  • 2. 

    What are the three parts of a neuron?

    • Nucleus, Axons and Pons

    • Nucleus, Dendrites and Pons

    • Nucleus, Dendrites and Axons

    Correct Answer
    A. Nucleus, Dendrites and Axons
    Explanation
    The three parts of a neuron are the nucleus, dendrites, and axons. The nucleus is the central part of the cell that contains genetic material. Dendrites are the branch-like extensions that receive signals from other neurons and transmit them to the cell body. Axons are long, slender extensions that transmit signals away from the cell body to other neurons or target cells.

  • 3. 

    Nerve cells are called __________.

    • Impulses

    • Neurons

    • Enzymes

    Correct Answer
    A. Neurons
    Explanation
    Nerve cells are called neurons. Neurons are specialized cells that transmit information through electrical and chemical signals in the nervous system. They play a crucial role in the communication and coordination of different parts of the body, allowing us to perceive and respond to stimuli. Neurons have a unique structure with dendrites that receive signals, an axon that transmits signals, and synapses that allow communication with other neurons or target cells. Therefore, the correct answer is neurons.

    What are the two main parts of the nervous system?

    • Central Nervous System and Peripheral Nervous System

    • Somatic Nervous System and Autonomic Nervous System

    • Somatic Nervous System and Central Nervous System

    Correct Answer
    A. Central Nervous System and Peripheral Nervous System
    Explanation
    The nervous system is divided into two main parts: the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS consists of the brain and spinal cord, which are the control centers of the body. The PNS includes all the nerves outside of the CNS, which connect the CNS to the rest of the body. This division allows for the coordination and communication between different parts of the body, ensuring proper functioning and response to stimuli. The other options mentioned, somatic nervous system and autonomic nervous system, are subdivisions of the PNS and are not the main parts of the nervous system.

    It is in charge of body processes that happen slowly, such as cell growth.

    • Nervous System

    • Endocrine System

    • Digestive System

    Correct Answer
    A. Endocrine System
    Explanation
    The endocrine system is responsible for regulating and controlling various body processes that occur slowly, such as cell growth. It does this by producing and releasing hormones into the bloodstream, which then travel to target cells or organs to initiate specific actions. Unlike the nervous system, which primarily controls rapid responses, the endocrine system works more gradually and helps maintain homeostasis in the body. The digestive system is not involved in regulating cell growth or other slow body processes.

    What are the two major parts of the Peripheral Nervous System?

    • Central Nervous System and Peripheral Nervous System

    • Somatic Nervous System and Autonomic Nervous System

    • Somatic Nervous System and Central Nervous System

    Correct Answer
    A. Somatic Nervous System and Autonomic Nervous System
    Explanation
    The correct answer is Somatic Nervous System and Autonomic Nervous System. The peripheral nervous system consists of two major parts: the somatic nervous system and the autonomic nervous system. The somatic nervous system controls voluntary movements and transmits sensory information to the central nervous system. The autonomic nervous system regulates involuntary bodily functions, such as heart rate, digestion, and breathing. Therefore, these two parts together make up the peripheral nervous system.

  • 7. 

    What are the neurons that take the messages from the senses to the brain?

    • Motor Neurons

    • Sensory Neurons

    • Medulla Oblongata

    Correct Answer
    A. Sensory Neurons
    Explanation
    Sensory neurons are responsible for transmitting messages from the senses to the brain. These specialized neurons are located in the sensory organs such as the eyes, ears, nose, tongue, and skin. They detect various stimuli such as light, sound, smell, taste, and touch, and convert them into electrical signals that can be understood by the brain. The sensory neurons then transmit these signals to the brain, allowing us to perceive and interpret the information from our environment.

    Rate this question:

  • 8. 

    It is a thick bunch of nerves that start at the brain stem and go down the back. It is protected by the spinal column.

    • Spinal Cord

    • Pons

    • Pituitary Gland

    Correct Answer
    A. Spinal Cord
    Explanation
    The given description states that it is a thick bunch of nerves that start at the brain stem and go down the back, and it is protected by the spinal column. This perfectly matches the characteristics of the spinal cord, which is a long, cylindrical structure made up of nerve fibers that transmit signals between the brain and the rest of the body. The spinal cord is indeed protected by the spinal column, making it the correct answer.

    Rate this question:

  • 9. 

    Nerve cells send messages in the form of electrical signals called __________.

    • Impulses

    • Neurons

    • Enzymes

    Correct Answer
    A. Impulses
    Explanation
    Nerve cells, also known as neurons, communicate with each other by sending electrical signals called impulses. These impulses travel along the length of the neuron, allowing for the transmission of information throughout the nervous system. Neurons are specialized cells that are capable of generating and transmitting these impulses, which play a crucial role in the functioning of the nervous system and the communication between different parts of the body. Enzymes, on the other hand, are not directly involved in the transmission of electrical signals in nerve cells.

  • 10. 

    What are chemical messengers that transfer information and instructions from one set of cells to another?

    • Organs

    • Hormones

    • Glands

    Correct Answer
    A. Hormones
    Explanation
    Hormones are chemical messengers that transfer information and instructions from one set of cells to another. They are produced by various glands in the body and are released into the bloodstream, where they travel to target cells or organs to regulate various bodily functions. Hormones play a crucial role in maintaining homeostasis, growth, development, and reproduction.

  • 11. 

    What are the neurons that carry instructions from the brain to the body and what action to take?

    • Motor Neurons

    • Sensory Neurons

    • Medulla Oblongata

    Correct Answer
    A. Motor Neurons
    Explanation
    Motor neurons are the neurons that carry instructions from the brain to the body and determine what action to take. They transmit signals from the central nervous system to the muscles, allowing for voluntary movements and controlling bodily functions. Motor neurons play a crucial role in coordinating movement, allowing us to perform tasks such as walking, talking, and grasping objects.

    Rate this question:

  • 12. 

    Which is the cell body of a neuron?

    • Nucleus

    • Dendrites

    • Axons

    Correct Answer
    A. Nucleus
    Explanation
    The cell body of a neuron, also known as the soma, contains the nucleus. The nucleus is responsible for controlling the functions of the cell and contains the genetic material of the neuron. It plays a crucial role in maintaining the overall health and functioning of the neuron by regulating the synthesis of proteins and other important molecules. The dendrites and axons, on the other hand, are extensions of the cell body that transmit signals to and from other neurons.

    Rate this question:

  • 13. 

    What is a group of cells that produces and secretes or gives off chemicals?

    • Gland

    • Hormones

    • Organs

    Correct Answer
    A. Gland
    Explanation
    A gland is a group of cells that produces and secretes or gives off chemicals. Glands are responsible for producing various substances such as hormones, enzymes, and sweat. They play a crucial role in regulating bodily functions and maintaining homeostasis. Glands can be classified as exocrine or endocrine, depending on whether they release their secretions into ducts or directly into the bloodstream. This explanation aligns with the answer choice "Gland."
