Each finger and thumb are called
Digits
Each digit consist of two or three separate bones called
Phalanges.

Proximal and distal.
Each metacarpal is composed of three parts:
Head, body and base
Interphalangeal joint is.

Metacarpophalangeal (mcp) joint
Joint between first metacarpal and proximal phalanx
Dip
Distal interphalangeal joint
Pip
Proximal interphalangeal joint
Most proximally
M.c.p (metacarpo-phalangeal)
