Are the oldest epidermal cells found in the stratum basale?
Yes, the oldest epidermal cells are found in the stratum basale. This layer, also known as the basal layer, is the deepest layer of the epidermis and is responsible for the continuous production of new cells. As cells are pushed upwards, they become older and eventually reach the outermost layer of the epidermis, the stratum corneum, where they are shed.
What is the structure of the skin?
The skin consists of three main layers: the epidermis, dermis, and hypodermis. The epidermis is the outermost layer and contains protective keratinized cells. The dermis is the middle layer and contains blood vessels, nerves, hair follicles, and sweat glands. The hypodermis is the innermost layer and is composed of fat cells for insulation and cushioning.
Explain the concept of relative age?
Relative age refers to determining the age of a rock layer or fossil relative to another by examining their position in the rock record. This method does not provide an exact numerical age, but it helps in establishing the sequence of events and determining which layer is older or younger. Relative age dating relies on principles like superposition, cross-cutting relationships, and the law of faunal succession.
Weather is affected by this important substance?
Weather is primarily affected by the atmosphere, a layer of gases surrounding Earth. The composition and interactions of gases like water vapor, carbon dioxide, and methane in the atmosphere influence the weather patterns we experience, including temperature, precipitation, and wind. Additionally, factors such as the Earth's rotation, solar radiation, and geography play a role in shaping weather systems.
What does gilden age mean?
"Gilded Age" refers to a period in American history (late 19th century) characterized by rapid economic growth, industrialization, and wealth accumulation, particularly among the upper class. The term also implies a superficial layer of prosperity that masks underlying social issues like income inequality, political corruption, and labor exploitation.
What layer consists of melanin granules and dendritic cells?
These are found in the basal layer of the dermis. There are two types of the pigment melanin: eumelanin, a group of dark brown (almost black) melanins and peomelanin, a group of reddish and orange melanins.
What pigment is found in the granular layer of the skin?
melanin
Where are pigment cells located in the body?
Pigment cells (melanocytes) are found in the basal layer of the epidermis.
What body part is Pigment cells located?
Pigment cells (melanocytes) are found in the basal layer of the epidermis.
A black pigment found in the epidermis is?
Epidermal pigment is pigment that is on the outer layer of the skin. In humans, that is usually melanin, which is the pigment that makes up skin.
What are different between colorful eyes and dark eyes when born?
There is no major difference, its just that dark eyes have Iris with a dark pigment layer. Its not that the other colorful eyes don't have the pigment layer, they do but because the color of pigment layer differ therefore color of eye differ. Blue eyes don't have pigment.
Where are pigments located in the human body?
Pigment cells (melanocytes) are found in the basal layer of the epidermis.
Why are boto dolphins pink?
This is not because of pigment but because of a thick layer of blood vessels beneath the skin.
Does the stratum corneum contain melanin?
No. They are found in the lowest layer of the epidermis (stratum basale)No. They are found in the lowest layer of the epidermis (stratum basale).
What pigment is phagocytized by keratinocytes?
Melanocytes phagocytize melanin. First, melanocytes which are present in the lowest or basal layer of the epidermis, produce the pigment melanin. The melanin forms granules called melanosomes. After the keratinocytes take up the pigment, it clusters around the keratinocyte nucleus on the superficial side. This protects the DNA in the keratinocyte nucleus from damage due to UV radiation.
In which layer of the epidermis are granules of keratohyalin formed?
stratum granulosum
