BIOL123 Lecture Notes - Lecture 15: Epiphyseal Plate, Hyaline Cartilage, Medullary Cavity
Document Summary
Funtion of the skeletal system: support, protection, mineral homeostasis, blood cell production, triglyceride storage. D i a p h y s i s: tubular bone shaft, consisting of bone collar surrounding a hollow medullary cavity filled with yellow bone marrow in adults. E p i p h y s es ( en d o f t h e b o n es : distal and proximal ends, consist of internal spongy bone covered by an outer layer of compact bone. M e t a p h y s e s: region in bone where diaphysis meets epiphyses. Includes epiphyseal line: replaces epiphyseal plate in growing bone, located between the epiphyses and diaphysis and is a residue of the epiphyseal plate. A r t i c u l a r c a r t i l a g e: hyaline cartilage covering the articular surfaces of the epiphyses. Internal surface of the bone is lines by a connective tissue membrane endosteum.
