<P> The anterior lobe of the pituitary can be divided into the pars tuberalis (pars glandularis) and pars distalis (pars glandularis) that constitutes ~ 80% of the gland . The pars intermedia (the intermediate lobe) lies between the pars distalis and the pars tuberalis, and is rudimentary in the human, although in other species it is more developed . It develops from a depression in the dorsal wall of the pharynx (stomal part) known as Rathke's pouch . </P> <P> The anterior pituitary contains several different types of cells that synthesize and secrete hormones . Usually there is one type of cell for each major hormone formed in anterior pituitary . With special stains attached to high - affinity antibodies that bind with distinctive hormone, at least 5 types of cells can be differentiated . </P> <Table> <Tr> <Th> S.No . </Th> <Th> Type of cell </Th> <Th> Hormone secreted </Th> <Th> Percentage of type of cell </Th> </Tr> <Tr> <Td> 1 . </Td> <Td> Somatotropes </Td> <Td> human growth hormone (hGH) </Td> <Td> 30 - 40% </Td> </Tr> <Tr> <Td> 2 . </Td> <Td> Corticotropes </Td> <Td> adrenocorticotropin (ACTH) </Td> <Td> 20% </Td> </Tr> <Tr> <Td> 3 . </Td> <Td> Thyrotropes </Td> <Td> thyroid stimulating hormone (TSH) </Td> <Td> 3--5% </Td> </Tr> <Tr> <Td> 4 . </Td> <Td> Gonadotropes </Td> <Td> gonadotropic hormone i.e., both luteinizing hormone (LH) and follicle stimulating hormone (FSH) </Td> <Td> 3--5% </Td> </Tr> <Tr> <Td> 5 . </Td> <Td> Lactotropes </Td> <Td> prolactin (PRL) </Td> <Td> 3--5% </Td> </Tr> </Table> <Tr> <Th> S.No . </Th> <Th> Type of cell </Th> <Th> Hormone secreted </Th> <Th> Percentage of type of cell </Th> </Tr>
