This metacarpal corresponds to the Pollux.
Answer: What is Metacarpal I?
This joint is formed by the articulation between the radius and proximal row carpals.
Answer: What is the Radiocarpal Joint?
This crescent-shaped carpal bone articulates with the radius at the radiocarpal joint.
Answer: What is the Lunate?
This joint in the thumb connects only two phalanges and is analogous to the big toe joint.
Answer: What is the Interphalangeal (IP) Joint of the Thumb?
This styloid process is larger distally and located on the lateral side of the forearm.
Answer: What is the Radial Styloid?
This proximal row bone is named for its triangular, three-cornered shape.
Answer: What is the Triquetral?
This carpal bone is located on the thumb side and is known as the “little table.”
Answer: What is the Trapezium?
This styloid process is smaller distally and located medially.
Answer: What is the Ulnar Styloid?
Using “Some Lovers Try Positions…,” this is the first bone listed laterally in the proximal row.
Answer: What is the Scaphoid?
This joint connects distal row carpals with metacarpals 1–5.
Answer: What are the Carpometacarpal (CMC) Joints?
This small, pea-shaped bone sits anteriorly and is often palpated on the medial side of the wrist.
Answer: What is the Pisiform?
These three anatomical regions make up each metacarpal.
Answer: What are the Base, Body, and Head?
This joint connects the proximal and distal rows of carpal bones.
Answer: What is the Midcarpal Joint?
This centrally located carpal bone is considered the “head” of the wrist.
Answer: What is the Capitate?
This joint distributes forces across the radius and ulna at the distal forearm.
Answer: What is the Distal Radioulnar Joint?
In lateral-to-medial order, this bone is the final bone of the proximal row.
Answer: What is the Pisiform?
This digit is unique because it lacks a middle (intermediate) phalanx.
Answer: What is the Thumb?
This distal row bone contains a hook-like projection on its palmar surface.
Answer: What is the Hamate?
This type of joint connects proximal and intermediate phalanges in digits 2–5.
Answer: What are the Proximal Interphalangeal (PIP) Joints?
This joint involves articulation between metacarpals and proximal phalanges.
Answer: What are the Metacarpophalangeal (MCP) Joints?
This joint connects intermediate and distal phalanges in digits 2–5.
Answer: What are the Distal Interphalangeal (DIP) Joints?
These bones are divided into proximal, middle, and distal segments (except one digit).
Answer: What are the Phalanges?
