    Directions and Postions __________ pertains to a structure closer to the midline of the body.

    • Posterior

    • Medial

    • Promixal

    • Anterior

    Correct Answer
    A. Medial
    Explanation
    The term "medial" refers to a structure that is closer to the midline of the body. In anatomical terms, the midline is an imaginary line that divides the body into left and right halves. Therefore, a structure that is described as medial is located towards the midline, while a structure that is described as lateral is located away from the midline. In this case, "medial" is the correct answer because it best describes a structure closer to the midline of the body.

    Rate this question:

  • 3. 

    Directions and Postions __________ refers to a structure further away from the midline.

    • Superficial

    • Lateral

    • Anterior

    • Medial

    Correct Answer
    A. Lateral
    Explanation
    Lateral refers to a structure that is further away from the midline. In anatomical terms, the midline is an imaginary line that divides the body into left and right halves. When something is described as lateral, it means it is located towards the side or away from the midline. Therefore, in this case, the correct answer is lateral.

    Rate this question:

  • 4. 

    Movements of the Body ___________ moves a limb laterally away from the midline.

    • Flexion

    • Extension

    • Abduction

    • Rotation

    Correct Answer
    A. Abduction
    Explanation
    Abduction refers to the movement of a limb away from the midline of the body. This means that the limb is moved laterally, or towards the side, away from the center of the body. Flexion refers to the bending of a joint, extension refers to the straightening of a joint, and rotation refers to the movement of a body part around its axis. Therefore, the correct answer is abduction as it specifically describes the movement of a limb away from the midline.

    • Medial

    • Lateral

    • Posterior

    • Anterior

    Correct Answer
    A. Posterior
    Explanation
    Posterior pertains to a structure further toward the back of the body than another structure. It refers to the direction or position that is opposite to the anterior side. In anatomical terms, posterior is used to describe structures that are located towards the back of the body or further away from the front.

    Rate this question:

  • 11. 

    Planes of Movement Which plane divides the body into left and right halves?

    • Frontal Plane

    • Sagittal Plane

    • Transverse Plane

    Correct Answer
    A. Sagittal Plane
    Explanation
    The sagittal plane is the plane that divides the body into left and right halves. This plane runs vertically and divides the body into two equal halves, with one side being the mirror image of the other. It is named after the sagittal suture of the skull, which lies in this plane. The frontal plane divides the body into front and back halves, while the transverse plane divides it into upper and lower halves.

    Rate this question:

  • 12. 

    Movements of the Body ____________ is movement that straightens or opens a joint.

    • Flexion

    • Adduction

    • Medial Rotation

    • Extension

    Correct Answer
    A. Extension
    Explanation
    Extension is the movement that straightens or opens a joint. When a joint is extended, the angle between the bones increases, allowing for the joint to move into a more straightened position. This movement is commonly seen in activities such as kicking a ball or straightening the arm or leg. Flexion, on the other hand, is the opposite movement, where the joint angle decreases. Adduction refers to movement towards the midline of the body, and medial rotation involves inward rotation of a limb or body part.

    The Cardiovascular System  _________ carry the blood back to the heart.

    • Arterioles

    • Arteries

    • Capillaries

    • Veins

    Correct Answer
    A. Veins
    Explanation
    Veins carry the blood back to the heart. Unlike arteries, which carry oxygenated blood away from the heart to the rest of the body, veins carry deoxygenated blood from the body's tissues back to the heart. Veins have thinner walls and contain valves to prevent the backward flow of blood. This allows the blood to flow efficiently against gravity and return to the heart, where it can be reoxygenated and pumped out to the body again.

    Types of Joints Which joint is usually between two flat surfaces and allows the least movement of all synovial joints?

    • Ball-and-socket

    • Gliding

    • Saddle

    • Pivot

    Correct Answer
    A. Gliding
    Explanation
    A gliding joint is usually between two flat surfaces and allows the least movement of all synovial joints. This type of joint allows bones to slide past each other in various directions, but the movement is limited. Unlike ball-and-socket or saddle joints, which allow for a wider range of movement, a gliding joint only permits small, sliding motions. Similarly, a pivot joint allows for rotation around a central axis, while a gliding joint primarily facilitates sliding movements.

    The Cardiovascular System   The _________ carry blood away from the heart.

    • Arteries

    • Capillaries

    • Veins

    • Arterioles

    Correct Answer
    A. Arteries
    Explanation
    Arteries are the blood vessels that carry oxygenated blood away from the heart to various parts of the body. They have thick, elastic walls that help maintain blood pressure and allow for efficient blood flow. Arteries branch out into smaller blood vessels called arterioles, which further distribute the blood to the capillaries. Capillaries are the smallest blood vessels where oxygen and nutrients are exchanged with tissues. Veins, on the other hand, carry deoxygenated blood back to the heart. Therefore, the correct answer is arteries.
