Q

Alpha-2 Receptor Agonists

A

Treat hypertension; stimulate these receptors to inhibit sympathetic vasomoter centers

1
Q

Alpha-1 Receptor Agonist

A

Treat hypotension; stimulate these receptors to cause vasoconstriction of blood vessels

2
Q

beta-adrenergic blockers

A

Decrease heart rate and contraction force; lower peripheral blood pressure by acting on these receptors to diminish the effects of epinephrine

3
Q

parasympathetic blocking agents

A

Drugs that target the muscarinic receptors at neuromuscular or neuroglandular junctions

4
Q

parasympathomimetic drugs

A

Mimic this system and increase activity of digestive tract

5
Q

sympathetic blocking agents

A

bind to receptor sites & prevent normal response to neurotransmitters or sympathometic drugs

6
Q

sympathometic drugs

A

drugs that mimic the effects of sympathetic stimulation

7
Q

age-related macular degeneration

A

gradually destroys sharp, central vision. Two forms: wet and dry

8
Q

aguesia

A

a rare inability to taste, or hypo- diminished ability to distinguish taste

9

11
Q

conductive deafness

A

deafness resulting from conditions in the external or middle ear that block the transfer of vibrations from tympanic membrane to the oval window

12
Q

hyposmia

A

a lessened sensitivity to odors

13
Q

mydriasis

A

dilation of the pupils of the eye induced by medical eye drops or disease

14
Q

nerve deafness

A

deafness resulting from problems within the cochlea or along the auditory nerve pathway

15
Q

otalgia

A

earache

16
Q

photophobia

A

oversensitivity to light due to abrasions to the cornea, inflammation, disease or medications

17
Q

strabismus

A

The abnormal alignment of eyes that prevents the person from gazing at the same point with both eyes

18
Q

synesthesia

A

Abnormal condition in which sensory nerve messages connect to the wrong centers of the brain. i.e. hearing colors

19
Q

tinnitus

A

a buzzing, whistling or ringing sound heard in the absence of external stimulus

20
Q

vertigo

A

a feeling of dizziness caused by problems in vision or the internal ear

21
Q

scotoma

A

abnormal blind spots

22
Q

retinitis pigmentosa (RP)

A

a collection of inherited retinopathies; most common inherited abnormality. Visual receptors gradually deteriorate. Mutations change the structure of the visual pigments of membrane discs (i.e. rhodopsin)

23
Q

nyctalopia

A

night blindness; caused by dietary lack of vitamin A. Visual pigments are synthesized from vitamin A, & gradually decline.

24
Q

nystagmus

A

uncontrollable eye movements while stationary which are normally associated with compensation for spinning/twirling.
