1. Leydig's cells2. Oxyntic cells3. Interstitial cells4. Sertoli cells

Answer»

1. The basic function of the leydig's cells is to produce male sex hormone called testosterone in response to the LH secreted. It maintains male's secondary sexual characters.

2. Parietal cells (also known as oxyntic or delomorphous cells), are the epithelial cells that secrete hydrochloric acid (HCl) and intrinsic factor. These cells are located in the gastric glands found in the lining of the fundus and in the body of the stomach.

3. Leydig cells, also known as interstitial cells of Leydig, are found adjacent to the seminiferous tubules in the testicle. They produce testosterone in the presence of luteinizing hormone (LH).

4. The function of Sertoli cells is to 'nurse' developing sperm through this process. Located in the walls of the seminiferous tubules, they are one of the few cells that stay inside the tubules permanently.
