Phalanges and Upper Limb Anatomy

Anatomy of Phalanges

  • Phalanges: Bones of digits (fingers and toes).
  • Each digit named similarly based on its hand/foot location.
  • Terminology:
    • Singular: Phalanx
    • Plural: Phalanges

Structure of Digits

  • Thumb (1st digit):
    • Contains 2 phalanges (proximal & distal).
  • Fingers (2nd-5th digits):
    • Each contains 3 phalanges (proximal, middle, distal).

Naming Conventions

  • Proximal, Middle, Distal:
    • Digits are named based on their position:
    • Proximal phalanx of 1st digit
    • Middle phalanx of 2nd digit
    • Distal phalanx of 3rd digit
  • Thumb has no middle phalanx.

Reference for Quizzes and Study Materials

  • Lab Quiz:
    • Focus on facial and cranial bone markings, vertebrae, and upper limb bones (excluding upper limb markings).
  • Study Materials Provided:
    • Worksheets for practice and review on upper limb structures and articulations.
  • Important pages for reference: 197-209 from the textbook.

Study Recommendations

  • Spend time identifying individual bones and their articulations.
  • All bones in the upper limb (radius, ulna, carpals, metacarpals, phalanges) included in quizzes.

Additional Notes

  • Understand that the thumb is the 1st digit and all digits are numbered accordingly (1-5).
  • Encourage practice with practicals and hands-on learning using skeleton models for better understanding of anatomy.
