Stegno Flashcards
1
Q
Stegno - splošno
A
3 kompartmenti, vsak ima svojo inervacijo
- anteriorni - n. obturatorius
- posteriorni - n. ischiadicus
- medialni - n. femoralis
2
Q
Stegno - posteriorni kompartment - splošno
A
fleksorji kolena
ekstenzorji stegna
hamstringi!!
veje a. femoris profundae + veje inferiorne glutealne arterije
n. ischiadicus
3
Q
Stegno - posteriorni kompartment - mišice
A
- Biceps femoris - 2 glavi:
- dolga - tuber ishi -> glava fibule
- kratka - lateralni del linea aspere femurja -> glava fibule
- Semitendinosus - inferomedialni del tuber ishi -> medialna površina tibije
- Semimembranosus - superlateralni del tuber ishi -> posteriona površina medialega tibialnega kondila
4
Q
Biceps femoris
A
- najbolj lateralno!!!
- Origin
- Long head: inferomedial part of the ischial tuberosity
- Short head: lateral lip of the linea aspera
- Insertion
- Head of the fibula
- Action:
- Knee flexion
- Hip extension
- Lateral rotation at the hip and knee joint
- Innervation
- Long head: tibial division of the sciatic nerve
- Short head: common fibular division of the sciatic nerve
- Blood supply
- Inferior gluteal artery supplies the superior portion of the muscle
- Perforating arteries of profunda femoris supply the majority of the muscle
5
Q
Semitendinosus
A
- medialno glede na biceps!! enaki origo kot dolga glava bicepsa!!
- Origin
- Inferomedial part of the ischial tuberosity
- Insertion
- Medial surface of the tibia
- Action
- Knee flexion
- Hip extension
- Medial rotation of the thigh at the hip joint
- Medial rotation of the lower leg at the knee
- Innervation
- Tibial division of the sciatic nerve
- Blood supply
- Inferior gluteal artery supplies the superior portion of the muscle
- Perforating arteries of profunda femoris supply the majority of the muscle
6
Q
Semimembranosus
A
- bolj superiorni origo!!! najbolj medialno!!
- Origin
- Superolateral part of the ischial tuberosity
- Insertion
- Posterior surface of the medial tibial condyle
- Action
- Knee flexion
- Hip extension
- Medially rotation of the thigh at the hip joint
- Medial rotation of the lower leg at the knee joint
- Innervation
- Tibial division of the sciatic nerve
- Blood supply
- Inferior gluteal artery supplies the superior portion of the muscle
- Perforating arteries of profunda femoris supply the majority of the muscle
- Inferior gluteal artery supplies the superior portion of the muscle
7
Q
Clinical relevance - hamstringi
A
šport
sudden change in speed and direction
najpogosteje mišično tetivni spoj
adolescenti -> avulzijska fraktura ishialnega tuberkla!!
8
Q
Stegno - anteriorni kompartment - splošno
A
ekstenzorji kolena
fleksorji stegna
3 mišice
9
Q
Stegno - anteriorni kompartment - mišice
A
- articularis genu - mini mišica OwO… won’t learn…
- sartorius - anterior superior spina iliaka (ASIS eng) -> medialni del tibije, inferiorno glede na tuberositas tibije
- kvadriceps femoris
- rectus femoris - ASIS -> skupna tetiva kvadricepsa na patelo
- vastus medialis - femur -> skupna tetiva kvadricepsa na patelo
- vastus intermedius - antero/lateralni femur -> skupna tetiva kvadricepsa na patelo
- vastus lateralis - velik trohanter femurja -> skupna tetiva kvadricepsa na patelo
10
Q
Sartorius
A
- najbolj povrhen!!!
- medialni del mišice je lateralna stena femoralnega trigonuma
- origo dejansko superiorno glede na ASIS
- Origin
- Originates on the anterior superior iliac spine (ASIS) on the pelvis
- Insertion
- Inserts onto the medial aspect of the tibia, just inferior to the tibial tuberosity
- Innervation
- Femoral nerve (L2, L3)
- Action
- Flexion of the hip
- Flexion of the knee
- Abduction of the thigh
- Lateral rotation of the thigh
11
Q
Rectus femoris
A
- Origin
- Rectus femoris has two heads of origin, one from the anterior superior iliac spine (straight head) and the other from the ilium immediately superior to the acetabulum (reflected head)
- The two heads converge to form a common muscle
- Insertion
- The rectus femoris tendon converges with the quadriceps femoris tendon to form the patellar tendon
- The patellar tendon inserts onto the base of the patella
- Innervation
- Femoral nerve (L2, L3, L4)
- Action
- Flexion of the hip
- Extension of the knee
12
Q
Vastus medialis
A
- najbolj medialno!!
- Origin
- The vastus medialis has a long origin along the femur.
- It starts on the intertrochanteric line, descends posteroinferiorly along the pectinate line and along the linea aspera, down to the medial supracondylar line.
- Insertion
- It inserts onto the medial aspect of the quadriceps tendon and the medial border of the patella.
- Innervation
- Femoral nerve (L2, L3, L4)
- Action
- Extension of the knee
13
Q
Vastus intermedius
A
- behind rectus in med medialnim in lateralnim vastusom
- Origin
- The muscle originates from the upper two-thirds of the anterolateral surface of the femur.
- Insertion
- Vastus intermedius inserts onto the quadriceps femoris tendon, as well as the lateral border of the patella and the lateral condyle of the tibia.
- Innervation
- Femoral nerve (L2, L3, L4)
- Action
- Extension of the knee
14
Q
Vastus lateralis
A
- največja med vsemi!!!
- Origin
- The muscle originates along the femur, starting from the superior intertrochanteric line, before moving laterally to the lateral gluteal tuberosity and down the lateral aspect of the linea aspera.
- Insertion
- Vastus lateralis inserts onto the quadriceps femoris tendon and the lateral aspect of the patella.
- Innervation
- Femoral nerve (L2, L3, L4)
- Action
- Extension of the knee
