Gluteal Region Flashcards
2 bones of the gluteal region
- Pelvic bone
- Femur
Large ball and socket joint between pelvis and femur. Only joint in the pelvis.
Hip joint
What are the bones comprising the bony pelvis?
Hip bones + sacrum + coccyx
Point at which the hip bones unite anteriorly
Symphysis pubis
Bone that attaches the LL to the axial skeleton with the strongest ligaments of the body
Pelvis
Bone that transmits weight of the upper body to the lower limbs
Pelvis
What are the 3 structures comprising the coxal bones
Ilium, Ischium, Pubis (separate bones in childhood, but will eventually fuse)
Deep hemispherical socket on lateral pelvic surface
Acetabulum
Articulates with the head of the femur to form the hip joint
Acetabulum
A large flaring bone that forms the superior region of the coxal bone. It consists of a body and superior winglike portion.
Ilium
Whatchu call the superior winglike portion of the ilium?
Ala
Major markings of ilium
- Tubercle of iliac crest
- a,p,i gluteal lines
- a&p superior iliac spines
- a&p inferior iliac spines
2 surfaces of ilium
GLUTEAL SURFACE (broad posterolateral surface) AURICULAR SURFACE (articulates with sacrum @ sacroiliac joint)
It forms the posteroinferior part of the hip bone
Ischium
Thick body of ischium articulates with?
Ilium (Thinner ramus articulates with pubis)
Major markings of ischium
- Ischial spine
- LESSER sciatic notch
- ischial tuberosity
Strongest part of the hip bone. Used when sitting.
Ischial tuberosity
Forms the anterior portion of hip bone
Pubis
What joins the 2 pubic bones (pubic symphysis) at the midline
Fibrocartilage
Major marking present in all coxal bones (ilium, ischium, pubis)
Obturator foramen
Pelvis inferior to pelvic brim. Forms a bowl containing pelvic organs. Defines birth canal (in females opkors)
True (lesser) pelvis
False (greater) Pelvis - bounded by alae of iliac bones
Pelvis that is tilted forward. Cavity is broad, shallow, and has greater capacity. Also, lighter, thinner, smoother
Female Pelvis
Male Pelvis - less forward, narrow and deep cavity, heavier, thicker, prominent markings
What are the bones comprising the bony pelvis?
Hip bones + sacrum + coccyx
Point at which the hip bones unite anteriorly
Symphysis pubis
