Connective Tissue Flashcards
Collagen fibers
Strongest proteins the body makes, it’s formed by the cell. Vitamin C and the mineral copper are needed to form strong collagen fibers a.k.a =white fibers
Characteristics of connective tissue
*most common tissue *more matrix than cells *fibers running though the matrix *vascularity varies with different connective tissues *cella are names by tissue they make
Job of connective tissue
Good things together & provide structure and support
Reticular fibers
The tiny versions of collagen fibers
Elastic fibers
Can do what collagen can’t…which is return to their original position once they have been pulled or stretches. A.K.A.= yellow
Adipose Tissue
-Loose connective tissue designed to store fat -Found beneath skin, around joints, padding the kidneys & other internal organs
Bone Tissue (what letter?)
Bone cells, called osteocytes, lie within lacunae and are arranged in concentric circles
Cartilage (what letter?)
-Rigid connective tissue providing supportive framework= -Lacks a vascular system, so it heals slowly
Fibroblast (what letter?)
(A) Cells that create the tissue
Collagen Fibers (what letter?)
(B) Thick white fibers that are very strong & are made by the fibroblasts through protein synthesis.
Capillary (what letter?)
(C) The more room in the matrix = more blood vessels found
Most Cell (what letter?)
(D) Type of WBC commonly found in CT releases histamine or heparin (anticoagulant).
WBC (what letter?)
(E) Neutrophil or monocyte
Reticular Fibers (what letter?)
(F) Small collagen fibers secretes by fibroblasts
Matrix or IF (what letter?)
(G) Fluid filled square between cells
Cartilage Connective Tissue Characteristics
-Matrix is firm because of proteoglycans -AVascular- actually discourages by formation -Cells(chondroacytes) must live in pools because of the firm matrix. Pools are called Lacunae. -No room for nerves -Perichondrium surrounds the cartilage
Hyaline Cartilage
-toughest cartilage there is -wear & tears end of joints, nose, trachea, connecting ribs to sternum -white= loaded with collagen fibers
Adipose Tissue (CT Proper)
-very vascular -rule breaker-has cellularity
Loose Reticular (CT Proper)
-Makes up framework of non hollow organs (spleen, liver, lymph nodes) -very vascular to filter the lymph
Dense Irregular (CT Proper)
-Packed with fibers & not much room for blood vessels; slow healing -Strength in ALL directions -Periosteum (around bone), perichondrium (around cartilage), perimysium epimysium (around m+), blood vessels, & GI tract
Dense Regular (CT Proper)
-again not many blood vessels=slow healer -all fibers in one direction=strength in one direction -tendons, ligaments, fibrous membranes
Dense Elastic (CT Proper)
-Mainly found under transitional epithelium, wall of respiratory pathways, wall of blood vessels -can form elastic ligaments that allows movement of vertebrae
Dense Irregular (CT Proper)
