Epithelia and gland tissue
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
