What is the function of the sebaceous gland?
To secrete cerumen, or earwax
To produce hair growth
To produce sebum or oil
To excrete perspiration, or sweat
Correct Answer : C
Sebaceous glands are microscopic glands in the skin that secrete an oily or waxy substance called sebum into the hair follicles or onto the skin surface.
Sebum lubricates and protects the skin and hair from drying out and from infections caused by bacteria or fungi. Sebum also contributes to body odour.
A. To secrete cerumen or earwax. This statement is wrong because cerumen is produced by specialized sweat glands in the ear canal, not by sebaceous glands. B. To produce hair growth.
This statement is wrong because hair growth is determined by the activity of hair follicles, not by sebaceous glands. Sebaceous glands only deposit sebum on the hairs and bring it to the skin's surface.
D. To excrete perspiration or sweat.
This statement is wrong because perspiration is produced by sweat glands, not by sebaceous glands. Sweat glands are different from sebaceous glands in their structure, location and function. Sweat glands help regulate body temperature and eliminate waste products through the skin.

Correct Answer is D
Explanation
Chemoreceptors are specialized sensory receptors that detect changes in the chemical composition of the blood, such as the partial pressure of oxygen (PO2) and carbon dioxide (PCO2) and the pH level.
Chemoreceptors can be classified into two types: peripheral and central. Peripheral chemoreceptors are located in the aortic and carotid bodies and they mainly respond to low PO2, but also to high PCO2 and low pH. Central chemoreceptors are located in the brainstem and they mainly respond to high PCO2 and low pH, which reflect the concentration of hydrogen ions in the cerebrospinal fluid. Both types of chemoreceptors send signals to the respiratory and cardiovascular centers in the brainstem, which regulate breathing and blood pressure accordingly.
Increase in blood pressure. This statement is wrong because blood pressure is not directly sensed by chemoreceptors, but by baroreceptors, which are different types of sensory receptors located in the walls of blood vessels. Decrease in heart rate. This statement is wrong because heart rate is not directly sensed by chemoreceptors, but by cardiac receptors, which are different types of sensory receptors located in the atria and ventricles of the heart.Pulmonary congestion. This statement is wrong because pulmonary congestion is not directly sensed by chemoreceptors, but by pulmonary stretch receptors, which are different types of sensory receptors located in the lungs
Correct Answer is B
Explanation
Fallopian tubes. Fertilization of an ovum usually takes place in the uterine tube, also known as the fallopian tube. This is the structure that transports the ovum from the ovary to the uterus.
Choice A is wrong because the cervix is the lower part of the uterus that connects to the vagina. It does not receive or transport the ovum.
Choice C is wrong because the ovaries are the organs that produce and release the ova. They do not host the fertilization process.
Choice D is wrong because the horn of the uterus is the point where the uterine tube joins the uterus. It is not the site of fertilization.
The normal range of temperature for human body is 36.5–37.5 °C (97.7–99.5 °F).
Correct Answer is C
Explanation
The dermis is the layer of the cutaneous membrane that contains nerve endings, blood vessels, glands, and hair follicles.
The cutaneous membrane is another name for the skin, which is composed of two main layers: the epidermis and the dermis.
Choice A is wrong because fascia is not a layer of the cutaneous membrane, but a type of connective tissue that surrounds muscles, organs, and other structures.
Choice B is wrong because subcutaneous is not a layer of the cutaneous membrane, but a layer of fat and connective tissue that lies below the dermis.
Choice D is wrong because epidermis is the outermost layer of the cutaneous membrane, which provides protection and waterproofing, but does not contain nerve endings.
Correct Answer is C
Explanation
The esophagus is located in the thoracic cavity, which is the space between the lungs and the chest wall. The thoracic cavity also contains the heart, aorta, trachea, thymus gland, bronchial tubes, and many lymph nodes.
Choice A is wrong because the ventral cavity is a general term for the body cavity that includes the thoracic and abdominal cavities.
Choice B is wrong because the abdominal cavity is the space below the diaphragm that contains the stomach, small and large intestines, spleen, pancreas, liver, and gallbladder.
Choice D is wrong because the dorsal cavity is another general term for the body cavity that includes the cranial and spinal cavities.
