Question Abraham tried to match the modified sweat glands and sebaceous glands with their functions in the human body.
He tabulated two pairs as follows:
| Glands | Functions |
|---|---|
| P | Lubricate the margins of the eyelids. |
| Q | Protect the delicate eardum from dust particles and germs. |
Identify the correct pair of glands.
- P — Meibomian glands, Q — Salivary glands
- P — Ceruminous glands, Q — Meibomian glands
- P — Salivary glands, Q — Ceruminous glands
- P — Meibomian glands, Q — Ceruminous glands
P — Meibomian glands, Q — Ceruminous glands
Reason — Meibomian glands are modified sebaceous glands located along the margins of the eyelids. Their function is to secrete an oily substance that lubricates the eyelids.
Ceruminous glands are modified sweat glands found in the ear canal. They produce cerumen (earwax), which traps dust and germs, protecting the delicate eardrum.
