Anatomical terminology [ edit on Wikidata ] The crista terminalis (also known as the terminal crest , [ citation needed ] or crista terminalis of His [ 1 ] ) is a vertical ridge on the [ 2 ] : 56 posterolateral [ 3 ] inner surface of the adult right atrium extending between the superior vena cava , and the inferior vena cava .
But we’ll keep the more anatomical heart for reference. So this vessel, the ductus arteriosus, usually closes after birth because the walls collapse down and it becomes a ligament—the ligamentum arteriosum— when it stays open after birth, we call it a patent ductus arteriosus because it’s still passing blood through it, in other words ...
The arching horizontal racemes of up to 20 pendent flowers are borne in spring and early summer. The outer petals are bright fuchsia-pink, while the inner ones are white. The flowers strikingly resemble the conventional heart shape, with a droplet beneath – hence the common name. [4]
An adorable way to honor a best friend or loved one is to get matching tattoos. These subtle tattoos use white ink instead of the traditional black for a striking effect. Image credits: @_tan_tattoo
The heart is a muscular organ situated in the mediastinum.It consists of four chambers, four valves, two main arteries (the coronary arteries), and the conduction system. The left and right sides of the heart have different functions: the right side receives de-oxygenated blood through the superior and inferior venae cavae and pumps blood to the lungs through the pulmonary artery, and the left ...
Anatomical terminology [ edit on Wikidata ] The infundibulum (also known as conus arteriosus ) is a conical pouch formed from the upper and left angle of the right ventricle in the chordate heart , from which the pulmonary trunk arises.
Here’s the normal heart, with upper chambers, the left and the right atria, and lower chambers, the left and the right ventricles, as well as the aorta and the pulmonary artery. Instead of using this anatomical heart though, I’m going to use actually use this simplified version of the heart instead.
It is an anatomical area located at the base of the right atrium, and its boundaries are the coronary sinus orifice, tendon of Todaro, and the septal leaflet of the right atrioventricular valve (also known as the tricuspid valve). [2] It is anatomically significant because the atrioventricular node is located at the apex of the triangle. The ...
