Study Notes
Overview of Connective Tissue
- Originates from mesenchyme, the middle layer of embryonic germ layers.
- Functions include supporting and connecting body tissues, protecting and repairing, providing strength, and ensuring cohesion and internal support for organs.
- Comprises various types of tissues that differ in density and cellularity.
Functions and Characteristics
- Maintains the structural form of the body.
- Transports substances, including water, ions, and inorganic materials.
- Provides insulation and serves as storage for fat and water.
Composition of Connective Tissue
- Composed of 90% water, with specialized cells such as fibroblasts, adipocytes, macrophages, mast cells, plasma cells, and eosinophils.
- Consists of a matrix featuring glycoproteins, fibrous proteins, and glycosaminoglycans.
Extracellular Matrix
- Key feature for tissues providing mechanical function (e.g., ligaments, tendons, bone).
- Determines tissue function, with the presence of collagen being crucial for resistance to stretching and providing strength.
Collagen Fibers
- Most common type of fiber in connective tissue.
- Offers resilience and strength, especially in ligaments and tendons.
- Resistant to load and stress, thus facilitating durability.
Types of Fibers
- Reticular fibers: Form a mesh-like network, supporting structures such as the liver, lymphatic tissue, and bone marrow.
Specialized Connective Tissues
- Adipose tissue: Contains white adipose, which is semi-solid and stores energy, found around blood vessels and beneath the epidermis.
- Cartilage: Has chondrocytes embedded in a matrix of collagen and elastic fibers; includes:
- Hyaline cartilage: Provides support and flexibility.
- Fibrocartilage: Located in joints, such as the temporomandibular joint (TMJ).
- Elastic cartilage: Contains numerous elastic fibers, supporting structures like the pinna of the ear and the epiglottis.
Cell Types in Connective Tissue
- Fibroblasts: Produce fibers and extracellular matrix.
- Adipocytes: Store fat.
- Macrophages: Involved in immune response and cleaning up debris.
- Mast cells: Release histamine, playing a role in inflammation.
Learning Outcomes
- Ability to state the function and characteristics of connective tissues, describe their non-cellular substrates, list their cells and fibers, and classify various types of connective tissue.
