Muscles Week 3

  1. What muscle lies on the anterior surface of forarm and has oblique fiber direction. Allows for pronation of forearm (spill the spoon)

    B) Pronator Teres
  2. This muscle is the prime mover of elbow extention

    C) Triceps brachi
  3. This muscle is an agttagonist to bicep brochii

    B) Triceps brachi
  4. Orgin:
    Long head - Infraglenoid tubercle of scapula
    Lateral head - Posterior surface of proximal 1/2 of humerus
    Medial head - posterior surface of distal 1/2 of humerus

    Olcranon process

    A) Triceps brachi
  5. This muscle is triangilar and weak elbow extensor?

    C) Anconeus
  6. This muscle asssit triceps brachii with elbow extention

    Orgin: Lateral epicondyle of humerus
    Insertion: Olecrenon process of ulna, superior 1/8 of ulna shaft

    D) Anconeus
  7. This muscle lies deep on anterior distal forarm near the wrist and pronates forearm

    C) Pronator Quadratus
  8. Name this muscle:

    Origin: Anterior distal 1/8 of unla shaft
    Insertion: Anterior distal 1/8 of radial shaft
    Action: Pronates the forearm

    C) Pronator Quadratus
  9. This muscle is antagonist to the pronator teres. It's located on the lateral side of the elbow and is deep to the forearm. 

    D) Supinator
  10. This muscle allows to "Carry the Soup"

    A) Supinator
  11. Name this muscle

    Lateral epicondyle of humerus
    Prox 1/8 of ulna shaft
    radial collateral ligament, annular ligament 

    Insertion: Prox Lateral radial shaft 
    Action: Supinates the forearm

    D) Flexor Carpi Ulnaris
  12. This muscle lies on anterior medial service of forearm

    Medial epicondyle of humerus
    medial olecranon
    Posterior proximal 2/3 of the ulna

    Insertion: base of metacarpal 5, pisiform and hamate
    Action: Flexes and adducts wrist, weak elbow flextion

    A) Flexor Carpi Ulnaris
  13. This muscle lies on the anterior, lateral surface of forearm.
    As a group, all of the flexors are more powerful than extendors

    D)  Flexor Carpi Radialis
  14. This muscle is on the medial epicondyle
    Insertion: base meta carpal 2 and 3
    Flexes and abducts wrist, flexes the elbow

    D)  Flexor Carpi Radialis
  15. This muscle is missing in 10% of the population

    C) Palma Longus
  16. This muscle flexes the wrist and elbow, tense the palmar aponeurosis. Creating the cupping of the hand.

    D) Palma Longus
  17. This muscle

    medial epocondyle of humerus
    proximal radial shaft 
    cronoid process of ulna

    Insertion: middle phalanges of digits 2-5

    Action: Flexes wrist, flexes fingers at PIP, and MP joints

    C) Flexor Digitorum Superficialis
  18. This muscle lies deep to superficialis

    Origin: Anterior proximal 3/4 of ulna shaft
    Insertion: Distal Phalanges of digits 2-5
    Action: Flexis fingers at PIP, and MP joint and DIP joint

    • B)  Flexor digitorum Profundus
