Lecture 12: Articulations

Which is not one of the 3 structural classifications of joints?

• Fibrous

• Synovial

• Cartilaginous

• Hyaline

What are the 3 functional classifications of joints?

• Synarthroses

• Diathroses

• Amphiarthroses

• Synovial

What are the 3 axis of movement?

• Uniaxial- motion in a single plane

• Multiaxial- several directions of movement

• Biaxial- movement in two planes

• triaxial- 3 directions of movement

Synovial Joints are found primarily in the appendicular skeleton

• True

• False

What are the 3 types of cartilaginous joints?

• Fibrocartilage: strongest cartilage and forms immovable joints.

• Hyaline Cartilage- weaker and allows more movement.

• Sternal cartilage - composed of hyaline cartilage; connects ribs to sternum.

• Reticular cartilage

Fibrous joints move a lot

• True

• False

Synovial Fluid cushions the ends of bones and reduces friction when joints move

• False

• True

Which of the following are categories of Synovial joints?

• Plane: uniaxial; gliding joints; found between carpals and tarsals

• Saddle: mostly biaxial; bone fits like a rider sitting on a saddle; thumb

• Hinge: mostly uniaxial; elbow

• Hinge: mostly uniaxial; elbow

• Ellipsoid: mostly biaxial; knuckle & Pivot: uniaxial; verterbral column

Answer explanation

The temporomandibular joint is a joint named according to the bones that join together

• True

• False

Sutures are an example of fibrous joints

• False

• True
