Which structure is located on the sternum?
Hyoid bone
Xiphoid process
Ossa coxae
Sesamoid bone
The Correct Answer is B
The xiphoid process is a small, cartilaginous extension located at the inferior end of the sternum (breastbone), which serves as an atachment 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.

Explanation
Ceruminous glands are specialized sweat glands located in the skin of the ear canal. These glands secrete a waxy substance called cerumen or ear wax. Ear wax helps to lubricate and protect the skin of the ear canal and prevent the entry of foreign particles, such as dust and insects, into the ear. 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.
Correct Answer is C
Explanation
The popliteal artery is located behind the knee and is one of the major arteries that supplies blood to the leg and foot. Palpating the pulse in this artery can be done by pressing firmly on the area behind the knee, just below the crease. It is important to note that palpating the pulse in this area can be more difficult than other pulse points, as the artery is deep and surrounded by other structures such as muscle and bone.
