Answer:
The correct answer is - option A. IKK.
Explanation:
In signal transduction or any other molecular biology process, the upstream or downstream is related to the molecular or cellular events that follow a mechanistic and temporal order.
In TNF signaling involved in cell survival pathway the TRADD- associated complex also is known as TNF receptor-associated death domain complex has a second messenger that activates temporally after the cell membrane receptor known as IKK signaling protein that help in numerous downstream pathways.
Thus, the correct answer is - option A. IKK.
<u>Answer</u>: Infundibulum, ampulla, isthmus, uterus.
<u>Explanation</u>:
- The ovary produces the egg and, it releases one unfertilized egg every month.
- The egg then travels through the fallopian tube to the uterus.
- The fallopian tube consists of three parts:
1. <em>Infundibulum</em>- it is the most distal portion of the fallopian tube which receives the egg coming out of the ovary.
2. <em>Ampulla</em>- This is the next portion of the fallopian tube which is ciliated and is the site of fertilisation of the egg.
3. <em>Isthmus</em>- it is also a ciliated region which controls the transport of both sperm and the embryo.
- Finally, after passing through the isthmus the fertilized egg reaches the uterus where implantation takes place.
- <em>So the journey of the egg from the ovary to uterus follows the pathway, ovary---> infundibulum--->ampulla--->isthmus--->uterus.</em>
