The gross physiology of skeletal muscle
Items covered in this animation:
- This animation describes how the basic building
blocks of a muscle fit together. It shows the myofibrils bunched
together with the lattice type network of the sarcoplasmic reticulum wrapped
around them. It also shows how the network of transverse tubules lace
their way through the structure and how they are continuous with the outer
membrane of the myofiber. Finally the aniomation goes on to describe the
connective tissue that holds the muscles together called the fascia. This exists on three major levels with the Epimysium wrapping around whole muscles, the perimysium enveloping bundles of fibers called fasicles, and finally the endomysium which surrounds each individual fiber.
