Answer: Peripheral nervous system
⫸ sense distortion in body tissues. Answer: mechanoreceptors
⫸ mechanoreceptor that senses changes in tension. Answer: Golgi
tendon organs
⫸ mechanoreceptor that senses changes in length. Answer: muscle
spindles
⫸ cumulative sensory input to the CNS from all mechanoreceptors.
Answer: proprioception
⫸ connect muscle to bone, anchor to produce force, limited blood flow,
slow to repair. Answer: tendons
,⫸ individual contractile units, actin and myosin filaments. Answer:
sarcomeres
