Which of the Following is Not Considered an Appendix of the Skin

Question

Which of the following is not considered an appendix of the skin?
A) the nails
B) the tongue
C) sweat-producing glands
D) sensory cells that respond to pain

Accepted Answer

The tongue is not an appendix of the skin. It is an organ in the oral cavity that is involved in taste, speech, and swallowing. The nails, sweat-producing glands, and sensory cells that respond to pain are all considered appendages of the skin, as they are structures that arise from the skin and play important roles in its function.
