desmosomes
The stratum basale and the stratum spinosum together are called the epidermis.
Tonofilaments first appear in the stratum spinosum layer of the epidermis, specifically in the keratinocytes. These filaments play a key role in cell adhesion and strengthening the skin barrier.
In this layer, cells start to round up like little balls. The name stratum spinosum refers to the spiny architecture that occurs as the cells change shape, dehydrate, and protrude into the other layers.dehydrate and
Weblike prekeratin filaments first appear in the basal layer of the epidermis, which is the innermost layer of the skin. These filaments eventually differentiate into keratinocytes as they migrate towards the surface of the skin.
The stratum spinosum is a layer of the epidermis that provides strength and flexibility to the skin. It contains cells called keratinocytes that produce keratin, a protein that helps protect the skin from damage. The stratum spinosum also plays a role in the skin's immune response.
desmosomes
The layer of the skin that contains spine-like projections to hold cells tightly together is the stratum spinosum. This layer is located above the stratum basale and is characterized by the presence of desmosomes, which are intercellular junctions that resemble spines and provide structural support. The stratum spinosum plays a crucial role in the skin's strength and flexibility.
The stratum spinosum, also known as the "prickly layer," is a layer of the epidermis located above the stratum basale and below the stratum granulosum. Its primary function is to provide strength and flexibility to the skin due to the presence of desmosomes, which are intercellular junctions that connect keratinocytes. Additionally, the stratum spinosum contains Langerhans cells, which play a role in immune responses by detecting pathogens and alerting the immune system. Overall, it contributes to the protective barrier of the skin.
Desmosomes hold a lot more than just the above together. See Gap Junctions.
Gastrolobium spinosum was created in 1839.
Citharexylum spinosum was created in 1753.
Insulanoplectron spinosum was created in 1970.
Cells are pushed into the stratum spinosum from the stratum basale. The stratum spinosum is the layer above the stratum basale in the epidermis and contains more differentiated keratinocytes.
stratum spinosum
the cell to cell structures that hold the cells of the stratum spinosum together when they shrink are called desmosomes.
The epidermal layer just interior to the stratum granulosum is the stratum spinosum. This layer is composed of living keratinocytes that help provide strength and structure to the skin. The stratum spinosum is important for cell turnover and the production of keratin.
