial cord reflexes

A

plantar reflex and abdominal reflex

27
Q

two spinal cord mediated reflexes

A

patellar and cross extensor

28
Q

react to stimuli

A

sensory receptors

29
Q

react to touch, pressure, pain heat, cold, stretch, vibration etc

A

general sensory receptors

30
Q

vision, hearing, equilibrium, smell, taste

A

special senses

31
Q

how are sensory receptors classified

A

type of stimulus, structure, body location

32
Q

react to stimuli in the external environment

A

exteroceptors

33
Q

respond to stimuli arising within the body

A

interoceptors

34
Q

respond to internal stimuli but are restricted to skeletal muscles, tendons, joints, ligaments, and connective tissue; they provide info about body movements and position by monitoring the degree of stretch

A

proprioceptors

35
Q

cutaneous receptors and proprioceptors

A

general sensory receptors

36
Q

Least specialized of the cutaneous receptors that respond to pain and temperature

A

nonencapsulated nerve endings(free)

37
Q

free nerve endings that associate with specific epidermal cells form _________ ______

A

tactile(Merkel) discs

38
Q

free nerve endings that entwine in hair follicles form _____ _______

A

hair follicle receptors

39
Q

consists of the lacrimal gland, lacrimal canaliculi, lacrimal sac, and nasolacrimal duct

A

lacrimal apparatus

40
Q

situated superior to the lateral aspect of each eye

A

lacrimal glands

41
Q

tears flush across eyeball through this

A

lacrimal puncta

42
Q

this empties into the nasal cavity

A

nasolacrimal duct

43
Q

antibacterial enzyme

A

lysozyme
