BT_PO 1.98a Physiology of Skeletal Muscle

I thought that this week, we could focus on the neuromuscular junction.

BT_PO 1.98a Describe the physiology of skeletal muscle including mechanism of excitation contraction coupling and compare the physiology of skeletal muscle with that of cardiac muscle.

TRUE/FALSE Most muscle fibres have only one neuromuscular junction.

TRUE/FALSE Activation of skeletal muscle acetylcholine receptors caused depolarisation by efflux of K+ ions.

TRUE/FALSE ATP can only supply energy for skeletal muscle contraction for 5-8 seconds.

TRUE/FALSE In the final stage of denervation atrophy, muscle cells have little capability to regenerate myofibrils.

TRUE/FALSE Skeletal and cardiac muscle act as a functional syncytium during depolarisation.
