    Correct Answer
    A. Hair stream
    Explanation
    A hair stream refers to the direction in which the hair flows, which is determined by the angle at which the hair follicles are inclined. When the follicles slope in the same direction, the hair flows in that same direction, creating a hair stream. This can be observed when all the hairs on a person's head or a certain area of their head flow in a consistent direction. The other options, helix, cowlick, and whorl, do not specifically refer to the direction of hair flow and are therefore not the correct answer.

      Wave pattern

    Correct Answer
    A. Cowlick
    Explanation
    A cowlick is a tuft of hair that stands straight up, often against the natural direction of hair growth. This can create a noticeable and sometimes unruly patch of hair that is difficult to style or control. Cowlicks are commonly found on the crown of the head and can vary in size and shape. They are caused by the hair follicles growing in a different direction or at a different angle than the surrounding hair.

      Catagen phase

    • C.

      Cowlick

    • D.

      Medulla

    Correct Answer
    A. Cortex
    Explanation
    The middle layer of the hair is called the cortex. It is made up of elongated cells that contain a fibrous protein core and melanin pigment. The cortex is responsible for giving hair its strength, elasticity, and color. It also helps to protect the innermost layer of the hair, called the medulla. The catagen phase is a transitional phase in the hair growth cycle, and a cowlick is a section of hair that grows in a different direction than the rest of the hair.

    Also known as growth phase; phase during which new hair is produced.

    • A.

      Anagen phase

    • B.

      Catagen phase

    • C.

      Telogen phase

    • D.

      Side bonds

    Correct Answer
    A. Anagen phase
    Explanation
    The anagen phase is the phase during which new hair is produced. This is the active growth phase of the hair follicle, where the hair cells divide rapidly and the hair strand grows longer. During this phase, the hair follicle is attached to the dermal papilla and receives nourishment from it. The anagen phase can last for several years, and the length of this phase determines the length of the hair strand.

      Monilethrix

    • B.

      Ringed hair

    • C.

      Scutula

    • D.

      Tinea favosa

    Correct Answer
    A. Monilethrix
    Explanation
    Monilethrix is the correct technical term for beaded hair. This condition is characterized by hair shafts that appear beaded or have constrictions at regular intervals, giving the hair a necklace-like appearance. It is a rare genetic disorder that affects the hair follicles, causing weak and brittle hair that easily breaks or falls out. The term "ringed hair" refers to a different condition called trichorrhexis nodosa, which is characterized by nodes or knots along the hair shaft. Scutula and tinea favosa are not related to beaded hair.
