Which structure is located on the sternum?
Hyoid bone
Xiphoid process
Ossa coxae
Sesamoid bone
Correct Answer : B
The xiphoid process is a small, cartilaginous extension located at the inferior end of the sternum (breastbone), which serves as an attachment site for certain abdominal muscles. The hyoid bone is a U- shaped bone located in the neck, not on the sternum. The ossa coxae are also known as the hip bones, which are in the pelvic region, not on the sternum. Sesamoid bones are small, rounded bones that are embedded within tendons and can be found in various locations throughout the body, but not necessarily on the sternum.

It also has antibacterial properties that help to protect the ear from infection. The amount and composition of ear wax vary from person to person and can be affected by factors such as age, genetics, and environmental conditions.

This condition is harmless and is caused by the betalain pigments present in these vegetables.

Rice and eggs, carrots and squash, spinach and mustard greens are not known to cause unusual skin color. However, it is important for the nurse to ask the client about her diet and any supplements she may be taking to beter understand the cause of the unusual skin color.
