type of cartilage? which skull is younger? 9184a64f-4439-447c-85dc-cfcdd222e872.jpeg (image/jpeg) hyaline cartilage right side skull younger because it's wider... it hasn't calcified yet
what tissue? young or old person? 8e6b2fa4-8133-43fe-ae66-1b95f1bc1673.jpeg (image/jpeg) hyaline cartilage young MRI
which one is older? 7f2049e9-6975-4bc2-887a-92c91e89a970.jpeg (image/jpeg) older b/c calcified she said one on left it older

DEFINE GIANTISM excess of GH in children, Gplates keep growing, excessive growth of LONG BONES
what is Intramembranous ossification by direct mineralization of matrix secreted by osteoblasts
Acromegaly is excess of GH in adults, Gplates already closed, long bones become thicker, bigger hands, bigger feet, changingshoe size in a few month
Dwarfism--- lack of GH in children to stimulate the overall growth, especially thatof epiphyseal plates
Osteoporosis-- decrease in bone mass caused by decreased bone formation, increased bone resorption, or both, found in immobilized patients and in postmenopausal women
Osteomalacia is (soft)– Ca deficiency in adults, recently formed bone not calcified enough, or partial decalcification of already calcified matrix
Rickets Rickets– Ca deficiency in children, notcalcified normally, distorted growth plate,bones grow slowly and deformed
scurvy is a lack of Lack vitamin C, essential for collagensynthesis, scurvy, weak bones/ligaments
calcium malnutrition results in Ca malnutrition results in bonedecalcification, easy to fracture, less densein X-rays
vitamin D is important for _____ absorption in intestines Lack vitamin D, important for Ca absorption in intestines
hyperparathyroidism causes Excess PTH in hyperparathyroidism can cause bone decalcification, resorption, toomuch in blood, abnormal Ca deposit inarterial walls, in kidneys as calculi/stones
calcitonin does what Calcitonin inhibits osteoclast activity orresorption, less Ca in blood, more to bone
osteoclast function defect causes? Osteoclast function defect, bone overgrowth, thickening, hardening
Respond to stress from orthodontic appliances, bone deposition happens where? Respond to stress from orthodontic appliances, bone deposition on the side where the traction is applied,
orthodontic bone resorption happens where? bone resorption where the pressure is exerted(opposite side),
in ortho the tooth moves toward the _______ side tooth is moved toward the resorbed side (osteoclasts side)
TURNOVER RATE FOR YOUNG AND OLD PEOPLE •The turnover rate is very active in young children– In young, more built up than broken down– In between, built up equals broken down–Older than 40, less built up than brokendown
Intracartilaginous/endochondralossification --- by depositon of bone matrix onpre-existing cartilage model
Step/Zones in endochondral osteogenesis 1. Resting zone 2. Zone of proliferation, columns/stacked 3. Zone of hypertrophy, enlarged cells, produceECM, cartilage grows interstitially 4. Zone of calcification of cartilage matrix, cells die 5. Zone of ossification, osteoprogenitor cells move in, dif into osteoblasts, lay down matrix appositionally on calcified cartilage matrix, trapped in own matrix, then become osteocytes 6. Resorption of new bone and calcified cartilage
Articular cartilage Articular cartilage– persists thru out adult life, does NOT contribute to bone growth in length
Epiphyseal plate or growth plate–responsible for Epiphyseal plate or growth plate–responsible for bone growth in length,disappears in adults, stop growing in height,remnants= epiphyseal lines
