Study Notes
Epithelial Tissue
- Cuboidal epithelium is formed by cube-like cells with square sections.
Cell Junctions
- Tight junctions, desmosomes, and gap junctions are specialized structures that physically and functionally connect individual cells.
Tissue Classification
- Histological classification is based on the structure of cells according to their functions.
Epithelial Cell Appearance
- Flattened cells with irregular borders arranged to form a thin layer in epithelial tissues appear scale-like.
Epithelial Tissue Types
- Simple squamous epithelium appears polygonal when viewed from the top.
- Cuboidal epithelium is characterized by cube-like cells with hexagonal free surfaces.
Junction Types
- The three types of junctions mentioned are tight junctions, desmosomes, and gap junctions.
Adipose Tissue
- Adipose tissue is known for its high fat content.
Frog Anatomy
- In frogs, various systems are housed in the body cavity.
Ecological Importance
- The primary benefit of frogs to the ecosystem is that they serve as a food source for other animals.
Nervous System
- The nervous system in frogs is responsible for control and coordination of activities.
