Involved in smooth muscle contraction (milk letdown, parturition).
Derived from granulosa cells. They increase in size (hypertrophy) and contain receptors for PGF2 . They produce P4 and Oxytocin.
Below is a summarized study guide based on the core topics covered in this curriculum, including reproductive anatomy, hormone production, and cellular function.
Examining what different species lack in their reproductive tracts is a common exam focus: Does not have an Ampulla .
Derived from theca cells. They increase in number (hyperplasia) and contain receptors for LH. They are primarily responsible for P4 production. 4. Comparative Anatomy (Species Differences)
In ruminants, these cells migrate from the trophoblast to the maternal epithelium:
This theory explains how estrogen is synthesized in the follicle via the cooperation of two distinct cell types:
Maintains pregnancy; produced by large and small luteal cells. Leydig Cells (Testes) Crucial for sperm production and male characteristics. Oxytocin Large Luteal Cells / Hypothalamus
