Spermatogenic cells that are not commonly found in the spermatogenic epithelium include spermatogonia, primary spermatocytes, and secondary spermatocytes, as these are typically present during specific stages of spermatogenesis. However, mature spermatozoa are usually found in the lumen of the seminiferous tubules rather than the epithelium itself. Additionally, Sertoli cells, which support and nourish the developing sperm cells, are also present but are not classified as spermatogenic cells.
No, cells of the esophageal epithelium are not ciliated. The esophagus is lined with stratified squamous epithelium, which lacks cilia. Cilia are more commonly found in respiratory epithelium to help move mucus and particles.
The tough waterproof material found in the upper layers of stratified squamous epithelium is keratin. Keratin provides strength and water resistance to the epithelial cells, which are commonly found in areas that experience mechanical stress or friction, such as the skin.
The goblet cells are found and scattered among the other cells in the epithelium.
The olfactory epithelium occupies an area of about 5 cm2 in the roof of the nasal cavity. The specialized receptor cells in the olfactory epithelium are surrounded by supporting cells, non-sensory epithelial cells. The olfactory receptor cells are bipolar neurons whose olfactory cilia extend outward from the epithelium.
Stratified squamous epithelium is commonly found in areas exposed to mechanical stress, such as the skin and the lining of the oral cavity, esophagus, and vagina. This type of epithelium consists of multiple layers of cells that can withstand abrasion and friction.

Transitional epithelium cells can stretch. They can be found in organs that have the ability to stretch such as the bladder.

Mucous and Serous glands are individual secretory cells found in nonsecretory epithelium. These cells secrete mucin or proteins respectively, which help in protecting and lubricating the epithelial surface.
The nasopharynx is lined with respiratory epithelium, which consists of pseudostratified ciliated columnar epithelial cells. These cells have cilia that help trap and move mucus and particles along the respiratory tract for removal.
Transitional epithelium (also known as urothelium) is a type of tissue consisting of multiple layers of epithelial cells which can contract and expand. These cells, part of the epithelium, are found in the urinary bladder, in the ureters, and in the superior urethraand gland ducts of the prostate.
Stratified squamous epithelium consists of several layers of cells, which protect the areas of the body It can be found in areas such as the esophagus, mouth, and the outer portion of the skin (epidermis).
Ciliated epithelium cells in amphibians are typically found in areas of the respiratory tract and parts of the reproductive system. They help in moving mucus and particles, aiding in breathing and reproduction.
