Myofibrils are thread like structures found in muscle fiber composed of bundles of myofilaments.

Chromosomes are the threadlike structures that are made up of proteins and DNA. Chromosomes are found in the nucleus of the cell.
The threadlike fibers in the cell membrane are called actin filaments. They are part of the cytoskeleton and play a key role in maintaining cell shape, cell movement, and cell division. Actin filaments are made up of actin proteins that polymerize to form long, thin fibers.
Chromosomes are the threadlike structures that are made up of proteins and DNA. Chromosomes are found in the nucleus of the cell.
Chromatin or chromatin threads are the threadlike structures that are found in the nucleus. They contain DNA which is a genetic material.

Type II (fast-twitch) muscle fibers are found in higher proportion in weight lifters. These fibers generate more force and are associated with explosive movements and short bursts of intense activity.

Thin threadlike structures found within the cytoplasm of a cell are called microfilaments. These filaments play a key role in cell movement, shape maintenance, and intracellular transport.
