The site of calcium regulation differs
Smooth muscle, skeletal muscle, and cardiac muscle all contract in response to signals from the nervous system or hormones. However, the contraction mechanism of smooth muscle is different from that of skeletal and cardiac muscle. Smooth muscle contracts more slowly and can sustain contractions for longer periods of time compared to skeletal and cardiac muscle. Additionally, smooth muscle does not have striations like skeletal and cardiac muscle, which gives it a more uniform appearance.
The contraction of the I band in skeletal muscle helps to shorten the muscle fibers, allowing for movement and muscle contraction. This contributes to the overall function of skeletal muscle by enabling the muscle to generate force and produce movement.
Skeletal or voluntary muscle is capable of rapid contraction and is responsible for skeletal movement.
yes skeletal muscle stretch by means of contraction.
stimulation of the muscle by a nerve ending.
the degree of muscle stretch is affect the strength or force of skeletal muscle contraction
Skeletal muscle cells are very thin, and lean. They are designed for contraction and expansion.
The heart muscle is different from smooth and skeletal muscles because it does not require a nerve to cause it to contract. The heart has it's own built in conduction system that cause's the automatic contraction and relaxation that is required for circulation. Smooth and Skeletal muscle whether it uses voluntary or involuntary muscle contraction all have innervation to cause the contraction. Sara, RN
The skeletal muscles do have the involuntary muscle because they help it in the contraction process.
during skeletal muscle contraction ,I band and H zone shortens. Sarcomeres

The chemical used at the junction with a skeletal muscle is acetylcholine (ACh). It is released from the motor neuron at the neuromuscular junction and binds to receptors on the muscle fiber's membrane, triggering muscle contraction. This process is essential for voluntary movement and is part of the overall neuromuscular signaling mechanism.
