Scala vestibuli is connected with

Options

A. foramen ovale
B. scala media
C. scala tympani
D. fenestra rotunda

Answer

**Step-by-Step Solution:**

1. **Understanding Scala Vestibuli**: The Scala vestibuli is one of the three fluid-filled chambers in the cochlea of the inner ear. It plays a crucial role in the process of hearing.

2. **Identifying Connections**: We need to identify what the Scala vestibuli connects to. The options provided are:
- A) Fenestra rotunda (round window)
- B) Scala media
- C) Scala tympani
- D) Fenestra ovalis (oval window)

3. **Analyzing Each Option**:
- **Option A (Fenestra rotunda)**: This is known as the round window, which is part of the middle ear, but it does not connect directly to the Scala vestibuli.
- **Option B (Scala media)**: This is the middle chamber of the cochlea, also known as the cochlear duct, but it is not the direct connection of the Scala vestibuli.
- **Option C (Scala tympani)**: This is the lower chamber of the cochlea and is indeed connected to the Scala vestibuli.
- **Option D (Fenestra ovalis)**: This is known as the oval window, which connects the middle ear to the inner ear, but it is not a direct connection to the Scala vestibuli.

4. **Conclusion**: The Scala vestibuli is connected with the Scala tympani. Therefore, the correct answer is **Option C: Scala tympani**.
