Questions and Answers
  • 1. 

    What is the origin of FDP?

    Explanation
    The origin of FDP (Flexor Digitorum Profundus) is from both the ulna and the interosseus membrane. The FDP muscle originates from the medial epicondyle of the humerus, the coronoid process of the ulna, and the interosseus membrane. It then inserts into the distal phalanges of the four fingers. This muscle is responsible for flexing the fingers at the distal interphalangeal joints.

    What is the origin of FDS?

    • A.

      IOM

    • B.

      Radius

    • C.

      Ulna

    • D.

      Olecranon

    • E.

      CFO

    Correct Answer(s)
    B. Radius
    E. CFO
    Explanation
    The origin of FDS is the radius and CFO. The radius is one of the two bones in the forearm, and the FDS (Flexor Digitorum Superficialis) muscle originates from the radius bone. CFO stands for Chief Financial Officer, which is a corporate position responsible for managing the financial actions of a company. Therefore, the origin of FDS can be associated with both the anatomical structure of the radius bone and the professional role of a CFO.

      Olecranon

    • D.

      Coronoid

    Correct Answer
    A. CFO
    Explanation
    The correct answer is CFO. The question is asking about the origin of the Palmaris Longus muscle. CFO stands for the flexor carpi radialis, flexor carpi ulnaris, and palmaris longus, which are the three tendons that originate from the medial epicondyle of the humerus. Therefore, the Palmaris Longus muscle originates from the CFO.

    Correct Answer
    A. CFO
    Explanation
    The correct answer is CFO. CFO stands for Chief Financial Officer, which is a senior executive responsible for managing the financial actions of a company. The question is asking about the origin of FCR, but since FCR is not a commonly known acronym or abbreviation, it is likely that the question is referring to CFO as the correct answer.

    What is the insertion of FCU?

    • A.

      Hamate

    • B.

      Lunate

    • C.

      Pisiform

    • D.

      Base of 5th metacarpal

    • E.

      5th proximal phalanx

    Correct Answer(s)
    A. Hamate
    C. Pisiform
    D. Base of 5th metacarpal
    Explanation
    The insertion of the Flexor Carpi Ulnaris (FCU) muscle includes the hamate bone, pisiform bone, and the base of the 5th metacarpal bone. These structures provide attachment points for the FCU tendon, allowing it to exert its flexion and adduction functions on the wrist joint. The 5th proximal phalanx is not involved in the insertion of the FCU muscle.

    What is the insertion of FPL?

    • A.

      Proximal phalanx

    • B.

      Distal phalanx

    • C.

      Metacarpal

    Correct Answer
    B. Distal phalanx
    Explanation
    The insertion of FPL (Flexor Pollicis Longus) is the distal phalanx. This means that the tendon of the FPL muscle attaches to the bone at the tip of the thumb. The FPL muscle is responsible for flexing the thumb, allowing it to bend towards the palm.

    • D.

      Scaphoid, trapezium and retinaculum

    Correct Answer
    D. Scaphoid, trapezium and retinaculum
    Explanation
    The origin of flexor policis brevis is from the scaphoid, trapezium, and retinaculum.

    What is the origin or extensor pollicis longus?

    • A.

      Ulna and IOM

    • B.

      Radius and IOM

    • C.

      Scaphoid and trapezium

    • D.

      3rd and 4th metacarpal

    Correct Answer
    A. Ulna and IOM
    Explanation
    The extensor pollicis longus muscle originates from the ulna bone and the interosseous membrane (IOM). This muscle is responsible for extending the thumb, allowing it to move away from the palm. The ulna is one of the two bones in the forearm, while the IOM is a connective tissue that spans between the ulna and the radius bones. Therefore, the origin of the extensor pollicis longus muscle is the ulna and IOM.

    What is the origin of extensor pollicis brevis?

    • A.

      Radius and IOM

    • B.

      Ulna and IOM

    • C.

      Scaphoid and trapezium

    • D.

      3rd and 4th metacarpals

    Correct Answer
    A. Radius and IOM
    Explanation
    The extensor pollicis brevis muscle originates from the radius bone and the interosseous membrane (IOM). This muscle is located in the forearm and is responsible for extending the thumb. The radius is one of the two bones in the forearm, and the IOM is a fibrous structure that connects the radius and ulna bones. Therefore, the correct answer is "Radius and IOM."

    Correct Answer
    D. Ulna and IOM
    Explanation
    The origin of EDI is Ulna and IOM. This means that both the Ulna and IOM are involved in the development or creation of EDI. The Ulna is one of the two bones in the forearm, while IOM stands for Inter-Organizational Memorandum, which suggests that EDI originated from a collaborative effort between different organizations.
