Fordyce’s Granules Oral cavity arise from –
**Core Concept**
Fordyce's granules are small, yellowish or whitish bumps that appear on the lips, inside the cheeks, and sometimes on the genital area. They are ectopic sebaceous glands, meaning they are sebaceous glands that have formed in an abnormal location.
**Why the Correct Answer is Right**
Fordyce's granules arise from the ectopic sebaceous glands, which are formed from the sebaceous glands of the skin. These glands are responsible for producing sebum, an oily substance that helps to lubricate and protect the skin. In the case of Fordyce's granules, the sebaceous glands have formed in an abnormal location, such as the oral cavity, where they can produce sebum that can be noticeable as small, yellowish or whitish bumps.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because Fordyce's granules do not arise from mucous glands. Mucous glands are responsible for producing mucus, a thick, protective substance that helps to lubricate and protect the mucous membranes.
**Option B:** This option is incorrect because Fordyce's granules do not arise from salivary glands. Salivary glands are responsible for producing saliva, a watery substance that helps to break down food in the mouth.
**Option C:** This option is incorrect because Fordyce's granules do not arise from lymphoid tissue. Lymphoid tissue is responsible for producing immune cells, such as lymphocytes, that help to fight infection.
**Clinical Pearl / High-Yield Fact**
Fordyce's granules are often seen in individuals with a family history of the condition, and they can be more noticeable in individuals who are taking certain medications, such as testosterone or estrogen. They are usually harmless and do not require treatment, but they can be a source of concern for some individuals.
**Correct Answer: D. Ectopic sebaceous glands.
