The correct Answer is:
To determine the type of vertebra that has convexity both in front and behind, we can analyze the options provided: 1. **Achiolus**: This type of vertebra has convexity on both the anterior (front) and posterior (back) ends. It is commonly found in most mammals. 2. **Prochilus**: This vertebra has a concave anterior end and a convex posterior end. It is typically found in frogs and reptiles. Therefore, this option does not fit the description. 3. **Amphiocilus**: This type of vertebra is characterized by a spindle shape and is found in fish and amphibians. The notochord runs through the center of this vertebra. Hence, this option is also incorrect. 4. **Amphiplaton**: This vertebra is flat on both sides and is commonly found in humans. It does not have convexity on both ends, making this option incorrect as well. Based on the analysis, the correct answer is **Achiolus**, as it is the only vertebra with convexity both in front and behind. ### Step-by-Step Solution: 1. Identify the characteristics of each type of vertebra listed in the question. 2. Analyze the features of Achiolus, Prochilus, Amphiocilus, and Amphiplaton. 3. Determine which vertebra has convexity on both ends. 4. Conclude that Achiolus is the correct answer since it fits the description provided in the question.
