What else can I help you with?
What factors affect muscle contraction?
the degree of muscle stretch is affect the strength or force of skeletal muscle contraction
Which fibers in the skeletal muscle are stimulated only by the degree of stretch?
Muscle spindles are the fibers in skeletal muscles that are stimulated by the degree of stretch. These specialized sensory organs detect changes in muscle length and contribute to the stretch reflex, helping to maintain posture and control muscle contraction.
How does the contraction of the I band contribute to the overall function of skeletal muscle?
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.
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.
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.
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
In addition to myosin what other protein is involved in skeletal muscle contraction?
Myosin acts with Actin during muscle contraction
What is Skeletal muscle tonus?
The state of activity or tension of a muscle beyond that related to its physical properties, that is, its active resistance to stretch. In skeletal muscle, tonus is dependent upon efferent innervation. A constant state of slight tension that serves to maintain the muscle in a state of readiness is known as tonus.
When the contraction of a skeletal muscle is studied in the laboratory by applying an electrical charge to the muscle the analysis of the contraction is called a muscle twitch?
A muscle twitch refers to a single, quick contraction and relaxation of a skeletal muscle in response to an electrical stimulus. In a laboratory setting, researchers can analyze the characteristics of the twitch, such as its duration, force, and the time between the stimulus and contraction (latency). This helps in understanding muscle physiology and the mechanisms of muscle contraction.
Basic unit of contraction in skeletal and cardiac muscle?
The Sarcomere
