Options

A. Cutting plates
B. Lancets
C. Sucking action of pharynx
D. Surface spicules

Answer

To answer the question "Hookworm holds the intestinal wall by means of," we will analyze the options provided and determine the correct one step by step.

### Step-by-Step Solution:

1. **Understanding Hookworm Anatomy**:
- Hookworms are parasitic nematodes that attach to the intestinal wall of their host (humans) to feed on blood.

2. **Examining the Options**:
- **Cutting Plates**: These are not present in hookworms. They are associated with other types of parasitic worms.
- **Lancets**: These are specialized structures that hookworms possess. They are located in the buccal cavity and are used to anchor the worm to the intestinal wall.
- **Sucking Action of Pharynx**: While the pharynx does play a role in feeding, it is not the primary means by which the hookworm attaches to the intestinal wall.
- **Surface Spicules**: These are structures found in male nematodes for reproductive purposes, not for attachment to the intestinal wall.

3. **Identifying the Correct Answer**:
- Given the analysis of the options, the correct answer is **lancets**. Hookworms use these structures to hold onto the intestinal wall.

4. **Conclusion**:
- Therefore, the hookworm holds the intestinal wall by means of **lancets**.
