Isometric contraction occurs when muscle length remains relatively constant as tension is producedIsometric exercises are often used during the early phases of rehabilitating a musculotendinous injury because the intensity of contraction and the muscle length at which it contracts can be.

. Which of the following occurs during the latent period of muscle contraction. Tropomyosin moves exposing the actin active sites. Calcium is resequestered taken up into the sarcoplasmic reticulum.

The signal an impulse called an action potential travels through a type of nerve cell called a motor neuron. The T-tubules depolarize causing calcium to be released from the sarcoplasmic reticulum. Medium View solution During muscular contraction which of the following events occur.

The muscle contraction cycle is triggered by calcium ions binding to the protein complex troponin exposing the active-binding sites on the actin. Calcium Binds with Troponin. D Calcium concentration in the sarcomere increases.

Why the muscle contracts isometrically before it shortens. _____ 9 Muscle fibers designed for rapid and powerful responses. The myosin filaments shorten.

Choose the correct answer from the options given below. 1 the I band becomes larger 2 the distance between the Z lines becomes larger 3 the sarcomere becomes smaller 4 the A band becomes smaller 5 the H zone reappears. Iv Width of the A-band is unaffected.

Cross Bridges are formed between actin and myosin. Tropomyosin changes shape conformation to expose myosin binding sites. The distance between the z-discs lengthens The A band shortens The I band and the A band switch positions thick and thin myofillaments shorten The sarcomeres shorten Jogging swimming and aerobics all have this effect on skeletal muscle tissue.

Fitness-and-wellness More questions like this. B Muscle tension is produced and the weight will not move. Muscle tension is not produced and the weight will not move.

An eccentric lengthening muscle contraction occurs when a force applied to the muscle exceeds the momentary force produced by the muscle itself resulting in the forced lengthening of the muscle-tendon system while contracting Lindstedt et al 2001. B A band widens. Muscle contraction is the tightening shortening or lengthening of muscles when you do some activity.

_____ 11 Bind to troponin in the sarcomere to initiate muscle contraction. ACh binds to receptors on the sarcolemma causing an electrical disturbance B. E Hemoglobin concentration in muscle fibers increases.

Muscle contraction begins when the nervous system generates a signal. Muscle contraction is often followed by muscle relaxation when contracted muscles return to their normal state. Which of the following occurs during a muscle contraction.

E Z-lines attached to actins are pulled inwards. Muscle tension is produced and the weight will not move B. The actin filaments shorten.

V M-line and Z-line come closer. Iii I-band reduces in width. A Sodium ions to bind to the thin filament B Acetylcholine to bind to the sarcolemma receptors Production and presence of adenosine triphosphate ATP С D Nerve impulse action potential This problem has been solved.

Skeletal muscle tissue is composed of cells called muscle fibers. C I band reduces in width. ATP then binds to myosin moving the myosin to its high-energy state releasing the myosin head from the actin active site.

Muscle tension is not produced and the weight will move D. Muscle Contraction Steps in Detail A signal is sent from the brain or the spinal cord to the muscle via neurons. 2 a c d e.

State the condition of muscle contraction in following diagram. Which of the following describes and eccentric muscle action. 48 A Muscle tension is not produced and the weight will move.

Which of the following occurs during the latent period of isotonic concentric contraction. C Acetylcholine is released at the axon terminal and an action potential is generated. 73 During muscle contraction all of the following occur except A ATP is hydrolyzed.

_____ 8 Functions in the attachment of muscle to bone. This makes the sarcomeres shorter and thicker contracting the muscle. It can happen when you hold or pick up something or when you stretch or exercise with weights.

B Calcium is released from the sarcoplasmic reticulum. Which of the following occurs first in muscle contraction. The innervating alpha-motor neuron reaches an action potential.

Myosin globular head uncoils releasing stored energy. _____ 5 10 Muscle fibers that are designed for endurance contract slowly and have a steady supply of energy. D Muscle tension is not produced and the weight will not move.

Which of the following occurs during the latent period of isotonic concentric contraction. When sarcomeres contract during muscle contraction which of the following occurs. 1 a b c d only.

B Myosin heads bind to actin. When the CNS sends a signal the thick and thin myosin filaments form a crossbridge pattern by sliding past each other. Skeletal muscles are stimulated to contract when.

Muscle tension is produced and the weight will move C. A H zone disappears. So the correct option is Z lines move closer together.

C Muscle tension is produced and the weight will move. D Myosine hydrolyzes ATP releasing the ADP and Pi. C The H band becomes shorter.

Which of the following occurs during skeletal muscle contraction. Medium View solution View more. The myosin filaments lengthen.

See the answer 32. During muscular contraction which of the following events occur. Question 32 Which of the following is NOT necessary for muscle contraction to occur.

What are the steps in muscle contraction. Asked Dec 17 2020 in Anatomy Physiology by Jn678 A An action potential is generated. ATP is released from the sarcoplasmic reticulum Calcium is actively pumped into SR CCalcium binds to the sarcolemma causing an electrical disturbance DACh diffuses into the sarcoplasm.
