a myofilament would likely be found in what tissue? - muscle tissue a soft callus during bone fracture is made of - fibrocartilage adhering junctions - cement cells together albinism - Absence of pigment in the skin, hair, and eyes anatomical position - palms face forward, feet are flat on the floor, body is upright, thumbs point away from the body anatomy - The study of body structure appositional growth - increase in bone thickness atrophy - shrinkage of tissue by cell size or number ...

Myocyte Muscle cell Sarcolemma Plasma membrane of myocyte Sarcoplasm Cytoplasm of myocyte Myofibril Tightly packed filament bundles found within skeletal muscle fibers. Contractional unit of a muscle cell. Sarcoplasmic reticulum Site of calcium storage in a muscle cell. Surrounds the myofibrils Transverse tubules (T-tubule) Inward extensions of the sarcolemma that dive into the muscle fiber and surround each myofibril to form a tunnel-like network within the muscle fiber Terminal cisternae...
