The major function of the pectoral girdle is mobility. What is the major function of the pelvic girdle? These two girdles attach differently to the axial skeleton. This form of attachment is related to their particular function in the body. How do these attachments differ?
While playing on her set, 10 year old sally falls and breaks her right leg. At the emergency room, the doctors tells her parents that the proximal end of the tibia where the epiphysis meets the diaphysis is fractured. The fracture is properly set and eventually heals. During a routine physical when she is 18, sally learns that her right leg is 2 cm shorter that her left, probably because of her accident. What might account for this difference?
How are the pectoral and pelvic girdles structurally different? and how is this difference reflected in their functions ?
