Anterior Pelvic Girdle & Thigh

Bony landmarks of the pelvis

100

This structure is formed by the junction of the two pubis bones:

Pubic symphysis

200

This pelvic bony landmark serves as the proximal attachment for the sartorius:

Anterior Superior Iliac Spine (ASIS)

300

This structure of the pelvis is referred to as the superolateral margin of the pelvis and serves as an attachment site for the external oblique:

Iliac crest

400

This is created by the junction of the pubis and the ischium and allows for the passage of nerves, arteries, and veins.

Obturator foramen

500

These TWO pelvic bony landmarks serve as the proximal attachments of the rectus femoris:

Anterior INFERIOR Iliac Spine (AIIS)

External surface of the groove superior to the acetabulum

Bony landmarks of the femur

100

What are the three main portions of the femur?

Head, neck, and shaft

200

This femoral bony landmark is a large, irregular, eminence lateral and slightly posterior (1 cm) to the head of the femur

Greater trochanter

300

This superior landmark of the femur serves as a proximal attachment for vastus medialis:

Intertrochanteric line

400

This eminence serves as the distal attachment of pes anserinus:

Gerdy's tubercle

500

The muscles which join to form pes anserinus:

Gracilis

Sartorius

Semitendinosus

Muscles of the Ant. Pelvis

100

Which muscle functions as the primary flexor of the hip?

Iliopsoas

200

This muscle proximally attaches to the lateral sides of T12 and L1, the intervertebral disc between these vertebrae, and assists in trunk flexion

Psoas minor

300

In the event of an anterior pelvic tilt, the ischium moves in the sagittal plane in which direction(s)?

Posteriorly and superiorly

400

In addition to flexing the hip and providing stabilization, the iliopsoas also allows for ________ ________ of the hip:

External rotation

500

Explain how activation of the iliopsoas aids in external rotation:

Since the lesser trochanter is directed posteriorly and the proximal attachment of iliopsoas is located medially and anteriorly, contraction results in external rotation along the axis of the hip joint

Muscles of the Ant. Thigh

100

What does quadriceps femoris refer to?

The four quad muscles: rectus femoris, vastus lateralis, vastus medialis, and vastus intermedius

200

This quad muscle is the only one which assists hip flexion... AND WHY?

The rectus femoris is the only quad muscle to cross both the knee and hip joints

300

This refers to a group of quad muscle fibers which pull medially rather than superiorly:

Vastus medialis oblique (VMO)

400

This quadriceps muscle is distinguishable by its smaller belly and larger aponeurosis:

Vastus intermedius

500

What are the FIVE actions of the tensor fascia latae?

Hip abduction, internal rotation, hip flexion, knee extension, steadies trunk on thigh

Adductors & Femoral Triangle

100

Adduction of the hip occurs in this plane and along this axis (2)?

The frontal plane, and z axis

200

This adductor has both adductor and hamstring portions

Adductor magnus

300

This nerve innervates adductor longus, gracilis, adductor brevis, and the adductor portion of adductor magnus

Obturator nerve

400

This serves as the distal attachment of adductor longus:

The middle third of the linea aspera

500

Describe the superior, medial, and lateral borders of the femoral triangle:

Superior - inguinal ligament

Medial - adductor longus

Lateral - sartorius
