What type of joint movement occurs when a muscle moves a limb toward the mid line of the body?
Abduction is when a body part moves away from the midline.
What is the busiest muscle in the body?
It's true its the muscle that moves your eyes :)
What muscle moves the testes towards the body?
The abdomen.
During what process does the cardiac sphincter open involuntarily?
the cardiac sphincter opens involuntarily during peristalsis, which is the process of wavelike muscle contractions of the alimentary tract that moves food along the oesophagus down to the stomach. :)
What is an asophagus?
an asophagus is the muscle in your throat that moves the food down when you swallow.
What part of the muscle moves the least during the contraction?
The Origin
In an isotonic contraction the muscle does what?
Changes in length and moves the "load"
What are the two muscle movement?
Pulling and contracting is how a muscle moves the bones ....
When a muscle contraction occurs?
your muscles moves, moving ligaments and tendons
What is the involuntary muscle contraction that moves through the digestive system?
Peristalsis
Which kind of muscles move bones?
Smooth muscle is responsible for the contraction that moves limbs.
What does oesophagus do during digestion?
It takes food from the throat and pushes it down through the neck, and into the stomach. It moves food by waves of muscle contraction called peristalsis.
Five golden rules of gross skeletal muscle activity?
1. All muscles cross at least one joint. 2. Typically, the bulk of muscle lies proximal to the joint crossed. 3. During contraction, the muscle insertion moves toward the origin. 4. All muscles have at least two attachments (origin and insertion). 5. Muscles always pull, they never push.
Where does the muscle attach to the bone?
Where a muscle attaches to a bone is at the origin and insertion points. The origin is the immovable (or slightly moveable) attachment point and the the insertion is the movable attachment point. During contraction the insertion moves towards the origin. HOW a muscle attaches to a bone is through tendons.
Cool dense air moves during the night from the land toward water as?
Cool, dense air moves during night from the land toward water as = the answer is LAND BREEZE
What is the change in appperence of a myofibril during contraction with the I band?
In skeletal muscle contraction, the thin filaments of the sarcomere slide toward the M line, in between the thick filaments. This is called the sliding filament theory. The width of the A zone stays the same, but the Z lines move closer together. As the sarcomeres shorten and appear closer together, the muscle pulls together, producing tension that moves whatever it is attached to.Contraction is an active process; relaxation and return to resting length is entirely passive.
What factors inhibit muscle contraction?
One of the main things that will inhibit muscle contraction is the build up of lactic acid during aerobic exercise. Lactic acid will inhibit the bodys ability to break ATP down into ADP and therefore restrict the amount of useable energy available to the muscle.
