A condyloid joint (4 answers)

can be found in the wrist. is considered to be biaxial. is also called an ellipsoidal joint. allows both flexion-extension and abduction-adduction of the joint.

Which of the following is NOT an anatomical component of the elbow? radial collateral ligament. tendon of the biceps brachii muscle. articular capsule. ulnar collateral ligament. anular ligament of the radius.

tendon of the biceps brachii muscle

Bending the trunk forward at the intervertebral discs is an example of what type of angular movement?

Flexion

Which of the following represents a type of movement where there is a decrease in the angle between articulating bones?

Flexion

Flexion and extension usually occur along which plane?

Sagittal

Which of the following structures is used to reduce friction in joints? 1. Bursae 2. Synovial fluid 3. Accessory ligaments 4. Elastic fibers

1 and 2

Which ligament limits hyperextension of the knee and prevents the anterior sliding of the tibia on the femur?

Anterior cruciate ligament

What unique characteristics would a person who is "double-jointed" possess?

Double-jointed people do not have extra joints. They have greater flexibility in their articular capsules and ligaments. The resulting increase in the range of motion allows them to do such moves as touching their thumbs to their wrists and putting their ankles or elbows behind their necks. Unfortunately, such flexible joints are structurally less stable and are more easily dislocated

Which of the following is NOT a factor affecting range of motion of a joint? Tension of the muscles Hormones Disuse Eversion Structure of articulating bones

Eversion

Which type of motion results from relatively flat bone surfaces moving back and forth and from side to side with respect to one another?

Gliding

Which of the following is NOT a common characteristic of synovial joints? Include elastic cartilage Have ligaments holding the joint together Articulating bones are covered with hyaline cartilage Contain a joint cavity Are freely moveable

The epiphyseal plate in a long bone is an example of which type of joint?

Synchondrosis

Based on the structural classification of joints, which of the following is a fibrous joint?

Syndesmosis

List the three functional classifications of joints, and briefly describe the basis for the functional classification of joints.

The functional classification joint is based on the degree of movement that they allow. The three functional classes are: 1) synarthroses, which are totally immovable, 2) amphiarthroses, which have slight movement, and 3) diarthroses, which are freely moveable joints.

List the three structural categories of joints and briefly describe the criteria used for structural classification of joints.

The structural types of joints include: 1) fibrous joints, 2) cartilaginous joints, and 3) synovial joints. Joints can be classified structurally based on two criteria: 1) the presence or absence of a space between the articulating bones, called a synovial cavity and 2) the type of connective tissue that binds the bones together.

The joint between the first rib and the manubrium of the sternum is classified as (3 answers)

a synchondrosis. a synarthrosis. a cartilaginous joint.

Which of the following is a correct description of arthroplasty?

surgically replacing a joint with an artificial joint
