BISC Chp. 9

Which of the following structures is used to reduce friction in joints?

1. Bursae 2. Synovial fluid

Which of the following joints is classified as a synarthrosis joint in adults?

1. Gomphosis 2. Synchondrosis 3. Suture

Articular discs

1. maintain the stability of a joint. 2. direct flow of the synovial fluid to areas of greatest friction.

In this type of fibrous joint, the connective tissue is typically arranged either as a bundle or as a sheet.

3. Syndesmoses

Cartilaginous joints

A) 1 only (fibrous joints)

Which of the following is not considered a ìspecial movementî that occurs at only certain joints?

A) Depression B) Protraction C) Elevation D) Supination E) All of these are special movements

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

A) Flexion

This is a type of movement where there is a decrease in the angle between articulating bones.

A) Flexion

Which of the following is(are) made from dense regular connective tissue?

A) Ligaments

In this type of synovial joint, a rounded or pointed surface on one bone articulates with a ring formed partly by another bone and partly by a ligament.

A) Pivot joint

What type of special movement occurs in your clavicles at your acromioclavicular and sternoclavicular joints when you cross your arms in front of your body?

A) Protraction

The joint between the first rib and the manubrium of the sternum is classified as

A) a synchondrosis. B) a synarthrosis. C) a cartilaginous joint. D) All of these choices.

The functional joint classification that a suture joint fits into is

A) synarthrosis.

Which of the following types of joints is also called a dentoalveolar joint?

B) Gomphosis

Another term for menisci is

B) articular discs.

This functional class of joints contains joints that are freely movable.

C) 3 only (diathrosis)

Which of the following is a type of fibrous joint composed of a thin layer of dense irregular fibrous connective tissue found between the bones of the skull?

C) 3 only (suture)

Where do all the symphysis joints in the human body occur?

C) Axial skeleton

This special movement occurs when you bend your foot at the ankle in the direction of the foot's superior surface as would occur when you stand on your heels.

C) Dorsiflexion

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

C) Gliding

Flexion and extension usually occur along which plane?

C) Sagittal

Which of the following types of joints do NOT have a synovial cavity?

D) 1 and 2 (Fibrous & Cartilaginous)

Examples of this type of movement include moving the humerus laterally at the shoulder joint.

D) Abduction

Which of the following structures is NOT used to reduce friction in joints?

D) Accessory ligaments

This type of complex movement involves a continuous sequence of flexion, abduction, extension, and adduction resulting in a distal body part moving in a circle

D) Circumduction

Some examples of these structures include the fibular and tibial collateral ligaments of the knee joint.

D) Extracapsular ligaments

Which of the following is NOT a common characteristic of synovial joints?

D) Include elastic cartilage

Which of the following bones CANNOT be elevated or depressed?

D) Maxilla

Which of the following is NOT a structural category of synovial joints?

D) Suture

This special movement involves moving your thumb across the palm to touch the tips of the fingers on the same hand.

E) Opposition

The epiphyseal plate in a long bone is an example of this type of joint.

E) Synchondrosis
