Exam 17: A: Sense Organs

A new primary taste,called umami,found in protein foods has been proposed by researchers.

Somatic sense receptors located in muscles and joints are called proprioceptors.

Recovering from the effects of rapidly traveling through many time zones (jet lag)requires the functioning of the ganglion cells of the eye.

The terms sensation and perception mean the same thing.

Because rhodopsin is less sensitive to light than the cone photopigments,brighter light is necessary for its breakdown.

Movement of hair cells in the organ of Corti against the cochlear membrane can stimulate nerve impulse conduction.

Golgi tendon receptors are stimulated by touch.

The white of the eye is called the choroid.

Taste buds are both exteroceptors and chemoreceptors.

Special sense organs can respond to only one type of stimuli,whereas general sense organs can respond to several different types of stimuli.

Convergence of impulses from cones is common.

Osmoreceptors monitor the concentration of glucose in the blood.

High-frequency sound waves cause the narrow portion of the basilar membrane near the oval window to vibrate.

The canal of Schlemm drains the aqueous humor from the anterior chamber.

The section below the cochlear duct is called the scala vestibuli.

Movement of the eyeball in any desired direction is accomplished by several intrinsic muscles.

There are three semicircular canals.

The function of the eustachian tube is to equalize all pressure on either side of the oval window.

Anatomically,each muscle spindle consists of a discrete grouping of about 5 to 10 modified muscle fibers called intrafusal fibers.

Osmoreceptors measure the type of chemicals in the blood and stimulate the hypothalamus.
