Anatomy Flashcards
Contents of femoral sheath
Femoral artery (lateral compartment)
Femoral vein (intermediate compartment)
Lymphatics
Femoral branch of genitofemoral nerve (L1)
Contents of femoral canal
Fatty connective tissue
Lymph vessels from deep inguinal nodes
Deep inguinal node of Cloquet (drains the clitoris and penis)
Femoral ring boundaries
Ant: inguinal ligament
Post: superior ramus of pubis, pectineal ligament
Med: lacunar lig, iliopubic tract
Lat: fem vein
These are also the margins of a femoral hernia neck, therefore likely to strangulated as 3/4 boundary walls are rigid
What passes through the diaphragm.
- T8 - what passes through this and where?
- T10 - what and where?
- T12 - what and where?
- Central tendon of diaphragm: IVC and R. phrenic, therefore right side of central tendon
- Right crus: (LOV 10) - Left gastric artery and vein branches; Oesophagus; Vagi
- Behind diaphragm (T12, median arcuate ligament) - aorta; (hemi)azygos; thoracic duct (TAA)
Indentations of the right lung
RS: trachea
CVS: heart (RA); brachiocephalic vein; aorta; IVC..; azygos
GIT: oesophagus
Indentations of left lung
Aorta
cardiac impression
oesophagus
subclavian artery
Recurrent laryngeal nerve:
- Where does right and left nerves loop around?
- What does it innervate?
- R: R. subclavian a.
L: Ligamentous arteriosus, runs between oesophagus and trachea - Motor: all muscles of larynx, except cricothyroid
Sensory: larynx
Mucosa innervation: upper trachea and oesophagus
Oesophagus:
- Origin
- End
- Arterial supply
- Venous supply
- Innervation
- Level of lower cricoid cartilage. Left in neck.
- Right crus of diaphragm (T10, with L. gastric vessels and vagi). Returns to midline at T5.
- Inf. thyroid artery; aortic branches; L. gastric a.
- Inf. thyroid vein; azygos; L. gastric v
- Sensory innervation from recurrent laryngeal nerve.
Phrenic nerve:
- Origin, course in neck
- Motor supplies
- Sensory supplies
- C3-5, with sympathetic from C1-6(?) grey rami
- diaphragm
- Diaphragmatic peritoneum, mediastinal pleura, parietal pericardium
Indications for CABG
- Triple vessel disease
- > 50% stenosis of left main stem
- UA post-MI
- Pts for valvular surgery with concomitant coronary vessel disease
Anything else can usually PCI (ie. single or double vessel disease)
Diathermy plate electrode:
- Where should it be placed
- Minimum area that should be covered
- Either limb or trunk
2. 70cm^2
Where to find the costodiaphragmatic recess at:
- Mid-clavicular line
- Mid-axillary line
- Paravertebral
- ribs 6-8
- ribs 8-10
- ribs 10-12
What is the “cupola”?
Cervical parietal pleura, which goes slightly above the 1st rib and into the neck
Transpyloric plane
1. Which vertebral level
- What lies at the plane
- L1 (inferior border), 9th costal cartilage tip
- GIT: pylorus; duodenojenunal flexure
Pancreas neck
Kidney hila
