    A cross bridge is formed when myosin heads bind to  

    • A.

      Troponin

    • B.

      Actin

    • C.

      Tropomyosin

    • D.

      Ca++

    • E.

      Ca-

    Correct Answer
    B. Actin
    Explanation
    A cross bridge is formed when myosin heads bind to actin. Actin is a protein that is part of the thin filaments in muscle fibers. When a muscle contracts, the myosin heads attach to the actin filaments and pull them closer together, causing the muscle to shorten. This binding of myosin to actin forms a cross bridge, which allows for the sliding of the thin and thick filaments, resulting in muscle contraction.

    A distinction between motor neurons and sensory neurons is that

    • A.

      Motor neurons send messages to the sensory receptor cells, whereas sensory neurons send messages from the sensory receptor cells.

    • B.

      Motor neurons send messages to muscles and glands in the peripheral nervous system, whereas sensory neurons send messages from the somatosensory cortex.

    • C.

      Motor neurons carry information away from the central nervous system, whereas sensory neurons carry information to the central nervous system.

    • D.

      Motor neurons connect to interneurons, whereas sensory neurons do not.

    Correct Answer
    C. Motor neurons carry information away from the central nervous system, whereas sensory neurons carry information to the central nervous system.
    Explanation
    Motor neurons and sensory neurons have different roles in the nervous system. Motor neurons carry information away from the central nervous system, transmitting signals from the brain and spinal cord to muscles and glands in the peripheral nervous system. On the other hand, sensory neurons carry information to the central nervous system, transmitting signals from sensory receptor cells (such as those in the skin, eyes, ears, etc.) to the brain and spinal cord for processing and interpretation. This distinction highlights the direction of information flow in these two types of neurons.

    • B.

      Second degree, partial thickness

    • C.

      Third degree, full thickness

    • D.

      First degree, full thickness

    Correct Answer
    C. Third degree, full thickness
    Explanation
    Third degree burns, also known as full thickness burns, affect all layers of the skin, including the epidermis, dermis, and subcutaneous tissue. These burns are characterized by the destruction of the skin and underlying tissues, resulting in a dry, leathery appearance. Nerve endings may be damaged, leading to a lack of pain sensation in the affected area. First and second degree burns do not penetrate as deeply and are typically associated with pain and blistering.

    Formed by Schwann cells in the PNS?

    • A.

      Nodes of Ranvier

    • B.

      Unmyelinated Axons

    • C.

      Dendrites

    • D.

      Myelin Sheath

    Correct Answer
    D. Myelin Sheath
    Explanation
    The myelin sheath is formed by Schwann cells in the peripheral nervous system (PNS). It is a protective covering that surrounds and insulates the axons of neurons, allowing for faster and more efficient transmission of electrical signals. The myelin sheath is essential for the proper functioning of the nervous system, as it helps to prevent signal loss and interference. The nodes of Ranvier, on the other hand, are small gaps in the myelin sheath where the axon is exposed. Unmyelinated axons do not have a myelin sheath at all. Dendrites, on the other hand, are the branch-like extensions of neurons that receive signals from other neurons.

    Information in neurons usually flows in what order?

    • A.

      Soma, dendrites, axon

    • B.

      Dendrites, soma, axon

    • C.

      Dendrites, myelin, axon terminals

    • D.

      Axon, soma, axon terminals

    Correct Answer
    B. Dendrites, soma, axon
    Explanation
    Neurons are specialized cells that transmit information in the form of electrical signals. The information typically flows in a specific order within a neuron. Dendrites are the branch-like structures that receive signals from other neurons and transmit them to the soma, which is the cell body of the neuron. The soma integrates these signals and generates an electrical impulse. This impulse then travels down the axon, a long fiber-like structure, which transmits the signal away from the soma. Therefore, the correct order of information flow in neurons is dendrites, soma, and then axon.

    Explanation
    Tendons are tough, fibrous connective tissues that connect muscles to bones. They play a crucial role in transmitting the force generated by the muscle to the bone, allowing movement to occur. This connection is necessary for the coordinated movement of the skeletal system, as the muscles contract and pull on the bones to generate movement. Therefore, the correct answer is "muscle to bone."

    The arrector pili muscle will stand up the hair on the skin when the skin is cold.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    The arrector pili muscle is a small muscle attached to the hair follicle. When the body is exposed to cold temperatures, the muscle contracts, causing the hair to stand up on the skin. This is commonly known as "goosebumps" or "piloerection." This physiological response helps to trap a layer of air near the skin, providing insulation and helping to keep the body warm. Therefore, the statement that the arrector pili muscle will stand up the hair on the skin when the skin is cold is true.
