What happens to the length of a muscle when it contracts?
When a muscle contracts, it shortens in length.
When a muscle contracts, it pulls with what force?
When a muscle contracts, it pulls with a force generated by the muscle fibers contracting and shortening.
What does it mean when a muscle contracts and how does this process occur in the human body?
When a muscle contracts, it shortens and tightens, causing movement. This process occurs in the human body when signals from the brain travel through nerves to the muscle, triggering the release of calcium ions. These ions bind to proteins in the muscle cells, causing them to slide past each other and contract. This contraction allows the muscle to generate force and move the body.
What physiological process leads to hypertrophy of muscles, and how does an increase in this process contribute to muscle growth?
Hypertrophy of muscles is caused by an increase in protein synthesis, which is the process of building new proteins in the muscle cells. When protein synthesis is increased, more muscle proteins are created, leading to muscle growth. This process is typically stimulated by factors such as resistance training and adequate nutrition, which provide the necessary stimulus and building blocks for muscle growth.
If a muscle contracts and its fibers shorten is the contraction isometric?
No! It is isotonic. But if the muscle contracts and the fibers do not shorten because the load is greater than the force applied to it, it is isometric.
Which muscle contracts aiding the process of breathing?
The diaphragm - a sheet of muscle across the rib-cage just under the lungs.
What does a muscle become when it contracts?
A muscle becomes shorter when it contracts.
What happens to the length of a muscle when it contracts?
When a muscle contracts, it shortens in length.
When a muscle contracts how does its form change?
A muscle that contracts shortens whereas a muscle that relaxes lengthens.
When a muscle contracts, it pulls with what force?
When a muscle contracts, it pulls with a force generated by the muscle fibers contracting and shortening.

What does within the muscle means?
"Within the muscle" typically refers to processes, activities, or conditions occurring inside muscle tissue. This can involve physiological functions like contraction and relaxation, metabolic processes, or the presence of injuries and diseases. It emphasizes the internal environment and dynamics of muscle fibers and cells.
When one muscle contracts what happens to the opposing muscle?
When one muscle in a pair contracts the other expands.
WHEN A MUSCLE CONTRACTS DOES IT BECOME SHORTER AND FATTER?
Yes, when a muscle contracts, it becomes shorter and thicker. This occurs because the muscle fibers, made up of actin and myosin filaments, slide past each other, causing the overall length of the muscle to decrease while increasing its girth. This process allows the muscle to generate force and perform movements.
