 Quadriceps Femoris Groups is made up of which muscles | rectus femoris, vastus medialis, vastus lateralis, vastus intermedius |
| Action of the all the quadriceps muscles | extend the knee |
| Rectus Femoris: Action | Flex the hip |
| Rectus Femoris: Origin | anterior inferior iliac spine (AIIS) |
| Rectus Femoris: Insertion | tibial tuberosity (via the patella and patellar ligament) |
| Rectus Femoris: Nerve Innervation | Femoral |
| Vastus Medialis: Origin | Medial lip of the linea aspera |
| Vastus Medialis: Insertion | tibial tuberosity (via the patella and patellar ligament) |
| Vastus Medialis: Nerve Innervation | Femoral |
| Vastus Lateralis:Origin | lateral line of the linea aspera, gluteal tuberosity, and greater trochanter |
| Vastus Lateralis: Insertion | tibial tuberosity (via the patella and patellar ligament) |
| Vastus Lateralis: Nerve Innervation | Femoral |
| Vastus Intermedius: Origin | anterior and lateral shaft of the femur |
| Vastus Intermedius: Insertion | tibial tuberosity (via the patella and patellar ligament) |
| Vastus Intermedius: Nerve Innervation | Femoral |
| The vastus medius and vastus lateralis work together to do what? | stabilize the tibiofemoral joint |
| The contraction of the quadriceps does what leading to knee extension | contraction of the quadriceps pulls the patella upwards and leads to knee extension |
| Exercise for the quads | squat, leg press, and knee extension |
| Stretch for the quads | lean back on bent knees |
| Name the muscles that make up the hamstrings | Biceps Femoris, Semitendinosus, Semimembranosus |
| Biceps Femoris: Action | flex the knee, laterally rotate the flexed knee, tilt the pelvis posteriorly long head: extend the hip and assist to laterally rotate the hip |
| Biceps Femoris: Origin | Long Head: Ischial Tubersoisty Short Head: Lateral lip of the linea aspera |
| Biceps Femoris: Insertion | head of the fibula |
| Biceps Femoris: Nerve Innervation | Long Head: Sciatic (tibial branch) Shorty Head: Sciatic (peroneal branch) |
| Semitendinosus: Action | flex the knee, medially rotate the flexed knee, extend the hip, assist to medially rotate the hip, tilt the pelvis posteriorly |
| Semitendinosus:Origin | ischial tuberosity |
| Semitendinosus:Insertion | proximal, medial shaft of the tibia at pes anserinus tendon |
| Semitendinosus:Nerve Innervation | sciatic (tibial branch) |
| The semitendinosus is ______ to the semimembranosus | superficial |
| Semimembranosus: Action | flex the knee, medially rotate the flexed knee, extend the hip, assist to medially rotate the hip, and tilt pelvis posteriorly |
| Semimembranosus:Origin | ischial tuberosity |
| Semimembranosus:Insertion | posterior aspect of medial condyle of tibia |
| Semimembranosus:Nerve Innervation | sciatic (tibial branch) |
| Name the muscles that make up the gluteals | Gluteus Maximus, Medius, Minimus |
| Gluteus Maximus: Action | all fibers: extend the hip, laterally rotate the hip, and abduct the hip lower fibers: adduct the hip |
| Gluteus Maximus: Origin | coccyx, edge of sacrum, posterior iliac crest, sacrotuberous and sacroiliac ligaments |
| Gluteus Maximus: Insertion | iliotibial tract (upper fibers) and gluteal tuberosity (lower fibers) |
| Gluteus Maximus: Nerve Innervation | inferior gluteal |
| Gluteus Maximus Stretch | contralateral pull of knee to chest |
| Gluteus Maximus Exercise | hip action without full extension with knee flexed at greater or equal to 30 degrees flexion (elliptical) (upward motion of a squat, jumping) |
| Explain why the upper fibers assist in abduction and the lower fibers assist in adduction | the head of the femur is located between the upper and lower fibers therefore splitting the action |
| Gluteus Medius: Action | ALL fibers: abduct the hip ANTERIOR: flex the hip, medially rotate hip POSTERIOR: extend the hip and laterally rotate the hip |
| Gluteus Medius: Origin | gluteal surface of the ilium, between posterior and anterior gluteal lines, just below the iliac crest |
| Gluteus Medius: Insertion | lateral aspect of greater trochanter |
| Gluteus Medius: Nerve Innervation | superior gluteal |
| Gluteus Medius Exercise | hip external rotation against resistance/ gravity (Jane Fonda) |
| Gluteus Medius Stretch | extreme adduction in front of opposite extremity |
| Gluteus Minimus: Action | abduct the hip , medially rotate the hip, flex the hip |
| Gluteus Minimus: Origin | gluteal surface of the ilium between the anterior and inferior gluteal lines |
| Gluteus Minimus: Insertion | anterior aspect of the greater trochanter |
| Gluteus Minimus: Nerve Innervation | superior gluteal |
| A well developed gluteus ______ provides great drive in the leg | minimus |
| What factors determine hip range of motion | lean tissue, adipose tissue, tendon length, muscle density, previous injury |
