Book Chpts 5; pgs 114-132 6; 135-146 7; 149-170 8; 175-206 Histo Review – Outline of things to know: Stuff I added later is italicized, all other is stuff he went over in review I. CTP Basic cell of CTP Wandering cells, fixed cells Tendon vs ligament Know: histamine, heparin, serotonin Name all types of CTP, where they are located, function, and what their properties are (as far as looking under microscope) II. Cartilage Unique b/c no blood vessels, no nerves (remember, epithelial has no blood vessels…cartilage takes it to another level with no blood vessels Most common type is hyaline cartilage Growth mechanisms: Appositional – layering, grows around interstitial Interstitial – grows in four directions Basic cells of cartilage – chondrocyte (chondroblast first) Lacunae present Isogenic group – 2 or more chondrocytes occurring in one lacunae Perichondrial layer – perichondrium Perichondrial appositional III. Bone Four types of bone cells (1) Osteoprogenitor Stem Cell by duplication/replication Osteoprogenitor Can exist as osteoprogenitor or by way of differentitation we go to num 2, 3, and 4 below (2) Osteoblast

Active matrix forming cell – builds bone (3) Osteocyte Resting cell in a lacunae (4) Osteoclast Breaks down bone Osteoclasts stay in Howship’s Lacunae Bone growth Lengthwise (think cartilage on the ends of the bone) Intracartiloginous ossification Widthwise (think periostium/membrane on the outside of the bone) Intramembranous ossification 3 types of lamellae formation for compact bone: 1. Haversion system 2. Interstitial system 3. Inner circum/outer circum Canal patterns (a) parallel with long axis – haversion canal (b) connecting -- volkman’s canal Endosteum - single layer of cells; look like simple squamous; don’t confuse this with pattern of compact bone Periosteum – Membrane, not the bone itself, great healer of bone How does calcitonin and Parathyroid Hormone (PTH) affect bone? IV. Blood Vessels V. Blood 2 categories Functions of all blood cells 5 representations of leukocytes, erythrocytes, and platelets VI. Bone marrow; blood cell lineages Bone marrow and blood cell formation Know the chart of blood cells What does a cell give rise to Where does the cell come from

VII. 5 steps of tissue preparation – only the steps VIII. Regeneration – Metaplasia IX. Damaged tissue gets healed by the following (in other words, the basic cells are the healing component of the tissues): Chondrocytes (cartilage) Fibrocytes (CTP) All Blood Cells (blood) X. Re-visit joint classifications and movements XI. Stem cells make (1) themselves and (2) stem-line (differentiation) Histology – Exam 2 – my notes All Connective Tissue Connective tissues were formed in this order Mesoderm Mesencyme the 5 types of CT 5 types of connective tissue: CTP (pus-like) Loose CTP Dense irregular CTP Dense regular CTP Reticular CTP Adipose CTP Elastic CTP Mucoid CTP Cartilage (gel-like) Hyaline cartilage Elastic cartilage Fibro cartilage
