What is the source of melanocyte-stimulating hormone?
the pituitary gland
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.
Where is Alpha MSH produced?
the pituitary
α-MSH is produced predominantly by melanotrope cells in the intermediate lobe of the pituitary, particularly in species such as the rat and mouse. The adult human pituitary does not have a distinct intermediate lobe and therefore this is not a source of α-MSH in humans.
Do humans have melanocyte-stimulating hormone?
Although the melanocyte-stimulating hormone (MSH) is well-recognised as a pigmentary hormone in animals, its role in human pigmentation is still a matter for conjecture, not least because cultured human melanocytes have proved to be relatively refractory to the peptide.
Does MSH darken skin?
There are two main reasons for this. First, despite the observations in the 1960s that alpha-MSH increased skin darkening in humans, there are reports that the peptide has no effect on melanogenesis in cultured human melanocytes.
Where are the melanocytes found?
epidermis
A cell in the skin and eyes that produces and contains the pigment called melanin. Anatomy of the skin, showing the epidermis, dermis, and subcutaneous tissue. Melanocytes are in the layer of basal cells at the deepest part of the epidermis.
Where is follicle stimulating hormone secreted from?
pituitary gland
FSH is made by your pituitary gland, a small gland located underneath the brain. FSH plays an important role in sexual development and functioning. In women, FSH helps control the menstrual cycle and stimulates the growth of eggs in the ovaries.
Which part of pituitary gland secretes MSH?
pars intermedia
Explanation: Melanocyte stimulating hormone (MSH) is secreted by the pars intermedia or middle lobe of the pituitary gland. It is one of the two parts of the adenohypophysis of the pituitary gland. MSH stimulates the synthesis and secretion of melanin from melanocytes.
Can I change my skin Colour?
It is impossible to change your constitutional skin tone. However, it is possible to medically treat concerns like tan, dark spots and post-acne pigmentation with safe and effective skin lightening solutions. These advanced aesthetic treatments can improve the health of your skin and restore its natural glow.

What are melanocytes made of?
Melanocyte is a highly differentiated cell that produces a pigment melanin inside melanosomes. This cell is dark and dendritic in shape. Melanin production is the basic function of melanocyte. With the process of differentiation this cell loses the proliferative potential.
What organs have melanocytes?
Melanocytes are pigment-producing cells of vertebrates. They are found in the integument, the eye, the inner ear, and, depending on the species, also in a variety of other inner organs, such as the lung, the heart, and around the aorta.
Which gland produces melanin?
The occurrence of melanin has been described in the pineal gland of some mammal species, but the reports are scarce [11, 14, 16–20]. This suggests that melanin is not a constant characteristic in the pineal gland of mammals. The biological significance of this pigment in the gland has not been clearly determined.
