Which 4 classes of basic types of tissues are there?
1. Epithelial Tissue
2. Connective Tissue
3. Muscle Tissue
4. Nervous Tissue -
In a few words, how can you describe epithelial tissue?
Epithelial tissue is tissue that covers things in the body. -
Where in the body can epithelial tissue be found?
- The outer layer of the skin;
- Body cavities and respiratory and digestive systems;
- Layers in blood vessels;
- Layers of some organs. -
Which two kinds of epithelium could you identify, seen the place in the body?
- Covering and lining epithelium (everything that enters the body has to pass epithelium);
- Glandular epithelium (the glands of the body). -
Which two surfaces does an epithelial cell have?
- The apical surface (the surface exposed to the exterior);
- The basal surface (attached to connective tissue and the rest of the organism). -
How can the apical surface of an epithelial cell be lined?
- It can be smooth;
- or it can be lined with microvilli. -
What stage do all types of tissue share in common together?
They all have the same embryonic origin -
What is the function of microvilli on the apical surface of an epithelial cell?
It increases the surface, which is handy for absorption and secretion. -
What is the endoderm germ layer and where do you find this tissue?
It is digestive tissue and is found in the lung -
What is the mesoderm germ layer and where do you find this tissue?
It is connective tissue and found in muscles
