The sacrum can be considered an extension of the spinal column with ______ fused vertebrae.

5

The hip, or _____________________ is a relatively stable joint due to its bony architecture, strong ligaments and large supportive muscles.

acetabular femoral joint

The _____________ _______________ serves to provide points of origin for muscles generally involved in flexing the hip.

anterior pelvis

The hip joint is what kind of joint?

ball and socket joint

Laterally, the __________ _____________ inserts primarily on the head of the fibula, with some fibers attaching on the lateral tibial condyle.

biceps femoris

Extending inferior from the sacrum is the __________?

coccyx

What is the longest bone in the body?

femur

What is the longest muscle in the body?

Sartorius

Posteroinferiorly, the _________________ __________________ serves as the point of origin for the hamstrings, which extend the hip.

ischial tuberosity

what is the posterior and lower two fifths of pelvic bone?

ischium

The ____________ ______________ is the point of insertion for all of the gluteal muscles and five of the six deep external rotators.

greater trochanter

What does the hip joint consist of?

head of the femur connecting with the acetabulum of the pelvic girdle

what is the upper two fifths of pelvic bone?

ilium

Distally, the ____________ serves as a major bony landmark to which all 4 quadriceps muscles attach and ultimately insert on the tibial tuberosity via the patella tendon.

patella

The _______________ _______________ generally serves as a point of insertion for some of the short muscles of the hip and as the origin for three of the knee extensors

proximal thigh

Anteriorly, the 3 vasti muscles of the quadriceps originate __________?

proximally

what is the anterior and lower one fifth of pelvic bone?

pubis

What is the only quadricep muscle that suffers from bi-articular insufficiencies? (2-joint muscle)

rectus femoris

The ________________ inserts posteromedially on the medial tibial condyle

semimembranosus

What 3 bones make up the pelvic bones?

the ilium, the ischium, and the pubis

What serves as the point of origin for the hip adductors, which include the adductor magnus, adductor longus, adductor brevis, pectineus, and gracilis?

the pubis and its inferior ramus

The acetabular femoral joint (the hip) functions in what?

weight bearing and locomotion (enhanced significantly by the hips wide range of motion)

Where does the sartorius originate?

on the anterior superior iliac spine (ASIS)

The sartorius, gracilis, and semitendinosus insert where?

on the upper anteromedial surface of the tibia just below the medial condyle, after crossing the knee posteromedially

where do the the gluteus medius and minimus originate?

(laterally) on the posterior iliac crest as well as the posterior sacrum and coccyx

Anterolaterally, ____________ ________________ provides the insertion point for the iliotibial tract of the tensor fasciae latae

Gerdy's tubercle

Internal and external rotation of the hip occur in which plane of motion?

Transverse plane

This muscle is occasionally blamed in part for common lateral patellar subluxations & dislocations?

Vastus lateralis

the gluteus medius and minimus __________ the hip

abduct

Where does the tensor fascia latae arise?

from the anterior iliac crest

Although not palpable, the _____________ _______________ serves as the bony landmark upon which the iliopsoas inserts

less trochanter

Posteriorly, the _________ __________ serves as the insertion for the hip adductors.

linea aspera

What does the pelvic girdle consist of?

right and left pelvic bone joined together posteriorly by the sacrum
