Which is smaller a myofibril or a myofiber?
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
Which would you see only in the relaxed electron micrographs of a relaxed skeletal and muscle fiber and a fully contracted muscle fiber?
This question is confusing. Are you asking if you see only a relaxed muscle fiber in EMs? Yes, you would only see that, not a contracted muscle fiber. The preparation could only be of a relaxed fiber.
