It acts as a barrier, allowing certain molecules to pass through while preventing others from entering or leaving the cell. This selective permeability is crucial for maintaining the internal environment of the cell and regulating the exchange of nutrients, waste products, and signaling molecules with the surrounding environment. The nucleus, on the other hand, contains the cell's genetic material and is involved in controlling cell functions, but it does not directly control the movement of substances in and out of the cell.

    In which layer of the skin, do cells become keritanised?

    • A.

      Stratum corneum

    • B.

      Stratum granulosum

    • C.

      Starum lucidium

    • D.

      Stratum germinativum

    Correct Answer
    B. Stratum granulosum
    Explanation
    The correct answer is Stratum granulosum. This is the layer of the skin where cells undergo the process of keratinization, which is the formation of the tough protein keratin. As cells move from the Stratum germinativum to the Stratum granulosum, they begin to produce keratin and other proteins, causing them to become flattened and filled with granules. These granules contain enzymes and lipids that help to waterproof the skin and provide protection against external factors.

    Which pathology is onychocryptosis?

    • A.

      Ingrowing toenail

    • B.

      Ringworm of the nail

    • C.

      White spots

    • D.

      Bacterial infection of the nail

    Correct Answer
    A. Ingrowing toenail
    Explanation
    Onychocryptosis refers to the condition of an ingrowing toenail, where the edge of the toenail grows into the surrounding skin, causing pain, inflammation, and sometimes infection. This condition commonly occurs in the big toe and can be caused by improper nail trimming, tight footwear, or genetic factors. It is important to treat ingrowing toenails promptly to prevent further complications and relieve discomfort.

    The tempro-mandibular joint is an example of which type of synovial joint?

    • A.

      Hinge

    • B.

      Ball and socket

    • C.

      Pivot

    • D.

      Condyloid

    Correct Answer
    D. Condyloid
    Explanation
    The tempro-mandibular joint refers to the joint connecting the temporal bone of the skull to the mandible (lower jaw). This joint allows for movement in multiple directions, including rotation, translation, and gliding. A condyloid joint is a type of synovial joint that allows for movement in two planes, making it the most suitable classification for the tempro-mandibular joint.

    Which lung has more lobes (3 instead of 2) and is therefore the largest?

    • A.

      Right

    • B.

      Left

    Correct Answer
    A. Right
    Explanation
    The right lung has three lobes instead of two, making it larger than the left lung. This anatomical difference allows for a greater surface area for gas exchange and increased respiratory capacity. The additional lobe in the right lung helps accommodate the heart, which is located slightly to the left side of the chest.

    What happens during inhalation?

    • A.

      Contraction of diaphragm muscle increases the volume of the thorax

    • B.

      Contraction of diaphragm muscle decreases the volume of the thorax

    Correct Answer
    A. Contraction of diapHragm muscle increases the volume of the thorax
    Explanation
    During inhalation, the diaphragm muscle contracts. This contraction causes the diaphragm to move downward, which increases the volume of the thorax. As the volume of the thorax increases, the pressure inside the lungs decreases. This decrease in pressure allows air to rush into the lungs, filling them with oxygen. Therefore, the correct answer is that the contraction of the diaphragm muscle increases the volume of the thorax.

    Which pigment inside of red blood cells picks up the oxygen?

    • A.

      Oxyhaemoglobin

    • B.

      Haemoglobin

    • C.

      Erythema

    • D.

      Plasma

    Correct Answer
    B. Haemoglobin
    Explanation
    Haemoglobin is the pigment inside red blood cells that picks up oxygen. It is a protein molecule that binds to oxygen in the lungs and carries it to the body's tissues and organs. This process is crucial for the transportation of oxygen throughout the body and is essential for normal bodily functions. Oxyhaemoglobin is the form of haemoglobin that is bound to oxygen, while erythema refers to the redness of the skin and plasma is the liquid component of blood.

    Which spinchter controls the movement of food from the stomach into the small intestine?

    • A.

      Cardiac

    • B.

      Pyloric

    Correct Answer
    B. Pyloric
    Explanation
    The pyloric sphincter controls the movement of food from the stomach into the small intestine. It is located at the lower end of the stomach and regulates the release of partially digested food, known as chyme, into the small intestine for further digestion and absorption. The pyloric sphincter opens and closes to allow the controlled passage of food, preventing backflow and ensuring proper digestion and absorption of nutrients.

      Trypsin

    • D.

      Amylase

    Correct Answer
    D. Amylase
    Explanation
    Amylase is the correct answer because it is an enzyme that is found in the mouth. It is responsible for breaking down carbohydrates into smaller molecules such as sugars. This enzyme is produced by the salivary glands and is released into the mouth during the process of chewing and swallowing food. Amylase starts the digestion of starches in the mouth before the food reaches the stomach.
