Q

Hair Receptors

A

~bare dendrites with no associated connective tissue
~wrapped around the base of a hair follicle
~mechanoreceptors for any light touch that bends a hair

20
Q

Lamellar Corpuscles

A

~single dendrites surrounded by flattened Schwann cells that in turn are surrounded by fibroblasts, giving a layered appearance like tree rings
~deep in the dermis, especially on the hands, breasts, and genitals
~mechanoreceptors for deep pressure, stretch, and vibration

21
Q

Bulbous (Ruffini) Corpuscles

A

~long, flattened capsules with a few nerve fibers
~dermis if the skin
~mechanoreceptors for heavy touch, pressure, and stretching of the skin

22
Q

Tactile Disks

A

~flattened nerve endings
~stratum basale of the epidermis next to specialized tactile cells
~mechanoreceptors for light touch

23
Q

Gustation

A

the sense of taste

24
Q

Pinna

A

external ear flap composed of elastic cartilage

25
Q

Auditory Canal

A

leads from opening in temporal bone to the tympanic membrane

26
Q

External Auditory Meatus

A

opening in the temporal bone

27
Q

Tympanic Membrane

A

eardrum

28
Q

Malleus

A

attached to tympanic membrane and forms a synovial joint with the incus

29
Q

Incus

A

forms synovial joint with the stapes

30
Q

Stapes

A

comes into contact with a membranous oval window located at the beginning of the inner ear

31
Q

Ossicles

A

malleus, incus, stapes

32
Q

Cochlea

A

snail-like fluid-filled coil embedded in the bony labyrinth

33
Q

Static Equilibrium

A

equilibrium perceived when the head is stationary or moving in a straight line

34
Q

Dynamic Equilibrium

A

equilibrium perceived when the head is rotating

35
Q

Vestibular Apparatus

A

anatomy used to perceive equilibrium; includes the saccule. utricle, and semicircular canals of the inner ear

36
Q

Otoliths

A

calcium carbonate and protein granules located in the saccule and utricle of the inner ear

37
Q

Refraction

A

the bending of light as it passes through materials of different densities

38
Q

Glaucoma

A

a condition characterized by increased intraocular pressure, diagnosed with tonometer, can be stopped but damage cannot be reversed

39
Q

Myopia

A

nearsightedness caused by the cornea and lens focusing an image ahead of the retina

40
Q

Hyperopia

A

farsightedness caused by the cornea and lens focusing an image behind the retina

41
Q

Astigmatism

A

a condition caused by an irregular curvature of the cornea of the lens of the eye that results in images not being focused on the retina

42
Q

Accomodation

A

the ability of the eye to change the shape of the lens to keep an image in focus with a change in distance

43
Q

Ishihara Test

A

test for color blindness

44
Q

Rinne Test / Weber Test

A

procedures in which a tuning fork is used to test for hearing loss

45
Q

Snellen Test

A

an eye chart used to measure visual acuity
