false

free nerve endings of sensory neurons are rare and found in few locations within the body

true

many sensory receptors are capable of adaption to a reoccurring stimulus

true

muscle spindles that function in coordination of muscle activity are compromised of several intrafusal muscle fibers wrapped in a connective tissue capsule and have central non contractile regions

false

true

pain originating from the heart might be referred to in the left jaw and neck of an individual

head

tonic

receptors give a sustained response to a stimulus with little or no adaptation

Meissener's Corpuscles

receptors respond to light, touch, and low frequency vibrations

true

reciprocal inhibition and activation occur in stretch and tendon reflexes and help to regulate onset and terminations of muscle contractions and relaxations
