What else can I help you with?
Skeletal muscles need nerve stimulation for contraction to occur?
Yes, nerve stimulation is necessary for skeletal muscles to contract. This stimulation causes an action potential to travel down the motor neuron, leading to the release of acetylcholine at the neuromuscular junction, which triggers muscle contraction by causing calcium release in the muscle fiber. Without this nerve input, skeletal muscles would not be able to contract voluntarily.
What muscle can contract without the need for the nervous stimulation?
Smooth & cardiac muscle.
Does glycerinated skeletal muscle fibers need ATP in order to contract?
true
Does glycerinated skeletal muscle fibers nee ATP in order to contract?
no, they need ATP
Does glycerinated skeletal muscle fibers need calcium in order to contract?
Yes, glycerinated skeletal muscle fibers still require calcium in order to contract. The glycerination process maintains the basic structure of the muscle fibers but removes cellular components, allowing for the fibers to contract in response to calcium in a controlled laboratory setting.
How does the shape of a cardiac muscle help it do its job?
because of it's shape the skeletal muscle can contract much easier.
What organs are needed to make the muscular system work?
You need your brain to send signals to a skeletal muscle telling it to contract.
What is the correct definition for voluntary muscle?
Voluntary (also known as) skeletal muscles are used to create movement, by applying force to bones and joints; via contraction. They generally contract voluntarily (via somatic nerve stimulation), although they can contract involuntarily through reflexes.muscular system Consists of all the muscles in the body, especially the ones that help you move. skeletal muscle Voluntary muscle that is attached to bones of the skeleton and helps the body move. smooth muscle Involuntary muscle that is found in the walls of internal organs, such as the stomach.
Why do skeletal muscle cells need to be physically connected to the outside environment?
Skeletal muscle cells need to be physically connected to the outside environment to receive signals from the nervous system and to contract in response to those signals. The physical connection allows for the exchange of nutrients, waste removal, and the delivery of oxygen to the muscle cells. Additionally, the connection allows for the removal of heat generated during muscle contractions.
How does the appearance of smooth muscle differ from that of skeletal muscle when viewed with a microscope?
i need the same answer...-.-
What are muscles skeletal cardiac and smooth?
smooth muscle is used in a train of thought (brain is need in the act) cardiac muscle can be found in the heart skeletal muscle moves your bones
What are myogenic cells?
Myogenic cells are muscle precursor cells that have the ability to differentiate into muscle cells. They play a crucial role in muscle development, growth, and repair. Myogenic cells are typically found in skeletal muscle tissue.
