Posterior wall of the right atrium:
• Opening of the superior vena cava
• Opening and valve of the inferior vena cava
• Opening and valve of the coronary sinus
• Fossa ovalis and the limbus fossa ovalis
Anterior wall of the right atrium:
• Pectinate muscles
• Crista terminalis
Right Atrium

Right Ventricle
![Page 9: Internal features of Heart Dr. Sama ul Haque. Objectives List the chambers of the heart. Describe the internal features of right atrium. Describe](https://reader036.vdocument.in/reader036/viewer/2022062515/56649c9e5503460f9495e020/html5/thumbnails/9.jpg)
• Tricuspid valve has three cusps: anterior, septal, and posterior.• Three papillary muscles: anterior, septal, and posterior. The
anterior papillary muscle is the largest and most prominent.
• Trabeculae carneae (rough muscular ridges).
Right Ventricle
![Page 10: Internal features of Heart Dr. Sama ul Haque. Objectives List the chambers of the heart. Describe the internal features of right atrium. Describe](https://reader036.vdocument.in/reader036/viewer/2022062515/56649c9e5503460f9495e020/html5/thumbnails/10.jpg)
• The septomarginal trabecula (moderator band): extends from the interventricular septum to the base of the anterior papillary muscle.
• The conus arteriosus (infundibulum): is the cone-shaped portion of the right ventricle inferior to the opening of the pulmonary trunk.
• The pulmonary valve: consists of three semilunar cusps: anterior, right, and left.
Right Ventricle

Left Atrium• Receives blood from
lungs: Through 4 pulmonary veins (2 right & 2 left)
• Bicuspid valve: blood passes through it into left ventricle (mitral valve has two cusps).
![Page 13: Internal features of Heart Dr. Sama ul Haque. Objectives List the chambers of the heart. Describe the internal features of right atrium. Describe](https://reader036.vdocument.in/reader036/viewer/2022062515/56649c9e5503460f9495e020/html5/thumbnails/13.jpg)
• Aortic valve: has three semilunar valve cusps: right, left, and
posterior.
• Left atrioventricular valve (bicuspid valve or mitral valve):
has anterior & posterior cusps.
Left Ventricle

• Anterior papillary muscle and the posterior papillary muscle:
the chordae tendineae of each papillary muscle attach to both
valve cusps.
• Trabeculae carneae.
Left Ventricle

Fibrous Skeleton of the HeartDense collagenous fibrous tissue framework lies at the junction of the atria with the ventricles.Includes:1-Tricuspid fibrous annulus: 2-Mitral fibrous annulus3-Pulmonary fibrous annulus: 4-Aortic fibrous annulusFunctions:1-Supports the valves. 2-Electrically separetes atria from ventricles.
