Leydig cells
D
Sertoli cells
Verified step by step guidance
1
Understand the role of inhibin: Inhibin is a hormone that plays a key role in regulating the production of follicle-stimulating hormone (FSH) by the anterior pituitary gland. It is involved in the negative feedback mechanism to control spermatogenesis in males and follicular development in females.
Identify the location of Sertoli cells: Sertoli cells are specialized cells located within the seminiferous tubules of the testes. They provide structural and nutritional support to developing sperm cells and are involved in the regulation of spermatogenesis.
Learn the function of Sertoli cells in inhibin secretion: Sertoli cells secrete inhibin in response to FSH stimulation. Inhibin then acts on the anterior pituitary to suppress further secretion of FSH, maintaining hormonal balance in the male reproductive system.
Differentiate Sertoli cells from other cell types: Alpha cells and Beta cells are found in the pancreas and are responsible for secreting glucagon and insulin, respectively. Leydig cells, located in the testes, produce testosterone but do not secrete inhibin.
Conclude that Sertoli cells are the correct answer: Based on their location and function, Sertoli cells are the cells responsible for secreting inhibin in the human body.
