- A myofibril (also known as a muscle fibril) is a basic rod-like unit of a muscle cell.Muscles are composed of tubular cells called myocytes, known as muscle fibers in striated muscle, and these cells in turn contain many chains of myofibrils. Thin filaments consist primarily of the protein actin, coiled with nebulin filaments. 2  Actin, when polymerized into filaments, forms the ladder along which the myosin filaments climb to generate motion. 3  Thick filaments consist primarily of the protein myosin, held in place by titin filaments.

Elastic fiber Elastic fibers (or yellow fibers) are bundles of proteins (elastin) found in extracellular matrix of connective tissue and produced by fibroblasts and smooth muscle cells in arteries.These fibers can stretch up to 1.5 times their length, and snap back to their original length when relaxed.lastic tissue is classified as connective tissue proper. The elastic fiber is formed from the elastic microfibril (consisting of numerous proteins such as microfibrillar-associated glycoproteins, fibrillin, fibullin, and the elastin receptor) and amorphous elastin.

Skeletal muscle Muscle fibers are in turn composed of myofibrils. The myofibrils are composed of actin and myosin filaments, repeated in units called sarcomeres, the basic functional units of the muscle fiber.The sarcomere is responsible for the striated appearance of skeletal muscle, and forms the basic machinery necessary for muscle contraction.keletal muscle is made up of individual muscle cells or myocytes, known as muscle fibers. They are formed from the fusion of developmental myoblasts (a type of embryonic progenitor cell that gives rise to a muscle cell) in a process known as myogenesis.

Skeletal muscle Most skeletal muscles are attached to bones by bundles of collagen fibers known as tendons. A skeletal muscle refers to multiple bundles of cells called muscle fibers (fascicles). The fibres and muscles are surrounded by connective tissue layers called fasciae. Muscle fibres, or muscle cells, are formed from the fusion of developmental myoblasts in a process known as myogenesis.

- The term muscle refers to multiple bundles of muscle fibers called fascicles. All muscles also contain connective tissue arranged in layers of fasciae. Each muscle is enclosed in a layer of fascia; each fascicle is enclosed by a layer of fascia and each individual muscle fiber is also enclosed in a layer of fascia.t is one of three major muscle types, the others being cardiac muscle and smooth muscle.

What are muscles made of? Rating Newest Oldest. Best Answer: The muscles are made up of packages of stretchable fibre like material. Every fibre of the muscle is approximately forty millimeter in length and is made up of a number of very small strands which are known as fibrils. These fibres are extremely slender, so much so that one square centimeter of a muscle contains in it up to one million fibres. Each fibre is commanded by a nerve which makes it to contract. The number of fibres, contracting, determine the strength of muscles work. Muscle is mainly composed of muscle cells. Within the cells are myofibrils; myofibrils contain sarcomeres, which are composed of actin and myosin.

Elastic fiber Definition. noun, plural: elastic fibers. A type of fiber that is thick and yellowish, and composed primarily of elastin. It is distinguished from other connective tissue fibers for its great elasticity. It can stretch up to one and a half times their length then snap back to its original length when relaxed.

- In contrast, young open-grown giant sequoias taper markedly. The greatest known age of a giant sequoia is 3,200 years, determined from a stump count of rings (16). Calculations based on increment borings yield age estimates of 2,000 to 3,000 years for many living trees.iant sequoia seeds are well adapted for wind dispersal. They are light (average 200,000/kg [91,000/lb]), winged, and fall in still air at a rate of 1.2 to 1.8 m (4 to 6 ft) per second.

- Surrounding each muscle fiber (cell) is a delicate external lamina composed primarily of reticular fibers. This external lamina is produced by the muscle fiber and, when observed through the light microscope, cannot be distinguished from the cell membrane of the muscle fiber, the sarcolemma.

Muscle and Muscle Fibers Smooth muscle tissue is located in the walls of hollow structures such as blood vessels, the stomach, intestines, and the bladder. Smooth muscle fibers are usually involuntary, and they are non-striated (smooth). Smooth muscle tissue, like skeletal and cardiac muscle tissue, can undergo hypertrophy (growth).bjective: The objective of the muscle fiber test is to determine the fiber composition of the muscles being used for a particular exercise. Two test protocols are described: The Dr F. Hatield muscle fiber test and the Charles Poliquin muscle fiber test.
