Unveiling the Layers of the Epidermis

Learning Objective

At the end of the lesson, you will be able to demonstrate the layers which make up the epidermis.

What do you already know about the layers of the epidermis?

Introduction to Epidermis

The epidermis is the outermost layer of the skin, serving as a protective barrier.

Layers of the Epidermis

The epidermis consists of five layers: stratum corneum, stratum lucidum, stratum granulosum, stratum spinosum, and stratum basale.

Stratum Corneum

The outermost layer composed of dead skin cells that protect against external elements.

Stratum Lucidum

A thin, translucent layer found only in thick skin areas like the palms and soles.

Stratum Granulosum

Consists of cells that produce keratin, a protein essential for skin strength and water resistance.

Stratum Spinosum

Also known as the prickle cell layer, providing strength and flexibility to the skin.

Stratum Basale

The deepest layer where new skin cells are formed and constantly pushed towards the surface.

Write down 3 things you learned in this lesson.

Have students enter three things they learned in this lesson. With this they can indicate their own learning efficiency of this lesson.

Write down 2 things you want to know more about.

Here, students enter two things they would like to know more about. This not only increases involvement, but also gives them more ownership.

Ask 1 question about something you haven't quite understood yet.

The students indicate here (in question form) with which part of the material they still have difficulty. For the teacher, this not only provides insight into the extent to which the students understand/master the material, but also a good starting point for the next lesson.
