true
as a rule mature neurons do not divide
false
every individual has a unique pain perception threshold
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
nerves do not regenerate well because they do not have a blood supply
false
only ventral rami of spinal nerves form plexuses
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
Proprioceptors
sensory receptors providing information regarding spatial location of body structures would best be termed as

motor
ventral roots of spinal nerves have ____ functions
true
