Skeletal fractures and diseases

How do you describe the fingertips, the middle of the fingers, and the base of the fingers?

Proximal - base of the finger

Intermediate - middle of the finger

distal- fingertips

What are the three ways we can classify joints based on their movements

Synarthrotic: not moveable - aka sutures

Amphiarthrotic: slightly moveable -like vertebrae

Diathrotic: fully moveable -aka synovial joints

What are the four types of diathrotic joints? provide an example of each kind.

Ball and socket- Femur and pelvis

Hinge- Humerus and Ulna

Pivot- Radius and radius

saddle - Pollex

What is synovial liquid

Fluid within the joints that helps to lubricate

Briefly describe the eight types of bone structures

Closed(or simple)- A fracture in which the skin remains intact

Open(or compound)- A fracture in which at least one end of the broken bone tears through the skin; carries high risk of infection

Transverse- Occurs straight across the long axis of the bone

Spiral- Bone segments are pulled apart as a result of a twisting motion

Impacted- One fragment is driven into the other, usually a results of compression

Comminuted- Several breaks result in many small pieces between two large segments.

Oblique- Occurs at an angle that is not 90 degrees

Greenstick- A partial fracture in which only one side of the bone is broken
