Do we really have seven layers of skin?
Do you ever take time to think about how many layers that you have? Do we have three or seven layers of skin? Well we kind of have both amounts. Read on for more information.
There are three main layers if skin but there are layers within two of these layers. One of these layers is the epidermis; the epidermis is the top external layer and has five layers within that layer. The next layer is the dermis; the dermis has two layers within its layer. Then there is the last layer this layer is the hypodermis, the hypodermis is mostly fat and it has no layers within that layer.
The epidermis has five layers within that layer. The first two layers within the epidermis are called the stratum corundum and the next layer is the stratum lucidum, this is only in thick skin like the palms of your hands and the sole of your foot. Another two layers within the epidermis is the stratum gramnulosum and the stratum spiosum. The last layer within the epidermis is the stratum germinativum. These are the layers within the epidermis.
The dermis has two layers within its layer. The first layer in the dermis is the dermal papillary layer. The next layer within the dermis is the dermal reticular layer; this layer is the location of a lot of structures such as the hair follicles and the blood vessels. These are the layers within the dermis.
