Question

Acetabulum is located in-
A. Collar bone
B. Hip bone
C. Shoulder bone
D. Thigh bone

Answer 1

Hint: An acetabular fracture is a break in the socket portion of the "ball-and-socket" in the hip joint. These hip socket fractures are not normal, they occur much less frequently than other fractures of the upper femur or femoral head that is the ball portion.

Complete answer:
Option A – Collar bone also known as clavicle, is a long bone that plays the role as a strut between the shoulder blade and the sternum generally called breastbone. There are two types of collar bone one on the left and other one on the right. It is a touchable bone, as well as in people who have less fat in this region. The location of the collar bone is clearly visible, as it creates a bulge in the skin near the neck area.
Option B – The hip bone comprises the three main parts; the ilium, pubis as well as ischium. Prior to puberty, the triradiate cartilage separates these three parts along with it starts the fusion that takes place only at the age of 15-17. Together the three parts, the ilium, pubis and ischium form a cup-shaped socket called the acetabulum whose literal meaning in Latin is 'vinegar cup'.
Option C - The human shoulder is made up of three bones: collarbone, shoulder blade as well as the upper arm bone along with associated muscles, ligaments as well as tendons.
Option D – The femur generally recognized as thigh bone, is the proximal bone of the hind limb in tetrapod vertebrates. The head of the bone articulates with the acetabulum in the pelvic bone forming the hip joint.

Thus, the right answer is Option B “Hip-Bone".

Note: The Acetabulum in the hip is made up of three bones. The ischium contributes a little more than two-fifths of the structure. And the ilium forms the upper boundary whereas the rest is formed by the pubis, near the midline.
