Granulosa cell
Granulosa Cell
Granulosa cells (pronounced: gran-yuh-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", meaning "small grain". This refers to the appearance of these cells in the ovary.
Function
Granulosa cells play a crucial role in the development and maturation of the ovum. They surround the developing oocyte in the follicle, providing it with necessary nutrients and signals. These cells also produce sex hormones, including estrogen, in response to Follicle Stimulating Hormone (FSH) from the pituitary gland.
