### Step-by-Step Solution:

1. **Understanding the Uterine Cycle**:
- The uterine cycle in women is also known as the menstrual cycle. It involves a series of physiological changes that prepare the uterus for potential pregnancy.

2. **Identifying Key Hormones**:
- The menstrual cycle is regulated by various hormones produced by the brain and the ovaries. The primary hormones involved are estrogen and progesterone.

- Menstruation
- Follicular phase
- Ovulation
- Luteal phase
