metacarpal

Examples of metacarpal in the following topics:

• Carpals, Metacarpals, and Phalanges (The Hand)

  • The trapezium articulates with the scaphoid proximally and the first, thumb, and second metacarpal distally.
  • The trapezoid articulates with the scaphoid proximally and the second metacarpal distally.
  • The capitate articulates with the scaphoid and lunate proximally and the third and fourth metacarpal.
  • They are numbered moving lateral to medial, and start with the thumb, which is metacarpal I, and end with metacarpal V, the little finger.
  • The metacarpals connect the carpal bones of the wrist with the phalanges (finger bones).

• The Appendicular Skeleton

  • Hands (54 bones) - Left and right carpals (16) (wrist), metacarpals (10), proximal phalanges (10), intermediate phalanges (8) and distal phalanges (10)
  • The base of the hand contains eight bones (carpal bones), and the palm is formed by five bones (metacarpal bones).

• Overview of the Appendicular Skeleton

  • There are many constituents in the hand and wrist; the left and right carpals (16 bones in the wrist), Metacarpals (10 bones), Proximal phalanges (10 bones), Middle phalanges (eight bones), and Distal phalanges (10 bones).

• Congenital Defects

  • Examples of minor anomalies can include curvature of the 5th finger (clinodactyly), a third nipple, tiny indentations of the skin near the ears (preauricular pits), shortness of the 4th metacarpal or metatarsal bones, or dimples over the lower spine (sacral dimples).

• Types of Synovial Joints

  • The carpometacarpal or trapeziometacarpal joint of the thumb (between the metacarpal and carpal, the trapezium) and the sternoclavicular joint are examples of saddle joints.

• Dermatomyositis and Polymyositis

  • Discrete erythematous papules overlying the metacarpal and interphalangeal joints in a patient with juvenile dermatomyositis.
