Muscle And Nervous Tissue Quiz - Quiz

Just like most of the other parts of the body, body muscles are controlled and directed by the nervous tissue, which regulates and controls muscle actions. How much do you know about the subject? Take the quiz and find out.


Questions and Answers
  • 1. 

    What is this?

    Explanation
    The given answer "cell body" is the correct answer to the question "What is this?" The term "cell body" refers to the main part of a cell, also known as the soma. It contains the nucleus and other organelles necessary for the cell's function. In the context of biology or anatomy, when asked "What is this?" and given the term "cell body," it indicates that the question is referring to the main part of a cell.

    What type of tissue is this?

    Explanation
    This tissue is smooth muscle tissue because it lacks striations and is involuntary. Smooth muscle tissue is found in the walls of hollow organs, such as the intestines and blood vessels, and is responsible for their contraction and relaxation. It is composed of spindle-shaped cells that are uninucleated and have a central nucleus.

    What type of tissue is this?

    Explanation
    The tissue shown in the question is cardiac muscle tissue. Cardiac muscle tissue is a specialized type of muscle tissue found only in the heart. It is responsible for the contraction and relaxation of the heart, allowing it to pump blood throughout the body. Cardiac muscle tissue is striated and involuntary, meaning it is under unconscious control. It contains intercalated discs, which allow for synchronized contractions of the heart muscle cells. Overall, the presence of striations, branching fibers, and intercalated discs in the image suggests that it is cardiac muscle tissue.

    What is this?

    Explanation
    A dendrite is a part of a neuron that receives signals from other neurons and carries them towards the cell body. It is responsible for transmitting information to the neuron, allowing it to process and respond to stimuli. Dendrites have a tree-like structure with numerous branches, which increase the surface area available for receiving signals. This enables efficient communication between neurons and plays a crucial role in the functioning of the nervous system.

    What is this?

    Explanation
    Neuroglia refers to a type of cells that provide support and protection to neurons in the nervous system. They are non-neuronal cells that make up the majority of cells in the brain and spinal cord. Neuroglia cells perform various functions such as insulating neurons, regulating the chemical environment, and repairing damaged tissue. They play a crucial role in maintaining the overall health and functioning of the nervous system.

  • 7. 

    What type of tissue is this?

    Explanation
    The given correct answer is "Skeletal muscle tissue." This type of tissue is responsible for the voluntary movement of the body. It is attached to the skeleton and is composed of long, cylindrical cells called muscle fibers. Skeletal muscle tissue is striated, meaning it has a striped appearance under a microscope. It is also multinucleated, meaning it contains multiple nuclei within each muscle fiber. Skeletal muscle tissue is under conscious control and is responsible for actions such as walking, running, and lifting weights.

  • 8. 

    What type of tissue is this?

    Explanation
    The given correct answer is "Nervous tissue." Nervous tissue is a type of tissue that is found in the nervous system, including the brain, spinal cord, and nerves. It is made up of specialized cells called neurons that transmit electrical signals and support cells called glial cells. Nervous tissue is responsible for coordinating and transmitting information throughout the body, allowing for the control of bodily functions and the processing of sensory information.

  • 9. 

    What is this?

    Explanation
    A neuron is a specialized cell in the nervous system that transmits information through electrical and chemical signals. It is the basic building block of the nervous system and plays a crucial role in functions such as perception, cognition, and movement. Neurons have a unique structure with dendrites that receive signals, a cell body that processes information, and an axon that transmits signals to other neurons or effector cells. This explanation provides a definition and overview of what a neuron is without explicitly stating that it is the correct answer.

  • 10. 

    What is this?

    Explanation
    An intercalated disc is a specialized junction between cardiac muscle cells. It contains gap junctions, which allow for rapid electrical communication between cells, and desmosomes, which provide mechanical strength to the tissue. This structure is crucial for coordinating the contraction of the heart, ensuring that it acts as a single functional unit.

    Rate this question:

  • 11. 

    What are these called?

    Explanation
    Striations are the term used to describe a series of parallel lines or grooves that are visible on a surface. These lines or grooves can be found in various contexts, such as on rocks, muscles, or even in fingerprints. The term "striations" accurately describes this characteristic, making it the correct answer for the question.
