Musculoskeletal Anatomy Flashcards
What are the classification of bones (7)
Long Short Flat Irregular Sesamoid Intra-Cartilaginous ossification Intra-membranous ossification
Intra-Cartilaginous ossification is all long bones except which bone
Clavicle
Which bone is the First bone to begin ossification and the last on to completely ossify
Clavicle
Many joints are classified according to what
their movements, axes of movement or their structure
What are the joint classifications based on movement
Synarthrosis
Amphiarthrosis
Diarthrosis
How much movement is in a Synarthrosis (Fibrous) joint, Amphiarthrosis (Cartilaginous) Joint and a Diarthrosis (synovial) joint
Synarthrosis - Immobile
Amphiarthrosis - Slightly movable
Diarthrosis - Mobile
when based on Axis of movement how are the joints classified
Uniaxial (Flexion/extension)
Biaxial (F/E and internal/external rotation)
Multiaxial (F/E, I/E rot., abduction and adduction)
When based on structure how are joints classified
Fibrous, Cartilaginous and Synovial
Fibrous joints are further broken down into what
Synostosis (sutural)
Syndesmosis (interosseous Membrane)
Gomphosis (tooth and tooth socket in the gum)
Cartilaginous joints are further subdivided into what
Synchondrosis (primarily cartilaginous (growing end of long bones))
Symphysis (secondary cartilaginous (IVD & Pubic symphysis)
Synovial joints are also known as what
diarthrosis
Many joints are mixed like the
Sacroiliac joint
what happens to the sacroiliac joint as one ages
it become synostosis
what are the six types of synovial joints
Planar (gliding) Ginglymus (hinge) Trochoid (pivot) Condylar (ellipsoidal) Sellar (saddle) spheroidal (ball and socket)
All MIDLINE joints are what secondary cartilaginous except what
median atlanto-axial (atlantodental) joint &
Interparietal joint
