Weaker contractions occur in muscles that are overly stretched because there is minimal thick and thin filament overlap for crossbridge formation. true or false

True

Explanation:

Muscle contraction. It refers to the physiological process during which the muscle, by sliding of the structures that compose it; It shortens or relaxes. Its functioning is closely related to the structure of the muscle fiber and the transmission of the electrical potential through the nerve pathways. The model that describes muscle contraction is known as a filament slip mechanism.

Small projections that originate on the sides of myosin filaments are called cross bridges, the interaction between these cross bridges and actin filaments causes contraction.

When there is an increase in the total mass of a muscle it is called muscular hypertrophy. When it decreases The process is called muscular atrophy.

When the frequency reaches a critical level, the successive contractions finally become so rapid that they merge with each other and the contraction of the entire muscle appears to be completely smooth and continuous so weaker contractions.

the correct answer is (

explanation:

oxygen = 21% of the atmosphere

nitrogen = 78%

carbon dioxide = 0.1%

argon =0.934%
