Mark the incorrect statement

Options

A. The ear ossicle attached to tympanic membrane is Mallelus
B. Opsin (of Rhodopsin, develops from vitamin A
C. The pressure on ear drum is equalized by Eustachian tube
D. Otolith organ consists of saccule and utricle

Answer

**Step-by-Step Solution:**

1. **Identify the Statements:** We have four statements to analyze:
- Statement 1: The ear ossicle attached to the tympanic membrane is the malleus.
- Statement 2: Opsin of rhodopsin develops from vitamin A.
- Statement 3: The pressure on the eardrum is equalized by the Eustachian tube.
- Statement 4: The otolith organ consists of sacculi and utricle.

2. **Analyze Statement 1:** The malleus is indeed the ear ossicle that is attached to the tympanic membrane (eardrum). This statement is correct.

3. **Analyze Statement 2:** Opsin is a protein that combines with retinal to form rhodopsin, which is found in rod cells of the retina. Retinal is derived from vitamin A, not opsin. Therefore, this statement is incorrect.

4. **Analyze Statement 3:** The Eustachian tube (also known as the auditory tube) helps to equalize the pressure on either side of the eardrum. This statement is correct.

5. **Analyze Statement 4:** The otolith organs, which are part of the vestibular apparatus in the inner ear, indeed consist of the sacculi and utricle. This statement is correct.

6. **Conclusion:** The incorrect statement among the four provided is Statement 2: "Opsin of rhodopsin develops from vitamin A."

**Final Answer:** Statement 2 is incorrect.
