  2. Glenoid fossa - Wikipedia

    en.wikipedia.org/wiki/Glenoid_fossa

    The glenoid fossa of the scapula or the glenoid cavity is a bone part of the shoulder. The word glenoid is pronounced / ˈ ɡ l iː n ɔɪ d / or / ˈ ɡ l ɛ n ɔɪ d / (both are common) and is from Greek : gléne , "socket", reflecting the shoulder joint's ball-and-socket form. [ 1 ]

  3. Mandibular fossa - Wikipedia

    en.wikipedia.org/wiki/Mandibular_fossa

    In the temporal bone, the mandibular fossa is bounded anteriorly by the articular tubercle and posteriorly by the tympanic portion of the temporal bone, which separates it from the external acoustic meatus. The fossa is divided into two parts by a narrow slit, the petrotympanic fissure (Glaserian fissure).

  4. Shoulder girdle - Wikipedia

    en.wikipedia.org/wiki/Shoulder_girdle

    The glenohumeral joint is the articulation between the head of the humerus and the glenoid cavity of the scapula. It is a ball and socket type of synovial joint with three rotatory and three translatory degrees of freedom. The glenohumeral joint allows for adduction, abduction, medial and lateral rotation, flexion and extension of the arm.

  5. Shoulder joint - Wikipedia

    en.wikipedia.org/wiki/Shoulder_joint

    The rotator cuff muscles of the shoulder produce a high tensile force, and help to pull the head of the humerus into the glenoid cavity. The glenoid cavity is shallow and contains the glenoid labrum which deepens it and aids stability. With 120 degrees of unassisted flexion, the shoulder joint is the most mobile joint in the body.

  6. Glenoid labrum - Wikipedia

    en.wikipedia.org/wiki/Glenoid_labrum

    The glenoid labrum (glenoid ligament) is a fibrocartilaginous (but not fibrocartilage, as previously thought) structure attached around the rim of the glenoid cavity on the shoulder blade. The shoulder joint is considered a ball-and-socket joint .

  7. Fossa (anatomy) - Wikipedia

    en.wikipedia.org/wiki/Fossa_(anatomy)

    In anatomy, a fossa (/ ˈ f ɒ s ə /; [1] [2] pl.: fossae (/ ˈ f ɒ s iː / or / ˈ f ɒ s aɪ /); from Latin 'ditch, trench') is a depression or hollow, usually in a bone, such as the hypophyseal fossa (the depression in the sphenoid bone). [3]

  8. Glenoid tubercles - Wikipedia

    en.wikipedia.org/wiki/Glenoid_tubercles

    The glenoid tubercles are two small bony eminences (or tubercles) located above and below the glenoid cavity on the scapula. The glenoid tubercles consist of the supra-and the infraglenoid tubercle. The Latin terms supra and infra meaning above and below respectively refers to the tubercles location in relation to the glenoid cavity. The Latin ...

  9. Mandibular fracture - Wikipedia

    en.wikipedia.org/wiki/Mandibular_fracture

    Condylar fractures are classified by location compared to the capsule of ligaments that hold the temporomandibular joint (intracapsular or extracapsular), dislocation (whether or not the condylar head has come out of the socket (glenoid fossa) as the muscles (lateral pterygoid) tend to pull the condyle anterior and medial) and neck of the ...
