Sarcomere

sarcomere

[′sär·kə‚mir] (histology) One of the segments defined by Z disks in a skeletal muscle fibril.

Sarcomere

a muscle-fiber segment between two dark Z bands that is the main recurring structural unit of myofibrils. Each sarcomere includes a single dark anisotropic A band and two light isotropic I disks. In the middle of each sarcomere is a narrow light H band containing a dark central M band.

sarcomere

[sahr´ko-mēr] the contractile unit of a myofibril; sarcomeres are repeating units, delimited by the Z bands along the length of the myofibril.

Thick and thin filaments are organized into contractile units called sarcomeres. A sarcomere extends from one Z line to the next and represents the fundamental unit of muscle contraction. From Copstead, 1995.

sar·co·mere

(sar'kō-mēr), The segment of a myofibril between two adjacent Z lines, representing the functional unit of striated muscle. [sarco- + G. meros, part]

sarcomere

The structural unit of a striped muscle fibre (myofibril).

Fig. 273 Sarcomere . Muscle fibrils consist of alternating groups of the thick and thin filaments (dark and light bands), the distance between two Z-membranes being termed a ‘sarcomere’.

sarcomere

that part of the muscle fibre which is contained between two Z-MEMBRANES, and is the contractile element of the fibre.
