(Check all that apply) ___a. pubis ____ b. rib _____ c. scapula _____ d. skull _____e. sternum Which of the following bones compose the os coxae? (Check all that apply.) ____a. coccyx ____ b. ileum ______c. ischium ______ d. pubis ______ e. sacrum The pectoral girdle consists of the scapula and clavicle, and the pelvic girdle consists of the os coxae. ___________ (True/False) You are a biomedical researcher who is interested in designing a drug to increase bone density. You have decided you can take one of two approaches (1) design a drug that stimulates bone to be built faster, or (2) design a drug that prevents bone from breaking down. To begin this process, you need to study the cells that would likely respond to either drug 1 or drug 2. What cells are these? a. _________(build bone) b. _________ (break down bone) What process must stop in order for the epiphysis plate to close? (That is, which layer of the plate must stop its development first) A forensic anthropologist identifies a bone as a left femur with epiphyses that are detached from the diathesis. Does this bone belong to a juvenile or an adult? Justify your answer. One effect of growth hormone (GH) is the stimulation of cartilage growth. Discuss how decreased GH production during development might impact a person's height.
