femur and anterior thigh Flashcards
what are the regions of the lower limb?
Gluteal region
Thigh region
Knee region
Leg region
Ankle region
Foot region
what is the femur?
- longest & heaviest
- It consists of a shaft and two ends
- Proximal end consists of
Head
Neck
Two trochanters /Greater and lesser - Intertrochanteric line
- Intertrochanteric crest
What is the shaft of the femur?
- Posteriorly broad rough line =linea aspera
- Superiorly (2 lips)- Pectineal line and gluteal tuberosity
- Inferiorly (2 lips)- medial
supracondylar line and lateral
supraconylar line
what is the distal end of femur?
- Medial and lateral condyle
- Medial and lateral epicondyle
- Interconylar fossa
- Patellar surface
what is the hip joint?
head of femur and acetabulum of pelvic bones
what is the ligaments of hip joint?
- Iliofemoral - restricts hyperextension
- Pubofemoral- restricts hyperextension
- Ischiofemoral- restricts hyperabduction
where is the fascia lata, medial intermuscular septum, lateral intermuscular septum, and posterior intermuscular septum located in thigh organization?
- Fascia Lata
- Medial Intermuscular
Septum - Lateral Intermuscular
Septum - Posterior Intermuscular
Septum
what is the function and innervation of anterior compartment of thigh?
Function: Flex hip & extend knee
Innervation: Femoral Nerve
what is the function and innervation of medial compartment of thigh?
Function: Adduct hip
Innervation: Obturator Nerve
what is the function and innervation of posterior compartment of thigh?
Function: Extend hip & Flex
Knee
Innervation: Sciatic Nerve
what does anterior compartment muscles do?
- Primarily responsible for flexion of the hip and extension of the knee
- Innervated by: Femoral Nerve
locate the iliopsoas, pectineus, sartorius in femoral nerve in anterior compartment muscles of thigh
green is pectineus
purple is iliopsoas
pink is sartorius
locate the rectus femoris, vastus lateralis, vastus medialis, vastus intermedius in quadriceps femoris in anterior compartment muscles of thigh
red is rectus femoris
teal is vastus lateralis
purple is vastus medialis
green is vastus intermedius (located inside of rectus femoris)
what is the origin, action, insertion, and innervation of iliopsoas
origin- Psoas: T12-L5
Iliacus: Ilium
action - flexion of hip
insertion - lesser trochanter
innervation - Femoral Nerve, Anterior Rami L1-L3
what is the origin, action, insertion, and innervation of pectineus
origin - Pubic superior ramus
action - Adduction of hip, Flexion of hip
insertion - Proximal femur
innervation - Femoral Nerve
