Question

Complete the following paragraph by selecting the correct option. Pelvic girdle consists of two coxal bones. Each coxal bone is formed by the fusion of three bones , and . At the point of fusion of the above bones is a cavity called to which the thigh bone articulates. The two halves of the pelvic girdle meet ventrally to form the pubic symphysis containing cartilage.

• A. a
• B. b
• C. c
• D. d

Answer 1

The Correct Option is D

Answer (d) d

Answer 2

Ans. The hip bone, also known as the coxal bone, is a big, crooked bone that is enlarged above and below and restricted in the middle. Ilium, ischium, and pubis are its three component components.

The concave surface of the pelvis is known as the acetabulum. The hip joint is created when the head of the femur connects to the pelvis at the acetabulum.

Fibrocartilage makes up the pubic symphysis joint.

Ilium

The superior, or upper, portion of the hip bone is made up of the ilium. 

• The body and the wing or tail of the ilium are the two main sections of the lower area close to the acetabulum that makes up the ilium. 
• The iliac crest is located at the top of the wing-lock section of the ilium, which may be felt on the sides of your abdomen with your hand. 
• This makes it possible for different muscles to connect. 
• The anterior superior iliac spine is the name for the top or superior spine. 
• It permits the inguinal ligament's connection. 
• The rectus femoris muscle and iliofemoral ligament of the hip joint can be attached to the inferior iliac spine. 
• A portion of the posterior sacroiliac ligaments can be attached to one of the two iliac spines, the posterior superior iliac spine. 
• The posterior inferior iliac spine is shown below. 
• Inferior implies away from the head or towards the feet, while posterior indicates in the direction of the back. 
• The sciatic nerve can travel through a larger sciatic notch. 
• Finding the hip bone's posterior portion now will be useful. 

Ischium 

There are two major geographic divisions a structure referred to as the Ischial spine. 

• Another notch known as the lower sciatic notch is located below the ischial spine and enables for the numerous muscles and ligaments.  
• The lateral aspect of the Ischium has a rough and uneven Ischial tuberosity. 
• It permits the sacrotuberous ligament and a number of muscles to connect.

Pubis

The front or front side of the hip bone is referred to as the pubis or pubic region.  

• The top, branching section of the pubis is known as the superior ramus. 
• The pectineal line is a ridge that runs along this ramus' superior border. 
• It enables several muscles and ligaments to connect.
