Term
| The sliding-filament theory states that the actin filaments at each end of the sarcomere slide ? on myosin filaments, pulling the ? toward the center of the sarcomere and thus shortening the muscle fiber. |

|
|
Term
| proprioceptors that consist of several modified muscle fibers enclosed in a sheath of connective tissue. |
|
Definition
|
|
Term
| When a muscle is stretched, deformation of the ? activates the sensory neuron, which sends an impulse to the spinal cord, where it synapses with a motor neuron, causing the muscle to contract. |
