Muscle Twitch Phase Lag What is occurring inside muscle fiber Be Specific here Stage of Action Potential (depolarization, repolarization) Depolarization Crossbridge stage Of myosin and actin Contraction Depolarization Resting Repolarization Note: we will discuss this more later

Hi can you please help me in those activities. Already tried to draw them but it’s wrong .

When the action potentials stop, the concentrations of the contraction cycle. calcium O ATP O phosphate O sodium inside the muscle cells will drop and mark the end of

match to correct box

What is the steps in the Sliding Filament theory of muscle cell contraction in correct order? Including steps in depolarization and repolarization.

Explain in detail: What does the ‘sliding filament model of muscle contraction’ discuss or explain? What are filaments composed of and how do contractions occur, commenting on calcium and ATP process.

Which of the following are correct regarding processes that are involved in the Latent period of a muscle twitch? (choose all that apply) Acetylcholine binds to nicotinic receptors on the motor-end-plate Myosin binds with Actin forming the "cross-bridge" Power-Stroke Cycling is occurring Action potential travels down T-Tubules O Calcium is released from Terminal Cisternae and binds to Troponin

Discuss what happens to each of the following to allow for skeletal muscle relaxation: ACh, action potential, Ca2+ concentration in sarcoplasm, and troponin-tropomyosin complex.
