head of femur
|
UBERON_0006767 |
[The hemispheric articular surface at the upper extremity of the thigh bone[Stedman, 26th ed]. The femur head is the highest part of the thigh bone. It is supported by the neck of the femur. The head is globular and forms rather more than a hemisphere, is directed upward, medialward, and a little forward, the greater part of its convexity being above and in front. Its surface is smooth, coated with cartilage in the fresh state, except over an ovoid depression, the fovea capitis femoris, which is situated a little below and behind the center of the head, and gives attachment to the ligament of head of femur. If there is a fracture of the neck of the femur, the blood supply through the ligament becomes crucial. In orthopedic surgery, the head of the femur is important because it can undergo avascular necrosis and consequent osteochondritis dissecans. The head is removed in total hip replacement surgery [WP].] |

|
anterior communicating artery
|
UBERON_0006764 |
[A blood vessel of the brain that connects the left and right anterior cerebral arteries. The anterior communicating artery connects the two anterior cerebral arteries across the commencement of the longitudinal fissure. Sometimes this vessel is wanting, the two arteries joining together to form a single trunk, which afterward divides; or it may be wholly, or partially, divided into two. Its length averages about 4 mm, but varies greatly. It gives off some of the anteromedial ganglionic vessels, but these are principally derived from the anterior cerebral artery. It is part of the cerebral arterial circle, also known as the circle of Willis.] |

branch of anterior cerebral artery
|
UBERON_0035380 |
[An arterial branch arising from the anterior cerebral artery. It includes the callosomarginal artery, frontopolar artery, medial orbitofrontal artery, pericallosal artery, and recurrent artery of Heubner.] |
|
chorionic trophoblast cell
|
CL_0011101 |
[Cells of the uterine chorion that acquire specialized structural and/or functional features that characterize chorionic trophoblasts. These cells will migrate towards the spongiotrophoblast layer and give rise to syncytiotrophoblasts of the labyrinthine layer.] |
|
trophoblast cell
|
CL_0000351 |
[An extraembryonic cell that develops from a trophectodermal cell. This cell is found in the outer layer of the blastocyst and can invade other structures in the uterus once the blastocyst implants into the uterine wall. A trophoblast cell is involved in the implantation of the embryo into the uterine wall, placental formation, remodelling of maternal vasculature in the uterus, nutrient and gas exchange, hormone production, and immune modulation to support fetal development.] |
