I. Urogenital system:
●pp. 199-207: Read, follow directions and answer questions. We will look more closely at
the human reproductive system in a few weeks.
-How is the urethra different in the male and female?
-Why do female pigs have a uterine horn and human females have a uterus?
●p. 222: Read and use diagram to locate the different structures of a sheep kidney. You
may not be able to see all the structures, but be able to identify the region where you would
find them.
-What is the major function of the kidneys?
II. Review:
●p. 214: Answer questions 1-14, 17-18.
III. Musculoskeletal system:
●p. 249: Read introduction and review Fig. 19.1.
●pp. 250-251: Use the cow femur in order to locate the long bone structures.
-You will not be able to see the red marrow on cow femur, but may have noticed it when
you cut through the pelvic bone on your fetal pigs.
-Besides the yellow marrow in the center of the bone, what is the rest of the material in the
center cavity (medullary cavity) of the cow femur?
●pp. 254-255: Be able to identify all of the bones listed in the key terms using the
articulated skeleton in the lab. You will already know more than you think, so focus on the
bones that you are unfamiliar with.
●pp. 255-257: Use the muscle model to locate all of the muscles listed in the key terms.
●pp. 258-259 (STOP at isometric and isotonic contractions): Read and answer questions.
●p. C61: Use the materials in chapter 19 to fill in the table on C61.
IV. Review:
●p. 262: Answer questions 2, 4, 5, 7, 12-15
