What else can I help you with?
Is this statement true or false Skeletal muscles always work in antagonistic pairs?
False. While many skeletal muscles do work in antagonistic pairs (e.g. biceps and triceps), not all skeletal muscles function this way. Some skeletal muscles work alone or in synergy with other muscles to produce movement.
What are the key differences between skeletal and cardiac muscle in terms of their structure and function?
Skeletal muscles are attached to bones and help with movement, while cardiac muscles are found in the heart and help pump blood. Structurally, skeletal muscles have long, cylindrical fibers with multiple nuclei, while cardiac muscles have branching fibers with a single nucleus. Functionally, skeletal muscles are under voluntary control, while cardiac muscles contract involuntarily.
In some reflex actions skeletal muscles contract without the involvement of what?
In some reflex actions, skeletal muscles contract without the involvement of conscious thought or decision-making processes from the brain. These reflex actions are controlled by the spinal cord and are known as spinal reflexes.
Muscle under voluntary control are known as?
skeletal muscles or voluntary muscles
Bodily movement produced by skeletal muscles is called?
Skeletal muscles are attached to the bones by tough cords called tendons. When nerve signals are sent from the brain and spinal cord, these muscles contract to produce movement.
What muscle skeletal muscles do to move?
Skeletal muscles rely on contractions to move the bone they are attached to so it is contract and relax
What proteins help contraction of skeletal muscles?
Actin and myosin cause muscles to contract.
Which muscle type can voluntarily contract and relax?
Skeletal muscles .
What additional skeletal muscles are utilized in an ERV activity?
abdominal-wall muscles and the internal intercostal muscles contract.
Without what can skeletal muscles contract in some reflex actions?
the brain.
Skeletal muscles always work in antagonistic pairs.?
false....
Which muscle type is voluntary in action?
The skeletal muscle is the only type of muscle which is voluntary.
What controls the skeletal and smooth muscles by telling them to either contract or relax?
CNS
What conscious decision to contract a muscle group or initiate a movement?
Skeletal (or striated) muscles
What muscles are the muscles that move bones?
These muscles are called "skeletal muscles".
What are the following types of muscles are striated?
skeletal and cardiac muscle are striated
Does skeletal muscles move limbs and produce smiles?
Yes, skeletal muscles are responsible for the movement of limbs in the body. They contain muscle fibers that contract and relax, causing the bones they are attached to move. Skeletal muscles also play a role in producing smiles, as they assist in the movement of the muscles in the face that create facial expressions.
