Nociceptors are sensitive to mechanical,thermal,or electrical stimuli,or toxic substances.

There are many more olfactory cells than there are taste buds.

Proprioceptors are classified as which type of receptor?

Order the steps involved in the activity of a muscle spindle: 1.Muscle spindle is stretched.2.Reflex action occurs.3.Contraction of muscle fibers adjoining the muscle spindle.4.Nerve signals are generated.5.The muscle relaxes.6.The muscle's length increases.

What do nociceptors detect?

Nerve signals from taste buds go primarily to the __________ while those for olfactory cells go primarily to the ___________.

What type of exteroceptors are located in the ear?

Describe the steps involved in the action of a muscle spindle.

What controls the shape of the lens?

What type of receptor is involved in reflex actions that maintain muscle tone and,thereby,the body's equilibrium and posture?

All of the parts of the inner ear are concerned with equilibrium.

Gravitational equilibrium is responsible for detecting up and down movements of the head.

Taste and smell are similar in that both respond to some sort of pressure.

Which of the following is part of the middle ear?

List the four categories of sensory receptors and describe what they respond to.
