TOPIC 26 Flashcards
1
Q
Dissection, what to do first?
A
- Divide thorax into sections, both on left and right side
- Talk about the lungs (lobes)
- Talk about the pericardium
- Talk about the topography of the thorax
Spaces (resesses/cupula)
●Precardiac
●Cardiac
●Postcardiac
2
Q
Dissection of mediastinum
A
Lift the phrenic nerve, make a small incision
= You will be inside/between heart&Mediastinum
Ligament attached to pericardium:
- Lig.phrenicopericardium
3
Q
The heart topography
A
Layers:
- Endocardium
- Myocardium
- Epicardium
- Pericardium has 2 layers:
Pericardium fibrosum - Thougher outer layer
Pericardium serosum - The inner layer - The parietal lamina is adherred to the pericardium fibrosum, while the viceral lamina is adherred to the heart - Also called epicardium
- Between those to laminas = Pericardial Fluid
4
Q
Topography of thorax - Spaces
A
- Cupula pleura
- Recessus costomediastinales
- Recessus costodiaphragmaticus
- Recessus lumbodiaphrahmaticus
- Recessus mediastini
- Recessus mediastinodiaphragmatica sinister
- Cavum mediastini serosum
5
Q
Lungs
A
Loceted in the plaural sac, which comes together medially to form the mediastinum
Left cranial lobe - pars Cran/caud Left Caudal Right cranial Medial lobe Right caudal Accessory lobe
6
Q
Pre-cardiac region
A
Tr. vagus symp Vagus nerve Tr.sympatheticus Ansa subclavia Ggl Stellate Mediastinum Phrenic nerve
Dont need to dissect vessels! A.subclavian A.carotis communis sinistra et dextra A.brachiocephalicus A.sublavia sinistra A.vertebralis A.rr costocervical branches A.thoracica interna A.intercostales ventrales A.pericardiophrenica
7
Q
Cardiac region
A
Recurrent laryngeal nerve Aortic arch Tr.symp Tr.vagus A.brachiocephalica A.subclavia A.bronchoesophagea A.perforates A.intercostalis ventralis A.rr.mammi
8
Q
Post-Cardiac region
A
Tr.sympatheticus Vagus nerve + Division Phrenic nerve Aa.tjoracica A.thoracica interna A.a innami?
