What type of movement occurs when the hamstring muscle contracts?
Flexion
What is difference between rigor mortis and heat stiffening?
Rigor mortis is brought on by the release of calcium from the decomposing cells. It causes the the cross links in the muscle cells to link. As ATP is need for the release of the cross links the body remains stiff. (no ATP as body is dead) Rigor passes within 36hrs. Heat stiffening is the shrinking of the muscles due to the coagulation of the muscle proteins. Think about frying beef, it shrinks. Heat stiffening lasts until the body begins to break down the muscles and only then will the body go flaccid. Rigor mortis doesn't occur.
Rigor mortis occurs at death due to a lack of?
Rigor mortis occurs at death due to the lack of adenosine triphosphate (ATP) in the muscles, which is needed for muscle contraction. When ATP production ceases, the muscles become stiff and rigid, leading to the characteristic stiffening of the body after death.
How does the body stiffening before death impact the process of dying?
The body stiffening before death, known as rigor mortis, is a natural process that occurs after death. It does not impact the process of dying itself, as it occurs after death has already occurred. Rigor mortis is a temporary condition that occurs as the muscles in the body stiffen due to chemical changes.
Ischemia occurs when the heart muscle?
regenerates
What is the typical pattern of an infantile spasm?
The typical pattern of an infantile spasm occurs soon after arousal from sleep, and involves a sudden bending forward and stiffening of the body, arms, and legs
Which type of fermentation is occurs in muscle cell?
yeast
What injury occurs when a muscle is over stretched?
CRAMPS
When fermentation occurs in muscle cells muscle fatigue is called by the production of?
Lactic acid builds up and causes muscle burn.
When does muscle relaxation occur?
Muscle relaxation occurs when the muscle fibers stop contracting and return to their resting state after being stimulated.
How relaxation in a skeletal muscle fiber occurs?
Relaxation of a skeletal muscle usually involves the Golgi tendon proprioceptors.
When a muscle contraction occurs?
your muscles moves, moving ligaments and tendons
