    What are the four main functions of the skin?

    • Protection,regulation,sensory reception,secretion

    • Cooling,heating,sun block,blood flow

    Correct Answer
    A. Protection,regulation,sensory reception,secretion
    Explanation
    The skin serves as a protective barrier for the body, preventing harmful substances from entering and protecting against physical injuries. It also helps regulate body temperature by sweating and controlling blood flow to the skin's surface. The skin contains sensory receptors that allow us to perceive touch, pressure, pain, and temperature. Additionally, the skin secretes sweat, oil, and other substances that help moisturize and protect the skin.

    The skin is essentially composed of two layers what are they called?

    • Nerves,cells

    • Dermis,nerves

    • Epidermis,dermis

    • Nails,hair

    Correct Answer
    A. Epidermis,dermis
    Explanation
    The skin is composed of two main layers: the epidermis and the dermis. The epidermis is the outermost layer of the skin and it acts as a protective barrier against the environment. It is made up of cells that constantly regenerate and shed. The dermis is the layer beneath the epidermis and it contains various structures such as blood vessels, nerves, and hair follicles. The dermis provides support and nourishment to the epidermis.

    A pigment that gives color to the skin

    • Papillae

    • Sebaceous

    • Dermis

    • Melanin

    Correct Answer
    A. Melanin
    Explanation
    Melanin is a pigment that gives color to the skin. It is produced by cells called melanocytes, which are located in the epidermis, the outermost layer of the skin. Melanin is responsible for determining the color of our hair, eyes, and skin. It helps protect the skin from the harmful effects of UV radiation by absorbing and scattering the rays. The amount and type of melanin in the skin vary among individuals, resulting in different skin tones and colors.

    The cresent shaped white area of the nail is called the lunula

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The crescent-shaped white area of the nail is called the lunula. This is a correct statement. The lunula is the visible part of the nail matrix, which is the area where new nail cells are formed. It appears as a whitish, half-moon shape at the base of the nail. The size and visibility of the lunula may vary among individuals, but it is generally present on most nails.

    What is the protein substance that is the basic structural component for hair and nail?

    • Vitamin c

    • Vitamin d

    • Keratin

    • Fiber

    Correct Answer
    A. Keratin
    Explanation
    Keratin is the correct answer because it is a protein substance that serves as the basic structural component for both hair and nails. Keratin is a fibrous protein that provides strength and durability to these structures. Vitamin C and vitamin D are not protein substances and do not play a role in the structural component of hair and nails. Fiber, while important for overall health, is not specifically related to the structure of hair and nails.

    Hair,Nails,sebaceous glands and sudeforious (sweat) glands are the four accessory structures of the skin 

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The statement is true because hair, nails, sebaceous glands, and sweat glands are indeed considered as the four accessory structures of the skin. These structures play important roles in maintaining the health and functionality of the skin. Hair helps protect the skin from external factors, nails provide support and protection to the fingertips, sebaceous glands produce sebum that moisturizes and protects the skin, and sweat glands help regulate body temperature by producing sweat.

    Germinativum,spinosum,granulosum,lucidum and corneum are the five "Strata" of the epidermis 

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The epidermis is the outermost layer of the skin, and it is composed of several layers called "strata." These layers include the germinativum, spinosum, granulosum, lucidum, and corneum. Each layer has a specific function and plays a role in protecting the body from external factors such as bacteria and UV radiation. Therefore, the statement that germinativum, spinosum, granulosum, lucidum, and corneum are the five "strata" of the epidermis is true.

    The two layers of the dermis are called the

    • Receptor,gland

    • Arrector,hair

    • Sensory,nerve

    • Papillary,reticular

    Correct Answer
    A. Papillary,reticular
    Explanation
    The two layers of the dermis are called the papillary and reticular layers. The papillary layer is the outermost layer of the dermis and is responsible for providing nutrients and oxygen to the epidermis. It also contains nerve endings and blood vessels. The reticular layer is the deeper layer of the dermis and is made up of dense connective tissue. It provides strength and elasticity to the skin and contains sweat glands, hair follicles, and sensory receptors.

    What is the primary organ of the integumentary system?

    • Sweat glands

    • Epidermis

    • Dermis

    • Nerve

    Correct Answer
    A. Epidermis
    Explanation
    The primary organ of the integumentary system is the epidermis. The epidermis is the outermost layer of the skin and serves as a protective barrier against external factors such as pathogens, UV radiation, and dehydration. It also helps regulate body temperature and contains melanocytes that produce melanin, which gives color to the skin. The sweat glands, dermis, and nerves are important components of the integumentary system, but they are not considered the primary organ.

    What is known as the corium or true skin?

    • Epidermis

    • Dermis

    • Pigment

    • Nerves

    Correct Answer
    A. Dermis
    Explanation
    The corium or true skin is known as the dermis. The dermis is the layer of skin located beneath the epidermis. It contains various structures such as blood vessels, sweat glands, hair follicles, and nerve endings. The dermis provides support and strength to the skin and helps regulate body temperature. It also plays a crucial role in sensation, as it contains sensory receptors for touch, pressure, pain, and temperature.
