Skeleton 2 Flashcards
The upper extremities are adapted for:
Flexibility and dexterity
Pieces of the pectoral girdle
Scapula and clavicle
Portion of scapula that articulates with the humorous
Glenoid cavity
Radius and ulna are attached by
Interosseous membrane
Carpals
- scaphoid
- lunate
- triquetral
- pisiform
- trapezium
- trapezoid
- capitate
- hamate
3 categories of phalanges (from closest to metacarpals to farthest)
- proximal
- intermediate
- distal
How many phalanges are in fingers
14
Which type of phalange does the thumb lack
Intermediate
Lower limbs are adapted for:
Weight bearing and locomotion
False pelvis
The large flaring portion of the pelvis
True pelvis
The smaller portion of the pelvis that creates the opening
Innominate bones that fuse to form the pelvis
- ilium
- ischium
- pubis

Upper fan shape
Ischium
Bottom
Pubis
Front
Pubis symphysis
Joint of fibrous cartilage that joins the pelvis in the front
Function of the patella
Acts as a guide for tendons and allows for them to slide smoothly across knee joint
Tarsals
- calcaneus
- talus
- navicular
- cuboid
- lateral cuneiform
- intermediate cuneiform
- medial cuneiform
Function of the arches
Provide extra support and act as shock absorbers

Closed (simple) fracture
Does not penetrate through the skin
Open (compound fracture)
Broken bone penetrates through the skin
Transverse break
Straight across the bone
Oblique fracture
Diagonal break across the bone
Comminuted fracture
Bone breaks into many fragments
Fissure fracture
Cracks in bone
Compression fracture
Bone is crushed
Depressed fracture
Broken portion is pressed inward (common in skull fractures)
Avulsion fracture
Broken pieces have been pulled apart
Impacted fracture
Broken bone ends are forced into eachother
Spiral fracture
Ragged break the occurs due to an excessive twisting force
Green stick fracture
Bone breaks incompletely
