syndesmosis
know the bony lanmarks of the tibia and fibula
what type of joint is the knee
synovial, modified hinge joint
why is the knee considered a synovial, modified hinge joint
because it can do some medial and lateral rotation in addition to the flexion and extension
what are the movements possible at the knee joint
flexion/extension
some medial and lateral rotation
true or false: we have unlimited range for the medial and lateral rotation at the knee

knee extension and hip fliexion
be able to identify the quadriceps
w
what is embedded in the quad tendon
sesmoid bone the patella

to increase the level arm for the quadriceps
when going to the tibial tuberocity, is it considered quadripcep tendon or patellar lgiament

hip adduction, lateral rotation
what is the most medial muscle of the thigh
gracilis
what is the origin of the gracilis
pubis
what is the insertion of the gracilis
anteromedial tibia in pes anserinus
what is the action of the gracilis
adduction of the hip
flexion of the knee
medial rotation of the leg, esp when sitting
what are the deep adductors of the thigh
adductor brevis
adductor magnus
what is the origin of the adductor brevis
pubis
what is the isnertion of the adductor brevis

true or false: adductor brevis is deep to pectineus
true
true or false: the adductor magus has 3 parts and name
false 2
adductor part and hamstring part
what is the origin of the adductor magnus
pubis ans ischial tuberocity to
what is the insertion of the adductor magnus
linea aspera (A part)

sartorius, gracilis, semi tendinosus
name the 3 muscles part of pes anse. from atnerior to psoterior
sartorius, gracilis and semitendinoses
what are the 2 major nerves that supply the anterior and medial thigh
obturator and demoral
femoral n is derevied from what spinal n

femoral n supplies what muscles of the thigh
sartorius
quadriceps femoris

obturator n originates from what spinal n
l2-l4
where does the obturator n travel
trough obturator canal
true or false: femoral n supplies mostly the anterior compaortment
true
what muscles are innevated by obturator

sartorius (medial edge)
what is the medial border of the femoral triangle
adductor longus (lateral edge)
what is the floor border of the femoral triangle
pectineus and ilioppsoas
what are the contents of the femoral sheath

inguinal lymphnodes
true or false, the femoral n is contained in the femoral sheath
false, just outside (most lateral)
great saphenous vein drains into what
femoral bv
understand the femoral triangule
what is the femoral canal and what does it contain
potential space, normally contains lymph nodes and fat
narrower and tighter than the inguinal cana;
which is narrower and tighter, the femoral canal or inguinal canaal
femoral canal
which is the more more problematic hernia: femoral or inguinal and why
femoral because the canal is smaller and tighter so it may cause strangulation of bowel
what does a femoral hernia look like i nthe early stage
bulge in groin/upper thigh, may move in and out with activity
what happens to the femoral hernia when you lie
lump disspears
in the late stages of the femoral hernia what is happening and why is it dangrous
the intestines become cause in the femoral canal because it is narror and tight
=may cause strangulation of bowerl
what is the fix for late stage femoral hernia
surgical innevration
inguinal canal is site for what types of hernia
inguinal hernas
