Bony landmarks of the pelvis
This structure is formed by the junction of the two pubis bones:
Pubic symphysis
What are the three main portions of the femur?
Head, neck, and shaft
Which muscle functions as the primary flexor of the hip?
Iliopsoas
What does quadriceps femoris refer to?
The four quad muscles: rectus femoris, vastus lateralis, vastus medialis, and vastus intermedius
Adduction of the hip occurs in this plane and along this axis (2)?
The frontal plane, and z axis
This pelvic bony landmark serves as the proximal attachment for the sartorius:
Anterior Superior Iliac Spine (ASIS)
This femoral bony landmark is a large, irregular, eminence lateral and slightly posterior (1 cm) to the head of the femur
Greater trochanter
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
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
This adductor has both adductor and hamstring portions
Adductor magnus
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
This superior landmark of the femur serves as a proximal attachment for vastus medialis:
Intertrochanteric line
In the event of an anterior pelvic tilt, the ischium moves in the sagittal plane in which direction(s)?
Posteriorly and superiorly
This refers to a group of quad muscle fibers which pull medially rather than superiorly:
Vastus medialis oblique (VMO)
This nerve innervates adductor longus, gracilis, adductor brevis, and the adductor portion of adductor magnus
Obturator nerve
This is created by the junction of the pubis and the ischium and allows for the passage of nerves, arteries, and veins.
Obturator foramen
This eminence serves as the distal attachment of pes anserinus:
Gerdy's tubercle
In addition to flexing the hip and providing stabilization, the iliopsoas also allows for ________ ________ of the hip:
External rotation
This quadriceps muscle is distinguishable by its smaller belly and larger aponeurosis:
Vastus intermedius
This serves as the distal attachment of adductor longus:
The middle third of the linea aspera
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
The muscles which join to form pes anserinus:
Gracilis
Sartorius
Semitendinosus
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
What are the FIVE actions of the tensor fascia latae?
Describe the superior, medial, and lateral borders of the femoral triangle:
Superior - inguinal ligament
Medial - adductor longus
Lateral - sartorius
