What is the optimum muscle activity to undertake for muscular hypertrophy? Explain deeply.
Impairment of intracellular calcium homeostasis in muscle fibers lead to chronic, severe muscle dysfunction. Impaired Calcium ATPase activity can lead to abnormal, persistent elevation of intracellular calcium concentrations. Explain how persistently high intracellular calcium concentration would affect cross-bridge formation, and muscle contractions, and muscle tension? (Mention the effects on the steps involved cross bridge formation, and muscle contraction/relaxation cycle, and overall muscle tension).
Define and describe hypertrophy of skeletal muscles. Whatconditions stimulate it?

Which of the following is/are correct? A) The brain stops sending the nerve impulse that commands the muscle to contract, interrupting communication at the neuromuscular junction B) Acetylcholineesterase (AChE) is released into the synaptic cleft to destroy any remaining Acetylcholine C) No mechanism is necessary. When the antagonist begins to contract, it forces relaxation and stretch of the agonist muscle. D) Relaxation occurs as the myosin heads are "snapped" off of the thick filaments. This interrupts the crossbridge and allows for muscles to stretch E) Relaxation only occurs if the brain sends a "stop" signal to the musclearrow_forward
