A) Which clue would tell Stefan which scapular surface was anterior and which was posterior? What is the name of the shallow, oval socket of the scapula that Stefan placed next to the humerus?
- The medial border of the scapula is the longest of the three borders, and extends from the
superior to the inferior angle. It is arched, intermediate in thickness between the superior
and the axillary borders. This border presents an anterior and a posterior lip, and an
intermediate narrow area
B) Which bone is Stefan referring to as the “collarbone”?.
-The clavicle or collarbone is a long bone that serves as a strut between the scapula and the
C) Which surface markings could Stefan use to distinguish the right humerus from the left?
- In order to distinguish right from left, first orient the bones so that the rounded head is superior (up) and pointing medially (toward the body's midline). Then you will need to determine the anterior vs. posterior side. On the femur, look for the patellar surface, which is anterior
D) Why would Stefan think that an enlarged right deltoid tuberosity might indicate right
- Because the deltoid tuberosity on the right humerus was somewhat larger than on the left. Deltoid tuberosity is the site of attachment for the deltoid muscle
E) What is the location of the pubic symphysis Stefan refers to in the story?
- The pubic symphysis or symphysis pubis is the midline cartilaginous joint uniting the superior of the left and right pubic bones. It is located anterior to the urinary bladder and superior to the external genitalia; for females it is above the vulva and for males it is above the penis
F) Which adaptation would have taken place in the pubic symphysis of the female skeleton during the later stages of her pregnancy in preparation for the birthing process?
