What three steps are necessary for transduction to occur?

Match the receptor type in column B to the correct description in column A. Column A______(1) pain, itch, and temperature receptors______(2) contains intrafusal fibers and anulospiral and flower spray endings______(3) discriminative touch receptor in hairless skin (fingertips)______(4) contains receptor endings wrapped around thick collagen bundles______(5) rapidly adapting deep-pressure receptor______(6) slowly adapting deep-pressure receptor Column Ba. bulbous corpusclesb. tendon organc. muscle spindled. free nerve endingse. lamellar corpusclef. tactile corpuscle

The CNS interprets information entirely on the basis of the (a) number of action potentials that it receives, (b) kind of action potentials that it receives, (c) line over which sensory information arrives, (d) intensity of the sensory stimulus, (e) number of sensory receptors that are stimulated.

Identify six types of tactile receptors located in the skin, and describe their sensitivities.

What three types of mechanoreceptors respond to stretching, compression, twisting, or other distortions of their plasma membrane?

All of the following descriptions refer to dorsal column–medial lemniscal ascending pathways except one:a. they include the fasciculus gracilis and fasciculus cuneatus;b. they include a chain of three neurons;c. their connections are diffuse and poorly localized;d. they are concerned with precise transmission of one or a few related types of sensory input.

Differentiate between a tonic receptor and a phasic receptor.

Differentiate clearly between sensation and perception.
