Document Summary

Mesenchyme develops into a body of hyaline cartilage; 2. Bony collar is laid down around a cartilage model; 5. Vascularization occurs as blood vessels enter the primary ossification center; 4. Osteoblasts deposit osteoid tissue thickening the bony collar; 3. Osteoclasts dissolve bone from the diaphysis" interior enlarging the marrow cavity: a growing bone in a child has only two areas of cartilage at the epiphysis. Except (acetylcholine binds to receptors in nmj connected to voltage-gated ion channels: all of the following are part of the excitation-coupling phase of skeletal muscle fibers. Length which can form the greatest number of cross bridges: which of the following is the correct order of steps for contraction of skeletal muscle fiber (assume hydrolysis of atp has just occurred)? (1. Myosin head changes shape and is extended into cocked position ; 2. Myosin flexes and tugs the thin filament along with it; 3.
