Test: Epithelial Tissue - Question 10

Epithelium of bronchi is 

Detailed Solution for Test: Epithelial Tissue - Question 10

Bronchi are tube like structures that allow air to be transported from the surrounding atmosphere to the lung. The respiratory system (airways) consists of the trachea (essentially a large bronchi) that branch off into smaller and smaller bronchi before reaching the most distal lung alveoli, where oxygen can be transferred to the blood.

The respiratory bronchus is lined by respiratory epithelium comprising an admixture of pseudostratified ciliated columnar epithelium, goblet cells (mucin producing cells also termed mucous cells) and basal cells that function as progenitor cells for both the ciliated columnar cells and goblet cells.

Detailed Solution for Test: Epithelial Tissue - Question 23

The corneal epithelium is the outermost layer of the cornea. It is composed of a single layer of basal cells and 4-5 cell layers of nonkeratinized, stratified squamous epithelial cells, which are held together by tight junctions, to form an effective barrier against fluid loss and pathogen penetration.

Test: Epithelial Tissue - Question 24

Epithelial tissue originated from

Detailed Solution for Test: Epithelial Tissue - Question 24

Epithelial tissues are derived from all of the embryological germ layers:

  • from ectoderm (e.g., the epidermis)
  • from endoderm (e.g., the lining of the gastrointestinal tract)
  • from mesoderm (e.g., the inner linings of body cavities)

However, it is important to note that pathologists do not consider endothelium and mesothelium (both derived from mesoderm) to be true epithelium. This is because such tissues present very different pathology. For that reason, pathologists label cancers in endothelium and mesothelium sarcomas, whereas true epithelial cancers are called carcinomas. Additionally, the filaments that support these mesoderm-derived tissues are very distinct. Outside of the field of pathology, it is generally accepted that the epithelium arises from all three germ layers.

Test: Epithelial Tissue - Question 27

Cells of Peritoneum comprise

Detailed Solution for Test: Epithelial Tissue - Question 27
Cells of Peritoneum comprise:
- Squamous Epithelium: Squamous epithelial cells are flat and thin, resembling scales. They are the most common type of cells found in the peritoneum.
Other types of epithelial cells that can be found in the peritoneum include:
- Ciliated Epithelium: Ciliated epithelial cells have hair-like structures called cilia on their surface. These cells are found in areas such as the fallopian tubes and respiratory tract.
- Glandular Epithelium: Glandular epithelial cells are specialized for secretion and are found in glands throughout the body. They secrete substances such as mucus, enzymes, and hormones.
- Columnar Epithelium: Columnar epithelial cells are tall and slender, with a rectangular shape. They are found in areas such as the intestines, where they help with absorption and secretion.
It is important to note that the peritoneum is a membrane that lines the abdominal cavity and covers the organs within it. It consists of a layer of mesothelial cells, which are a type of epithelial cell. These cells secrete a fluid that lubricates the organs and allows them to slide against each other during movement.
In conclusion, the cells of the peritoneum comprise squamous epithelium, ciliated epithelium, glandular epithelium, and columnar epithelium, with squamous epithelium being the most common type.
Test: Epithelial Tissue - Question 28

Ciliated Epithelium occurs in frog
