Hint: The anterior pituitary gland receives signal molecules from the hypothalamus and synthesizes and secretes seven hormones accordingly. The posterior pituitary gland does not produce any hormones. Instead, it stores and secretes two hormones produced in the hypothalamus.
Complete answer:
Anterior pituitary gland: adenohypophysis, is a typical endocrine gland composed of cells secreted by epithelial cells and supported by connective tissue rich in blood and lymphatic capillaries. The anterior pituitary gland originates from the ectoderm, more precisely, from the Rather sac, which is part of the induration during fetal development. Rothko’s pouch eventually lost its connection with the pharynx and formed the anterior pituitary gland.
The pouch is dedicated to organ development and then expresses a single cell type marker in the mature anterior pituitary gland. Between organ stereotyping and maturation, a series of cell type-specific differentiation and proliferation events occurred.
Hormones: The anterior pituitary gland regulates several physiological processes, including stress, growth, reproduction, and lactation. The hormones secreted by the anterior pituitary gland are corticotropin, thyroid-stimulating hormone, follicle-stimulating hormone, luteinizing hormone, growth hormone and prolactin.
Thus the correct answer is option ‘D’.
Note: Pituitary gland, the main gland controls the thyroid, adrenal glands, ovaries and testes. Although it may be responsible for these glands, it gets its commands from the neighbor's hypothalamus. Basically, glands and hormones are a long communication chain in the body.
