Which organ is oval in shape ,has a dense covering, and lies in extra-abdominal pouch having two 2 to 1.5 degree centigrade lower temperature than the body?
(a) Ovary
(b) Eyeball
(c) Testis
(d) Epididymis

Options

A. Ovary
B. Eyeball
C. Testis
D. Epididymis

Answer

To solve the question, we need to identify the organ that meets the following criteria:

1. **Oval in shape**: The organ should have an oval shape.
2. **Dense covering**: It should have a dense outer covering.
3. **Lies in an extra-abdominal pouch**: The organ must be located outside the abdominal cavity.
4. **Lower temperature than the body**: The organ should maintain a temperature that is 2 to 1.5 degrees Celsius lower than the normal body temperature.

Now, let's analyze the options provided:

### Step 1: Analyze Each Option
- **(a) Ovary**: The ovary is not oval in shape, and it is located within the abdominal cavity, not in an extra-abdominal pouch.

- **(b) Eyeball**: The eyeball is round, not oval, and is located within the skull, not in an extra-abdominal pouch.

- **(c) Testis**: The testis is oval in shape, has a dense covering (the tunica albuginea), and is located in the scrotum, which is an extra-abdominal pouch. The temperature in the scrotum is indeed lower than the body temperature, typically around 2 to 2.5 degrees Celsius lower, which is essential for spermatogenesis.

- **(d) Epididymis**: The epididymis is not oval; it is a coiled structure attached to the testis and is also located within the scrotum.

### Step 2: Conclusion
Based on the analysis:
- The only organ that fits all the criteria is **(c) Testis**.

### Final Answer
(c) Testis
