Bones Of The Lower Extremity Flashcards
The pelvic girdle and lower extremities consist of these many bones
What are 62 bones?
The pelvic girdle and lower extremities are part of the skeletal system
What is the appendicular skeleton system?
The right and left hip bone, as well as the sacrum and coccyx are the four bones that make up this
What is the pelvic girdle?
Anteriorly these two hipbones unite to form this joint
What is the pubis symphysis?
Posteriorly the two hip bones unite with the sacrum to form this joint
What is the sacroiliac joint?
This is described as a complete ring of bone, or a deep basin-like structure, formed by the two hipbones, the pubis symphysis, and the sacrum
What is the bony pelvis?
As infants, this hip bones are in these three pieces are united by cartilage and by the time we’re 23 years old, these pieces would have fused together completely (what are the name of the three pieces)
The ilium, ischium, and the pubis
This part of the HIP bone is the most superior and largest part of the hip bone.
What is the ilium?
This is known as the most superior border of the ilium.
What is the iliac crest?
Located below the posterior superior iliac spine, is this notch, which allows for the passage of the sciatic nerve, the longest nerve in the body
 What is the greater sciatic notch?
The iliac crest end anteriorly as this
What is the anterior superior iliac spine?
The iliac crest ends posteriorly as this
What is the posterior superior iliac spine?
The function of the anterior and posterior iliac spine is a point of attachment for this
What are muscles of the abdominal wall?
This posterior inferior portion of the pelvic girdle is what we are known to sit on
What is the ischium?
This anterior inferior portion of the pelvic girdle, unites anteriorly to form the pubic symphysis
What is the pubis bone?
This consist of a disc of fibrocartilage, which is the hardest cartilage located adjacent to the pubis bone.
What is the pubis symphysis?
This deep fossa is formed by the fusion of the ilium, pubis, and ischium, and articulates with the head of the femur to form the coxal joint, a.k.a. hip joint.
What is the acetabulum?
This is the largest Foreman in the entire skeleton of the entire human body, between the pubis in the ischium, and although covered by a membrane is still allows blood vessels and nerves to pass through
What is the obturator foramen
This is the largest, the heaviest, and the strongest bone in the human body
What is the femur?
This articulates with the acetabulum of the hip bone.
What is the head of the femur?
