What is the fundamental functional muscle fiber's unit of contraction?
The smallest contractile unit of a muscle fiber is the sarcomere.It is composed of contractile myofilaments known as actin and myosin.
The movable part of a muscle is?
The sarcomere is the contractile unit of a muscle fiber.
What is a sacromere?
The sarcomere is the smallest contractile unit of muscle.
Smallest contractile unit individual muscle fibers?
sarcomere
What is a contractible unit of muscle?
Sarcomere
The smallest functional unit of the muscle fiber?
The smallest functional unit of a muscle fiber is the sarcomere. Sarcomeres are composed of actin and myosin filaments arranged in a repeating pattern, allowing for muscle contraction and relaxation to occur. They are responsible for the striated appearance of skeletal muscle under a microscope.
What is the smallest structure in a muscle?
Muscles always contract entirely i.e. every part of the muscle which contains myosin and actin (contractile proteins) is able to contract and does contract almost simultaneously.
What is the smallest individual unit of a contractile tissue called?
a cell
What is the basic unit of muscle?
muscle fiber
What is one of the functional units of a myofibril?
sarcomere
The smallest unit of textile material is called?
The smallest unit of textile material is a fiber. The length of a fiber is greater than the diameter.
What levels of organization is gound-up muscle?
Levels of organization of muscle ( in decreasing order)1. Muscle: Group of muscle fascicles, which work together to cause one specific movement.2. Fascicle: Bundle of muscle fibers3. Muscle fiber: Muscle cell: cylindrical cell of skeletal muscle. It has many nuclei, therefore it is called multinucleate.4. Myfibril: Contractile fibers found within a muscle cell. It has 100 - 1000's of muscle cells in each muscle fiber.5. Sarcomere: Structural and Functional unit of the muscle. It is the smallest unit of a muscle that is able to contract.6. Actin and myosin filaments: Filamentous proteins which can interact together to cause contraction.
