Study Notes
Macrophage Cytoplasm
- Contains numerous lysosomes and phagosomes, reflecting the cell's phagocytic activity
Loose Connective Tissue
- Characterized by a loosely arranged network of fibers and cells embedded in a gel-like ground substance
Tendons and Ligaments
- Composed of dense regular connective tissue, a type of connective tissue with tightly packed collagen fibers, aligned in parallel bundles
Macrophage Origin
- Macrophages originate from monocytes, a type of white blood cell, which differentiate into macrophages in tissues
Macrophage Nucleus
- Macrophage nuclei are typically large, indented, and often kidney-shaped, reflecting the cell's active state
### Macrophage Function
- Macrophages play a crucial role in the immune system by engulfing and destroying pathogens, cellular debris, and foreign particles
### Dermis Connective Tissue
- The dermis of the skin is primarily composed of dense irregular connective tissue, characterized by a dense network of collagen fibers arranged in an interwoven pattern
Dense Connective Tissue
- Dense connective tissue features a high density of collagen fibers, providing significant strength and support
### Large Artery Connective Tissue
- The walls of large arteries are rich in elastic connective tissue, allowing for the expansion and recoil necessary for blood pressure regulation
### Connective Tissue Classification
- Connective tissues are primarily classified based on the types and arrangement of their extracellular matrix components, specifically the fibers, ground substance, and cells present.
