What epithelial tissue is affected by acne vulgaris?

What type of epithelial tissue is affected by acne?

Follicular epidermis (epithelium).

In addition to the exposed epidermis of the integumentary surface, the follicular epithelium also contributes to cutaneous barrier functions. Loss of physical barrier integrity sometimes occurs when the intensity of inflammation reduces the strength of the follicular wall.

What layer of skin is affected by acne?

Acne is a chronic disorder of the hair follicles and sebaceous glands located in the middle layer of the skin. In acne, the sebaceous glands are clogged, which leads to pimples and cysts.

What part of the skin does acne vulgaris affect?

How does acne affect the integumentary system?

Development and Effects of Acne

Sebaceous glands become clogged with sebum, a naturally occurring skin oil, and dead skin cells. Bacteria becomes trapped in these clogged follicles, producing pus and inflammation as the immune system attempts to destroy the bacteria.

How many types of epithelial tissues are there?

There are 8 types of epithelial tissues. Simple squamous, Stratified Squamous, Simple Cuboidal, Stratified Cuboidal, Simple Columnar, Stratified Columnar, Pseudostratified Columnar and Transitional epithelia or urothelium.

Which bacteria can cause acne?

The bacterium Propionibacterium acnes is considered a key player in acne development. Studies have shown that P. acnes uses sebum as a source of energy, and its presence in the pores initiates an immune response that triggers inflammation.

What’s the main cause of acne?

What causes acne? Acne is largely a hormonal condition that’s driven by androgen hormones, which typically become active during the teenage and young adult years. Sensitivity to these hormones — combined with surface bacteria on the skin and fatty acids within oil glands — can result in acne.

Which layer of cells in the epidermis contains melanocytes?

The basal cell layer is also known as the stratum germinativum due to the fact that it is constantly germinating (producing) new cells. The basal cell layer contains cells called melanocytes.

Excess production of hormones, specifically androgens, GH, IGF-1, insulin, CRH, and glucocorticoids, is associated with increased rates of acne development. Acne may be a feature in many endocrine disorders, including polycystic ovary disease, Cushing syndrome, CAH, androgen-secreting tumors, and acromegaly.

Is acne white blood cells?

A common type of bacteria that lives on the skin, known as Propionibacterium acnes, sometimes contributes to acne by causing inflammation. The acne signals white blood cells to the area, which damage the tissue and cause an inflammatory response. This causes swelling and infection.
