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.

  • Homologous Structures

    • The third metacarpal is shaded throughout; the shoulder is crossed-hatched.

  • Types of Synovial Joints

    • (c) The articulation between the trapezium carpal bone and the first metacarpal bone at the base of the thumb is a saddle joint.
