Correct Answer » C Explanation

A – oral sebaceous (Fordyce) gland

B – duct of oral sebaceous gland

• This is a section through a Fordyce spot (A).
• These glands are simple alveolar and have a holocrine mode of secretion.
• Note their similarity to the sebaceous glands associated with hair follicles.
• The cells arise in the base of the gland and begin to produce an oily product – sebum.
• The accumulation of sebum eventually kills the cell and it is secreted as a sac of oil through the duct (B).
