| Question | Answer |
|---|---|
| Types of CTP is determined by | 1. Ratio of cells to fibers 2. Density of Interstitial Matrix |
| AKA for loose CTP | Areolar |
| CTP where fibers are present & visible | Elastic |
| CTP type Only viewed with silver nitrate stain | Reticular |
| CTP type that is most numerous + visible in all directions | Collagen |
| Three types of fixed cells + function | 1. Fibrocytes: produce pus-like matrix 2. Adipose: bound by reticular fibers 3. Histiocytes (Macrophages): Phagocytosis |
| Two Types of loose CTP cells | 1. Fixed 2. Wandering |
| AKA for Wandering Cells | Mast Cells |
| 3 Types of wandering cells | 1. Histamine: vaso-dilation 2. Heparin: Anti coagulant 3. Serotonin: Vaso-constriction |
| Function of Wandering cells | short term effects, tissue damage or infection |
| Where do wandering cells exist | 1. WBC 2. Plasma |
| 3 locations where for wandering & fixed cells (LCTP) | 1. Mesentaries 2. Omenta 3. Hypodermis |
| How does Dense CTP compare to Loose CTP? | Dense = higher concentration of fibers |
| Dense Regular Function + location | Tensile Strength 1. Tendons & Ligaments |
| Dense Irregular is found in: | Dermis |
| Dense Irregular looks like | Spaghetti with raisins |
| Dense Regular looks like | thin purple streaks |
| 4 Types of CTP with special properties | 1. Yellow Elastic CTP 2. Adipose CTP 3. Mucoid CTP 4. Reticular CTP |
| Greatest in number (CTP with special properties) | Yellow Elastic |
| Branching Pattern (CTP with special properties) | Reticular |
| No Fibrocytes visible (CTP with special properties) | Reticular |
| Function in energy stroage + production (CTP with special properties) | Adipose |
| Wharten's Jelly (CTP with special properties) | Mucoid |
| Dark fibers stained with silver nitrate, argyrophilic (CTP with special properties) | Reticular |
| Cells look stretched out, unorganized chicken wire (raspberry jam smears) (CTP with special properties) | Mucoid |
| Regularly arranged cells with boundaries of reticular fibers (CTP with special properties) | Adipose |
| Found in ligamentum nuchae & flava (CTP with special properties) | Yellow Elastin |
| Found in humor of the eye (CTP with special properties) | Mucoid |
| Found in large Arteries (CTP with special properties) | Yellow Elastin |
| Found in lymphatic system (CTP with special properties) | Reticular |
| Found in branchi & trachea (CTP with special properties) | Yellow Elastin |
| Red & white pulp cells, function in immunity (CTP with special properties) | Reticular |
| Found in clitoris & penis (CTP with special properties) | Yellow Elastin |
| Looks like chicken wire (CTP with special properties) | Adipose |
| Pink Collagen fibers in background (CTP with special properties) | Yellow Elastin |
| Found surrounding arteries and some veins (CTP with special properties) | Yellow Elastin |
| Found everywhere except brain (CTP with special properties) | Adipose |
| Sites for B & T lymphocytes (CTP with special properties) | Reticular |
| Loses coloration at death (CTP with special properties) | Yellow Elastin |
| What kind of matrix exists in cartilage? | gel-like |
| Two ways cartilage is different than other CT | 1. No nerves or BV 2. Gets nutrients via matrix |
| Three types of cartilage | 1. Hyaline 2. Elastic 3. Fibrocartilage |
| Isogenic is: | -Two or more chondroctyes in a group -one temporary cartilage |
| Function is support & Flexibility (Cartilage Types) | Elastin |
| Can't see collagen b/c not much & it's embedded in gel (Cartilage Types) | Hylaine |
| Does not contain growth zones (Cartilage Types) | Fibrocartilage |
| No Perichondrium (Cartilage Types) | Fibrocartilage |
| Collagen fibers almost cover chondrocytes (Cartilage Types) | Fibrocartilage |
| Trnsitional tissue b/t cartilage & CTP chondrocytes found in lacunae (Cartilage Types) | Fibrocartilage |
| Only grows intersitially (Cartilage Types) | fibrocartilage |
| Found in ear, epiglottis, eustachian tube, eu-nose (Cartilage Types) | Elastin |
| Function is support only (Cartilage Types) | Hyaline |
| Function is tough support + tensile strength (Cartilage Types) | Fibrocartilage |
| Found in ventral ribs, tracheal rings, larynx, joint surfaces (Cartilage Types) | Hyaline |
| Found in IVD, Pubic symphysis, tendon to bone attachment (Cartilage Types) | Fibrocartilage |
| Christmas tree slide (Cartilage Types) | Elastin |
| most common type of cartilage | hyaline |
| Two types of cartilage growth | 1. Appositional: layer, grows around interstitial 2. Interstital: grows in 4 directions |
| Perichondrium layer of cartilage is what type of growth? | Appositional |
| What type of cells is 1st line of defense? | Wandering cells |
| Type of CT offers: Mechanical Support | Elastic or reticular |
| Type of CT offers: Exchange of metabolites | blood, wandering cells |
| Type of CT offers: storage & energy reserves | adipose |
| Type of CT offers:protection against infections | marcophages |
| Type of CT offers: Repair after injury | Fibroblasts |
| How does bone differ from other CT? | Outside layer = calcified |
| Type of bone cell: stays in lacuna | Osteoclast |
| Type of bone cell:stem cell | osteoprogenitor |
| Type of bone cell:Absorption & Re-absorption | Osteoclast |
| Growth area of bone | metaphysic |
| 3 types of lamellae formation for compact bone | 1. Haversian System (osteon) 2. Interstitial system 3. inner & outer circumferential |
| Fixed cells are responsible for? | synthesis of fiber & ground substance |
| Difference in shape of fibroblast at rest and active | 1. Rest = small nucleus 2. Active = Entire cell enlarge |
| Primitive cell | Mesenchymal |
| Where do blood cells come from | Red bone marrow |
| Which WBC is the 1st line of defense? | Neutrophil |
| How many lobes of Eosinophils? | 2 |
| How many lobes of Neutrophils? | 3-5 |
| Function of Eosinophils | Antibody-antigen complex -Allergic Rxns & Parasitic |
| Function of Neutrophils | Phagocytic Bacteria & Particular matter |
| Thrombocytes | Platelets in reptiles |
| Blood clotting steps | Platelet & Tissue cells --> Thromboplastin --> Prothrombin --> Thrombin --> fibrinogen --> fibrin |

| Monocytes function: | 1. Phagocytosis 2. Intracellular digestion *Antigen Fingerprints for future ID |
| B-lymphocytes can go to three sites | 1. Blood Stream 2. Return to BM 3. Peripheral lymph organs |
| Principle hemopoetic tissue in adult mammals | Red Bone marrow |
| 5 Places of hemopoetic tissue | 1. liver 2. spleen 3. BV 4. lymph nodes 5. thymus |
| 3 phases of embryonic hemopoeisis + time periods | 1. Yolk Sac: two weeks 2. Liver (6th week) & Spleen (2-8 month) 3. Bone marrow (3rd month) |
| Unitarian Theory | All blood cells arise from common stem cell (Hemocytoblast) |
| What proves Unitartian theory | CFU-GM |
| Stem cells have capacity to do what two things | 1. Duplication 2. Differentiation |
