1. Right ventricle: It is the most anterior chamber of the heart, that continues the right atrium. It has a triangular shape, and consists of 3 components: An inlet, a trabecular part and an outlet. (3)
2. AR Figure 93 – Right ventricle: Overview
   1. Inlet of right ventricle
      1. Inlet of right ventricle: It is the part of the ventricle that contains the tricuspid valve with its chordae and papillary muscles. (3)
   2. Supraventricular crest
      1. Supraventricular crest: It is a prominence that is situated between the pulmonary valve and the tricuspid valve. (3)
   3. Conus arteriosus
      1. Conus arteriosus: It is the outlet component of the right ventricle and is a conical pouch situated in the right ventricle's upper part. It provides support for the pulmonary valve. (1,3)
   4. Trabecular part of right ventricle
      1. Trabecular part of right ventricle: It is thin and reaches the apex of the heart. It contains coarse trabeculations. (3)
3. Trabecular part of right ventricle
   1. Papillary muscles of right ventricle
      1. AR Figure 93 – Right ventricle: Overview,
         1. Papillary muscles of right ventricle: They are protrusions projecting into the ventricle lumen that attach to the tricuspid valve cusps via chordae tendineae. They are 3 in number: the right ventricle's anterior, inferior, and septal papillary muscles. (1,2)
         2. Anterior papillary muscle of right ventricle
            1. Anterior papillary muscle of right ventricle: It is the largest papilary muscle of the tricuspid valve. The septomarginal trabecula provides support to this muscle. (4)
         3. Inferior papillary muscle of right ventricle
            1. Inferior papillary muscle of right ventricle: Arising from bellow, it is the second largest papillary muscle of the tricuspid valve. (4)
         4. Septal papillary muscle of right ventricle
            1. Septal papillary muscle of right ventricle: The smallest papillary muscle of the tricuspid valve, it arises from the parietal limb of the septomarginal trabecula. (4)
         5. Chordae tendineae of right atrioventricular valve
            1. Chordae tendineae of right atrioventricular valve: Fibrous string cords that connect the valve leaflets to the papillary muscles. In the right ventricle the septal leaflet of the tricuspid valve is anchored directly to the septum. (1,3)
         6. Chordae tendineae spuriae of right ventricle
            1. Chordae tendineae spuriae of right ventricle: also known as false chordae are more commonly observed in the left ventricle, are fibrous-muscular bundles found in the ventricles of the heart, distinct from "true" chordae as they do not interconnect with atrioventricular valves. (1,5)
   2. Trabeculae carneae of right ventricle
      1. AR Figure 94 – Right ventricle: Trabecular part
         1. Trabeculae carneae of right ventricle: Irregular muscular elevations found on the inner aspect of the inflow tract path in the right ventricle. (1,2,3)
         2. Septomarginal trabecula
            1. Septomarginal trabecula: The Septomarginal Trabecula, also referred to as the septal band, is a significant and distinctive feature in the septal area of the right ventricle. It possesses two parts: an anterosuperior limb and a posteroinferior limb that secures the septal region of the supraventricular crest. Various prominent trabeculations often emanate from it, including those that create the anterior papillary muscle and the moderator band. (1,5)
         3. Coarse apical trabeculations
            1. Coarse apical trabeculations:They are tough muscle bundles located at the apex of the right ventricle. They're a special feature of the right ventricle's inner shape contrasting with the finer trabeculations seen in the apical part of the left ventricle. (5,6)
