What 2 lines would you find a sacromere between
Z- lines
A sarcomere is the basic functional unit of a muscle fiber, and it is the region that is responsible for muscle contraction. A sarcomere is located between two Z lines, also known as Z discs. These Z lines are perpendicular to the myofibrils (contractile filaments within a muscle fiber) and represent the boundaries of the sarcomere. The contractile proteins actin and myosin are arranged in a specific pattern within the sarcomere, which allows for muscle contraction. The sarcomere shortens during muscle contraction, resulting in movement of the muscle.
