Connective Tissue

Question 1

Collagen fibers

Answer 1

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

Question 2

Characteristics of connective tissue

Answer 2

*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

Question 3

Job of connective tissue

Answer 3

Good things together & provide structure and support

Question 4

Reticular fibers

Answer 4

The tiny versions of collagen fibers

Question 5

Elastic fibers

Answer 5

Can do what collagen can’t…which is return to their original position once they have been pulled or stretches. A.K.A.= yellow

Question 6

Adipose Tissue

Answer 6

-Loose connective tissue designed to store fat -Found beneath skin, around joints, padding the kidneys & other internal organs

Question 7

Bone Tissue (what letter?)

Answer 7

Bone cells, called osteocytes, lie within lacunae and are arranged in concentric circles

Question 8

Cartilage (what letter?)

Answer 8

-Rigid connective tissue providing supportive framework= -Lacks a vascular system, so it heals slowly

Question 9

Fibroblast (what letter?)

Answer 9

(A) Cells that create the tissue

Question 10

Collagen Fibers (what letter?)

Answer 10

(B) Thick white fibers that are very strong & are made by the fibroblasts through protein synthesis.

Question 11

Capillary (what letter?)

Answer 11

(C) The more room in the matrix = more blood vessels found

Question 12

Most Cell (what letter?)

Answer 12

(D) Type of WBC commonly found in CT releases histamine or heparin (anticoagulant).

Question 13

WBC (what letter?)

Answer 13

(E) Neutrophil or monocyte

Question 14

Reticular Fibers (what letter?)

Answer 14

(F) Small collagen fibers secretes by fibroblasts

Question 15

Matrix or IF (what letter?)

Answer 15

(G) Fluid filled square between cells

Question 16

Cartilage Connective Tissue Characteristics

Answer 16

-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

Question 17

Hyaline Cartilage

Answer 17

-toughest cartilage there is -wear & tears end of joints, nose, trachea, connecting ribs to sternum -white= loaded with collagen fibers

Question 18

Adipose Tissue (CT Proper)

Answer 18

-very vascular -rule breaker-has cellularity

Question 19

Loose Reticular (CT Proper)

Answer 19

-Makes up framework of non hollow organs (spleen, liver, lymph nodes) -very vascular to filter the lymph

Question 20

Dense Irregular (CT Proper)

Answer 20

-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

Question 21

Dense Regular (CT Proper)

Answer 21

-again not many blood vessels=slow healer -all fibers in one direction=strength in one direction -tendons, ligaments, fibrous membranes

Question 22

Dense Elastic (CT Proper)

Answer 22

-Mainly found under transitional epithelium, wall of respiratory pathways, wall of blood vessels -can form elastic ligaments that allows movement of vertebrae

Question 23

Answer 23

Dense Irregular (CT Proper)
