ANATOMY
60
a. Posterior cruciate is weaker than the ACL
c.
Best approach for aspiration knee joint is from medial side.
Septic arthritis may be caused by pre-patellar bursitis
Gastrocnemius bursa communicates with knee joint
Haemathrosis can occur from a torn cruciate ligament rupturing the middle genicular artery
What is incorrect?
a. IM injection at the superolateral quadrant of the buttock is best to avoid the sciatic nerve.
b. Supplied by both superior and inferior gluteal nerve (we put this one)
c. Supplied by both superior and inferior gluteal arteries
d. strong anti-gravity muscle
Medial muscles of the thigh
a.
supplied by obturator artery
b.
myotomes for all muscles in this compartment was L4-L5
c.
cause mainly flexion of hip
d.
medial intermuscular septum attaches to fascia lata
Adductor canal
a. Femoral artery (or vein?) always lies btw the saphenous nerve and the femoral vein (? artery)
b. Femoral vein lies medial to the femoral artery at the adductor hiatus
c. Roof partly formed by gracilis
d. Adductor longus (Something I thought was wrong)
Trachea
a.
is a fibrocartilaginous tube
b.
1.5 cm diameter
c.
goes from epiglottis to R) and L) bronchi
Relations
a.
R) vagus goes behind root of R) lung
b.
L) vagus goes behind root of L) lung
c.
L) phrenic crosses posterior to arch of aorta
d.
L) recurrent laryngeal nerve runs in the groove btw trachea and esophagus
Lymphatics of the arm
a.
superficial run with arteries
b.
deep run with veins
c.
don’t run with the vessels at all
d.
drainage from thumb goes to lateral humeral LN
e.
(something that we thought was wrong)
Lumbar plexus (learn!)
Regarding the ventricular system
the lateral ventricle drains via the interventricular foramen to the 4
th
ventricle
the inferior horns are larger than the posterior horns
the inferior horns lie in the temporal lobe
the lateral ventricle does not have choroidal cells
CSF
1000mL is made daily
venous pressure has no effect on CSF pressure
Kiesselbach (nose) plexus – learn what forms it
formed by branches of ICA and ECA
formed by branches of maxillary and mandibular arteries
formed by branches of mandibular and ophthalmic arteries
inf and sup ethmoid supply the plexus
