Muscular system
/mʌskjʌlɝ/ /sɪstʌm/
1. [noun] the muscular system is an organ system consisting of skeletal, smooth and cardiac muscles. It permits movement of the body, maintains posture, and circulates blood throughout the body. The muscular system in vertebrates is controlled through the nervous system, although some muscles can be completely autonomous. Together with the skeletal system it forms the musculoskeletal system, which is responsible for movement of the human body
Frequently Asked Questions
How do intrinsic foot muscles compare to muscles higher up in the leg when stabilizing the foot during walking?
Intrinsic foot muscles, located entirely in the foot, help maintain arches and balance independently while extrinsic muscles in the leg control larger movements. Both sets work together during everyday activities such as walking and running.
In what ways does the strength of foot muscles contribute to everyday stability during common foot activities?
Strong foot muscles support arches, distribute weight evenly, and maintain balance. This muscular support is crucial during activities like standing, walking, or shifting positions, which can prevent discomfort and improve overall stability.
How is the proper function of the foot's muscular system different from a bone problem in affecting foot movement?
Issues with the foot's muscular system can lead to imbalance and misalignment, whereas bone problems generally cause sharp pain. Understanding the role of muscles helps clarify that some movement irregularities are due to support systems rather than structural damage.
