Study Notes
Types of Animal Tissues
- Tissues are groups of cells with similar structure and function.
- Four main types of animal tissues: Epithelial, Connective, Muscular, and Nervous.
Epithelial Tissue
- Comprises the inner and outer linings of organs, surfaces, and the main glandular tissue.
- Simple Squamous Epithelium:
- One layer of flat, scale-like cells.
- Example: Alveoli (air sacs in the lungs) and capillary walls.
- Function: Diffusion and exchange of substances.
- Simple Cuboidal Epithelium:
- One layer of cube-shaped cells.
- Example: Glands and their ducts, ovaries, and kidney tubules.
- Function: Secretion and absorption.
- Simple Columnar Epithelium:
- One layer of elongated (column-like) cells.
- Example: Lining of the gastrointestinal tract.
- Function: Absorption and secretion, contains goblet cells that secrete mucus.
- Pseudostratified Columnar Epithelium:
- Appears stratified but is a single layer, often with cilia.
- Function: Secretion and movement of mucus.
- Stratified Squamous Epithelium:
- Multiple layers of flat cells.
- Provides protection against abrasion.
- Stratified Cuboidal Epithelium:
- Multiple layers of cube-shaped cells.
- Function: Protection and secretion.
- Stratified Columnar Epithelium:
- Multiple layers with columnar cells on top.
- Functions in protection and secretion, found in areas like ducts.
Connective Tissue
- Provides support, binds other tissues together, and plays a role in transport and storage.
- Various types: loose connective tissue, dense connective tissue, adipose, blood, bone, and cartilage.
Muscular Tissue
- Responsible for movement and includes three types: skeletal, cardiac, and smooth muscle.
Nervous Tissue
- Composed of neurons and glial cells; responsible for transmitting nerve impulses and supporting neuron function.
