Exam 17: A: Sense Organs

Strabismus is more of a problem with the internal ciliary muscle than with the external muscles.

Sensations produced by receptors of general senses are often called somatic senses.

The opening and separation of opsin and rhodopsin in the presence of light is called bleaching.

Chemical structure of a food is the sole determinant of its flavor or taste.

Walking would stimulate tonic proprioceptors.

Dynamic equilibrium depends on the functioning of the crista ampullaris.

Refraction means the deflection,or bending,of light rays.

Referred pain is psychosomatic pain brought on by intense stress.

The treatment of fibromyalgia requires an increase of calcium ions in the pain centers of the spinal cord.

The pupil is an opening in the middle of the iris.

The cell most likely to be found in the fovea centralis of the eye would be a rod cell.

The eye is the only organ in the body in which both voluntary and involuntary muscles are found.

Three processes focus light rays so that they form a clear image on the retina: refraction of the light rays,constriction of the pupil,and convergence of the eye.

Aqueous humor is formed by secretion of the ciliary body into the posterior chamber.

The retina is the incomplete innermost coat of the eyeball,in that it has no anterior portion.

The two fluids of the middle ear are perilymph and endolymph.

The slow adaptation of the sense of smell is due to the adaptation inhibition of the granule cells in the olfactory bulb.

The auditory ossicles include the malleus,incus,and stapes.
