Ovary - Corpus Luteum
Histology image shows the ovary in overview, the cortex and medulla of the ovary can be clearly seen.
Corpus luteum (yellow body) theca lutein cells and granulosa lutein cells. These cells work together in the production of ovarian hormones that support the initial pregnancy.
Corpus albicans (white body) lack of implantation and associated hCG will lead to this structure not producing hormones.
Atretic follicles are the degenerating follicles from various developmental stages that did not form the ovulating follicle and do not form the corpus luteum.

Cardiovascular System Development - Heart Tube Segments
As the tubular heart grows it develops dilations and constrictions which form the truncus arteriosus, bulbus cordis, primitive ventricle, primitive atrium and sinus venosus.

“Certainly the primary imperative of a physician is to be skilled in medical science, but if he or she does not probe a patient’s soul, then the doctor’s care is given without caring, and part of the sacred mission of healing is missing.” — Jerome E. Groopman

Pancreatic Cancer
Palladin Expression in Primary Cultures of Pancreatic Ductal Cells Derived from Increasingly Neoplastic Samples. Expression of Palladin RNA increases relative to the degree of precancer to cancer: normal to PanIN 1 (hyperplasia) to PanIN 3 (carcinoma in situ) to cancer. Each bar represents epithelial cell cultures from one person. The PanIN 1 and PanIN 3 lesions (lower left photomicrograph) were purified from two affected members of Family X. The pancreatic cancer epithelial cells (lower right photomicrograph) were purified from a sample of sporadic adenocarcinoma.
