Eustachian tube is present between :

Options

A. Inner ear & larynx
B. Middle ear & pharynx
C. Outer ear & pharynx
D. Middle ear & larynx

Answer

**Step-by-Step Solution:**

1. **Understanding the Eustachian Tube**: The Eustachian tube, also known as the auditory tube, is a canal that connects the middle ear to the nasopharynx (the upper part of the throat behind the nose).

2. **Analyzing the Options**:
- **Option 1: Inner ear and larynx**: This option is incorrect because the inner ear is not connected to the Eustachian tube, and the larynx (voice box) is not part of the pathway for the Eustachian tube.
- **Option 2: Middle ear and pharynx**: This option is correct. The Eustachian tube connects the middle ear to the nasopharynx.
- **Option 3: Outer ear and pharynx**: This option is incorrect because the outer ear does not connect to the pharynx via the Eustachian tube.
- **Option 4: Middle ear and larynx**: This option is also incorrect as the Eustachian tube connects the middle ear to the nasopharynx, not the larynx.

3. **Conclusion**: Based on the analysis of the options, the correct answer is that the Eustachian tube is present between the middle ear and the pharynx.

**Final Answer**: The Eustachian tube is present between the middle ear and the pharynx.
