|
||||
| show | from the crista terminalis
🗑
|
||||
| where is the tricuspid valve? | show 🗑
|
||||
| what is the composition of the RV? | show 🗑
|
||||
| show | it has a membranous part (inovled in defect) and a muscular part
🗑
|
||||

|
||||
| show | the septomarginal trebeculum carrying the R branch of the AV bundle to the anterior papillary muscle
🗑
|

|
||||
| show | the moderator band
🗑
|
||||
| What is the composition of the interior of the LA? | show 🗑
|
||||
| show | because it doesn't always have 2 cusps (bicuspid) however it normally does
🗑
|

| show | the LV has trebeculae carnae but they are much finer but more numerous
🗑
|
||||
| explain the main differences between the RV and LV? | show 🗑
|
||||
| show | the AV valves have chordae tendinae and papillary muscle associated, and semilunar valves don't
🗑
|
