Q

quads

A

powerful knee extensors, come together to form the quadriceps tendon which attaches superiorly to patella femoral n. 1. rectus femoris: 2 heads, AIIS, ant capsule of hip joint, also flexes hip ONLY ONE THAT CROSSES HIP JOINT 2. vastus lateralis 3. vastus medialis 4. vastus intermedius

Q

anterior thigh muscles (5)

A

sartorious

TFL

quads

pectineus

iliopsoas

17
Q

medial comp thigh muscles (5)

A

pectineus

adductor longus

adductor brevis

adductor magnus

gracilis

flex and adduct hip, assist in internal rot obturator nerve

18
Q

adductor magnus

A

can also extend hip

dual innervation–> 2 portions

  1. anterior/adductor portion: obturator n
  2. post/hamstring portion: extends hip, sciatic n
19
Q

gracilis

A

2 joint muscle

most medial medial comp muscle

flexes & adducts hip

flexes knee

inwardly rot tibia on femur with knee flexed

20
Q

femoral cut n

A

lateral thigh

21
Q

femoral n

A

cut: skin on ant and med thigh
motor: quads, sartorius, half of the pectineus

22
Q

muscles in post comp

A

hamstrings

23
Q

hamstrings

A

biceps femoris: long head inserts on ischial tub, short on linea aspera, both connect to the head of the fib semimembranosus

semitendonosus

sciatic n

24
Q

pes anserinus

A

sartorius

gracilis

semitendonosus

all insert onto the ant med tib and flex the knee

also inwardly rot when knee is flexed

25
ant comp innerv
femoral, lat femoral cut
26
med comp innerv
obturator
27
post comp innerv
**sciatic**: lateral/common fib: short head of biceps femoris only tibial portion: all other hamstrings post femoral cut: to skin in post comp
28
blood supply to ant comp
sup femoral A. ---\> deep femoral
29
blood supply to med comp
obturator A ---\>med and lat femoral Cx
30
blood supply to post comp
deep femoral A
31
osgood schlatus
tibial tuberosity doesnt fuse till late, gets pulled away from tibia, bone grows faster than muscle
32
popliteal artery
found in popliteal fossa, supplies knee joint and its capsule
33
innervation of quads
femoral
34
innervation of TFL
superior gluteal
35
innervation of sartorius
femoral
36
innervation of pectineus
DUAL: femoral and obturator
37
innervation of iliopsoas
L1&L2 ventral rami
38
adductor magnus innervation
DUAL: anterior portion: obturator post portion: sciatic
