horseshoe shape

What forms the acetabulum and what shape does the articular cartilage look like?

four fused vertebrae of the base of your spinal cord

What is the coccyx?

what is the function of the coccyx?

coccyx

head of the femur

fovea of the femur

greater trochanter

lesser trochanter

intertrochanteric line (anterior)

intertrochanteric crest (posterior)

gluteal tuberosity

linea aspera

gluteus minimus and medius

Identify a muscle that has an attachment on the greater trochanter?

iliopsoas

Identify a muscle that has an attachment on the lesser trochanter?

gluteus maximus

identify a muscle that attaches on the gluteal tuberosity

Adductors and vastus muscles

identify a muscle that attaches on the linea aspera

Surfaces: bodies of two pubic bones

Joint: cartilaginous; symphysis (fibrocartilage pad)

What are the articulating surfaces of the pubic symphysis and what is the joint classification?

Ligaments: Superior and inferior pubic ligament

Muscles: rectus abdominis, adductor longus

What are the stabilizing ligaments and muscles of the pubic symphysis?

Anterior: auricular surfaces of the ilium and sacrum

Posterior: tuberosities of the ilium and sacrum

What are the anterior and posterior articulating surfaces of the sacroiliac joint?

Anterior: synovial plane(gliding) joint

Posterior: Fibrous Syndesmosis Joint

What is the joint classification of the sacroiliac joint?

interosseous sacroiliac ligament

anterior/posterior sacroiliac ligament

sacrospinous ligament

sacrotuberous ligament

What are the stabilizing ligaments of the sacroiliac joint?

Surfaces: acetabulum and femoral head

Joint: synovial, ball and socket

What are the articulating surfaces and joint classification of the hip joint?

labrum, capsule, and ligaments

What are some of the structures that stabilize the hip joint?

fibrocartilage ring surrounding the acetabulum

functions to increase the congruency/ stability of the joint and it provides shock absorption

What is the labrum of the hip joint and what does it do?

reinforces the hip joint by its strong dense fibrous nature

attaches at the edge of the acetabulum and the intertrochanteric line and crest

What does the joint capsule do at the hip joint and where does it attach?

iliofemoral ligament

anterior, shaped like an inverted Y; from the iliac portion of the acetabular rim to the intertrochanteric line and limits excessive hip extension and external rotation

ischiofemoral ligament

posterior; from the ischial portion of the acetabular rim to the greater trochanter and limits excessive hip extenison and internal rotation

pubofemoral ligament

anterior and inferior; from the pubic portion of the acetabular rim to blend with the joint capsule; limits excessive hip extension, abduction, and external rotation

Teres ligament

attaches from deep in the acetabulum to the fovea in the head of the femur, and it functions to stabilize the internally and to supply blood

become tight/taunt, which draws the head of the femur into the acetabulum, limiting hip extension ROM

the ligaments unwind which allows for a good amount of ROM

In general what do the hip ligaments do during hip extension? During hip flexion?

trochanteric bursa, gluteus medius bursa, iliopsoas bursa, ischial bursa

What are the different bursa found at the hip joint?

Flexion/extension, adduction/abduction, internal/external rotation, diagonal abduction and adduction, horizontal abduction and adduction, circumduction
