Muscle Mechanics

Muscle mechanics refers to how muscles contract and produce movement in the body. Muscles are made up of fibers that work together. When a muscle receives a signal from the nervous system, it contracts by shortening, pulling on bones through tendons. This action creates movement at joints. Muscles operate in pairs; when one muscle contracts, its counterpart relaxes. Factors such as muscle length, speed of contraction, and energy sources affect strength and endurance. Understanding muscle mechanics helps us appreciate how our body performs everyday tasks, from walking to lifting objects.
