<span>The autonomic nervous system
The autonomic nervous system (ANS) is the part of the peripheral nervous system that acts as a control system, functioning largely below the level of consciousness and controlling visceral functions. The ANS affects heart rate, digestion, respiratory rate, salivation, perspiration, pupillary dilation, micturition (urination), and sexual arousal. The ANS is classically divided into two subsystems: the parasympathetic nervous system (PSNS) and sympathetic nervous system (SNS).</span>
Hi there!
Potential energy is idle energy such as that of the frog preparing to leap or a roller-coaster at the peak of it's height. From that we can conclude that the from leaping is kinetic energy since the frog is using it's stored up potential energy to leap.
Answer:
Sarcomere
Explanation:
The sarcomere is the smallest contractile unit of muscle. It extends from one Z disc to the next and therefore, is the region between two consecutive Z discs. It contains an A band flanked by half an I band at each end. Contraction of a muscle fiber occurs as the sarcomeres within the myofibrils shorten. During the shortening of the sarcomere, the thin actin filaments slide past the thick myosin filaments and approach one another. The resultant shortening of the I band and complete disappearance of H zone cause contraction of muscle fiber.
