    Which is true about the hair follicle

    • A.

      Each hair follicle lives in a cycle consisting of a short period of growth followed by a relatively long period of rest

    • B.

      Each hair follicle lives in a cycle consisting of a long period of growth followed by a relatively short period of rest

    Correct Answer
    B. Each hair follicle lives in a cycle consisting of a long period of growth followed by a relatively short period of rest
    Explanation
    Each hair follicle lives in a cycle consisting of a long period of growth followed by a relatively short period of rest. This means that hair follicles go through a process called the hair growth cycle, which includes anagen (the active growth phase) and telogen (the resting phase). During the anagen phase, the hair follicle grows and produces new hair, while during the telogen phase, the hair follicle rests and no new hair is produced. This cycle repeats itself throughout a person's life, resulting in the continuous growth and shedding of hair.

    Rate this question:

  • 36. 

    Which are correct? .

    • A.

      After the resting phase the hair is shed and a newer hair begins to grow, thus, starting a new hair growth cycle

    • B.

      After the resting phase the hair is shed but no new hair begins to grow, thus, starting a new hair growth cycle

    • C.

      During the rest period the hair is still attached to the hair follicle, but it is not growing

    • D.

      During the rest period the hair is not attached to the hair follicle, but it is not growing

    Correct Answer(s)
    A. After the resting phase the hair is shed and a newer hair begins to grow, thus, starting a new hair growth cycle
    C. During the rest period the hair is still attached to the hair follicle, but it is not growing
    Explanation
    During the resting phase of the hair growth cycle, the old hair is shed and a new hair begins to grow. This indicates that the hair follicle is still active and producing new hair. The rest period refers to a phase where the hair is not growing, but it is still attached to the hair follicle. Therefore, the correct answer states that after the resting phase, the hair is shed and a newer hair begins to grow, while during the rest period, the hair is still attached to the hair follicle but not growing.

    How long does the telogen stage last?

    • A.

      3-4 months

    • B.

      3-4 weeks

    • C.

      3-4 days

    Correct Answer
    A. 3-4 months
    Explanation
    The telogen stage refers to the resting phase of the hair growth cycle, during which the hair follicle is not actively producing hair. This stage typically lasts for several months, usually around 3-4 months. During this time, the old hair is shed and new hair begins to grow. Therefore, the correct answer is 3-4 months.

      30

    • D.

      90

    Correct Answer
    B. 10
    Explanation
    At any given time, approximately 10% of hair follicles are in the intermediate and shedding phases. This means that these follicles are either transitioning from the growth phase to the resting phase or are actively shedding hair. The remaining 90% of hair follicles are in the growth phase, where new hair is being produced.

    What seasons do you notice more hair loss due weather and daylight

    • A.

      Spring

    • B.

      Summer

    • C.

      Autumn

    • D.

      Winter

    Correct Answer(s)
    A. Spring
    C. Autumn
    Explanation
    During the spring and autumn seasons, there is a phenomenon called seasonal hair shedding, also known as telogen effluvium. This occurs due to changes in the hair growth cycle, where more hair follicles enter the resting (telogen) phase and eventually shed. The transition from winter to spring and summer to autumn involves changes in weather, temperature, and daylight hours, which can trigger this hair loss. Therefore, it is common to notice more hair loss during these seasons.

    There are some rare cases of individuals (both male and females) who lose all their hair regularly every seven years, as their hair growth cycle is not continuous. They remain virtually bald for about four months and then the hair regrows as normal

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Some individuals experience a unique hair growth cycle where they lose all their hair every seven years. This cycle is not continuous, meaning they remain bald for around four months before their hair starts to regrow normally. This phenomenon is rare but does occur in both males and females. Therefore, the statement is true.

    At what ages does hair grow the fastest?

    • A.

      1-5

    • B.

      16-30

    • C.

      5-10

    • D.

      10-25

    Correct Answer
    B. 16-30
    Explanation
    During the ages of 16-30, hair tends to grow the fastest. This is because during this time, the body is in its prime and the hair follicles are at their most active state. Hormonal changes and increased metabolism during this age range contribute to the rapid growth of hair. Additionally, the hair growth cycle is at its peak during these years, resulting in faster and healthier hair growth.

    What are the tiny muscles called that cause the hair to become erect?

    Correct Answer
    arrectores pilorum
    Explanation
    The tiny muscles that cause the hair to become erect are called arrectores pilorum. These muscles are attached to the hair follicles and contract in response to various stimuli such as cold or fear. When these muscles contract, they pull the hair follicles upright, causing the hair to stand on end. This phenomenon is commonly known as "goosebumps" or "piloerection."
