However, there are differences between the biology of melanophores and that of melanocytes. In addition to eumelanin, melanocytes can generate a yellow/red pigment called phaeomelanin. [citation needed] The purple-striped dottyback, Pseudochromis diadema, generates its violet stripe with an unusual type of chromatophore.
Fish and frog melanophores are cells that can change colour by dispersing or aggregating pigment-containing melanosomes. A melanosome is an organelle found in animal cells and is the site for synthesis, storage and transport of melanin , the most common light-absorbing pigment found in the animal kingdom .
The human brain. Differences in male and female brain size are relative to body size. [85] Early research into the differences between male and female brains showed that male brains are, on average, larger than female brains. This research was frequently cited to support the assertion that women are less intelligent than men.
Illustration of a melanocyte Micrograph of melanocytes in the epidermis. Through a process called melanogenesis, melanocytes produce melanin, which is a pigment found in the skin, eyes, hair, nasal cavity, and inner ear. This melanogenesis leads to a long-lasting pigmentation, which is in contrast to the pigmentation that originates from ...
“Estrogen, particularly estradiol, the strongest form, plays a critical role in the brain’s health and functionality, earning it the title of the ‘master regulator’ of women’s brain health.
Gross anatomy (also called topographical anatomy, regional anatomy, or anthropotomy) is the study of anatomical structures that can be seen by the naked eye. [1] Microscopic anatomy is the study of minute anatomical structures assisted with microscopes , which includes histology (the study of the organization of tissues), [ 1 ] and cytology ...
Well, according to Wise, the brain is actually the most powerful sex organ there is—namely because genital stimulation produces so much muscle and nerve information that a tremendous boost in ...
One average square inch (6.5 cm 2) of skin holds 650 sweat glands, 20 blood vessels, 60,000 melanocytes, and more than 1,000 nerve endings. [5] [better source needed] The average human skin cell is about 30 μm in diameter, but there are variants. A skin cell usually ranges from 25 to 40 μm 2, depending on a variety of factors.
