Bones & Cartilage & Fractures Flashcards
3 types of joint
fibrous
cartilaginous
synovial
fibrous joint characteristic
STABILITY
cartilaginous joint characteristic
stability + mobility
synovial joint characteristic
MOBILITY
Syndesmoses
FIBROUS
unites bones with fibrous sheet
RIGHT INTEROSSEOUS MEMBRANE
Sutures

Cartilaginous Joints
2
Primary
Secondary
Synchondroses
Primary cartilaginous
Hyaline cartilage at end of bones
(long bone epiphyseal growth plate)
Secondary Cartilaginous
intervertebral discs
Synovial Joints
2 + bones articulating with each other
hyaline cartilage at ends of bone
5 sub types
Endochondral ossification
Process in which an initial small hyaline cartilage version grows and turns into none (ossifies)
Each bone has
Epiphysis
Diaphysis
Metaphysis
Epiphysial growth plate
Structure of a bone
Outer cortex
Inner medulla
Bone marrow
Periosteum
Fibrous connective tissue ‘sleeve’ of a bone
Fracture healing
Fracture
Callus
Callus remodelling
Healed
Le fort I
a floating palate
Le fort II
a floating maxilla
Le fort III
a floating face
Vertebral column classes
CERVICAL -7 THORACIC -12 LUMBAR -5 SACRAL -5 COCCYGEAL -4 fused
Curvatures of vertebral column
(Primary to foetus) Secondary cervical Primary thoracic Secondary lumbar Primary sacral
Vertebral body
Spinous process Transverse process Inferior and superior articular process Vertebral body Vertebral foramen Vertebral arch
Facet joint
Between articular processes of 2 adjacent vertebrae
C1 ATLAS
Does not have a body or spinous process
Posterior arch and anterior arch
C2 AXIS
Odontoid process
Projects superiorly from body
C7 PROMINENCE
First palatable spinous process in 70% of people
