Study Notes
Carpal Bones
- Comprise eight small bones in the wrist: Scaphoid, Lunate, Triquetrum, Pisiform, Trapezium, Trapezoid, Capitate, Hamate.
- Facilitate a range of wrist movements and support hand function.
Scaphoid
- Largest carpal bone in the proximal row.
- Located near the base of the thumb; important for wrist stability.
Lunate
- Positioned between scaphoid and triquetrum.
- Has a crescent shape and contributes to wrist mobility.
Triquetrum
- Located on the medial side of the wrist, articulates with the pisiform.
- Provides support and aids in wrist movement.
Pisiform
- A small, pea-shaped bone located on top of the triquetrum.
- Functions as a pulley for tendons of the flexor carpi ulnaris.
Trapezium
- Most lateral carpal bone in the distal row, articulates with the first metacarpal.
- Supports the base of the thumb and facilitates thumb opposition.
Trapezoid
- A wedge-shaped bone located medial to the trapezium.
- Provides structural support for the second metacarpal.
Capitate
- The largest carpal bone located in the center of the wrist.
- Articulates with the third metacarpal; crucial for grip strength.
Hamate
- Has a hooked shape, located on the ulnar side of the wrist.
- Contains a prominent hook that serves as an attachment point for ligaments.
Metacarpals
- Five long bones in the hand; numbered 1-5 from thumb (I) to pinky (V).
- Form the skeletal framework of the palm.
Phalanges of the Hand
- Comprise the finger bones divided into three types: proximal, middle, and distal.
- Each finger has three phalanges; the thumb has two.
Proximal Phalanges of the Hand
- The first segment of each finger, connecting to the metacarpals.
- Essential for finger flexion and mobility.
Middle Phalanges of the Hand
- Present in the fingers (not in the thumb).
- Act to allow for finer movements of the fingers.
Distal Phalanges of the Hand
- The tip bones of each finger, crucial for tactile sensitivity and grip.
Tarsal Bones
- Comprise seven bones forming the ankle and back of the foot.
- Include the Calcaneus, Talus, Navicular, and three cuneiforms, along with Cuboid.
Calcaneus
- The heel bone, largest tarsal bone, bears weight and provides stability during walking.
Talus
- Sits above the calcaneus and articulate with the bones of the lower leg.
- Involved in dorsiflexion and plantarflexion of the foot.
Navicular
- Located anterior to the talus and serves as a connection point for several tarsal bones.
Medial Cuneiform
- The first of the three cuneiform bones; located in the medial part of the foot.
- Supports the first metatarsal.
Intermediate Cuneiform
- The middle cuneiform, located between the medial and lateral cuneiforms.
- Contributes to foot arch stability.
Lateral Cuneiform
- The third cuneiform bone, located more laterally than the other two.
- Provides support to the second and third metatarsals.
Cuboid
- A cube-shaped bone located on the lateral side of the foot.
- Articulates with metatarsals and supports the lateral foot arch.
Metatarsals
- Five long bones in the foot; numbered 1-5, beginning with the big toe.
- Form the arch and structure of the foot.
Phalanges of the Foot
- Comprised of proximal, middle, and distal phalanges similar to the hand.
- Important for balance and mobility.
Proximal Phalanges of the Foot
- The first segment of each toe, connecting to the metatarsals.
Middle Phalanges of the Foot
- Present in the toes (except in the big toe).
- Facilitate toe manipulation.
Distal Phalanges of the Foot
- The tip bones of each toe, aiding in balance and support.
Thumb to Pinky Numbering
- Phalanges of the hand are numbered from the thumb (1) to pinky (5).
Big Toe to Pinky Toe Numbering
- Phalanges of the foot are similarly numbered from the big toe (1) to pinky toe (5).
