Question

Extended exposure to salon products without proper precautions can affect all of the following epithelial tissues EXCEPT

a) skin
b) cartilage
c) mouth lining
d) respiratory organs

Answer 1

Cartilage is not affected by extended exposure to salon products as it is not an epithelial tissue and is less exposed to external substances. Epithelial tissues such as skin, mouth lining, and respiratory organs are at risk due to their direct exposure to the environment.

Step-by-step explanation:

Extended exposure to salon products without proper precautions can affect several types of epithelial tissues due to the harsh chemicals which may irritate or damage them. These tissues include the skin, mouth lining, and the epithelium of the respiratory organs. The one that would not be affected is cartilage as it is not an epithelial tissue, and since it does not have a direct exchange with the external environment, it is less likely to be exposed to these products. Cartilage is a type of connective tissue that is found in joints, the rib cage, ear, nose, bronchial tubes, and intervertebral discs. This tissue is more avascular and lacks nerve structures which further reduces its exposure to topical substances like salon products compared to the mucosal and epidermal layers.

Answering the question related to the body cavities exposed to the external environment, the lining referred to as mucosa is the correct choice. It includes a variety of epithelial tissues such as the epidermal surface, mucosal epithelium, and glands, which are exposed to the outside world and line the outside of organs. Systems lined by an epithelium include the airways, the digestive tract, the urinary, and the reproductive systems.

Answer 2

Cartilage is not affected by salon products as it is a type of connective tissue and not an epithelial tissue like skin, mouth lining, or respiratory organs which are exposed to external substances.

Step-by-step explanation:

The question asks which epithelial tissues are affected by extended exposure to salon products, except one. The tissues that are typically exposed and can be affected include skin, mouth lining, and respiratory organs. These areas are lined with epithelium that protects the body and can interact with or absorb substances. Cartilage, however, is not an epithelial tissue; it is a type of connective tissue that lacks a direct supply of blood and is not typically exposed to external substances in the same way as epithelial tissues. Therefore, the correct answer to the question is b) cartilage. In contrast, skin epithelium provides mechanical damage and ultraviolet light protection, while mucosal epithelium lines the inside of the mouth and the respiratory system.
