Exam 4 Review

Front

What is the primary function of the cerebellum?

Back

The cerebellum plays a role in muscle movement.

Front

What type of stimulus do Meissner cells respond to?

Back

Meissner cells respond to light touch.

Front

What type of stimulus do Pacinian corpuscles respond to?

Back

Pacinian corpuscles respond to vibration pressure.

Front

What is the adaptation rate and receptive field size of Merkel discs?

Back

Merkel discs are slowly adapting with a small receptive field.

Front

What is the adaptation rate and receptive field size of Pacinian corpuscles?

Back

Pacinian corpuscles are rapidly adapting with a large receptive field.

Front

Define 'receptive field' in the context of sensory cells.

Back

A receptive field is the specific area where a sensory cell can detect stimuli.

Front

What is the difference between rapidly adapting and slowly adapting receptors?

Back

Rapidly adapting receptors respond quickly to changes in stimulus and stop firing when the stimulus is constant, while slowly adapting receptors continue to respond as long as the stimulus is present.

Front

What role do sensory receptors play in the nervous system?

Back

Sensory receptors detect environmental stimuli and convert them into neural signals for processing by the nervous system.

Front

Explain the concept of sensory adaptation.

Back

Sensory adaptation is the process by which sensory receptors become less sensitive to constant stimuli over time.

Front

What type of sensory information do mechanoreceptors detect?

Back

Mechanoreceptors detect mechanical pressure or distortion.
