Muscle contraction is the generation of tension ... TMEM16A acts in smooth muscle cells as a critical pacemaker channel that enables the internal anal sphincter to contract rhythmically and ...

Calcium and ATP are cofactors (nonprotein components of enzymes) required for the contraction of muscle cells. ATP supplies the energy, as described above, but what does calcium do? Calcium is ...

Isotonic contractions – these occur when a muscle contracts and changes length and there are two types: Isotonic concentric contraction – this involves the muscle shortening. The origin and ...

Muscular contractions are defined as the change in the length of the muscle under contraction. Muscles contract in different ways to produce a range of movements: Isotonic contraction – involves ...

In a new study of mouse cells, scientists found that both the biochemical and mechanical effects of exercise may help injured ...

Human embryo at the 4-cell stage. Cell DNA appears in red and their actin cytoskeleton in blue. The cell on the right has just split its genome into two and is about to divide.

human embryo compaction is driven by the contraction of embryonic cells. Compaction problems are therefore due to faulty contractility in these cells, and not a lack of adhesion between them ...

The study of molecular mechanics and cellular motility. Cell motility, regulation of cell shape and the mechanism and regulation of muscle contraction. Our lab’s main interest is the study of ...
