BIOL 2114 Lecture Notes - Lecture 1: Mesovarium, Reproductive System, Labia Minora
Document Summary
Ovarian l: anchors ovary medially to uterus. Suspensory l: anchors ovary laterally to pelvic wall. Eggs need support & do not touch anything. Mesovarium & suspensory l are part of broad l. Medulla: contains large blood vessels & nerves. Both rich blood supply to provide constant nurishment to ovaries. Houses an immature ova (oocyte) that"s surrounded by: Follicle cells (if only 1 cell layer is present) Granulosa cells (if more than 1 layer is present) Follicles go through several stages of development: Primary follicle: single layer of cells surrounding oocyte, becomes secondary. Secondary follicle: (more mature) 2 or more layers surrounding oocyte, becomes vesticular. Graafian/vesicular follicle: (mature) a fluid-filled antrum forms, isolating oocyte. Follicle is sitting on stalk of cells to support it & Serval eggs go through this process at the same time to push it out. Fsh & lh are elevated at birth but drop low until prepubertal years.
