In the brain, tissues with melanin include the medulla and pigment-bearing neurons within areas of the brainstem, such as the locus coeruleus. It also occurs in the zona reticularis of the adrenal gland. [18] The melanin in the skin is produced by melanocytes, which are found in the basal layer of the epidermis. Although, in general, human ...
Neuromelanin gives specific brain sections, such as the substantia nigra or the locus coeruleus, distinct color. It is a type of melanin and similar to other forms of peripheral melanin. It is insoluble in organic compounds, and can be labeled by silver staining. It is called neuromelanin because of its function and the color change that ...
Pigmentation including tanning is under hormonal control, including the MSH and ACTH peptides that are produced from the precursor proopiomelanocortin. Vitiligo is a skin disease where people lack melanin in certain areas in the skin. People with oculocutaneous albinism typically have a very low
The melanocyte-stimulating hormones, known collectively as MSH, also known as melanotropins or intermedins, are a family of peptide hormones and neuropeptides consisting of α-melanocyte-stimulating hormone (α-MSH), β-melanocyte-stimulating hormone (β-MSH), and γ-melanocyte-stimulating hormone (γ-MSH) that are produced by cells in the pars intermedia of the anterior lobe of the pituitary ...

As for the orgasm connection, oxytocin is produced in the hypothalamus (i.e., the control center of the brain), which is yet another region activated—both in the posterior and anterior—during ...
MCH is a cyclic 19-amino acid neuropeptide, as it is a polypeptide chain that is able to act as a neurotransmitter.MCH neurons are mainly concentrated in the lateral hypothalamic area, zona incerta, and the incerto-hypothalamic area, but they are also located, in much smaller amounts, in the paramedian pontine reticular formation (PPRF), medial preoptic area, laterodorsal tegmental nucleus ...
Vitamin D3 is produced when the skin is exposed to sunlight and found in animal-based foods. ... vitamin D can protect heart and brain health and fight inflammation. ... Melanin can also affect ...
