irregular connective tissue
The dermis or corium is a layer of skin between the epidermis (with which it makes up the cutis) and subcutaneous tissues, that primarily consists of dense irregular connective tissue and cushions the body from stress and strain.

What type of connective tissue makes up the dermis quizlet?

What types of tissues make up the dermis? The papillary layer is areolar connective tissue, and the reticular layer is dense irregular connective tissue. Blood vessels, smooth muscle tissue, and nervous tissue are found in the dermis.

Where is skin the thickest?

palms of the hands
Epidermis varies in thickness throughout the body depending mainly on frictional forces and is thickest on the palms of the hands and soles of the feet, and thinnest in the face (eyelids) and genitalia.

What is the most common connective tissue in the dermis?

The most common connective tissue is collagen.

What is found in the dermis quizlet?

What types of tissues cells are found in the dermis quizlet?

What types of tissues/cells are found in the dermis? capillaries, nerves, glands, and hair follicles.

What is the thickest layer of skin?

The squamous cell layer is the thickest layer of the epidermis, and is involved in the transfer of certain substances in and out of the body.

Where is the thinnest skin on human body?

Skin is thickest on the palms and soles of the feet (1.5 mm thick), while the thinnest skin is found on the eyelids and in the postauricular region (0.05 mm thick).

Does the dermis contain connective tissue?

The dermis is a connective tissue layer sandwiched between the epidermis and subcutaneous tissue. The dermis is a fibrous structure composed of collagen, elastic tissue, and other extracellular components that includes vasculature, nerve endings, hair follicles, and glands.

What are the 4 main types of connective tissues?

Connective Tissue

  • Loose Connective Tissue.
  • Dense Connective Tissue.
  • Cartilage.
  • Bone.
  • Blood.

What is found in the dermis?

The dermis houses blood vessels, nerve endings, hair follicles, and glands. There are many cell types found within the connective tissue of the dermis, including fibroblasts, macrophages, adipocytes, mast cells, Schwann cells, and stem cells. [5] Fibroblasts are the principal cell of the dermis.

What are the two layer of the dermis?

The dermis has connective tissue, blood vessels, oil and sweat glands, nerves, hair follicles, and other structures. It is made up of a thin upper layer called the papillary dermis, and a thick lower layer called the reticular dermis.

What connects the dermis to the subcutaneous tissue?

Other components of the subcutaneous tissue include: Fibrous bands: to anchor the skin to the deep fascia Collagen and elastin fibers: to connect the subcutaneous tissue to the dermis Lymphatic vessels: to connect the dermis to the lymphatic system Nerves: to connect the dermis and free nerve endings in the subcutaneous tissue to the nervous system
