Based on the provided reference, the answer depends on the location in the body. Here's a breakdown:
The question is a bit ambiguous because peristalsis occurs in multiple locations and involves different hormones. Therefore, let's clarify by addressing peristalsis in both the alimentary canal and the uterine walls.
Hormones Involved in Peristalsis
| Location | Hormone(s) Involved |
|---|---|
| Alimentary Canal | Gastrin |
| Uterine Walls | Oxytocin, Estrogen |
Gastrin in the Alimentary Canal
- Gastrin stimulates peristalsis in the alimentary canal.
- This helps move food through the digestive system.
Oxytocin and Estrogen in the Uterine Walls
- Oxytocin and Estrogen stimulate peristalsis in the uterine walls. This is particularly important during labor to facilitate childbirth.
Therefore, to summarize:
- In the alimentary canal, gastrin helps in peristalsis.
- In the uterine walls, oxytocin and estrogen help in peristalsis.
