Question 2: astigmatism

Answer:

irregularity in the curvature of the lens and or cornea that lead to blurred vision Question 3: transmits the vibratory motion of the stirrup to the fluid in the scala vestibuli of the inner ear

Answer:

oval window

Question 4: Babinski sign

Answer:

toes flare in new borns

Question 5: Glaucoma

Answer:

when intraocular pressure reaches dangerously high levels, the retina and optic nerve are compressed.results in blindness Question 6: vibrates at the same frequency as sound waves hitting it; trnsmits the vibrations to ossicles

Answer:

tympanic membrane

Question 7: aqueous humor

Answer:

anterior part of eye. formed by the capillaries of the ciliary processes of the ciliary body. helps to maintain the intraocular pressure of the eye and provides nutrients for the avascular lens and cornea.

Question 8: Effector

Answer:

muscle fibers or glands, responds to efferent impulses characteristically

Question 9: name the 3 divisions of the cochlea and whats found in each

Answer:

scala vestibuli (peri) scala media (endo) scala tympani (peri)

Question 10: Referred pain

Answer:

when pain is felt in a different area than the original source of pain

Question 11: what are the 3 branches of the aorta?

Answer:

brachiocephalic, L common carotid, L subclavian

Question 12: proprioreceptors

Answer:

respond to internal stimuli but are restricted to skeletal muscles.

Question 13: cornea

Answer:

outermost part of the sclera. clear covering over iris

Question 14: Superficial cord reflexes

Answer:

result from pain and temperature changes. They are initiated by stimulation of receptors in the skin and mucosae. Depend on both on functional upper motorpathways and on the cord-level reflex arc. ex.plantar reflex

Question 15: emmetropic eye

Answer:

Question 19: weber test

Answer:

strike tuning fork, put medially on head. sensorineural deafness-tone heard in unaffected ear.conduction deafness-tone heard more strongly in ear with conduction deafness

Question 20: Flexor Reflex

Answer:

A three-neuron relfex arc. The more synapses encountered in a reflex pathway, the more time is required to effect the reflex.

Question 21: iris

Answer:

the front of the ciliary body and is penet by the pupil. pigmented part of eye

Question 22: Motor neuron

Answer:

Conducts Efferent impulses from the integration center to an effector organ.

Question 23: What are reflexes?

Answer:

Rapid, predictable, involuntary motor responses to stimuli; they are mediated over neural pathways called reflex arcs

Question 24: Spinal Reflex

Answer:

tool used to observe the eye

Question 26: vitreous humor

Answer:

in the vitreous body. in the posterior part of the eye

Question 27: Plantar reflex

Answer:
