Q

Axial skeleton review:

A

Skull, Vertebral column, and pelvis
-provides anchorage to the appendicular skeleton and protects vital organs
Vertebral column: Cervical (7), Thoracic (12), Lumbar (5), Sacrum, Coccyx
Pelvis: Ilium (2 elephant bones), Ischium (2 sit bones), Pubis (2 inner bones)

A

Articulations
-the motion observed occurs at the joint, not within the segments

Q

Diarthrodial (synovial) Joints

A

Low friction, high resistance to wear and tear
Types: Plane/ gliding. Hinge, Pivot, Condylar, Ellipsoid, Saddle, Ball and Socket
Stability can be provided by the structure, surrounding ligaments, capsule, tendons, gravity

Q

Joint Positions: Closed vs Loose packed positions

A

Closed: maximum contact between surfaces, maximum compression, forces travel through the joint -ex) full extension of knee

Loose: all other joint positions, less contact area between surfaces

Q

Synoarthrodial (fibrous) Joints

A

Bones held together by fibrous articulations
-allows for little or no movement
Ex) sutures in skull

Q

Amphiarthrodial (cartilaginous) Joints

A

-little movement
Ex) in vertebral discs
