Detailed explanation-1: -The intermediate lobe of the pituitary (also called pars intermedia ) produces MSH, or melanocyte-stimulating hormone which acts on melanocytes or pigment-producing cells responsible for the colour of our skin and iris of the eyes.

Detailed explanation-2: -Melanocyte-stimulating hormone describes a group of hormones produced by the pituitary gland, hypothalamus and skin cells. It is important for protecting the skin from UV rays, development of pigmentation and control of appetite.

Detailed explanation-3: -The intermediate lobe synthesizes and secretes melanocyte-stimulating hormone (MSH). It stimulates the production and release of melanin by melanocytes in skin and hair.

Detailed explanation-4: -The most obvious function of the pars intermedia in lower vertebrates is the secretion of melanocyte-stimulating hormone (MSH) for the purpose of pigmentary control.

Detailed explanation-5: -Middle lobe of pituitary secretes MSH(melanocyte stimulating hormone) that controls the synthesis of melanin granules in the chromatophores.
