Ceruminous glands secrete?
Ear wax
Keratin
Sebum
Mucus
The Correct Answer is A
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 ABCD rule is a mnemonic used to identify the characteristics of melanoma, which is a type of skin cancer. The leters stand for:
A -Asymmetry: One half of the mole or lesion does not match the other half.
B - Border irregularity: The edges are ragged, notched, or blurred.
C - Color: The color is not uniform and may include different shades of brown or black, or sometimes patches of pink, red, white, or blue.
D - Diameter: The size of the mole or lesion is greater than 6 mm (about the size of a pencil eraser), although melanomas can sometimes be smaller.
This rule is not as useful in detecting other types of skin cancer, such as squamous cell carcinoma, basal cell carcinoma, or sarcoma, as they tend to have different characteristics. However, any new or changing mole or lesion on the skin should be examined by a dermatologist to determine if it is cancerous.
Correct Answer is B
Explanation
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.
