Lab Chp. Three: Connective, Muscular, and Nervous Tissue Flashcards
General Traits of Connective Tissue
- Most abundant tissue type
- vary in levels of vasularization
- contains cells dispersed in extracellular matrix (matrix is made up of protein fibers and ground substances)
Functions of connective tissues:
- provide support and protection
- help repair from tissue damage
- help protect against infection
- serve as frameworks or bind structures
- May fill: spaces, store fat, or make blood cells
Fibroblast
Produces Fibers
*Connective Tissue
Macrophages
Aid the immune system by doing phagocytosis
*Connective tissue
Mast Cells
Release herapin and/or histamine
*Connective tissue
very strong
Collagen Fibers
*Connective tissue
Elastic Fibers
Allows for expansion and contraction of a tissue
*Connective tissue
Reticular Fibers
very thin, highly branched, collagenous fibers
*Connective tissue
Thinnest of the three fiber types
Reticular fibers
Connective tissue proper
- loose connective tissue
- adipose tissue
- regular connective tissue
- dense connective tissue
- elastic connective tissue
specialized connective tissue
- cartilage
- bone
- blood
- Mainly fibroblasts with collagen and elastic fibers
- Fluid to gell-like matrix
- binds skin to most structure
- Found between muscles
Loose connective tissue
-many collagen fibers and elastic fibers with few fibroblasts
Dense Connective Tissue
- Many elastic fibers and some collagen fibers and fibroblasts
- Form walls of large airways, arteries, and the heart
Elastic Connective Tissue
- Composed of reticular fibers
- Support structure for organs
Reticular connective tissue
_____ carry blood at a higher blood pressure than veins
arteries
- Made up of adipocytes
- Cushions, insulates, and stores fat
Adipose
- Osteocytes and a solid matrix
- Forms the skeleton
Osseous tissue (bone)
General traits of cartilage:
- chondrocytes in lacunae and a rigid matrix
- has a poor blood supply
- exists in three types
3 types of cartilage:
- Hyaline Cartilage
- Fibrocartilage
- Blood
Most abundant type of cartilage:
Hyaline Cartilage
Found at the end of bones
