Zygomatic arch of rabbit (mammals) is formed of

Options

A. Maxilla, periotic and jugal
B. Maxilla, squamosal and jugal
C. Maxilla, pre-maxilla and squamosal
D. Periotic, jugal and palatine.

Answer

### Step-by-Step Text Solution:

1. **Understanding the Zygomatic Arch**: The zygomatic arch, commonly known as the cheekbone, is a bony structure that forms the prominence of the cheek. It plays a crucial role in the structure of the face and is involved in the attachment of facial muscles.

2. **Identifying the Bones Involved**: The zygomatic arch in mammals, including rabbits, is formed by the fusion of several bones. The primary bones involved in forming the zygomatic arch are:
- **Maxilla**: This is the upper jawbone and contributes significantly to the zygomatic arch.
- **Zygomatic Bone (also known as Jugal Bone)**: This bone directly forms the arch itself.
- **Squamous Part of the Temporal Bone**: This part of the temporal bone also contributes to the zygomatic arch.

3. **Analyzing the Options**: Given the options provided in the question:
- **Option 1**: Maxilla, Periodic, Jugal - Incorrect
- **Option 2**: Maxilla, Squamous, Jugal - Correct
- **Option 3**: Maxilla, Premaxilla, Squamous - Incorrect
- **Option 4**: Preperiodic, Jugal, Palatine - Incorrect

4. **Conclusion**: The correct answer is **Option 2: Maxilla, Squamous, Jugal**. These three bones together form the zygomatic arch in rabbits.
