Which group of muscles are contained in the posterior thigh?
hamstring mm.
What muscles make up the hamstrings?
semitendinosus
log head of biceps femoris
semimembranosus
Which tendons can be felt on the medial side of the knee?
semitendinosus
semimembranosus
Which tendon can be felt on the lateral side of the knee?
biceps femoris
Where do the muscles of the posterior thigh originate?
ischial tuberosity
Are the biceps femoris positioned laterally or medially?
laterally
Are the semimembranosus and semitendinosus positioned laterally or medially?
medially
Which joints do the hamstrings cross?
hip and knee joints
What do the hamstrings function to do?
extend thigh
flex knee
Where is the semimembranosus positioned?
in front of semitendinosus and behind adductor magnus
All muscles in the posterior thigh are supplied by what artery?
four perforating branches of profunda femoris artery
The inferior gluteal artery supplies several small branches to which muscles of the posterior thigh?
muscles attached to ischial tubrosity
What artery does the femoral artery continue as?
popliteal artery
When does the femoral artery become the popliteal artery?
as it enters the popliteal fossa
What is the function of all the muscles arising from the ischial tuberosity?
assist gluteus maximus in extending thigh
Which way do patients with paralyzed posterior hamstrings tend to fall?
forward
What would not allow free simultaneous flexion of the thigh and extension of the leg concerning semitendinosus, semimembranosus and long head of the biceps? (bending over with the knees straight to touch the floor)
The muscles are not long enough
Sharp flexion of the thigh produces flexion of:
the leg as a result of the resistance of the hamstrings
Extension of the leg produces extension of :
the thigh
What is the popliteal fossa?
space behind the knee with no muscle tendons crossing
What is the most injuried nerve in the body?
common peroneal n.
Where do you find the common peroneal n.?
right next to head of fibula
What are the consequences if the common peroneal n. is injuried?
