Joints and Pectoral Girdle Flashcards
is a place where two bones come together.
Joints
based on degree of motion
Functional Classification
based on type of connective tissue that binds the bone together
Structural Classification
3 Functional Classification
- Synarthrosis (non-movable)
- Amphiarthrosis (slightly movable)
- Diarthrosis (freely movable)
3 Structural Classification
- Fibrous
- Cartilaginous
- Synovial
Consist of two bones that are unified by fibrous tissue and that exhibit little to no movement.
Fibrous Joints
Unite two bones by means of cartilage and permits slight movement.
Cartilaginous Joints
Freely movable joints that contain synovial fluid in a cavity surrounding the ends of articulating bones.
Synovial Joints
shoulder girdle
Pectoral Girdle
pectoral girdle is consist po (a) ___ bones: (b) _______ and (c) ________
a. 4
b. 2 scapula
c. 2 clavicle
attach the upper limb to the body and allows free movement of the upper limb
Pectoral Girdle
• S shape bones that can be felt along their entire course as they extend horizontally.
• Proximal end of the clavicle is attached to the sternum
• First bone to begin ossification and last to complete ossification
Clavicle (Collar Bone)
it is a triangular, flat bone, which serves as a site for attachment for many muscles.
Scapula (Shoulder Blade)
