Comparative anatomy — snake venom glands: The poison glands of snakes are homologous to which glands in other vertebrates? Identify the correct homologous structure. Choose the correct option.

Difficulty: Easy

Salivary glands
Lachrymal glands
Sebaceous glands
Adrenal glands

Correct Answer: Salivary glands

Explanation:

Concept / Approach
Snake venom glands are modified salivary glands; they share developmental origin and ductal connection to the fangs for venom delivery.

Elimination
Lachrymal (tear), sebaceous (oil), and adrenal (endocrine) glands are not homologous to venom glands.

Final Answer
Salivary glands.
