Within a muscle, the muscle fibers are functionally organized as motor units. A motor unit consists of a single motor neuron and all of the muscle fibers it innervates. The size of the unit can involve only a few fibers for fine movement to huge numbers for gross movement such as what occurs in walking. The force generated by muscles to lift a feather is much less than the force required to ...
A motor neuron and all of the skeletal muscle fibers it innervates is called a: A. Myofiber B. Motor unit C. Myofibril D. Sarcomere Which of the following correctly defines a motor unit? a) A single neuron and all the muscle cells it innervates b) All motor units are afferent neurons c) A single muscle and its largest associated nerve d) A ...
Motor development, or the ability to control physical movement, changes from infancy to childhood to adolescence. Gross motor development is the ability to control movement in the large muscle groups.
Motor unit recruitment B. Tetanus C. Motor unit suppression D. Muscle twitch E. Contraction phase Muscles that have actin and myosin filaments arranged in large bundles that are parallel a) Are found in the stomach, intestine, and uterus b) Are found in smooth muscle c) Are found in skeletal and cardiac muscles d) Lack striations
