Exam 17: A: Sense Organs

Merkel disks and muscle spindles provide the body with information about muscle and the strength of muscle contraction.

Muscle tissue responds to efferent gamma neurons and afferent alpha neurons.

Tactile disks adapt rapidly to make sure current information is being sent to the brain.

The eustachian tube connects the inner ear with the trachea.

Golgi tendon receptors respond in a way similar to muscle spindles to maintain posture.

Sensory receptors make it possible for the body to respond to stimuli caused by changes occurring in our external and internal environments.

Referred pain may be caused by deep organ receptors and skin area receptors entering the same segment of the spinal cord.

The frequency of a sound determines its pitch.

Unlike other neurons,olfactory receptors are replaced on a regular basis.

The hearing sense organ is the organ of Corti.

The correct order of the flow of tears is lacrimal gland,lacrimal duct,punctum,lacrimal sac,lacrimal canal,and nasolacrimal duct.

The number of sound waves that occur during a specific timeframe is called its frequency.

The function of a receptor is to turn a stimulus into a nerve impulse.

Perilymph is similar to cerebrospinal fluid and surrounds the membranous labyrinth.

The membranous labyrinth is filled with perilymph.

Taste buds are stimulated by chemicals called tastants.

The two-point discrimination test measures the visual acuity of the eye.

Mechanoreceptors are the simplest,most common,and most widely distributed sensory receptors.

The Ruffini corpuscle is an example of a bulboid corpuscle.

All taste buds are located on the tongue.
