- Define calcaneal tendonarrow_forwardAt first, Donnie’s wife accused her once-active 25-year-old husbandof trying to get out of housework by constantly complaining aboutpain and stiffness in his lower back. But over the next 5 months, thepain and stiffness increased and seemed to be spreading up his vertebral column. The family doctor referred Donnie to a rheumatologist,who diagnosed ankylosing spondylitis (AS). AS, a chronic inflammation of joints at points where ligaments, tendons, and joint capsuleinsert into bone, causes fibrosis (the development of scar tissue), ossification, and fusion of joints. Combine your knowledge about bonegrowth, repair, and anatomy from chapters 6 and 7 and joint structureand function from this chapter to identify the category of joints primarily affected by AS, and explain how chronic inflammation ofDonnie’s joints led to their fusion.arrow_forwardIf the primary action of digastric is to elevate the hyoid bone, explain its reverse muscle action (RMA)arrow_forward
