Caecum is small blind sac which hosts some symbiotic micro-organisms. From it a small finger like vestigeal organ arises. This organ is called -

Options

A. Parotid gland
B. Vermis
C. Vermiform appendix
D. Lacteals

Answer

**Step-by-Step Solution:**

1. **Understanding the Cecum**: The cecum is a small, blind sac located at the beginning of the large intestine. It plays a role in the digestive system by hosting symbiotic microorganisms.

2. **Role of Microorganisms**: The microorganisms present in the cecum are primarily symbiotic bacteria. These bacteria help in the digestion of cellulose, which is a component of plant material that is difficult for the human digestive system to break down.

3. **Identification of the Finger-like Organ**: From the cecum, there arises a small, finger-like projection. This projection is a vestigial organ, meaning it has lost most or all of its original function through the course of evolution.

4. **Naming the Organ**: The finger-like projection that arises from the cecum is called the "Vermiform Appendix." It is termed "vermiform" because it resembles a worm in shape.

5. **Conclusion**: Therefore, the organ that arises from the cecum and is considered vestigial is the Vermiform Appendix.

**Final Answer**: The organ is called the Vermiform Appendix.
