LEARNING ACTIVITY 4 PN105 – HUMAN ANATOMY & PHYSIOLOGY TO TEACH TO GUIDE TO LEARN N AME : K YLIE OKRAINETZ C OURSE #: PN105 – Anatomy & Physiology D ATE : N OVEMBER 18, 2023 F INAL M ARK : /40 Label Label the following diagram 1. Epiphysis 2. Diaphysis- shaft, hollow tube of hard compact bone, strong structure but light to permit easy movement. The long length of the bone. 3. Epiphysis-ends of a long bone. Red bone marrow fills in the small spaces in the spongy bone inside the epiphysis (but yellow marrow may appear with age in a person). 4. Periosteum – strong membrane of dense fibrous tissue. Covers a long bone everywhere except joint surfaces(where it’s covered by articular cartilage) 5. Yellow bone marrow- soft marrow, inactive fatty form of marrow found in adult skeleton. 6. Endosteum- thin membrane lining the medullary cavity. 7. Medullary cavity-hollow area inside the diaphysis of long bone. 8. Compact bone – contains osteons (Haversian systems) calcified matrix arranged in layers that look like rings of an onion (concentric lamella-each ring) 9. Red marrow cavities – red marrow is soft connective tissues and it produces red and white blood cells. 10. Epiphyseal line – an epiphyseal plate that has become ossified. Indicator of the boundary between diaphysis and epiphysis. 11. Cancellous (spongy) bone – contains many spaces, the cavities are filled with red or yellow marrow. The beams that form the “lattice” of spongy bone are caked Trabeculae. 12. Articular cartilage – thin layer of hyaline cartilage that covers each epiphysis. Functions like a thin smooth rubber cushion over the ends of bones where they form a joint. SPROTT SHAW COLLEGE PAGE 1 OF 4 0223/PN105/SESSION4
