Other tissues in muscles are connective tissues, such as tendons that attach skeletal muscles to bones and sheaths of connective tissues that cover or line muscle tissues. Only muscle tissue per se, however, has cells with the ability to contract.

Having a broken bone can really restrict your activity. Bones are very hard, but they will break, or fracture, if enough force is applied to them. Fortunately, bones are highly active organs that can repair themselves if they break. Bones can also remodel themselves and grow. You'll learn how bones can do all of these things in this concept.

What are the advantages and disadvantages of external and internal forms of fertilization? Compare spermatogenesis and oogenesis as to timing of the processes and the number and type of cells finally produced. Why do mammalian eggs have a small concentration of yolk, while bird and reptile eggs have a large concentration of yolk?
