Anatomy of the Heart - External and Internal Structures
This video is about the structural anatomy of the heart
Circulation of the heartCirculus Sanguid Minor (Pulmonary circulation):
- Deoxygenated blood comes from the body into the right atrium though superior and inferior vena cava.
- Blood goes through Tricuspid valve into right ventricle
- Right ventricle pumps blood through pulmonary valve into pulmonary artery
- Pulmonary artery pumps blood into the lungs
Circulus Sanguis major (Systemic Circulation):
- Blood comes from the lungs into the left Atria
- Left atria sends blood through bicuspid valve into the left ventricle.
- Left ventricle sends blood through the Aortic Valve into the Aorta
- Aorta sends blood to the body again
External Structures of the heart
- Apex Cordis directed anteriorly to the left
- Basis Cordis directed backwards to the right.
Three surfaces fo the heart:
- Facies pulmonalis
- Facies Sternocostalis
- Facies Diaphragmatica
Strictures on the surface of the heart:
- Margo Dexter between Facies Sternocostalis and Facies Diaphragmatica
- Sulcus Coronarius separates Atria from Ventricles
- Sulcus Interventricularis anterior and posterior.
Internal Septum:
- Septum Cordis separates right side from left side.
- Septum interventriculare (Muscular part and Membranous part)
- Septum Interatriale
Internal structures of the heart
Walls of the Right Atrium (Strictures):
- Anterior Wall: Auricula Dextra (Pectinate Muscle)
- Lateral Wall: Musculus Pectinati
- Superior Wall: Ostium Vena Cava Superior
- Between Superior and Inferior Vena Cava is the Sinus Venarum Cavarum (Sinus Venosum) separated from pectinate muscle by a crest on outside called Crista Terminalis
- Posterior Wall: Ostrium Vena Cava Inferior, Vulva vena cava inferioris (Inferior Vena Caval valve)
- Medial Wall: Septum Interatriale, Fossa Ovale (Foramen Ovale) Limbus Fossa Ovale, Ostium Sinus Coronarii, Vulva SInus Coronarii, Foramina Venarum Minimarum.
- Inferior Wall: Ostium Atrioventriculare Dextrum, guarded by the tricuspid valve.
Strictures of the Right Ventricle:
- Rough inner layer; Trabeculae Carneae
- Musculi Papillares
Base of the right ventricle:
Tricuspid Valve: Septal Cusp, Anterior cusp and posterior cusp formed by endocardium
- Surrounded by anulus fibrosus
- Chordae Tendinae attached to musculi pappilares.
Pulmonary Valve:
- Also has Anulus Fibrosus
- Has Noduli Vulva Semilunaris (Nodules of the Semilunar valve)
- Sinus Trunci Pulmonares (Pulmonary Sinus)
- Three Semilunar Cusps
Walls of the Left Atrium:
- Anterior Wall: Auricula Sinister (Has Musculi Pectinati)
- Posterior Wall: Pulmonary Veins (has 4 openings called ostia ventarum pulmonalium, openings of the pulmonary veins)
- Medial Wall: Septa interatriale
- Inferior Wall: Ostium Atrioventriculare sinister
Structures of the left ventricle:
Base of the ventricle:
- Ostium Atrioventriculare Sinister guarded by Bicuspid Valve (Mitral Valve)
- Bicuspid Valve has two big cusps or leaflets called cuspis anterior and cuspis posterior. But it also has Commissural Cusps.
- Ostium Aorta (in Vestibulum Aortae)
- Vulva Aortae (three semilunar valve)
- Has Aortic Sinuses and Aortic Nodules
- Trabeculae Carneae
- Musculi Papillares
