Many drugs can be applied to the skin without entering the blood. how is this fact explained?
ra1l [238]

*A drug administered by the cutaneous route can have one of these three actions:

Local action, superficial: ex. local anesthetic ...

Deep action: ex. anti-inflammatory action ...

Systemic or general action: ex. anti-anginal action

*The skin is a very effective barrier, which limits the number of drugs that can enter the system.

*The factor influencing the penetration of the drugs are:

- Nature and physicochemical properties of P.A: Molecular weight, hydrophilicity, lipophilicity, stability ...

- Formulation of the drug: Excipients lipophilic, hydrophilic, amphiphilic, an absorption promoter

- Nature and condition of the skin, Location, age, thickness (1 to 8 mm ...), vascularization...

*To not penetrate the skin, a drug should have to be of high molecular mass (to be unable to penetrate through the skin tissue), hydrophilic (since the skin is of a lipophilic nature).

*For example, solar creams should not enter the system so the excipients used are hydrophilic in nature.

Stels [109]

Answer:

The answer is the 2nd picture: the coccyx bone in humans.

Explanation:

Vestigial Structure:

Structures or anatomical features that do not currently serve a function is the bodily processes of a living organism. Vestiges are believed to have performed active functions in the organism's ancestors throughout its evolutionary history.

Coccyx Bone:

The coccyx or tailbone is an evolutionary remnant of our tree dwelling ancestors. Coccyx has no use in modern humans as we do not need to climb trees.

The coccyx in modern humans serves as an anchor for muscles.
