An articulation is a joint between a bone and another bone, cartilage, or tooth.

All articulations contain some type of cartilage.

Arthrology is the scientific study of articulations.

Articulations can range in motion from freely mobile to immobile.

There are three structural categories of articulations.

All articulations contain some type of cartilage.

The term diarthrosis refers to a joint that is

Freely mobile

The sagittal suture is a(n)

fibrous joint

An articular capsule is present in

synovial joints

Gomphoses

are found only in tooth sockets

In fibrous joints, the articulating surfaces are held together by

dense regular connective tissue.

synchondrosis

What type of cartilage is located between the bones in a symphysis?

Fibrocartilage

Which is not true about synovial joints?

All articulating bone surfaces are covered with articular cartilage.

Synovial joints are enclosed by fibrous articular capsules.

Synovial fluid is secreted by the synovial membrane.

Ligaments strengthen and reinforce joints.

Blood circulates within the joint cavity to nourish the articular cartilage.

Blood circulates within the joint cavity to nourish the articular cartilage.

Which is not a function of synovial fluid?

Nourishes osteocytes

Lubricates articulating surfaces

Removes wastes

Serves as shock absorber

Distributes stress forces across articular surfaces

Nourishes osteocytes

Which is not true regarding ligaments?

Intracapsular ligaments are within the articular capsule.

Ligaments are composed of dense regular connective tissue.

Extrinsic ligaments are physically separate from the articular capsule.

Intrinsic ligaments are thickenings of the articular cartilage.

Extracapsular ligaments are outside the articular capsule.
