What else can I help you with?
What movement occurs when the subscapularis contracts concentrically?
When the subscapularis muscle contracts concentrically, it performs internal rotation of the shoulder joint. This movement involves rotating the arm inward toward the midline of the body.
What muscle concentrically contracts when descending stairs?
Quads
Which muscle concentrically accelerates dorsiflexion?
Anterior tibialis
What muscle is the fascicles concentrically arranged around an opening?
Orbicularis
What movement does the arm make when the triceps muscle contract?
The biceps muscle relaxes!!!!!=)
What is the muscle's role in the body?
to contract to cause movement.
What kind of cells in your body can contract?
Muscle cells contract, causing movement and our heartbeat.
What are the only things a muscle can do?
A pull is the only action a muscle can perform.
What cells expand and contract to move the body.?
Muscle cells
Why do muscles shorten when they contract?
Muscles shorten when they contract because the muscle fibers within the muscle bundle slide past each other, causing the muscle to contract and pull on the attached bones, resulting in movement.
What is transversus in frog?
In frogs, the transversus abdominis muscle is a thin, flat muscle located in the abdominal region. It runs horizontally across the abdomen and helps with trunk flexion and compression of the abdominal viscera. It is part of the muscle group responsible for supporting and stabilizing the frog's body during movement.
Give examples for concentric and eccentric muscle contractions in gait cycle?
while kicking a football, the Quadriceps muscle contracts concentrically to straighten the knee and the Hamstrings contract eccentrically to decelerate the motion of the lower limb.In concentric muscle contraction muscle length decreases along with contraction of the fibres while in eccentric muscle contraction the muscle length increases.Dr Santosh
