Q

You should be able to state what readings from a Snellen Acuity card mean i.e. what does 20/20 vision mean? What does 20/40 vision mean? What does 20/15 vision mean?

A

You use a Snellen Acuity card to measure visual acuity. 20/20 vision is normal. 20/40 vision means that you see at 20 feet what a person who has normal vision sees at 40 feet (worse than normal vision). 20/15 vision means that you see at 15 feet what a person who has normal vision sees at 20 feet (better than normal vision)

69
Q

What types of equilibrium receptors are present in the ear and where are they located?

A

Two types of equilibrium receptors - the maculae, located in the utricle and saccule, and the cristae, located in the membranous semicircular ducts within the ampullae.

The maculae provide information on head position (Static equilibrium) as well as linear acceleration and deceleration. Consits of hair cells with hair bundles and supporting cells.

The cristae detects rotational acceleration and deceleration, a type of dynamic equilibrium. Each crista consits of hair cells and supporting cells.

70
Q

What and where are hair cells in the ear?

A

Hair cells are ceptors for hearing and are located in the spiral organ of Corti.

71
Q

What are otoliths?

A

calcium carbonite crystals in the otolithic membrane. Movement of the head causes movement of the otoliths and otolithic membrane, which bends hair bundles of the maculae.

72
Q

Where is the olfactory epithelium located?

A

olfactory epithelium covers the inferior surface of the cribriform plate, the superior nasal concha, and the upper part of the middle nasal concha.

The olfactory epithelium contains olfactory receptor cells, supporting cells, basal stem cells, and ducts of olfactory glands.

73
Q

What are the 4 primary taste sensations?

A

sweet, salty, bitter, and sour.

74
Q

What has been postulated as a fifth possibility (as a primary taste sensation)?

A

umami

75
Q

What does the term astigmatism mean? Astigmatism is defined in the glossary of your textbook.

A

An irregularity of the lens or cornea of the eye causing the image to be out of focus and producing faulty vision.
