Consider the following statements regarding Muscle Tissue.
. The myosin in smooth muscle requires phosphorylation before it can bind to ATP. Muscle tissue is contractile tissue grouped into coordinated systems for greater efficiency. The binding of calcium to Calmodulin is responsible for initiating contraction c.
The latch state reduces the expenditure of ATP in smooth muscle. The biceps and quadriceps are examples of smooth muscle. Smooth muscle does not have thick and thin filaments C.
A person has no voluntary control over smooth muscle. It is greater than the load during an isometric contraction. In skeletal muscle cells EC coupling begins when an action potential propagates along the sarcoplasmic reticulum membrane.
Which of the following statements about smooth muscle contraction is correct. 11 The muscular coat of the bladder is composed of smooth muscle which at the bladder neck is thickened to form the sphincter vesicae. Contractions in skeletal and smooth muscles occurs.
The sympathetic postganglionic fibers originate in the first and second lumbar. C Certain smooth muscle cells can actually divide to increase their numbers. Blood vessels urinary bladder ciliary body etc.
In skeletal muscle calcium ions bind to a regulatory protein on thin filaments. A Smooth muscle in contrast to skeletal muscle cannot synthesize or secrete any connective tissue elements. None of the statements are correct.
Correct option is D Skeletal muscle is a voluntary muscle whereas cardiac muscle is an involuntary muscle. In skeletal muscle calcium initiates contraction by binding to troponin while in smooth muscle calcium initiates contraction by binding to calmodulin. A person has no voluntary control over smooth muscle.
Thus the correct answer is option D. Smooth muscle does not use changes in cytosolic calcium to regulate cross-bridge activity E. Which of the following is true about smooth muscle.
In skeletal muscle Ca2 binds to troponin while in smooth muscle Ca2 binds directly to myosin. Smooth muscle has the fastest myosin ATPase activity compared to skeletal and cardiac muscle. Which of the following statements regarding smooth muscle is true.
Which of the following statements regarding contraction in skeletal and smooth muscle is TRUE. Which of the following statements regarding the Urinary Bladder is not correct. Which of the following statements is true about smooth muscle.
Each muscle is made of numerous fine fibrils called myofibrils. B Unlike striated muscle contraction of smooth muscle cells occurs when Ca 2 levels fall. Which of the following statements regarding contraction in skeletal and smooth muscle is TRUE.
In humans the muscle systems are classified by gross appearance and location of cells. Which of the following statements regarding corttraction in the skeletal and smooth muscle is true. Calcium-induced calcium-release plays a role in cardiac muscle cells as well as in some smooth muscle cells.
Smooth muscles are controlled by the autonomic division. Smooth muscle does not use troponin-tropomyosin to regulate cross-bridge activity D. 1 Which of the following statements regarding contraction in skeletal and smooth muscle is TRUE.
In skeletal muscle calcium initiates contraction by binding to troponin while in smooth muscle calcium initiates contraction by binding to calmodulin. Smooth muscles are unstriated. Smooth muscles are involuntary and involved in muscular contraction of visceral organs.
In skeletal muscle calcium initiates contraction by binding to myosin light-chain kinase while in smooth muscle calcium initiates contraction by binding directly to tropomyosin. Smooth muscles do not possess alternate dark and light bands. Which of the following statements are correct regarding the somatic nervous from PHYS 560 at St.
All of the above. Cardiac muscle tissue is a contractile tissue present only in the heart. The three types of muscles are striated or.
In smooth muscle calcium. Smooth muscle is found exclusively within blood vessels. Solve any question of Structural Organisation In Animals with-.
Smooth muscle has more troponin than skeletal muscle. Smooth muscle receives neural input from the somatic nervous system. In skeletal muscle Ca2 initiates contraction by binding to myosin light-chain kinase while in smooth muscle Ca2 initiates contraction by binding.
It is the force exerted on a muscle by the weight of an object. The nerve supply of the smooth muscle is from the celiac plexuses. The troponin tropomyosin mechanism of controlling contraction is present in skeletal muscles and absent in smooth muscles.
B Smooth muscle has well-developed T tubules at the site of invagination. Smooth muscle is under control of the voluntary nervous system. Smooth muscles are voluntary as their functioning can be directly controlled.
Smooth muscle has a wider range for optimal length and force development than skeletal muscle. It created during muscle contraction as the tension generated by the contractile elements is transmitted via the connective tissue and tendons to the bones b. In skeletal muscle calcium initiates contraction by binding to troponin while in smooth muscle calcium initiates contraction by binding to calmodulin.
Both b and c correct. The biceps and quadriceps are examples of smooth muscle. Smooth muscle is found exclusively within blood vessels.
Inhibition of the myosin kinase light chain increases the force of contraction d. Muscle Contraction occurs in both skeletal and smooth type of muscles. In skeletal muscle calcium initiates contraction by binding to myosin light chain kinase with in smooth muscle calcium initiates contractions by binging directly to troponin.
A A Ca 2 -calmodulin complex activates the phosphatase that causes contraction of smooth muscle. Nitric oxide stimulation of smooth muscle cells will increase contraction b. Which of the following statements regarding smooth muscle is correct.
Smooth muscle is under control of the voluntary nervous system. Actin and myosin generate force through the crossbridge cycle.
