Question

The vertebral column is connected to the pelvic girdle in the
A. Coccygeal region
B. Sacral region
C. Lumbar region
D. Cervical region

Answer 1

The human pelvic girdle or the hip region is composed of 3 pelvic bones namely the ilium, ischium, and pubis. These bones are attached to the vertebral column, further, they are acted to the femur using a cavity known as acetabulum.

Complete answer: In the human vertebrae, four types of bones are present namely the cervix, thoracic, lumbar, and sacral bone. Below the sacrum bone coccyx born is also present which is said to be vestigial in the case of humans. It is also known as the tailbone. The cervical vertebra is connected to the cervical region, while the thoracic region is said to join to the ribs. The pelvic girdle is connected to the sacral bone, which is a combination of 5 fused bones.
Hence, the correct option is (B), i.e., Sacral region.
Additional Information:
The following are the functions of the human skeletal system-
1. It provides structure to the human body and supports the human structure.

3. It provides the human body with a definite shape and structure.
4. It helps in providing movement to the body by means of tendons and ligaments wherein bones are attached to the muscles and two bones attached respectively.
5. Bone marrow is also important for the formation of RBC or red blood cells in the human body.

Note: It should be noted that the sacral bone is attached to the pelvic girdle using the ilium, ischium, and pubis which are also known as the pelvic bones. The acetabulum cavity is also present to which the femur is attached.
