13 Cards in this Set

  • Front
  • Back
Tricuspid complex:
This structure includes
• Tricuspid valve
• Right atrioventricular (AV) fibrous ring.
• Chordae tendineae
• Papillary muscles
The above structures of the heart prevent blood in the right ventricle from flowing back into the right atrium.
Bicuspid complex:
This structure includes
• Bicuspid valve
• Left atrioventricular (AV) fibrous ring.
• Chordae tendineae
• Papillary muscles
The above structures of the heart prevent blood in the left ventricle from flowing back into the left atrium.
Atrioventricular (AV) crux:
It is a superficial mark on the heart and a point of junction of the following 3 grooves:
• Coronary groove
• Inter-artrial groove
• Posterior inter-ventricular groove
Arterial Ligament
The fibrous cord that connects the left pulmonary arteries and the arch of aorta. It develops from the embryonic arterial duct (called ductus arteriosus) in fetus.
Carotid sinus
A slight dilation (expansion) at the origin of the internal carotid artery. It is a pressure receptor that is a part of the blood pressure regulating mechanism.
Carotid body
A chemoreceptor located in the angle between the bifurcations (fork/division into 2) of common carotid artery.
Superficial palmer arch
It is an arterial arch that is formed predominantly by the ulnar artery, with a contribution from the superficial palmar branch of radial artery.
Deep palmer arch
It is an arterial arch that is formed predominantly by the terminal part of the radial artery, with a contribution from the deep palmar branch of ulnar artery. It is about 2cm more proximal than the superficial palmer arch.
Venous angles
The angles formed by the junction of the internal jugular and subclavian veins. The angles are behind the sternoclavicular joint and the lymphatic ducts open at these angles.
Cisterna chyli
It is a dilated sac at the lower end (beginning) of the thoracic duct.
It makes up the lymphatic route from the abdomen to lower limbs. //not sure about this pt.
The intestinal lymphatic trunk and right and left lumbar lymphatic trunks drain into it.
Located at the level of first lumbar vertebrae (L1).
Composition of Angiology:
Angiology is the study of
• Cardiovascular system and
which includes
 Heart
 Blood vessels
which include
• Arteries
• Capillaries and
• Veins
• Lymphatics
which includes
 Lymph vessels
 Lymph organs
 Lymph tissues
Blood flow direction of systemic (greater) circulation:
• Left ventricle
• → Aorta
• → Branches of arteries
• → Capillaries
• → Branches of veins
• → Superior and Inferior vena cava //kinda like a pipe that passes thru the side of heart
• → Right atrium
Blood flow direction of pulmonary (lesser) circulation:
• Right ventricle
• → Pulmonary arterial trunk //main pulmonary arterial
• → Branches of the pulmonary arteries
• → Pulmonary capillaries
• → Pulmonary veins
• → Left atrium
