Human Skin

Quick Answer: The human skin model is a three-dimensional section of skin, shown greatly enlarged as skin models are, that displays the epidermis, dermis and subcutaneous tissue together with hair follicles, glands, blood vessels and nerve endings. Biology and nursing students use it to identify skin structures and link each one to its job.

Reading the Layers of the Skin

A skin model is usually a block cut through the skin so that its side faces show the layers in section. At the top, the epidermis is a stratified epithelium: new cells form in the basal layer and are pushed outwards, filling with keratin, until they reach the surface as the flat, dead cells of the stratum corneum that are constantly shed. Melanocytes in the basal layer supply the pigment melanin.

Below lies the dermis, the thick connective-tissue layer that gives skin its strength and elasticity. Its upper papillary layer forms ridges that interlock with the epidermis and hold capillary loops and touch receptors, while the deeper reticular layer contains hair follicles, the sebaceous glands that open into them, coiled sweat glands and the small arrector pili muscles. The subcutaneous layer, or hypodermis, is mostly fat that insulates and cushions.

Some models show hairy skin on one part of the block and thicker, hairless skin on another, but that is not stated for this listing. The 3D skin model on stand in the same range is an alternative for display at the front of a class.

Specifications

Applications

• Labelling skin structures in secondary biology and in the integumentary unit of nursing courses
• Relating burn depth to skin layers in first-aid and nursing lessons
• Showing where intradermal and subcutaneous injections are placed
• Comparing the model with a prepared slide of skin under the microscope

Care & Handling

• Keep the human skin model upright on its base; lying on its side can crack small projecting hair shafts.
• Clean the painted section faces with a dry brush, since moisture can soften printed labels.
• Store it away from heaters and direct sun.

Why Choose LabEquip

Nursing schools and biology departments use a skin model to connect textbook layers with structures students can point at. LabEquip includes it in its biology lab products and also supplies prepared slides for comparing the model with real tissue. Send your enquiry through the contact page.

Frequently Asked Questions

What are the three main layers of the skin?

The epidermis is the outer epithelial layer, the dermis beneath it is dense connective tissue with vessels, nerves and glands, and the subcutaneous layer, or hypodermis, is mainly fat. Strictly, only the first two are skin; the hypodermis lies beneath it.

How does the epidermis get oxygen and nutrients without blood vessels?

Being avascular, the epidermis relies on substances diffusing up from the capillary loops in the dermal papillae beneath it. This is also why a shallow graze confined to the epidermis does not bleed.

What does the arrector pili muscle do?

It is a tiny smooth muscle attached to the hair follicle. When it contracts, usually in cold or fear, it pulls the hair upright and raises the skin around it, producing goosebumps.

What is the difference between sweat glands and sebaceous glands?

Sweat glands produce watery sweat that cools the body as it evaporates and usually open directly onto the surface. Sebaceous glands produce oily sebum that softens hair and skin, and they open into hair follicles.

How does the model help explain burns?

Burns are described by depth. A superficial burn affects the epidermis, a partial-thickness burn reaches into the dermis, and a full-thickness burn destroys both layers, including the nerve endings the model shows in position.

Is a skin model better than a microscope slide?

They complement each other. The model shows all the structures in three dimensions at a size a class can see, while a stained slide shows real cells. Many teachers use the model first and the slide afterwards.
