Gross Anatomy of Bones. The largest part of any long bone is the long cylindrical middle, called the diaphysis. Every long bone is capped with wide areas on each end which are called epiphyses. A long bone has two parts: the diaphysis and the epiphysis. Finally, at the end of a long bone is a region known as an epiphysis, which exhibits a cancellous internal structure and comprises the bony substructure of the joint surface.

Prior to this, she wrote curriculum and business papers in four different languages. The different structural layers of a flat bone include: Periosteum. The bones typically consist of a long shaft called the diaphysis, and two wider extremities on the ends called epiphyses. The skeletal system is composed of bones and cartilage connected by ligaments to form a framework for the rest of the body tissues. Between the ephiphysis cap and the long shaft of the diaphysis is a wide section of bone called the metaphysis. As seen in the image below, compact bone forms the cortex, or hard outer shell of most bones in the body. Tags: Question 7 . An easy way to remember the axial and appendicular skeleton is the ‘Law of the ones and twos’ – If the body only has one of the bones such as the skull then it’s part of the axial skeleton. The diaphysis also has small holes for blood vessels that carry nutrients to the compact bone cells.
