Study Notes
Connective Tissue
Definition
- Connective tissue is a type of tissue that provides support, structure, and connectivity to the body
- It is characterized by the presence of a matrix, which is a non-living substance that surrounds the cells
Functions
- Provides structural support and framework for the body
- Connects and binds organs and tissues together
- Provides cushioning and shock absorption
- Acts as a medium for the exchange of nutrients and waste products
- Plays a role in the immune system by providing a barrier against infection and disease
Types of Connective Tissue
-
Loose Connective Tissue
- Found throughout the body, particularly in areas that require flexibility and elasticity
- Composed of a loose network of fibers and cells
- Functions: provides support and cushioning, allows for movement and flexibility
-
Dense Connective Tissue
- Found in areas that require strength and rigidity
- Composed of a dense network of fibers and cells
- Functions: provides strength and support, anchors muscles and bones
-
Cartilaginous Connective Tissue
- Found in areas that require flexibility and support, but not weight-bearing
- Composed of chondrocytes and a matrix of collagen and proteoglycans
- Functions: provides support and cushioning, reduces friction between bones
-
Bony Connective Tissue
- Found in bones, provides structural support and protection
- Composed of osteocytes, osteoblasts, and osteoclasts, and a matrix of collagen and hydroxyapatite
- Functions: provides structural support, protects internal organs, and facilitates movement
-
Adipose Connective Tissue
- Found throughout the body, particularly in areas that require energy storage
- Composed of adipocytes and a matrix of collagen and reticular fibers
- Functions: provides energy storage, insulation, and cushioning
-
Blood Connective Tissue
- Found in the circulatory system, responsible for transporting oxygen and nutrients
- Composed of blood cells, platelets, and plasma
- Functions: transports oxygen and nutrients, regulates body temperature, and maintains pH balance
Cells and Matrix
-
Cells
- Fibroblasts: produce collagen and other proteins
- Adipocytes: store energy in the form of fat
- Chondrocytes: produce cartilage matrix
- Osteocytes: maintain bone tissue
-
Matrix
- Composed of collagen, elastin, proteoglycans, and other proteins
- Provides structure and support to the tissue
- Allows for movement and flexibility
