Upper appendicular

Test Preparation Overview

  • Testing Format:

    • Arrive and set belongings at the front of the room.

    • Bring only a pen or pencil.

    • 29 stations available around lab tables for testing.

    • Answer sheets provided; work at your own pace.

    • Class is small, reducing wait time.

    • Ample additional lab time post-test for study or questions.

  • Test Conduct Guidelines:

    • Avoid peeking at others’ papers or crowding around stations.

    • Maintain respect and patience while waiting.

Anatomy of the Upper Limb

  • Key Bones:

    • Scapula (Shoulder Blade):

      • Major features:

        • Spine: A ridge protruding from posterior surface.

        • Glenoid cavity: A shallow bowl where the head of the humerus connects, leading to high shoulder mobility but potential for dislocation.

  • Humerus:

    • Head of Humerus: Round top that fits in the glenoid cavity.

    • Greater tubercle: A notable bump on top of the humerus near the head.

    • Distal End Features:

      • Epicondyles: Bumps on either side near the elbow (medial epicondyle protrudes more than the lateral).

  • Forearm Bones:

    • Radius:

      • Rotates around the ulna during hand movements (thumb follows the radius).

    • Ulna:

      • Contains a scoop shape (olecranon) at the elbow end.

  • Wrist Bones:

    • Individual bones are acknowledged, but memorizing all names is not required for the class.

    • Phalanges (Fingers): Each finger has three phalanx bones, except the thumb, which has only two (proximal and distal).

Important Terms and Concepts

  • Fossa: A groove in the bone; e.g., supraspinous fossa (groove above the spine). Understanding terms helps in identifying locations on the bones.

  • Rotator Cuff: Four muscles stabilizing the shoulder joint, essential for shoulder movement.

  • Distal vs Proximal: Indicates positions on limbs; distal is further from the center, proximal is closer.

Study Recommendations

  • Use available lab time to practice handling bones and reviewing anatomical models.

  • Make mental or physical notes of key relationships (e.g., which bone follows which thumb during movements).

  • Use practice quizzes and study aids, utilizing histology slides and models as necessary.

  • If confused, ask the instructor for clarification on anatomical features or terms.

Additional Notes

  • Connection of bone anatomy to muscle identification can simplify learning.

  • Use mnemonic devices or personal associations to remember bone names and locations.

  • Familiarity with anatomical positions enhances understanding and identification during practical applications in lab settings.
