The hexacanth embryo of tapeworm on getting into the host bores into

Options

A. The muscles
B. Blood stream
C. Heart
D. Wall of alimentary canal

Answer

To answer the question regarding where the hexacanth embryo of a tapeworm bores into upon entering the host, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Hexacanth Embryo**: The hexacanth embryo is the larval stage of the tapeworm (Tinea) that has six hooks. This structure is crucial for its attachment to the host's tissues.

2. **Entry into the Host**: The hexacanth embryo enters the host after the ingestion of tapeworm eggs. Once inside the host, it is typically found in the alimentary canal.

3. **Location of Attachment**: Upon entering the alimentary canal, the hexacanth embryo uses its six hooks to attach itself to the wall of the elementary canal (the intestines).

4. **Nutritional Absorption**: After attaching to the wall of the elementary canal, the hexacanth embryo derives its nutrition from the host's digestive system.

5. **Development into Cysticercus**: As the hexacanth larva grows, it eventually develops into another larval form known as the cysticercus, which can migrate to other tissues, but initially, it remains attached to the intestinal wall.

6. **Conclusion**: Therefore, the hexacanth embryo of the tapeworm bores into the wall of the elementary canal of the host.

### Final Answer:
The hexacanth embryo of the tapeworm bores into the wall of the elementary canal.
