Q

what is the insertion of the quadriceps femoris muscles and how do all the muscles insert

A

converge onto quadriceps tendon

Q

actions of sartorius and what is important about its actions

hint: open the gate

A

flexes and laterally rotates the hip joint
flex the knee
not a prime mover- only contributes to these movements

23
Q

insertion and attachment of iliopsoas

A

psoas major and iliacus converge via a common tendon and insert onto the lesser trochanter of the femur

24
Q

what forms a superficial triangle in the anterior thigh

A

tensor fascia latae and sartorius

25
Q

where does pectineous lie

A

in proximal anterior thigh

medial to iliopsoas

26
Q

what is the origin and insertion of pectineus

A

origin= superior pubic ramus

insertion inferior to lesser trochanter on femur

27
Q

what innervates the medial thigh muscles and spinal roots of this

A

obturator nerve L2-L4

28
Q

what r the 5 muscles of the medial compartment

A
adductor brevis
adductor longus
adductor magnus
gracilis
obturator externus
29
Q

what is the general action of medial compartment of thigh muscles

A

adductors of hip

30
Q

why r the MIDDLE compartment muscles important for normal gait

A

help draw the leg back towards to the midline during walking

31
Q

what is the origin and insertion of the adductor brevis and longus

A
origin= pubic bone
attachment= linea aspera
32
Q

what is the location of adductor brevis in relation to adductor longus

A

adductor brevis lies deep to longus

33
Q

where is the obturator nerve found

A

between adductor brevis and longus

34
Q

what r the two parts of the adductor magnus called

A

adductor part and hamstring part

35
Q

what is the origin and insertion and innervation of the adductor part of the adductor magnus

A

origin= inferior pubic ramus
insertion= linea aspera
obturator nerve

36
Q

what is the adductor hiatus

A

gap betwen the distal attachments of the two parts of adductor magnus

37
Q

what travels through the adductor hiatus

A

femoral artery and vein

38
Q

attachment, insertion and actions of gracilis. is it a prime mover?- acronym is DUFF

A

pubic bone
medial aspect of tibia
weak adductor and flexor of hip, weak flexor of knee
not a prime mover

39
Q

attachment, insertion and function of obturator externus

A

external surface of obturator membrane
inserts onto femur near greater trochanter
stabilises and laterally rotates hip joint

40
Q

what is the femoral artery a continuation of

A

external iliac artery

41
Q

what is the branch that comes of the femoral artery called and where does it go and what does it innervate

A

profunda femoris
travels deep into thigh
supplies thigh

42
Q

how does femoral artery enter anterior thigh

A

travels deep to inguinal ligament

enters anterior thigh proximally

43
Q

what is the path of the femoral artery after the profunda femoris branches off and what happens to it?

A

continues distally to traverse the adductor hiatus
enters the distal part of posterior thigh called the popliteal fossa
here it becomes the popliteal artery

44
Q

what is the obturator artery a branch of

A

internal iliac artery

45
Q

what is the path of the obturator artery

A

travels through obturator canal into medial compartment of thigh
anastomoses with branches from femoral artery

46
Q

what is the path of the obturator vein

A

travels through obturator canal and joins internal iliac vein in the pelvis

47
Q

what is the path of the femoral vein

A

travels under inguinal ligament and is continuous with external iliac vein

48
Q

what is the position of the femoral vein in relation to the femoral artery

A

vein is medial to artery

49
Q

what is the path of the femoral nerve

A

travels deep to inguinal ligament

enters proximal anterior thigh lateral to femoral artery

50
Q

what is the innervation of the femoral nerve and its main branch’s innervation

A

femoral: anterior thigh muscles

saphenous nerve: sensory branch that innervates skin over the leg

51
Q

what is the path of the obturator nerve

A

travels along the lateral wall of the pelvis and exits through the obturator canal
emerges onto superficial surface of adductor brevis

52
Q

what is the innervation of obturator nerve

A

innervates the medial compartment muscles and skin over medial thigh

53
Q

what r the 3 borders of the femoral triangle

A

lateral: medial border of sartorius
medial: lateral border of adductor longus
superior: inguinal ligament

54
Q

what is the apex and floor of the femoral triangle

A

apex: where sartorius and adductor longus meet
floor: made up of iliopsoas laterally and pectineus medially

55
Q

what r the 4 important contents of the femoral triangle

A

femoral artery
femoral vein
great saphenous vein (joins femoral vein)
femoral nerve
