The neurogenic heart is the characteristic feature of

Options

A. Human
B. Invertebrates
C. Rabbit
D. Rat

Explanation

**Step-by-Step Solution:**

1. **Understand the term "Neurogenic Heart":**
- The term "neurogenic heart" refers to a type of heart that is regulated by the nervous system. This means that the heartbeat is initiated and controlled by nerve impulses.

2. **Identify the options provided:**
- The options given are: human, invertebrate, rabbit, and drake.

3. **Analyze each option:**
- **Human:**
- Humans have a myogenic heart, meaning the heart's contractions are initiated by the heart muscle itself, not by nerve impulses. Therefore, this option is incorrect.
- **Invertebrate:**
- Many invertebrates possess a neurogenic heart, where the heart's rhythm is controlled by the nervous system. This makes this option a strong candidate for the correct answer.
- **Rabbit:**
- Like humans, rabbits also have a myogenic heart. Thus, this option is incorrect.
- **Drake (a type of duck):**
- Similar to humans and rabbits, drakes also have a myogenic heart. Therefore, this option is also incorrect.

4. **Conclusion:**
- Based on the analysis, the only correct option where a neurogenic heart is characteristic is **invertebrates**.

**Final Answer:** The neurogenic heart is a characteristic feature of **invertebrates**.
