Middle ear has

Options

A. Malleus
B. Choroid
C. Odontoid process
D. Malpighian cells.

Answer

To answer the question "Middle ear has," we need to identify the correct option from the given choices. Here’s a step-by-step solution:

### Step 1: Identify the Components of the Middle Ear
The middle ear is an anatomical structure that plays a crucial role in hearing. It contains three small bones known as the ear ossicles.

### Step 2: Recognize the Ear Ossicles
The three ear ossicles in the middle ear are:
1. Malleus (also known as the hammer)
2. Incus (also known as the anvil)
3. Stapes (also known as the stirrup)

### Step 3: Determine the Correct Answer
Among the options provided, the malleus is specifically mentioned as being part of the middle ear. It is the largest of the three ear ossicles and is crucial for transmitting sound vibrations from the outer ear to the inner ear.

### Step 4: Analyze the Other Options
- **Choroid**: This is the middle layer of the eye, not related to the middle ear.
- **Odontoid Processes**: These are projections from the second cervical vertebra (the axis) and are not related to the ear.
- **Malthesian Cells**: These are cells found in the innermost layer of the mammalian skin, also unrelated to the ear.

### Conclusion
The correct answer to the question "Middle ear has" is **the malleus**.
