Connective Tissues Flashcards
Areolar (Loose)
L- Everywhere
F- Cushions and protects
S- mainly empty space, with microphages (types of white blood cells that kills and removes dead cells and bacteria. Can be a fluid reservoir during inflammation
Adipose
L- under skin, around major organs
F- Insulates, protects, ad fuels storage
S- large number of adipocytes (cells made for storage of fats). Stored lipids take up most of the cell’s space and pushes nucleus to the side
Hyaline Cartilage
L- Ends of bones, trachea
F- Support and flexibility
S- Collagen fibers hidden by “rubbery” matrix, unorganized. Chondrocytes (produce collagen) sit in a “hole”/Lacunae
Elastic Cartilage
L- Ears and larynx
F- support and elasticity
S- large amounts of elastic fibers. Chrondrocytes still in lacunae
Bone
L- Bone
F- Supports and protects. Makes blood cells. Stores/releases inorganic chemicals
S- Osteocytes sit in a lacunae, the center point. Loos like tree rings
Blood
L- Made in red marrow of bones
F- Transports materials, and fights disease
S- Matrix is a fluid called plasma, contains RBC’s WBC’s and platelets
Dense
L- Tendons and Ligaments
F- Strength and flexibility
S- Mostly collagen fibers. Fibroblasts found between fibers/ empty space
Fibrocartilage
L- Vertebral discs
F- shock absorber
S- large abouts of collagen fibers, sometimes with cell clusters
Three Types of Fibers
Collagenous Fibers
L- Tendons/ligaments
F- Responsible for strength and flexibility
S- Rope-like structure, fairly straight
Three Types of Fibers
Reticular fibers
L- form frame work for liver, spleen, and bone marrow
F- responsible for strength, resists forces in many directions
S- rope-like, but branched, heading in multiple directions
Three Types of Fibers
Elastic Fibers
L- elastic cartilage
F- stretches and goes back to original shape, flexibility
S- branched and wavy fibers
