Skeletal System, Joints and Osteogenesis
CT 3280 White fibro-cartilage; Pubic symphysis: sec  endochondral bone formation on each side of pubic symphysis 
CT 3283 Membranous bone fatal skull: sec blue matrix around teeth and between desnse ct of dermal bones;inner periosteum (enosteum), mesenchyme
CT 3287 Developing long bone: l.s. hyaline cartilage model; osteogenic cells, periosteum, diaphysis, bone collar; enchondral ossification (zones of): reserve cartilage cells; proliferation, hypertrophy, calcifying cartilage, erosion and ossification (replacement); bony (osteoid) matrix; marrow cavity, spicules of cancellous bone, osteoblasts, osteocytes, lacunae; osteoclasts, resorption lacunae (Howship's); epiphysis, articular cartilage; secondary ossification center
CT 3291 Compact bone decalcified: c.s. look for osteoclasts and absorption (Howship's) lacunae; peripheral compact bone
CT 3319 Joint; fetal pig foot; sec hyaline cartilage model; osteogenic cells, periosteum, diaphysis, bone collar; enchondral ossification (zones of): reserve cartilage cells; proliferation, hypertrophy, calcifying cartilage, erosion and ossification (replacement); bony (osteoid) matrix; marrow cavity, spicules of cancellous bone, osteoblasts, osteocytes, lacunae; osteoclasts, resorption lacunae (Howship's); epiphysis, articular cartilage; secondary ossification center; synovial cavity, folds and projections
CT 3539 Muscle-tendon connection: sec junction of collgen fibers (note corrugation) and skeletal muscle
CT 6140 Bone dry ground human: c.s. compact bone: lacunae, cannaliculi, interstitial lamellae, osteons
CT 6143 Bone dry ground human: l.s. compact bone: lacunae, cannaliculi, interstitial lamellae, osteons



Hematopoiesis
Circ/Hemato
6564 
not 4095
red bone marrow: human smear dentify mitotic and post-mitotic cells: 
erythroid line: proerythroblast, basophilic erythroblast, polychromatophilic erythroblast, orthochromatophilic erythroblast (acidophilic erythroblast or normoblast); 
myeloid line: myeloblast, promyelocyte, early --myelocyte (some granules in cytoplasm) late --myelocyte (nucleus reniform, specific granules discernible -- eosinophilic granules most conspicuous), -- metamyelocyte (nucleus more nearly bilobed), band (stab) cells;
monocyte line and lymphoblast line difficult to distinguish from myeloid line. 
megakaryoblasts and megakaryocytes
