Why is the erector muscle classified as a tissue?
In biology, a tissue is just a group of cells that share the same origin and work together to do something. It's a level of organization. An erector muscle fulfills those requirements, so it can be considered a tissue.
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.
Are contractile proteins and motor proteins the same thing?
No, contractile proteins are involved in muscle contraction, while motor proteins are involved in cellular movement and transportation of organelles. Both types of proteins use ATP to produce movement, but they serve different functions in the body.
What Major function is to contract?
The major function of a muscle is to contract and generate force, which allows for movement, stability, and posture in the body. This contraction occurs when muscle fibers shorten and produce tension.
Myofibrils play a fundamental role in what?
Myofibrils play a fundamental role in muscle contraction and generating force in skeletal muscle. They are composed of thick and thin filaments that slide past each other during contraction, causing muscle fibers to shorten and produce movement.
What happens when the erector spinae contract concentrically?
Contraction of the erector spinae muscles can produce either unilateral flexion of the spine, or when they are used bilaterally they produce extension of the spine, which is more properly called the vertebral column.
What movement does contraction of the brachialis produce?
flexion of elbow
What type of movement does the contraction of an extensor produce?
It will be flexing.
What type of movement does the contraction of a Extensor produce?
The contraction of a flexor allows the arm or leg to bend
In a concentration contraction the muscles shorten to produce movement?
True.
What is the type of contraction in which the muscle fibers produce increased tension but does not shorten?
An isometric contraction builds tension but there is no joint movement.
What is a concentric contraction?
concentric contraction is atype of muscle contraction which the muscle shortens while genrating aforce The muscle shortens to produce movement. A muscle contraction in which shortening occurs.
Why is the erector muscle classified as a tissue?

What is a twitch contraction?
A twitch contraction is a single, brief contraction of a muscle fiber in response to a stimulus. It is the smallest unit of muscle contraction and is not strong enough to produce movement of a limb.
What do muscles produce?
Muscles provide movement, especially the skeletal muscles. The smooth muscles in our organs produce movement called peristalsis or tonic contraction which holds sphincters closed.
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 ist the process called that causes the cell to contract or shorten?
This process is called contraction. Muscles shorten or contract to produce movement.
