Question

Complete each sentence by dragging the proper word or phrase into the correct position. Then, place the sentences in order from superficial to deep. stratum basale stratum spinosum stratum lucidum stratum granulosum stratum corneum Drag the text blocks below into their correct order. The next layer is the ___, which is present only on the soles of the feet, hands, fingers and toes. The _ is named for the presence of dark staining keratohyalin granules, which bind the cytoskeletal keratin filaments together. Comprised of viable, cuboidal and columnar cells, the _ contains the keratinocyte stem cells that replenish the exfoliated cells at the surface. The _ is made up of multiple layers of dead keratinocytes that regularly exfoliate. Towards the apical surface, in the ___, the keratinocytes cease cell division, while at the deeper regions, they can still undergo mitosis.

Step 1

The stratum corneum is the outermost layer of the epidermis, consisting of dead keratinocytes that have undergone terminal differentiation and are filled with keratin. Show more…

Drag the text blocks below into their correct order. The next layer is the stratum lucidum which is present only on the soles of the feet, hands, fingers, and toes. The stratum granulosum is named for the presence of dark staining keratohyalin granules, which bind the cytoskeletal keratin filaments together. Comprised of viable, cuboidal, and columnar cells, the stratum granulosum contains the keratinocyte stem cells that replenish the exfoliated cells at the surface. The stratum spinosum is made up of multiple layers of dead keratinocytes that regularly exfoliate. Towards the apical surface, in the stratum corneum, the keratinocytes cease cell division, while at the deeper regions, they can still undergo mitosis.

0:00 Hello everyone.

00:01 So in this question it is describing about the layers of the epidermis.

00:10 So we are here given the layers name of this layer of epidermis and they are proper function or the proper wording.

00:21 So after matching this we have to position these description at the correct position that is from superficial to deep.

00:36 So before going into the question first we learn about the layers of the epidermis.

00:42 So the layers of the epidermis include number one is the stratum basale which is the deepest portion.

00:54 This is the deepest portion of the epidermis.

00:59 Then after that is the stratum spinosum.

01:07 Then third one is the stratum granulosum.

01:14 Fourth one stratum lucidum and fifth one is the stratum corneum which is the most superficial portion of the epidermis.

01:40 Now moving to the question.

01:44 So this is our question we are here given the layers of the epidermis and here we are given the description we have to first the match the layers of epidermis to its correct description.

01:57 So for easy answering i'll mark these description this layers as a number one two three and four.

02:07 So first thing here given is the towards the apical surface in the dash the keratinocytes sees the cell division while at the deeper region they can still undergo mitosis.

02:22 So here the layer involved is the stratum corneum...
