The mechanism by which skeletal muscle tissue obtains ATP to fuel contractions is the sliding - filament hypothesis. Two filaments, actin and myosin, slide over one another during contraction.

∙ 10y agoMuscle fiber generates tension through the action of actin and myosin cross-bridge cycling. While under tension, the muscle may lengthen, shorten, or remain the same. Although the term contraction implies shortening, when referring to the muscular system, it means muscle fibers generating tension with the help of motor neurons (the terms twitch tension, twitch force, and fiber contraction are also used).

The final step involved in skeletal muscle contraction is?
The muscle cell relaxes and returns passively to its resting length
What are facts about a skeletal muscle cell?
A skeletal muscle cell is a cell of a skeletal muscle.
Which of cell type is specialized for contraction and generation of force?
The three types of muscle cells (cardiac, smooth and skeletal) fit this description.
Describe the events of muscle cell contraction?
6 steps in a muscle contraction
What is the advantage of having multiple nuclei in one skeletal muscle cell?
the ability to produce large amounts of the enzymes and structural proteins needed for contraction
What role do nerves play in skeletal contraction?
When you think about moving your arm, your brain sends a signal down a nerve cell telling that muscle to contract. -
Is Sketel Muscle an plant cell or a animal cell?
A skeletal muscle is an animal cell.
Which muscle tissue has several nuclei per cell?
Smooth muscle tissue
What organelle is found in large numbers in a skeletal muscle cell?
mitochondia is greater in number in skeletal muscle cells.
Contraction mechanism in a skeletal muscle cell?
ACH is released at the end-plate potential. ACH diffuses into the sarcolemma, attaches to the receptors in the motor end plate and causes a change in the ions permeability that creates graded depolarization of the end-plate potential. Basically, it attaches to the receptors in the motor-end plate and creates the beginning process of triggering muscle contractions.
What are the tissues in skeletal muscle?
Skeletal muscle is made up of individual components known as muscle fibers. These fibers are formed from the fusion of developmental myoblasts (a type of embryonic progenitor cell that gives rise to a muscle cell). The myofibers (muscle fiber) are long, cylindrical, multinucleated cells composed of actin and myosinmyofibrils repeated as a sarcomere, the basic functional unit of the cell and responsible for skeletal muscle's striated appearance and forming the basic machinery necessary for muscle contraction. The term muscle refers to multiple bundles of muscle fibers held together by connective tissue. Wikipedia dude ...
What is each skeletal muscle cell known as?
straited muscle
