Which structure of the nervous system carries action potential in the direction of a synapse?

A. Cell body

B. Axon

C. Neuron

D. Myelin

Answer Explanation:

Axons carry action potential in the direction of synapses. Axons are the long, fiber-like structures that carry information from neurons. Electrical impulses travel along the body of the axons, some of which are up to a foot long.

A neuron is a type of cell that is responsible for sending information throughout the body. There are several types of neurons, including muscle neurons, which respond to instructions for movement; sensory neurons, which transmit information about the external world; and interneurons, which relay messages between neurons. Myelin is a fat that coats the nerves and ensures the accurate transmission of information in the nervous system.

Therefore, the Correct Answer is B.

  • Q #2: Which is NOT a type of protein?

    A. Fibrous

    B. Membrane

    C. Globular

    D. Unsaturated

    Answer Explanation

    There are three types of proteins: fibrous, membrane, and globular. Fibrous or structural proteins consist of collagen, elastin, and keratin. Membrane proteins are interactive and anchored to a membrane. Globular proteins consist of functional proteins like enzymes, hemoglobin, and insulin.

    Therefore unsaturated is the correct answer.

  • Q #3: Which of the following anatomical terms is NOT part of the knee?

    A. Medial collateral ligament

    B. Patella

    C. Lateral malleolus

    D. Lateral meniscus

    Answer Explanation

    The term "lateral malleolus" refers to the bony prominence on the outer side of the ankle.

    It is part of the ankle joint, not the knee joint. The other options, such as the medial collateral ligament, patella, and lateral meniscus, are all associated with the knee joint.
