Neuro III, Senses - Chapter Assessment

A sensory receptor capable of detecting changes in hydrogen ion concentration is more accurately described as a ______________.

• Thermoreceptor

• Pain receptor

• Mechanoreceptor

• Chemoreceptor

Heavy pressure and vibrations stimulate ________________.

• Proprioceptors

• Baroreceptors

• Meissner's corpuscles

• Pacinian corpuscles

Choose the statement about the sense of pain that is correct.

• Pain receptors are among many types of receptors in the viscera that produce sensations.

• A phenomenon known as referred pain can be explained because of common nerve pathways used by both the skin and internal organs.

• Acute pain fibers are never myelinated.

• Chronic pain fibers stop sending signals as soon as the stimulus ceases.

What type of somatic receptor lies within tendons close to the point of attachment to muscles and is stimulated by increased muscular tension?

• Golgi tendon organ

• Muscle spindle

• Free nerve ending

• Meissner's corpuscle

Which of these statements about the sense of smell is not true?

• Olfactory receptor cells are bipolar neurons that are not replaced when damaged.

• Chemicals are received by specific plasma membrane receptors in the olfactory receptor cells.

• Olfactory receptors do not adapt quickly.

• The main areas of the brain that interpret the sense of smell lie in the temporal and frontal lobes.

The portion(s) of the tongue that actually perceives taste is/are the _____________.

• Taste hairs

• Papillae

• Epithelium of tongue

• Taste buds

How do the senses of smell and taste differ?

• They differ in the types of receptors they employ.

• They differ in the reproductive rate of the receptors.

• They differ in their rate of sensory adaptation.

• They do not both employ cilia or hair-like extension of their receptor cells.

Why do odors sometimes alter our moods?

• Because sensory input from olfaction is routed through the limbic system.

• Because odors act as neurotransmitters and alter brain chemistry.

• Because odors are satisfying to our sense of hunger.

• Odors do not alter mood.
