61.Both multi-unit and single-unit smooth muscle under motor control from : 1417096
61.Both multi-unit and single-unit smooth muscle are under motor control from the autonomic nervous system.
62.All smooth muscle is myogenic.
63.The strength and rate of contraction of the heart can be influenced by the autonomic nervous system.
64.The heart initiates its own action potentials without any external stimulation.
65.When considering the muscle as part of a lever system, a calculated “moment” for the muscle would be force times power arm length.
66.Asynchronous recruitment gives motors units that have been active an opportunity to rest while others are firing.
67.Creatine kinase donates one of its own phosphates to creatine to convert the creatine to creatine phosphate.
68.Red muscle fibers contain myoglobin, but white muscle fibers do not.
69.Part of the excess postexercise oxygen consumption is due to increased speed of chemical reactions resulting from an increase in body temperature.
70.Flaccid paralysis in a condition in which skeletal muscles receive an increase in inhibitory input from higher brain centers.
71.Sarcopenia is a type of muscular atrophy that involves the body’s immune system attacking certain skeletal muscles.
72.Following muscle damage, a limited number of satellite cells located near a skeletal muscle’s surface can develop into myoblasts that fuse together to form new skeletal muscle cells.
73.Slow-wave potentials are common in multiunit smooth muscle located in the walls of organs in the digestive system.
74.Phasic smooth muscle is abundant in the walls of hollow organs of the digestive system and contract in bursts of contractile activity.
75.The latch phenomenon in which myosin cross bridges hold onto thin myofilaments for a relatively long period is not a characteristic of skeletal muscle cells.
