1. How is the contraction of a skeletal muscle cell different than the contraction of a smooth muscle cell? How does this aid in each muscle cell's function? 2. What is the purpose of myoglobin in slow-twitch muscle fibers? Why is there more myoglobin in slow-twitch muscle fibers than in fast-twitch fibers? 3. What is the purpose of gap junctions in cardiac muscle cells and some smooth muscle cells?

During the excitation phase of the skeletal muscle cell contraction, the following occurs: 1) the muscle fiber develops tension and shortens 2) the muscle fiber relaxes and returns to its original length 3) nerve action potentials lead to muscle action potentials A growing long bone in a child has only two types of cartilage at the epiphysis. These two areas are 1) elastic cartilage and epiphyseal plate 2) epiphyseal plate and epiphyseal line 3) primary and secondary ossification centers 4)...
