A vertebra having flat surface both in front and behind is
(a) Acoelous
(b) Procoelous
(c) Amphicoelous
(d) Amphiplatyon

Options

A. Acoelous
B. Procoelous
C. Amphicoelous
D. Amphiplatyon

Answer

To determine the type of vertebra that has a flat surface both in front and behind, we can analyze the options provided:

1. **Understanding the Types of Vertebrae**:
- **Acoelous Vertebra**: These vertebrae have flat surfaces on both ends (front and back). They do not have any concavity.
- **Procoelous Vertebra**: These vertebrae have a concave surface at the front and a flat or slightly convex surface at the back.
- **Amphicoelous Vertebra**: These vertebrae have concave surfaces at both ends.
- **Amphiplatyon Vertebra**: This term is not commonly used in standard vertebral classification.

2. **Identifying the Correct Answer**:
- Since the question specifies that the vertebra has flat surfaces both in front and behind, we can conclude that the correct answer is **Acoelous**.

Thus, the answer to the question is:
**(a) Acoelous**
