Neurogenic heart is characteristic of

Options

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

Answer

**Step-by-Step Solution:**

1. **Understanding the Types of Hearts**: There are two main types of hearts: myogenic and neurogenic. Myogenic hearts are controlled by the heart muscles themselves, while neurogenic hearts are controlled by the nervous system.

2. **Defining Myogenic Heart**: Myogenic hearts are characterized by contractions that are initiated by cardiac muscles. They do not rely on signals from other organs to beat, which makes them easier to transplant.

3. **Defining Neurogenic Heart**: Neurogenic hearts, on the other hand, have their contractions controlled by the nervous system. They rely on a structure known as a ganglion that receives signals from the nervous system and transmits impulses to the heart.

4. **Characteristics of Neurogenic Heart**: Neurogenic hearts are unable to function once removed from the body, making them difficult to transplant. This type of heart is typically found in lower invertebrates.

5. **Identifying Organisms with Neurogenic Hearts**: Based on the characteristics of neurogenic hearts, they are primarily found in invertebrates such as arthropods. In contrast, myogenic hearts are found in vertebrates, including humans, rats, and rabbits.

6. **Conclusion**: Therefore, the neurogenic heart is characteristic of invertebrates.

**Final Answer**: Neurogenic heart is characteristic of invertebrates.
