Myofibril
myofibril
muscle fiber, myofibril, myofilaments, sarcomere
The smaller fiber in a muscle fiber is called a myofibril. A band of tissue that connects bone to bone is called a ligament.
Muscle, fasicle, muscle fiber, myofibril, myofilament
sacomeres are a single unit of a muscle fiber multiple sacomeres make up a myofibril
The organization of a skeletal muscle from smallest to largest is as follows: myofilaments > myofibrils > muscle fiber > fascicle > muscle
A muscle organ is made up of several muscle fibers, which are the individual cells that contract to produce movement. Each muscle fiber contains myofibrils, which are long, thread-like structures that run the length of the fiber and are responsible for contraction. Myofibrils are composed of myofilaments, the smallest units, which include actin (thin filaments) and myosin (thick filaments) that interact to facilitate muscle contraction. Together, these structures create the hierarchy of muscle organization from the whole muscle down to the molecular level.
A whole muscle is the whole muscle while a muscle fiber is part of a muscle. I'm not sure if I'm correct though, so check with some different sources.
Short Answer:A myofibril is smaller than a myofiber (muscle fiber).Long Answer:Skeletal Muscle Hierarchy:Muscle OrganPerimysium = white fibrous connective tissue & areolar connective tissue that surrounds each fascicleFascicle = bundle of skeletal muscle fibersEndomysium = areolar connective tissue that surrounds each muscle fiberMuscle Fiber ( Myofiber) = a muscle cellMyofibrils = contractile protein organellesMyofilaments = contractile proteins composed of:thick filaments = made of myosinthin filaments = made of actin
The largest skeletal muscle connective tissues are fascicles, which are bundles of fibers, which are made of myofibrils, which consist of myofilaments.
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.
