internal urethral sphincter
|
UBERON_0004918 |
[A urethral sphincter muscle which constricts the internal urethral orifice. It is the junction of the urethra with the urinary bladder. The muscle is made of smooth muscle, so therefore it is under involuntary control. It is kept tonically contracted by the sympathetic nervous system and during micturition, is relaxed via the parasympathetic nervous system. This is the primary muscle for preventing the release of urine[WP].] |

|
UBERON_0004915 |
[Muscular valve that controls the flow of digestive juices (bile and pancreatic juice) through the ampulla of Vater into the second part of the duodenum. Relaxed by the hormone Cholecystokinin (CCK) via vasoactive intestinal polypeptide (VIP).[WP].] |

|
supraorbital bone
|
UBERON_2000691 |
[Dermal bone that is part of the dorsal or upper border or antero-dorsal border of the orbit. The supraorbital bone may contact the orbital margin of the frontal bone medially, the antorbital antero-ventrally and the dermosphenotic posteriorly.
