Sarcomere diagram

When a muscle contracts in our body the distance reduces between the Z discs. The central region of the A zone (H zone), contains only thick filaments (myosin), and became short during contraction. Draw and label a diagram to show the structure of a sarcomere, including Z lines, actin filaments, myosin filaments with heads, and the resultant light and dark bands. 1 No other terms for parts of the sarcomere are expected.Sarcomere - Definition, Structure, Function and Quiz | Biology DictionaryImageQuiz: Muscle sarcomere structure Draw your own diagram of two sarcomeres. The first should be of a relaxed muscle. The second should be of a contracted muscle.

When drawing a diagram of a sarcomere it is important to remember the following conventions: The myosin filaments are the thick filaments and should be represented as being thicker than the actin filaments The myosin filaments should include protruding heads (myosin heads form cross-bridge attachments with actin) Start studying Sarcomere. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Each sarcomere divides into different lines, bands, and zone: “I” and “A” bands, “M” and “Z” lines, and the “H” zone. – Z-lines define the boundaries of each sarcomere. – The M-line runs down the center of the sarcomere, through the middle of the myosin filaments. – The I-band is the region containing only thin filaments.
