bipolar

Explanation:

Neurons are highly excitable cells that communicate with each other or with other effector cells, using basically electrical language. Most neurons have three regions responsible for specialized functions: cell body, dendrites, and axons.

Most neurons have several dendrites and one axon, so they are called multipolar. But there are also bipolar and pseudo unipolar neurons. In bipolar neurons, two extensions leave the cell body, one dendrite and one axon.

"menstrual cycle is a complex cycle that consists of several processes. order of occurrence of steps in menstrual cycle are as follows:

1. high progesterone levels maintain the endometrium lining of the uterus.

2. endometrium lining breaks down and low levels of estrogen stimulate the pituitary to release fsh and lh.

3. fsh and lh stimulates the follicles to develop and the oocyte to produce estrogen.

4. rising estrogen levels suppress fsh production and development of other follicles.

5. a spike in lh causes follicle to rupture.

6. a breakdown of corpus luteum causes progesterone level to drop."
