|
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 |
