The inner wing of the iliac bone
33 of 57
What is the name of the must superior muscle in the anterior compartment of the thigh?
Sartorius muscle
34 of 57
Where does sartorial originate and insert?
Originates from the iliac bone and travels diagonally cross the quadriceps to insert into the proximal end of the medial side of the tibia
35 of 57
What is the name of the main muscle in the quadricep group?
Quadriceps femoris (4 heads)
36 of 57
Where do the 4 heads of quads femurs originate?
3 from the shaft of the femur and 1 from the iliac bone
37 of 57
What is the name of the tendon where all 4 heads of quads femoris join ad where does it insert?
Quadriceps tendon, inserts into the patella (knee cap)
38 of 57
What connects the patella to the tibia?
The patella ligament
39 of 57
What is the name of the most superficial muscle in the quadriceps group (located below sartorius)?
Rectus femoris
40 of 57
Where does rectus femora originate?
Originates from the iliac bone and runs inferiorly
41 of 57
What group of muscles in the anterior compartment of the thigh originate from the shaft of the femur?
The vastus muscles (medialis, lateralis and intermedius)
42 of 57
Where is vastus intermedius located which means it is hard to see?
Under the cover of rectus femoris (deep)
43 of 57
What is another name for the medial compartment of the thigh?
The adductor group (they bring about adduction)
44 of 57
Where is the main origin for the adductor group?
The pubic bone of the pelvis (some fibres coming from the ischium)
45 of 57
Where is the main insertion point of the muscles of the adductor group of the thigh?
The linea aspera of the femur
46 of 57
What is the most superior muscle in the adductor group?
The pectineus (pubic bone to proximal femur)
47 of 57
What muscle lies just inferior to penctineus?
Adductor longus (long fibres which pass 2/3 of the way down the femur)
48 of 57
Where is gracilis muscle located (adductor group)?
Superficial strap muscle located medially, runs down length of femur (pubic bone to tibia)
49 of 57
Which 2 adductor muscles can you see when you remove pectinous and adductor longus?
Adductor brevis (short muscle pubis to proximal femur) and adductor magnus which is the largest adductor muscle (pubis to whole length of femur)
50 of 57
Where does adductor magnus insert into?
The length of the femur and the adductor tubercle
51 of 57
Where do the hamstring muscles originate from and insert?
Otiginate from the ischial tuberosity and insert into either the tibia to the fibula
52 of 57

Biceps femoris
53 of 57
Where do the 2 heads of biceps femoris originate and insert?
Originate from the ischium (long) and the shaft of the femur (short) and both insert into the head of the fibula
54 of 57
What are the names of the other 2 hamstring muscles?
Semimembrinosis and semitendinosis
55 of 57
Where are semi membrinosis and tendinitis located?
Medially on the posterior of the thigh
56 of 57
How can you tell the 2 'semi' muscles of the hamstring apart?
