sarcomere การใช้

• The myofibrils of smooth muscle cells are not arranged into sarcomeres.
• Muscle contraction consists of the simultaneous shortening of multiple sarcomeres,.
• Calcium ions are required for each cycle of the sarcomere.
• The action of myosin attachment and actin movement results in sarcomere shortening.
• PKC? translocates to cardiac muscle sarcomeres and modulates contractility of the myocardium.
• This enables proper assembly of myofibrils and thus, more organized sarcomeres.
• A cell from the biceps brachii muscle may contain 100, 000 sarcomeres.
• The sarcomeres are composed of thin and thick filaments.
• The sarcomere does not contain organelles or a nucleus.
• This causes the filaments to start sliding and the sarcomeres to become shorter.
• Components of this relationship are fiber length, number of sarcomeres and pennation angle.
• Accordingly, myopalladin has functions in both sarcomere assembly and in control of gene expression.
• Calcium is also used in triggering the contraction of muscle fibres ( see Sarcomere ).
• Within the sarcomere, actin and myosin fibers overlap in a contractile motion towards each other.
• Sarcomeres are marked by Z lines which show the beginning and the end of a sarcomere.
• Sarcomeres are marked by Z lines which show the beginning and the end of a sarcomere.
• The Ca2 + flows from the sarcoplasmic reticulum into the sarcomere with both of its filaments.
• Upon stimulation by an action potential, skeletal muscles perform a coordinated contraction by shortening each sarcomere.
• Calcium is released from the sarcoplasmic reticulum into the sarcomere when a muscle is stimulated to contract.
• This protein makes up part of the sarcomere and forms macromolecular filaments composed of multiple myosin subunits.
