Pineal gland notes
The pineal gland, conarium, or epiphysis cerebri, is a small endocrine gland in the brain of most vertebrates. The pineal gland produces melatonin, a serotonin-derived hormone which modulates sleep patterns in both circadian and seasonal cycles. The shape of the gland resembles a pine cone, which gives it its name. The pineal gland is located in the epithalamus, near the center of the brain, between the two hemispheres, tucked in a groove where the two halves…

Carbazochrome is an antihemorrhagic or hemostatic agent
Carbazochrome is an antihemorrhagic, or hemostatic, agent that will cease blood flow by causing the aggregation and adhesion of platelets in the blood to form a platelet plug, ceasing blood flow from an open wound. It is hoped that this drug can be used in the future for preventing excessive blood flow during surgical operations and the treatment…

Digestive enzymes
Digestive enzymes are a group of enzymes that break down polymeric macromolecules into their smaller building blocks, in order to facilitate their absorption into the cells of the body. Digestive enzymes are found in the digestive tracts of animals (including humans) and in the tracts of carnivorous plants, where they aid in the digestion of food, as well as inside cells,…

CD31
Platelet endothelial cell adhesion molecule (PECAM-1) also known as cluster of differentiation 31 (CD31) is a protein that in humans is encoded by the PECAM1gene found on chromosome17q23.3.[5][6][7][8] PECAM-1 plays a key role in removing aged neutrophils from the body. Structure PECAM-1 is a highly glycosylated protein with a mass of approximately 130 kDa.[9] The structure of this protein was determined by molecular cloning in 1990, when it was…

Leydig cells aka interstitial cells of the testes and interstitial cells of Leydig
Leydig cells, also known as interstitial cells of the testes and interstitial cells of Leydig, are found adjacent to the seminiferous tubules in the testicle and produce testosterone in the presence of luteinizing hormone (LH).[1][2] They are polyhedral in shape and have a large, prominent nucleus, an eosinophiliccytoplasm, and numerous lipid-filled vesicles.[3] Structure The mammalian Leydig cell is a polyhedral epithelioid cell with a single eccentrically located ovoid nucleus.…
