Questions and Answers
  • 1. 

    At which joint do the femur and coxal bone meet?

    • A.

      Hip

    • B.

      Knee

    • C.

      Ankle

    • D.

      Wrist

    Correct Answer
    A. Hip
    Explanation
    The femur and coxal bone meet at the hip joint. This joint is a ball-and-socket joint, allowing for a wide range of motion in the hip area. The femur, or thigh bone, fits into the socket of the coxal bone, which is part of the pelvis. The hip joint is responsible for connecting the lower body to the upper body and plays a crucial role in walking, running, and other movements involving the legs.

    At which joint do the scapula and humerus meet?

    • A.

      Hip

    • B.

      Wrist

    • C.

      Shoulder

    • D.

      Elbow

    Correct Answer
    C. Shoulder
    Explanation
    The scapula and humerus meet at the shoulder joint. The shoulder joint is a ball-and-socket joint that allows for a wide range of motion in the arm. It is formed by the articulation of the head of the humerus with the glenoid cavity of the scapula. This joint is responsible for movements such as flexion, extension, abduction, adduction, and rotation of the arm. The hip joint, wrist joint, and elbow joint are not correct answers as they are different joints where the scapula and humerus do not meet.

    Injury to the epiphyseal disc may

    • A.

      Stunt the growth of the injured leg

    • B.

      Stimulate the bone to become cancerous

    • C.

      Inhibit blood cell formation

    • D.

      Cause paralysis

    Correct Answer
    A. Stunt the growth of the injured leg
    Explanation
    Injury to the epiphyseal disc may stunt the growth of the injured leg because the epiphyseal disc is responsible for bone growth in length. If the disc is injured, it can disrupt the normal process of bone growth, leading to a shorter or stunted leg.

    Rate this question:

  • 4. 

    Which bone structure is most concerned with hematopoiesis?

    • A.

      Diaphysis

    • B.

      Bone marrow

    • C.

      Articular cartilage

    • D.

      Epiphyseal disc

    Correct Answer
    B. Bone marrow
    Explanation
    The bone marrow is the correct answer because it is the site where hematopoiesis, the process of blood cell formation, occurs. Hematopoiesis involves the production of red blood cells, white blood cells, and platelets, which are essential for the functioning of the immune system and blood clotting. The bone marrow contains stem cells that differentiate into these blood cells, making it the primary location for hematopoiesis in the body.

  • 5. 

    Which of the following refers to an exaggerated thoracic curvature of the spine (hunchback)?

    • A.

      Kyphosis

    • B.

      Osteoporosis

    • C.

      Scoliosis

    • D.

      Lordosis

    Correct Answer
    A. Kyphosis
    Explanation
    Kyphosis refers to an exaggerated thoracic curvature of the spine, commonly known as hunchback. This condition causes the upper back to appear rounded and can lead to a stooped posture. Kyphosis can be caused by various factors, including poor posture, osteoporosis, spinal fractures, or certain medical conditions. Treatment options depend on the severity and underlying cause of kyphosis and may include physical therapy, bracing, pain management, or in severe cases, surgery.

  • 6. 

    What is the outer lining of connective tissue that surrounds the diaphysis of a long bone and contains the blood vessels that supply the bone?

    • A.

      Periosteum

    • B.

      Endosteum

    • C.

      Osteon

    • D.

      Canaliculi

    Correct Answer
    A. Periosteum
    Explanation
    The periosteum is the outer lining of connective tissue that surrounds the diaphysis of a long bone. It contains the blood vessels that supply the bone, providing essential nutrients and oxygen for bone growth and repair. The periosteum also plays a role in bone formation and repair by providing a surface for the attachment of tendons and ligaments. It acts as a protective layer for the bone and helps in the healing process of fractures and other bone injuries.

    Rate this question:

  • 7. 

    Which of the following is true at acetabulum?

    • A.

      Recieves the head of the femur

    • B.

      It is the crest part of the iliac crest

    • C.

      It is located anterior to the symphysis pubis

    • D.

      It is a depression of the scapula

    Correct Answer
    A. Recieves the head of the femur
    Explanation
    The acetabulum is a socket-like structure located in the pelvis. It is responsible for receiving and holding the head of the femur, forming the hip joint. The other options mentioned in the question are incorrect. The iliac crest is a ridge on the top of the hip bone, not a part of the acetabulum. The acetabulum is not located anterior to the symphysis pubis, but rather posterior to it. Lastly, the acetabulum is not a depression of the scapula, but rather a part of the pelvis.

  • 8. 

    The olecranon process is most associated with this joint

    • A.

      The hip

    • B.

      The elbow

    • C.

      The wrist

    • D.

      A ball and socket joint

    Correct Answer
    B. The elbow
    Explanation
    The olecranon process is a bony prominence located at the upper end of the ulna bone in the forearm. It forms the bony tip of the elbow and serves as an attachment point for muscles and ligaments. Therefore, the olecranon process is most associated with the elbow joint.

    Which of the following best describes the flexion of the finger?

    • A.

      Hinge joint

    • B.

      Abduction

    • C.

      Suture

    • D.

      Fontanelle

    Correct Answer
    A. Hinge joint
    Explanation
    The flexion of the finger refers to the bending movement that occurs at the joint between the bones of the finger. This movement is best described as a hinge joint, as it allows the finger to bend and straighten in a manner similar to the opening and closing of a door on its hinges. The hinge joint provides stability and allows for a wide range of motion in the finger, making it the most suitable description for the flexion of the finger.

    • C.

      Glenoid cavity

    • D.

      Obturator foramen

    Correct Answer
    D. Obturator foramen
    Explanation
    The obturator foramen is the large opening in the coxal bone. It is located in the inferior part of the bone, between the pubis and ischium. This foramen allows for the passage of blood vessels, nerves, and the obturator nerve. It is an important anatomical feature of the coxal bone that contributes to the overall structure and function of the pelvis.

    • C.

      Coccyx

    • D.

      Femur

    Correct Answer
    D. Femur
    Explanation
    The greater and lesser trochanters are bony projections located on the femur bone. The femur is the longest and strongest bone in the human body, and it forms the upper part of the leg. The trochanters serve as attachment points for muscles and ligaments, providing stability and facilitating movement at the hip joint. The tibia and fibula are bones in the lower leg, while the coccyx is a small bone at the base of the spine.

    Rate this question:

  • 13. 

    What is the type of projection that articulates with the glenoid cavity?

    • A.

      Crest

    • C.

      Spine

    • D.

      Head

    Correct Answer
    A. Crest
    Explanation
    The type of projection that articulates with the glenoid cavity is the crest. The glenoid cavity is a shallow depression in the scapula bone of the shoulder, and the crest is a ridge-like projection on a bone. The crest of the scapula articulates with the glenoid cavity, allowing for movement and stability in the shoulder joint.

    What is the term that refers to the replacement of cartilage by bone?

    • A.

      Osteoporosis

    • B.

      Osteomalacia

    • C.

      Ossification

    • D.

      Diarthrosis

    Correct Answer
    C. Ossification
    Explanation
    Ossification is the term that refers to the replacement of cartilage by bone. This process occurs during bone development and growth, where cartilage is gradually replaced by bone tissue. Ossification is essential for the formation and strengthening of the skeletal system. Osteoporosis refers to the loss of bone density, while osteomalacia is the softening of bones. Diarthrosis is a term used to describe a type of joint in the body.

    Which of the following is true of ilium, ischium, and pubis?

    • A.

      They are part of the appendicular skeleton

    • B.

      They are processes located in the femur

    • C.

      They are muscles that attach to the femur

    • D.

      They form the coxal bone

    Correct Answer
    D. They form the coxal bone
    Explanation
    The ilium, ischium, and pubis are three separate bones that come together to form the coxal bone, also known as the hip bone. These three bones are located in the pelvic region and are part of the appendicular skeleton, which includes the bones of the limbs and the girdles that attach them to the axial skeleton. They are not processes located in the femur, nor are they muscles that attach to the femur. Instead, they are distinct bones that join together to form the coxal bone.

  • 16. 

    What is the classification of the intervertebral discs and the symphysis pubis?

    • A.

      Synovial

    • B.

      Sutures

    • C.

      Diarthrotic

    • D.

      Amphiarthrotic

    Correct Answer
    A. Synovial
    Explanation
    The intervertebral discs and the symphysis pubis are classified as synovial joints. Synovial joints are characterized by the presence of a synovial fluid-filled cavity between the articulating surfaces, allowing for a wide range of movement. These joints are found in the limbs and allow for movements such as flexion, extension, rotation, and abduction. The intervertebral discs are located between the vertebrae, while the symphysis pubis is the joint between the two pubic bones in the pelvis. Both of these joints exhibit the characteristics of synovial joints, making synovial the correct classification.

    Rate this question:

  • 17. 

    Which of the following is true of synovial or diarthrotic joints

    • A.

      They are freely movable

    • B.

      They are sutures

    • C.

      They are found only in the lower extremeties

    • D.

      They are found only within the vertebral column and the symphysis pubis

    Correct Answer
    A. They are freely movable
    Explanation
    Synovial or diarthrotic joints are characterized by their ability to be freely movable. Unlike sutures, which are immovable joints found in the skull, synovial joints allow for a wide range of motion. These joints can be found throughout the body, not just in the lower extremities or within specific areas like the vertebral column and the symphysis pubis. Therefore, the statement "they are freely movable" accurately describes synovial or diarthrotic joints.

    What is the name of the "soft spots" in a baby's skull?

    • A.

      Sinus

    • B.

      Fontanelles

    • C.

      Diarthrotic joints

    • D.

      Sutures

    Correct Answer
    B. Fontanelles
    Explanation
    Fontanelles, also known as "soft spots," are the gaps between the bones in a baby's skull. These areas are covered by a tough membrane and allow for the growth and expansion of the skull as the baby's brain develops. Fontanelles are important for the delivery process, as they allow the skull to compress and pass through the birth canal. Over time, these soft spots gradually close as the bones of the skull fuse together.

    • D.

      Bones of the vertebral column:atlas, axis, coxal bone

    Correct Answer
    D. Bones of the vertebral column:atlas, axis, coxal bone
    Explanation
    The group "bones of the vertebral column: atlas, axis, coxal bone" is incorrect. The atlas and axis are actually the first two vertebrae in the neck, while the coxal bone is part of the pelvic girdle. The correct group should include the vertebrae of the vertebral column, such as cervical, thoracic, lumbar, and sacral bones.
