Pelvis and Thigh Kinesiology Flash Cards
Directions The first slide asks a question. The second slide answers the question. Use these slides like flash cards to test your core knowledge.
Question How many bones are in the thigh?
Answer There is only one bone in the thigh.
It is the femur.
Question What action at the knee does the quadriceps muscle group have?
Answer The quads action at the tibiofemoral (knee) joint is extension of the leg.
Question Place these items in order from superior to inferior: PatellaQuadriceps femorisPatellar ligamentTibial tuberosityQuadriceps tendon
Answer In order from superior to inferior they are:Quadriceps femorisQuadriceps tendonPatellaPatellar ligamentTibial tuberosity
Question What is the longest muscle in the human body?
Answer The sartorius muscle, with its length spanning from the ASIS to the pes anserine.
Question What muscle is nicknamed the tailor muscle?
The nickname comes from the position that tailors stand in when working at their tall tables, which is caused by the action of the sartorius. (Slight hip flexion, slight hip abduction, hip lateral rotation, and slight knee flexion.) Stand firmly on the left leg. Laterally rotate the right leg, cross the right foot over the left, and touch the toes of the right foot to the ground, just lateral to the left foot. This comfy position is the tailor position.
Question Which one of the four quadriceps muscles crosses the hip joint?
Answer Of the quads, only the rectus femoris crosses the hip joint. All of the quads cross the knee joint.
Question What muscle group is the antagonist of the quadriceps?
Answer The hamstrings, the posterior thigh muscles, are the antagonists of the quadriceps.
Question Name the muscles of the hamstrings.
Biceps femoris (long head and short head)
Question What are the medial hamstrings?
Question What are the lateral hamstrings?
Question In general, the hamstring muscle group originates from the ischium. There is one head of the hamstring that does not originate at the ischium, but rather from the posterior femur. What is that muscle?
Answer The short head of the biceps femoris.The long head indeed does attach at the ischial tuberosity with the other hamstrings.
Question What muscles tendons make up the pes anserine?
Mnemonic Device: Slippery Green Snakes
Question Where will you find the pes anserine?
Answer At the medial, proximal portion of the tibia, just distal to the knee joint.
Question What muscle, whose name means graceful, is the most medial muscle of the thigh?
Answer The gracilis
Question What muscle is the prime mover of flexion of the hip?
Answer The iliopsoas
Question What two muscles combine to make the iliopsoas?
Answer The iliacus and the psoas major.
Question What part of the iliopsoas attaches at the anterior portion of the 12th thoracic vertebra and all lumbar vertebra?
Answer The psoas major origin
Question What part of the iliopsoas attaches to the iliac fossa?
Answer The origin of the iliacus muscle
Question What is the insertion of the iliopsoas?
Answer The lesser trochanter of the femur
Question What is the only bone to have trochanters?
Answer The femur
Question Which muscle of the quadriceps muscle group is synergistic with the iliopsoas?
Answer The proximal part of the rectus femoris also has flexion of the hip as an action, making the iliopsoas and the rectus femoris synergists.
Question Where are the deep six lateral rotators located?
Answer The deep six lateral rotators are found deep to the gluteus maximus.
Question What is the action of the deep six lateral rotators?
Answer They laterally rotate the thigh at the hip.
Question Name the deep six lateral rotators, from superior to inferior.
Answer PiriformisGemellus superiorObturator internusGemellus inferiorObturator externusQuadratus femoris
Question What attachment point do the deep six lateral rotators fan out from?
Answer The greater trochanter
Question What is the only muscle to truly cross the sacroiliac joint?
Answer The piriformis
Question What muscle can entrap the sciatic nerve, causing pseudo sciatica?
Answer The piriformis muscle
Question What is the origin of the piriformis muscle?
Answer The anterior sacrum
Question What is the origin of the rectus femoris?
Answer The anterior inferior iliac spine (AIIS)Note: It is the anterior inferior iliac spine, AIIS.
Question What is the insertion of the biceps femoris?
Answer The head of the fibula
Question Where will you find the iliotibial band?
Answer On the lateral thigh, superficial to the vastus lateralis muscle.
Question What two muscles blend into the iliotibial (IT) band at its superior portion?
Answer Anteriorly, the tensor fascia lata blends with the IT band.
The gluteus maximus blends with the IT band from the posterior.
Question What is the superior attachment of the IT band?
Answer The superior attachment for the IT band is the iliac crest.
Question What is the inferior attachment of the IT band?
Answer The inferior attachment of the IT band is the lateral proximal tibial shaft, at a point known as Gerdys tubercle.
Question What two joints does the IT band cross?
Answer The hip and the knee.
