Study Notes
Adult Tissue Classes
- Four primary classes of adult tissues: epithelial, connective, muscle, and nervous tissues.
Embryonic Germ Layers
- Three embryonic germ layers: ectoderm, mesoderm, and endoderm.
- Ectoderm gives rise to skin and nervous tissue.
- Mesoderm leads to muscle, bone, and blood.
- Endoderm forms internal organs like the digestive tract and respiratory system.
Properties of Connective Tissues
- Generally support and bind other tissues.
- Have a diverse range of functions, including storage, transport, and protection.
- Composed of cells, fibers, and a ground substance (matrix).
Types of Cells in Connective Tissue
- Fibroblasts: synthesize fibers and ground substance.
- Adipocytes: store fat and provide insulation.
- Macrophages: involved in immune response and debris removal.
- Mast cells: release histamine for inflammatory responses.
- Leukocytes: white blood cells that defend against pathogens.
Matrix of Connective Tissue
- The matrix is a non-cellular component consisting of ground substance and fibers.
- Components of the matrix include collagen fibers (strength), elastic fibers (flexibility), and reticular fibers (support).
Types of Connective Tissue
- Loose connective tissue: softer, flexible; contains fibroblasts, collagen, and elastin.
- Dense connective tissue: strong, with closely packed collagen fibers; found in tendons and ligaments.
- Adipose tissue: stores fat; reduced extracellular matrix, large adipocytes.
- Cartilage: firm but flexible; cells called chondrocytes in a gel-like matrix.
- Bone: rigid tissue; osteocytes embedded in a mineralized matrix.
- Blood: fluid connective tissue; consists of red blood cells, white blood cells, and platelets in plasma.
- Reticular connective tissue: forms a supportive framework in organs; contains reticular fibers.
- Elastic connective tissue: allows for stretching; abundant in elastin fibers; found in arterial walls.
- Hyaline cartilage: smooth and glassy; found in joints and respiratory tract; provides flexible support.
- Fibrocartilage: tough and durable; abundant in intervertebral discs and menisci.
Recognizing Connective Tissue Types
- Visual identification includes recognizing the unique cellular arrangements and matrix characteristics for each type, including color, fiber density, and overall structure in microscopy or photographs.
