Topic: Specialized Cell Muscle Cell. Sarcomeres are contractile units of skeletal muscle that divide into “I” and “A” bands, “M” and “Z” lines, and the “H” zone. The sarcomere is the basic contractile unit of skeletal muscle. It is made of thick and thin filaments.
band cell. ( band sel) Any cell of the granulocytic (leukocytic) series that has a nucleus that could be described as a curved or coiled band, no matter how marked the indentation, if it does not completely segment the nucleus into lobes connected by a filament. Synonym (s): stab cell, staff cell.
The presence of band (immature) neutrophils in circulation is termed a regenerative left shift and indicates a bone marrow response to an inflammatory stimulus. When band cells outnumber mature neutrophils in the peripheral blood, the condition is referred to as a degenerative left shift.
Feb 20, 2018 · Tertiary (gelatinase) granules are found at the band cell stage. Finally, secretory vesicles are detected only in mature neutrophils (Figure (Figure2). 2 ). These granules store an arsenal of antimicrobial enzymes, including elastase, myeloperoxidase, cathelicidins, defensins, and matrix metalloproteinases, which are used to destroy invading ...

Mar 19, 2024 · The A band (anisotropic band) is the dark band of the sarcomere which contains the entirety of the myosin (thick) filaments and the parts of the actin (thin) filaments that overlap with the myosin filaments at either end.
In solid-state physics, the electronic band structure (or simply band structure) of a solid describes the range of energy levels that electrons may have within it, as well as the ranges of energy that they may not have (called band gaps or forbidden bands).
