Which of the following is NOT a characteristic of the dermis?
topjm [15]

Answer:

A. The dermis lies anterior to the epidermis.

Explanation:

The "Skin" consists of <u><em>three layers:</em></u>

<em>1. Epidermis</em>

<em>2. Dermis</em>

<em>3. Subcutaneous Fat</em>

They are arranged accordingly, which means that the "dermis" lies beneath the epidermis. Therefore, it lies "posterior" or <em>at the back of the epidermis</em>. "Anterior" means<em> "front."</em> The dermis is definitely not anterior to the epidermis. <u>This makes choice A as not a characteristic of the dermis.</u>

<em>Choice B is a characteristic of dermis</em> because the dermis consists of<u> many blood vessels</u> and<u> three types of connective tissue</u><u><em>s</em></u><em> (collagen fibers, elastic fibers and reticular fibers). </em>

<em>Choice C is a characteristic of dermis </em>because it also consists of the<u> lymph vessels, nerves and accessory organs.</u>

<em>Choice D is a characteristic of dermis</em> because the dermis consists of two distinct layers, a superficial layer <em>(papillary dermis</em>) and a deeper layer <em>(reticular dermis). </em>

vovangra [49]

It is especially important to obtain facts about health-related information from a true and credible source for health-related data would mean saving a life of an individual, which is considered to be precious.

Moreover, having a decision or taken an action based from false health-related information is a big risk for your work or profession and the life itself of the person involved.

The consequence may be detrimental and may ruin your own credibility as a health professional. Therefore, obtaining health-related data should come from a credible source and one must use multiple resources in the process of gathering information.
