- Trapezium: a rounded-square shaped bone above the scaphoid and under the thumb.
- Trapezoid: bone beside the trapezium that’s shaped like a wedge.
What are phalanges?
Phalanges. The 14 bones that are found in the fingers of each hand and also in the toes of each foot. Each finger has 3 phalanges (the distal, middle, and proximal); the thumb only has 2. Metacarpal bones.
What are the tendons in the hand called?
The tendons on the palm side bend the fingers. These are known as the flexor tendons. When you bend or straighten your finger, the flexor tendons slide through snug tunnels, called tendon sheaths, that keep the tendons in place next to the bones. Tendon sheaths keep the tendons in place.
What is the toe bone called?
Phalanges (singular: phalanx) – the 14 bones that make up the toes. The big toe consists of two phalanges – the distal and proximal. The other toes have three. Sesamoids – two small, pea-shaped bones that lie beneath the head of the first metatarsal in the ball of the foot.
What are the ankle bones called?
talus
The ankle is a large joint made up of three bones: The shin bone (tibia) The thinner bone running next to the shin bone (fibula) A foot bone that sits above the heel bone (talus)
What is the metacarpal phalangeal joint?
The metacarpophalangeal joint or MP joint, also known as the first knuckle, is the large joint in the hand where the finger bones meet the hand bones. The MCP joint acts as a hinge joint and is vital during gripping and pinching. When arthritis affects the MP joint, the condition is called MP joint arthritis.

Where are tendons in your wrist?
Tendons of the wrist connect muscles to bones. Tendons of the wrist flexors are found on the palmar (palm) side and help in bending the wrist forward. The tendons of the wrist extensors are found on the dorsal (back) side and help in bending the wrist backward.
What is the wrist joint called?
radiocarpal joint
The wrist joint also referred to as the radiocarpal joint is a condyloid synovial joint of the distal upper limb that connects and serves as a transition point between the forearm and hand. A condyloid joint is a modified ball and socket joint that allows for flexion, extension, abduction, and adduction movements.
What are the 28 phalanges?
