Lab 4 Flashcards
(21 cards)
Fibers in connective tissue
collagen (strength), elastic and reticular (support)
What are the three broad groups of Connective tissue
Connective tissue proper, fluid, supporting
Connective tissue matrix is
thick liquid, variety of cell types
Fluid connective tissue matrix is
liquid tissues that flow through vessels
Supporting connective tissue matrix
strong gelatinous or solid matrix
2 Groups of Connective Tissue Proper
Loose and Dense
Areolar tissue
random arrangement of cells and fibers - looks like a party with streamers
Adipose tissue
made up almost entirely of adipose (fat ) cells with a large vacuole for fat, looks like chicken wire
Reticular Tissue
looks like grape vines or a tree with blossoms
Dense Regular
Fibroblasts are in rows sandwiched between collagen fibers, collagen fivers are layered in an organized arrangement appear wavy
Dense Irregular
Fibroblasts are more scattered throughout the tissue. collagen fibers are randomly arranged
Elastic Tissue
Dense regular connective tissue with elastic fibers in the matrix, thicker than collagen fibers
Fluid Connective tissue
includes blood and lymph tissue, liquid matrix an circulate in blood or lymphatic vessels, circular blobs with space in between
Types of Supporting Connective Tissue
Cartilage, Bone
Cartilage description
rubbery, avascular with a gelatinous matrix
bone
solid matrix of calcium phosphate and calcium carbonate
What separates cartilage from neighboring tissues
Perichondrium
Hyaline Cartilage
only cartilage type with no visible fibers
Elastic Cartilage
chondrocytes appear larger than other cartilages; elastic fibers look like plant roots branching in the soil
Fibrocartilage
has the most collagen fibers of the cartilages, and they often appear in a wavy pattern ; chondrocytes are often seen in rows or small clusters
Bone
in cross section, looks like tree stumps
