Study Notes
Human Organization - Types of Tissues
- Tissues are composed of similar cells
- Four major types: epithelial, connective, muscular, and nervous
Epithelial Tissue
- Tightly packed cells forming a continuous layer
- Covers surfaces and lines body cavities
- Functions: protection, secretion, absorption, excretion, and filtration
- Junctions between cells: tight, gap, and adhesion junctions
Connective Tissue
- Binds organs together
- Provides support and protection
- Fills spaces
- Produces blood cells
- Stores fat
Loose Fibrous & Dense Fibrous Tissues
- Loose fibrous: supports epithelium and internal organs
- Contains collagen fibers
- Fibroblasts are the cells
- Dense fibrous: tendons and ligaments
- Densely packed collagen fibers
Adipose Tissue & Reticular Connective Tissue
- Adipose: fibroblasts enlarge to store fat
- Reticular: forms supporting meshwork of lymphoid tissue
Cartilage & Bone
- Cartilage: A flexible form of connective tissue
- Three types: hyaline, elastic, and fibrocartilage
- Allows bones to slide at joints
- Bone: The most rigid connective tissue
- Composed of a hard matrix
- Compact bone forms the shaft of long bones
- Spongy bone forms the ends of long bones
Blood
- Not made of cells, but a liquid layer containing plasma
- Plasma makes up about 55% of blood volume
- Red blood cells: carry oxygen to tissues
- White blood cells: fight infection
- Platelets: involved in clotting
Muscular Tissue
- Made of muscle fibers (actin & myosin)
- Three types: skeletal, smooth, and cardiac
Nervous Tissue
- Contains nerve cells called neurons
- Functions: sensory input, integration, and motor output
- Supports and nourishes neurons using neuroglia
