"Melanopsin" Natural Recordings by Native Speakers
Melanopsin is a type of photoreceptor that is sensitive to blue light and is involved in non-visual responses to light, such as regulating circadian rhythms, controlling the sleep-wake cycle, and influencing mood and behavior. It is found in the retinal ganglion cells of the eye and is responsible for responding to the presence or absence of light, allowing the body to synchronize its internal clock with the day-night cycle.
Melanomatosis is a rare type of skin cancer that is characterized by the widespread growth of malignant melanocytes, which are the cells that produce the pigment melanin, in various parts of the body, often in the skin, mucous membranes, and eyes.
Melanomic refers to something related to or characterized by melanoma, which is a type of cancer that arises from pigment-producing cells called melanocytes. In a medical context, melanomic can describe a tumour or a malignant growth that is caused by the abnormal proliferation of melanocytes. It can also refer to a treatment or therapy that targets melanoma or melanocytes.
Melanonychia is a medical term that refers to the pigmentation of the nails, where the nails have a brown or black coloration. This can be caused by various factors, including injury to the nail bed, fungal infections, certain medical conditions, or exposure to certain chemicals.
A melanophore is a type of cell found in the skin of many animals, including humans, that plays a crucial role in the production of melanin, the pigment responsible for skin and hair color. In other words, melanophores are the cells that help to determine an individual's natural hair and skin color.
Melanophores are specialized cells found in the skin of certain animals, particularly fish and reptiles, that contain pigment granules. These granules are responsible for changing the color of the skin in response to hormonal changes, environmental stimuli, or emotional states. In other words, melanophores help regulate the coloration of an animal's skin, allowing it to adapt to its surroundings, express its emotional state, or communicate with other animals of the same species.
Melanorrhoea refers to a disease characterized by dark-colored urine, often caused by the presence of melanin in the urine.
A melanosome is a type of organelle found in melanocytes, which are cells that produce the pigment melanin. Melanosomes are responsible for the production and storage of melanin, the pigment that gives color and protects the skin from harmful ultraviolet rays.
Melanosomes are membrane-bound organelles found in melanocytes, the cells responsible for producing melanin, a pigment responsible for skin and hair color. They are the site of melanin synthesis and accumulation, and are involved in the transfer of melanin to keratinocytes, the cells that make up the outermost layer of the epidermis, to provide protection against ultraviolet radiation.
Melanostatin is a neuropeptide hormone that specifically inhibits the release of melanin-producing melanocytes, thereby controlling melanocyte activity and regulating skin and hair pigmentation.
Melanotaenia is a genus of freshwater fish, often referred to as rainbowfish. It is a common name for a group of small, colorful fish that are native to rivers and streams in Australia, New Guinea, and parts of Southeast Asia. The name "Melanotaenia" comes from the Greek words "melanos," meaning black, and "tenos," meaning stretched, likely due to the distinctive black stripe that runs along the length of their bodies. These fish are popular aquarium species due to their vibrant colors and active swimming behavior.
Melanotic refers to something that is related to or resembling melanin, a pigment found in skin, hair, and eyes. In medicine, melanotic typically describes a type of tumor or cyst that produces melanin, often causing skin discoloration or darkening. In a broader sense, it can also describe the dark or darkened appearance of a substance, such as a melanotic fungus.
