Questions and Answers
  • 1. 

    Epithelial tissue is frequently damaged or lost by abrasion but has a ___________________

    Explanation
    Epithelial tissue is frequently subjected to damage or loss due to abrasion, such as from mechanical friction or injury. However, it possesses a high regeneration capacity, meaning it has the ability to repair and replace damaged or lost cells efficiently. This regenerative ability allows epithelial tissue to quickly restore its structure and function, ensuring the integrity and functionality of the organs and surfaces it covers.

    Continual replacement occurs through the divisions of the deepest epithelial cells near its base called _________________

    Explanation
    Continual replacement of cells in epithelial tissue occurs through the divisions of stem cells, which are located near the base of the tissue. Stem cells have the ability to divide and differentiate into specialized cells, allowing for the constant renewal and regeneration of the tissue. These stem cells give rise to daughter cells that can either remain as stem cells or differentiate into different cell types, contributing to the growth and maintenance of the epithelial tissue.

    These are continuously supplied into the nervous system.

    Explanation
    Touch, pressure, pain, and temperature are all sensory inputs that are continuously supplied into the nervous system. These sensations are detected by specialized receptors in the skin and other tissues, which then send signals to the brain through the nervous system. This allows us to perceive and respond to our environment, such as feeling the texture of an object, sensing pain or pressure, or detecting changes in temperature. These sensory inputs play a crucial role in our ability to interact with the world around us.

    ___________________ binds body structures together

    Explanation
    Connective tissue is a type of biological tissue that connects, supports, and binds together various body structures. It is composed of cells and an extracellular matrix, which contains fibers like collagen and elastin. Connective tissue provides structural support to organs and tissues, helps in the transportation of nutrients and waste products, and plays a crucial role in wound healing and immune response. Examples of connective tissue include tendons, ligaments, adipose tissue, and cartilage.

    ____________________ is highly variable in appearance, least specialized connective tissue in the body; loosely organized array of collagen and elastic fibers and abundant distribution of blood vessels; independent movements; found everywhere; surrounds nerves, blood vessels, and individual muscle cells; major component of the hypodermis.

    Explanation
    Loose connective tissue is highly variable in appearance and is the least specialized connective tissue in the body. It has a loosely organized array of collagen and elastic fibers, as well as an abundant distribution of blood vessels. It is found everywhere in the body and surrounds nerves, blood vessels, and individual muscle cells. It is also a major component of the hypodermis, which is the layer of tissue beneath the skin.

    _______________________ has collagen fibers packed tightly and aligned parallel to an applied force; resembles lasagna noodles stacked on each other; found in tendons and ligaments; few blood vessels(ie. takes a long time to heal[upper ear piercing]).

    Explanation
    Dense regular connective tissue is characterized by collagen fibers that are tightly packed and aligned parallel to an applied force. This arrangement gives the tissue strength and allows it to withstand tension in a specific direction. The comparison to lasagna noodles stacked on each other helps visualize the organization of the collagen fibers. This type of tissue is found in tendons and ligaments, which need to be strong and resistant to stretching. The limited presence of blood vessels in dense regular connective tissue contributes to its slow healing process, as seen in upper ear piercings.

    Bone is formed in cylindrical structures called _______.

    • A.

      Eggs

    • B.

      Osteons

    • C.

      Muscle Fibers

    • D.

      Pathogens

    Correct Answer
    B. Osteons
    Explanation
    Bone is formed in cylindrical structures called osteons. Osteons are the basic functional and structural units of compact bone. They consist of concentric layers of bone tissue called lamellae, which surround a central canal known as the Haversian canal. Osteons provide strength and support to the bone, as well as facilitate the passage of blood vessels and nerves through the bone tissue.
