Myomeres are blocks of skeletal muscle tissue arranged in sequence, commonly found in aquatic chordates. Myomeres are separated from adjacent myomeres by connective fascia (myosepta) and most easily seen in larval fishes or in the olm. Myomere counts are sometimes used for identifying specimens, since their number corresponds to the number of ...

These muscle segments, known as myomeres, consist of relatively short fibres that insert into septa of connective tissue, the myocommata, between the adjacent myomeres. There is only a rudimentary axial skeleton and no appendicular skeleton, so there are no limb muscles. The eyes of cyclostomes are degenerate structures, and the… Read More

Myomeres are the segmented paired muscular blocks that extend through the trunk and tail. Alternating contraction of the musculature of the right and left sides of the body exerts forces on the notochord, noted earlier as a laterally flexible rod, that allow the side-to-side locomotory movements characteristic of less derived chordates and ...

Mar 1, 2019 · Fish axial muscle consists of a series of W-shaped muscle blocks, called myomeres, that are composed primarily of multinucleated contractile muscle cells (myofibres) gathered together by an intricate network of connective tissue that transmits forces generated by myofibre contraction to the axial skeleton.

Dec 1, 1999 · An architectural analysis is offered of the trunk muscles in fish, which are arranged in a longitudinal series of geometrically complex myomeres. The myomeres are separated by myosepta, collagenous sheets with complex fibre patterns.

Mar 18, 2020 · Each segment, or sheet, of muscles is called a myomere or myotome and is separated from its neighbor by a sheet of connective tissue. Other sheets of connective tissue, called septa (pl =septum) occur along the vertical midline of the body, separating the muscles of the left and right sides of the body.

Mar 7, 2025 · These muscle segments, known as myomeres, consist of relatively short fibres that insert into septa of connective tissue, the myocommata, between the adjacent myomeres. There is only a rudimentary axial skeleton and no appendicular skeleton, so there are no limb muscles.

Myomeres are segmented blocks of skeletal muscle found in the bodies of certain animals, particularly in the phylum Chordata. These muscle segments are arranged in a zigzag pattern and are crucial for locomotion, especially in aquatic organisms, allowing …

An architectural analysis is offered of the trunk muscles in fish, which are arranged in a longitudinal series of geometrically complex myomeres. The myomeres are separated by myosepta, collagenous sheets with complex fibre patterns. The muscle fibres in the myomeres are also arranged in complex thr …

Nov 1, 2023 · Skeletal muscle is constituted by myomeres, segmented by myosepta. Each myomer is composed by myofibers, which are formed by myofibrils. Myofibrils correspond to the set of myofilaments, such as myosin and actin proteins.
