Which of the following is NOT a secretory structure found in the skin?
A
Sebaceous gland
B
Lymph node
C
Ceruminous gland
D
Sudoriferous (sweat) gland
Verified step by step guidance1
Step 1: Begin by understanding the question. It asks which structure is NOT a secretory structure found in the skin. Secretory structures in the skin are responsible for producing and releasing substances such as oils, sweat, or other secretions.
Step 2: Review the listed options: Sebaceous gland, Lymph node, Ceruminous gland, and Sudoriferous (sweat) gland. Identify which of these are secretory structures associated with the skin.
Step 3: Recall the functions of each structure: Sebaceous glands secrete sebum (oil), Ceruminous glands produce earwax (cerumen), and Sudoriferous glands secrete sweat. These are all secretory structures found in the skin.
Step 4: Understand the role of lymph nodes. Lymph nodes are part of the immune system and are not secretory structures. They filter lymph and house immune cells but do not produce or release substances onto the skin.
Step 5: Conclude that the correct answer is 'Lymph node,' as it is not a secretory structure found in the skin, unlike the other options provided.
