What stimulated the rapid discovery
To accomplish a strong contraction that is stimulated at a rapid rate, the muscle fibers need sufficient ATP for energy production, calcium ions for muscle contraction, and acetylcholine for nerve stimulation. Additionally, a well-coordinated activation of motor units is necessary to achieve a strong and rapid contraction.
Peristalsis involves circular smooth muscles and longitudinal smooth muscles in the effort to produce waves of contractions in a tube. This process is used in digestion to move the food (bolus) through the esophagus and the chyme (partially digested food) through the intestines.
Muscular respiration, muscle contraction is an exothermic [heat producing] reaction, this includes smooth and skeletal muscle. Your smooth muscle is constantly being innervated/stimulated without your awareness via your autonomic nervous system, most of you organs are made of smooth muscle, so like ur heart kidney and liver are constantly warm because theyre always working to keep you alive. which is why your insides dont go numb like ur toes. Skeletal; muscle requires you to actually want to move it for it to move, like going for a run warms you up, if you get really really cold tho the thermoregulation centre in the animals brain, the hypothalamus in humans, will stimulate ur skeletal muscle for you, this rapid contraction of skeletal muscle is more commonly refered to as shivering.
many motor units are stimulated
The advantage of having smooth muscle lining the intestinal tract is that it allows for involuntary, continuous, and rhythmic contractions, which are essential for peristalsis and the movement of food through the digestive system. Unlike skeletal muscle, which is under voluntary control, smooth muscle operates autonomously, enabling the digestive processes to function without conscious effort. Additionally, smooth muscle's ability to contract slowly and sustain long periods of tension is ideal for the gradual processing and mixing of food, unlike the rapid contractions of cardiac or skeletal muscle.
Rapid City Muscle Car was created on 1994-12-12.
Skeletal muscle twitch is a single, brief contraction and relaxation cycle, whereas a tetanic contraction involves sustained, rapid repeated contractions without relaxation in between. Tetanic contractions occur when the muscle is stimulated at a high frequency, leading to a fused contraction.
Substance P is a 11 amino-acids peptide which belongs to the tachykinins, a family of peptide which induces a rapid contraction of the smooth muscle of the digestive tract
