When a skeletal muscle was passively stretched, it contracted reflexly. However, when the muscle was over stretched in dos way it showed sudden cessation of contraction followed by relaxation, The […]

When a skeletal muscle with an intact nerve supply is stretched, the muscle contracts and the tone increases. The following explanations are offered for this observation: A. Golgi tendon organ […]

A myasthenia gravis patient develops muscle paralysis because (1) the nerve terminal at the neuromuscular junction fails to release acetylcholine. (2) although enough acetylcholine is released at the neuromuscular junction, […]

A patient has episodes of painful spontaneous muscles contraction, followed by periods of paralysis of the affected muscles. It was identified as primary hyperkalemic paralysis, an inherited disorder. The possible […]

Which one of the following skeletal muscles of human body contains highest number of muscle fibre in a motor unit? (1) Muscles of hand (2) Extraocular muscles (3) Muscles of […]

When ATP remains attached with the myosin head, which one of the following event happens in the skeletal muscle? (1) Muscle contraction. (2) Muscle relaxation. (3) Muscle rigor. (4) Muscle […]

Cardiac muscles cannot undergo tetany because of (1) Resistant to tetanus toxin (2) auto-rhythmicity (3) Do not need calcium ions (4) highly evolved muscles Cardiac muscles differ fundamentally from skeletal […]

Among the following which muscle protein as affinity to bind with Ca++ ions? (1) Tropomyosin (2) Troponin (3) Actin (4) Myosin Among the key proteins involved in muscle contraction, troponin is the […]

A football player injured in the heat of play did not feel pain until the game was over. This stress-induced analgesia was explained by the following proposed statements: A. The […]

The peaks of the compound action potential (i.e., A, B and C) recorded from a mammalian mixed nerve were affected after application of increasing pressure on the nerve. Some probable […]
