Q1 Muscle contraction can be understood as the consequence of a process of transmission of action potentials from one neuron to another. A chemical called acetylcholine is the neurotransmitter released from the presynaptic neuron. As the postsynaptic cells on the muscle cell membrane receive the acetylcholine‚ the channels for the cations sodium and potassium are opened. These cations produce a net depolarization of the cell membrane and this electrical signal travels along the muscle fibers. Through

There are three phases for muscle cell contraction: initiation of action potential in the sarcolemma‚ excitation-contraction coupling‚ and contraction‚ sliding of the myofilaments. ATP and calcium ions are two essential elements for muscle contraction. When ATP attaches to the myosin head‚ it gets hydrolyzed to ADP and Pi. Calcium ions bind to the troponin molecules and help expose the binding sites of actin filaments to allow for the attachment of the myosin heads. After the sliding of the myofilaments

My writing process all depends on what I am writing. Some writings I can sit down and write the whole things and be done with it‚ while others can take me multiple days or even weeks. I normally sit down and work on it until I finish‚ get tired of it‚ or a hit a roadblock.
