1. which of the following is composed of myosin protein? (1 point) thick filaments thin filaments z discs myofilaments 2. which of the following is not an important function of the components of the muscular system? (1 point) mechanical protection heat generation vitamin storage movement of organs 3. an example of a posterior trunk muscle is the (1 point) pectoralis major. internal oblique. rectus abdominus. trapezius.

1. The correct answer is thick filaments. The myosin proteins are accountable for various functions in the body some of which comprise muscle contraction and other mobility procedures whose cells comprise a nucleus and other organelles, which are embedded by membranes. Thus, on the basis of this, it can be concluded that thick filaments constitute myosin protein.  

2. Vitamin storage is not an important function of the muscular system. The muscular system comprises muscle fibers, whose prime function is to perform the process of contractibility.  

3. The correct answer is trapezius. An illustration of the posterior trunk muscle is trapezius, which is accountable for stabilizing, elevating, and depressing the scapula.
