-
What bones make up the pelvis?
-
Name the bone/parts of the hip bone.
-
What is another name for the hip joint?
Coxal joint-
-
What is the scientific name for the knee joint?
Tibiofemoral joint
-
Based on the movements it permits, what type of joint is the tibiofemoral joint?
Modified hinge joint because it permits some rotation when the knee is flexed.
-
Name the muscles that make up the Quadriceps Femoris muscle group.
- Rectus Femoris-
- Vastus Lateralis-
- Vastus Intermedius-
- Vastus Medialis-
-
What characteristics do all four quadriceps muscles share?
- 1. They all share an insertion at the tibial tuberosity.
- 2. They all participate in knee extension.
-
Which quadriceps muscle crosses two joints?
Rectus Femoris
-
greater trochanter of the femur:
- A large, irregular quadrilateral eminence, just inferior and lateral of the head and neck of the femur.
- Its borders provide attachment sites for muscles of the hip and thigh (i.e., piriformis, vastus lateralis, and gluteus minimus).
-
gluteal tuberosity of the femur:
- The lateral one of three upward prolongations of the linea aspera of the femur, extending to the base of the greater trochanter.
- The principal insertion site for the gluteus maximus muscle.
-
linea aspera:
- A prominent longitudinal ridge or crest, on the middle third of the posterior femur.
- It presents a medial and a lateral lip, and a narrow rough, intermediate line.
- It is an important insertion point for the adductors, and the inter muscular septa.
-
anterior inferior iliac spine:
- A bony eminence on the anterior border of the ilium just inferior to the anterior superior iliac spine.
- The upper portion of the spine gives origin to the straight head of the rectus femoris muscle.
-
tibial tuberosity:
- An elevation on the proximal, anterior surface of the tibia, just below the anterior surfaces of the lateral and medial condyles.
- Attachment site for the patellar ligament
-
List the quadriceps muscles.
- Rectus Femoris-
- Vastus Lateralis-
- Vastus Medialis-
- Vastus Intermedius-
-
What are the origin and insertion for the Rectus Femoris muscle?
- Origin-Anterior inferior iliac spine (AIIS)
- Insertion-Tibial tuberosity via the quadriceps tendon, patella and patella ligament.
-
What actions does the Rectus Femoris muscle enable?
- Extension of the leg at the knee joint
- Flexion of the thigh at the hip joint
-
What are the origin and insertion for the Vastus Lateralis muscle?
- Origin-Greater trochanter, gluteal tuberosity, lateral lip of the linea aspera
- Insertion-Tibial tuberosity via the quadriceps tendon, patella and patella ligament
-
What actions does the Vastus Lateralis muscle enable?
Extension of the leg at the knee
-
What are the origin and insertion for the Vastus Medialis muscle?
- Origin-Medial lip of linea aspera
- Insertion-Tibial tuberosity via quadriceps tendon, patella, and patella ligament
-
What actions does the Vastus Medialis muscle enable?
Extension of the leg at the knee
-
What are the origin and insertion for the Vastus Intermedius muscle?
- Origin-Anterior and lateral shaft of femur
- Insertion-Tibial tuberosity via quadriceps tendon, patella, and patella ligament
-
What actions does the Vastus Intermedius muscle enable?
Extension of the leg at the knee joint
