Connective Tissues Flashcards
Functions of Connective Tissue
-Establish a structural framework for the body
-Transport fluids and dissolved materials
-Protect delicate organs
-Support, surround, and interconnect other types of tissue
-Store energy, especially int he form of triglycerides
-Defend the body from invading microorganisms
Function of Fibroblast
Produces fibers in cells in the extracellular matrix
Function of Macrophage
Can reach out cell membrane and can use endocytosis to grab bacteria to eat it
Types of Proper Connective Tissue
Loose and Dense
Types of Loose Proper Connective Tissue
Areolar, Adipose, and Reticular
Types of Dense Proper Connective Tissue
Dense regular, Dense irregular, and Elastic
Types of Fluid Connective Tissues
Blood and Lymph
Types of Supporting Connective Tissues
Cartilage and Bone
Types of Cartilage Supporting Connective Tissues
Hyaline cartilage, Elastic cartilage, and Fibrocartilage
-Widely distributed; found under skin, around organs, between muscles
-Wraps and cushions organs
Areolar Connective Tissue
-Closely packed adipocytes that have nucleus pushed to the side by large fat droplet
-Provides reserve food fuel; insulates against heat loss; supports and protects organs
Adipose Connective Tissue
-Primarily parallel collagen fibers; a few elastic fibers
-Attaches to muscles to bones or to muscles; attaches bones to bones; withstands great tensile stress when pulling force is applied in one direction
Dense Regular Connective Tissue Proper
-Dense regular connective tissue containing a high proportion of elastic fibers
-Allow tissue to recoil after stretching; maintaining pulsatile flow of blood through arteries; aids passive recoil of lungs following inspiration
Elastic Connective Tissue Proper
-Amorphous but firm matrix; collagen fibers form an imperceptible network; chondroblasts produce the matrix and when mature (chondrocytes) lie in lacunae
-Supports and reinforces; served as resilient cushion; resists compressive stress
Cartilage: hyaline
-Similar to hyaline cartilage, but more elastic fibers in matrix
-Maintains the shape of a structure while allowing great flexibility
Cartilage: elastic
