Syndesmosis – interosseous membrane connect bones 1 ° Cartilaginous = Growth plate – synchondrosis/ synostosis 2 ° Cartilaginous = Hyaline cartilage = Symphysis Metaphysis = site of osteogenesis Synostosis = physis ossifies = epiphyseal LINE Physis = growth plate blood supply = epiphyseal vessels Epi/Metaphysis blood supply = metaphyseal vessels PseudoFx on Xray Growth plate doesn’t ossify so leaves a region of cartilage Harris lines = malnutrition for 10 days or more = growth-arest lines Avulsion fx = ligament pulls on bones in kids Salter-harris fractures = fractures through growth plate Diarthosis = synovial joint Fibrous capsule = merge w/ periosteum Synovial membrane = secretes fluid = hyaluronic acid = monocyte rich Venae comitantes = medium-sized arteries – bound in same non-compliant sheath = bad ones are traumatic and iatrogenic arteriovenous fistulas Anatomical end arteries = central artery of retina and renal interlobular arteries Arteriole-muscular venule connections = preferential thoroughfare channels = not
