Question 1 of 5
Mammalian skin is primarily meant for -
Correct Answer: D
Rationale: The correct answer is D: Acting as a receptor organ. Mammalian skin contains sensory receptors for touch, pressure, pain, temperature, and vibration. These receptors play a crucial role in detecting and responding to external stimuli, aiding in survival. Skin is not primarily meant for A: The removal of excess water, as this function is mainly carried out by the kidneys. Skin does not excrete urea, making B incorrect. Skin is not responsible for storage of food, making C an incorrect choice. Thus, the correct answer is D as skin primarily acts as a receptor organ for sensory perception.
Question 2 of 5
Study of skin is known as-
Correct Answer: B
Rationale: The correct answer is B: Dermatology. Dermatology is the branch of medicine that deals with the study of skin and its diseases. "Hypology" (Choice A) is not a recognized term related to skin study. "Tricology" (Choice C) is the study of hair and scalp, not skin. "Mastology" (Choice D) is the study of breast diseases, not skin. Therefore, the correct term for the study of skin is Dermatology.
Question 3 of 5
Highly odorous and characteristic smell of rabbits is by a milky secretion of-
Correct Answer: B
Rationale: The correct answer is B: Perineal glands. Rabbits produce a highly odorous and characteristic smell through their perineal glands. These glands are located near the anus and secrete a substance that helps rabbits communicate through scent marking. A: Tarsal glands are located on the legs of deer and are not related to rabbits' distinctive smell. C: Zeis glands are associated with eyelashes and are not responsible for the odor produced by rabbits. D: "None of these" is incorrect as perineal glands are indeed responsible for the odor in rabbits. In summary, the perineal glands in rabbits secrete a substance that gives them their unique smell, making choice B the correct answer.
Question 4 of 5
The layer of the skin that contains the blood vessels and nerves that are closest to the surface of the skin is the ______ layer.
Correct Answer: B
Rationale: The correct answer is B: Papillary. This layer is located right below the epidermis, contains blood vessels, nerves, and capillaries closest to the skin surface, aiding in temperature regulation and sensation. The subcutaneous layer (A) is deeper and primarily consists of fat cells. The reticular layer (C) is deeper than the papillary layer and mainly provides structural support. Hypodermal (D) is not a recognized skin layer term. Thus, the papillary layer is the correct choice due to its proximity to the skin surface and functions related to blood vessels and nerves.
Question 5 of 5
Water loss due to evaporation of a fluid that has penetrated through the skin is termed:
Correct Answer: B
Rationale: The correct answer is B: Latent. Evaporation of a fluid through the skin is considered latent water loss because it occurs without any noticeable signs or symptoms. This type of water loss is not easily perceptible and may not be readily apparent to an individual. Sensible water loss (choice A) refers to water loss that is easily measurable, such as through sweating. Intensible (choice C) and discrete (choice D) are not terms used to describe water loss through evaporation of fluids. Therefore, the correct term for water loss due to evaporation through the skin is latent.
