Purkinje cells are found in

Options

A. Cerebral cortex
B. Cerebellar cortex
C. mammalian heart
D. Semicircular canal

Answer

**Step-by-Step Solution:**

1. **Understanding Purkinje Cells**:
- Purkinje cells are a type of neuron that plays a critical role in the functioning of the brain. They are large, multipolar neurons found in specific regions of the brain.

2. **Identifying the Location**:
- To determine where Purkinje cells are located, we need to consider the various parts of the brain. The options provided are:
- A. Cerebral cortex
- B. Cerebellar cortex
- C. Mammalian heart
- D. Semicircular canal

3. **Analyzing the Options**:
- **Cerebral Cortex**: This is the outer layer of the brain involved in higher brain functions such as thought and action. Purkinje cells are not found here.
- **Cerebellar Cortex**: This is the outer layer of the cerebellum, which is responsible for coordination and balance. Purkinje cells are indeed located here.
- **Mammalian Heart**: This organ is responsible for pumping blood and does not contain Purkinje cells.
- **Semicircular Canal**: This structure is part of the inner ear and is involved in balance but does not contain Purkinje cells.

4. **Conclusion**:
- Based on the analysis, Purkinje cells are specifically found in the cerebellar cortex, which is part of the hindbrain. Therefore, the correct answer is **Option B: Cerebellar Cortex**.

**Final Answer**: Purkinje cells are found in the Cerebellar Cortex.
