The area in the center of the sarcomere where only myosin filaments are present:
- correct answers-H-zone
The I-band only contains which type of muscle filaments? - correct answers-Actin
, Actions of the H-zone and I-band during muscle contraction: - correct answers-H-
zone decreases as actin slides over myosin toward the center of the sarcomere
I-band also decreases
Role of a muscle spindle during a muscle contraction: - correct answers-Indicate
the degree to which the muscle must be activated in order to overcome a given
resistance.
As a load increases, the muscle
is stretched to a greater extent, and engagement of muscle spindles results in
greater activation of the muscle

A sensory neuron of the GTO activates an inhibitory interneuron in the spinal cord
that synapses with and inhibits a motor neuron in the same muscle
