What are the similarities and differences in the epidermis and dermis?
Dermis and epidermis are basically protective outer layers of the body. The main difference between dermis and epidermis is that dermis is a tissue below the epidermis, containing living cells whereas epidermis is the outermost part of the body, protecting it from dehydration, trauma, and infections.
What do the epidermis and the dermis have in common?
A number of components are common to both the dermis and epidermis. These are: pores, hair, sebaceous glands, and sweat glands. Pores are formed by a folding-in of the epidermis into the dermis. At the base of each hair is a bulb-like follicle that divides to produce new cells.
What is the structural relationship between the epidermis dermis and hypodermis?
The epidermis consists of several layers The topmost layer consists of dead cells that shed periodically and is progressively replaced by cells formed from the basal layer. The dermis connects the epidermis to the hypodermis, and provides strength and elasticity due to the presence of collagen and elastin fibers.
How are hypodermis dermis similar?
The deepest layer of the skin is called the subcutaneous layer, the subcutis, or the hypodermis. Like the dermis, the layer contains blood vessels and nerves for much the same reasons. Importantly, the subcutis contains a layer of fat.
What are the differences between the epidermis dermis and hypodermis?
The main difference between epidermis and hypodermis is that epidermis is the outer protective layer of the skin of vertebrates, covering the dermis, whereas hypodermis is the subcutaneous tissue found in the lowermost layer of the skin.
What is one difference between the dermis and the epidermis?
The epidermis is the outermost layer among the three layers of the skin in an organism. The dermis is the layer of the skin just below the epidermis. Blood vessels are not present in the epidermis. Blood vessels, which are a tiny network of blood capillaries, are present in the dermis.
What is the difference between epidermis dermis and hypodermis?
The epidermis, the outermost layer of skin, provides a waterproof barrier and creates our skin tone. The dermis, beneath the epidermis, contains tough connective tissue, hair follicles, and sweat glands. The deeper subcutaneous tissue (hypodermis) is made of fat and connective tissue.
What is the difference between the dermis and the epidermis quizlet?
Distinguish between the epidermis and dermis. Outer epidermis is made up of stratified squamous epithelium, and the inner dermis is thicker than the epidermis and made up of CT with collagen and elastic fibers, smooth muscle, nervous tissues, and blood. Describe and define the functions of the subcutaneous later.
Where is the epidermis and dermis located in relationship to each other?
Where is the epidermis and dermis located in relationship to each other? The epidermis is the outermost layer of the skin. The dermis is the second layer of the skin and located between the epidermis and the subcutaneous tissue.
Which layer of the epidermis is closest to the surface?
stratum basale
The stratum basale, also called the stratum germinativum, is the basal (base) layer of the epidermis. It is the layer that’s closest to the blood supply lying underneath the epidermis.
What is the major difference between the epidermis and the dermis of the skin quizlet?
Distinguish between the epidermis and dermis. Outer epidermis is made up of stratified squamous epithelium, and the inner dermis is thicker than the epidermis and made up of CT with collagen and elastic fibers, smooth muscle, nervous tissues, and blood.
How does the structure of the dermis differ from the structure of the epidermis?
The skin layer of the epidermis does not contain blood vessels. Epidermis gets the nourishment and oxygen from the deeper layer that diffuses them upwards. The dermis has a fragile network of vessels known as capillaries which are densely located under the epidermis. The epidermis layer does not have nerves.
