Explanation / Answer

1. When a motor unit is sufficiently stimulated, then all of the muscle fibers in that motor unit will contract. (true)

2. Based on the name of the muscle pronator teres,

Its shape, Its action, Its number of muscle heads (two heads), Its body region can be said.

3. The function of skeletal muscle tissues are:

Body movement, Maintenance of body posture, heat production, regulating the elimination of materials, protection, and support.

4. Myotomes in a developing limb is divided into dorsal and ventral muscle masses. The dorsal region forms the muscle of the neck and the vertebral column and the ventral region forms the muscle of the body wall. (true)

5. While standing on both feet and bringing one foot up to touch the heal of the foot of the buttocks. The hamstring muscles are acting as an agonist.

6. The organizational level of muscle tissue beginning with muscle and ending with the smallest component is as follows:

muscle, fascicle, muscle fibers, myofibril, myofilament.
