Is located beneath the epidermis?
The dermis, found beneath the epidermis, contains connective tissue, hair follicles, blood vessels, lymphatic vessels, and sweat glands. The deeper subcutaneous tissue (hypodermis) is made of fat and connective tissue.
What lies beneath the epidermis Khan Academy?
Although, it’s technically not skin, but it’s called the “hypodermis.” This is the hypodermis, which is a great name because as you might recall, hypo just means “below” and this layer sits right below the dermis. Another name for it is subcutaneous fat, and I think that that’s also a great name for what we have here.
What is the layer under the skin called?
Three layers of tissue make up the skin: Epidermis, the top layer. Dermis, the middle layer. Hypodermis, the bottom or fatty layer.
Which is the deepest layer of the epidermis?
stratum basale
The layers of the epidermis include the stratum basale (the deepest portion of the epidermis), stratum spinosum, stratum granulosum, stratum lucidum, and stratum corneum (the most superficial portion of the epidermis).
What is the layer beneath the dermis?
hypodermis layer
The layer of skin beneath the dermis is sometimes called the subcutaneous fat, subcutis, or hypodermis layer. This layer provides insulation for your body, keeping you warm.

What are the five layers of epidermis?
The epidermis layer itself is made up of five sublayers that work together to continually rebuild the surface of the skin:
- The Basal Cell Layer.
- The Squamous Cell Layer.
- The Stratum Granulosum & the Stratum Lucidum.
- The Stratum Corneum.
- The Papillary Layer.
- The Reticular Layer.
What is under the skin layer?
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 deepest layer of skin?
1. Stratum Basale or Basal Layer. The deepest layer of the epidermis is called the stratum basale, sometimes called the stratum germinativum.
What are the skin layers in order?
Three layers of tissue make up the skin:
- Epidermis, the top layer.
- Dermis, the middle layer.
- Hypodermis, the bottom or fatty layer.
What is the anatomy of the epidermis?
Anatomy of the Epidermis. Within the epidermis, there are four major layers of cells (called keratinocytes) that provide the skin its structural supports, as well as one layer specific to the soles and palms. Keratinocytes within the epidermis begin dividing in the bottom layer, pushing already formed cells into the upper layer.
What is the boundary between the epidermis and dermis called?
The boundary between the epidermis and dermis is histologically conspicuous and usually wavy. The upward waves are fingerlike extensions of the dermis called dermal papillae and the downward epidermal waves between the papillae are called epidermal ridges.
Why is the epidermis found on the palms and soles?
Most of the barrier functions of the epidermis localize to this layer. This narrow layer is found only on the palms and soles. The epidermis of these two areas is known as “thick skin” because with this extra layer, the skin has 5 epidermal layers instead of 4.
What is the deepest layer of the epidermis?
The deepest epidermal layer is the stratum basale or stratum germinativum. This single layer of cells is firmly attached to the basal lamina, which separates the epidermis from the loose connective tissue of the adjacent dermis. Large stem cells, termed basal cells, dominate the stratum basale.
