Question

20 multiple choice 0.7 points which of the following statements about the sliding filament theory are true? actin pulls myosin the actin filaments lengthen, while the myosin filaments shorten actin and myosin filaments stay the same size during contraction the binding site for a cross - bridge is found on myosin 21 multiple choice 0.7 points which of the following would most likely be unconscious sensory information? special senses visceral stimulation somatic senses itch

Explanation:

In the sliding - filament theory, during muscle contraction, actin and myosin filaments slide past each other but do not change in length. For the second question, visceral stimulation often occurs unconsciously as it is related to the internal organs and their functions. Special senses (vision, hearing, etc.) are often conscious, somatic senses (touch, pain in the body) can be conscious, and itch is a conscious sensation.

Answer:

1. Actin and myosin filaments stay the same size during contraction
2. visceral stimulation
