Why are skeletal muscle fibers unusual?
The skeletal muscle, or striated muscle, is the muscle attached to the skeleton. Most skeletal muscles are attached to bones by bundles of collagen fibers known as tendons. The contraction of skeletal muscle is under voluntary control.
Skeletal muscle twitch differs from a tetanic contraction in that?
the muscle twitch is a brief and "jerky" movement, while the tetanic contraction is prolonged and continuous
What components of nerves are involved in skeletal muscle movement?
The motor neurons are responsible in skeletal muscle movement.
Does a skeletal muscle fiber contain many nuclei?
Skeletal muscle fibers contain numerous nuclei. This is used to produce large amounts of the enzymes and structural proteins needed for muscle contraction.
Does the trachea have skeletal muscle?
No, it doesn't have skeletal muscle,, only smooth muscle..
In addition to myosin what other protein is involved in skeletal muscle contraction?
Myosin acts with Actin during muscle contraction
What system are involved in a muscle contraction?
skeletal system, Digestive and Nervous system.
Which protein inhibits skeletal muscle contraction?
Tropomyosin;calcium ions
The final step involved in skeletal muscle contraction is?
The muscle cell relaxes and returns passively to its resting length
What type of muscle is capable of rapid contraction and causes skeletal movement?
Skeletal or voluntary muscle is capable of rapid contraction and is responsible for skeletal movement.
Does stretch have any effect on skeletal muscle contraction?
yes skeletal muscle stretch by means of contraction.
The first step toward generating a skeletal muscle contraction is The first step toward generating a skeletal muscle contraction is?
stimulation of the muscle by a nerve ending.
Which protein inhibits skeletal muscle contraction and what ion removes the inhibition?
Tropomyosin; calcium ions
What factors affect muscle contraction?
the degree of muscle stretch is affect the strength or force of skeletal muscle contraction
Do skeletal muscles have involuntary muscle?
The skeletal muscles do have the involuntary muscle because they help it in the contraction process.
What band shortens during skeletal muscle contraction?
during skeletal muscle contraction ,I band and H zone shortens. Sarcomeres
True or false When the contraction of a skeletal muscle is studied in the laboratory by applying an electrical charge to the muscle the contraction is called a muscle twitch.?
true
