Granulosa cells
Granulosa Cells
Granulosa cells (pronounced: gran-yoo-LOH-suh cells) are a type of somatic cell found in the ovary. They are involved in the production of sex hormones during the menstrual cycle and the maturation of the ovum.
Etymology
The term "granulosa" comes from the Latin word "granulum", which means "small grain". This is in reference to the grain-like appearance of these cells under a microscope.
Function
Granulosa cells play a crucial role in the development and maturation of the oocyte during the menstrual cycle. They secrete estrogen and progesterone, hormones that are essential for the regulation of the menstrual cycle and pregnancy. They also provide physical support to the developing oocyte and form the structure of the corpus luteum after ovulation.
