Question 1

Dense fibrous connective tissue is to a suture as a periodontal ligament is to a(n)
A) amphiarthrosis.
B) syndesmosis.
C) synostosis.
D) synchondrosis.
E) gomphosis.

Accepted Answer

A periodontal ligament is a dense fibrous connective tissue that attaches teeth to the surrounding alveolar bone in a gomphosis joint.

Question 2

Syndesmosis is to ligament as symphysis is to
A) fibrous cartilage.
B) dense regular connective tissue.
C) periodontal ligament.
D) rigid cartilaginous bridge.
E) completely fused.

Accepted Answer

Syndesmosis and ligament are both forms of fibrous connective tissue, so the analogy is asking for another type of fibrous connective tissue. Symphysis is an example of fibrous cartilage, which connects bones with a pad of fibrous tissue (intervertebral discs and pubic symphysis are examples of symphysis).

Question 3

Bursae are found in all of the following areas except
A) tendon sheaths.
B) beneath the skin covering a bone.
C) within connective tissue exposed to friction or pressure.
D) around blood vessels.
E) around many synovial joints.

Accepted Answer

Bursae are small fluid-filled sacs that reduce friction between moving parts in the body, such as muscles, tendons, and bones. They are commonly found in areas subject to friction or pressure, including tendon sheaths, beneath the skin covering bones, and around many synovial joints. However, they are not typically found around blood vessels.

Question 4

An epiphyseal line is an example of a
A) gomphosis.
B) synchondrosis.
C) synostosis.
D) symphysis.
E) syndesmosis.

Accepted Answer

An epiphyseal line is the site where the epiphysis and diaphysis of a long bone fuse together during development. This fusion results in the formation of a synostosis, which is a bony joint where two bones fuse together and become immobile. Therefore, the best choice is C, synostosis.

Question 5

Aslightly movable joint is a(n)
A) synarthrosis.
B) diarthrosis.
C) amphiarthrosis.
D) gomphosis.
E) synostosis.

Accepted Answer

A slightly movable joint is referred to as an amphiarthrosis. Synarthroses are immovable joints, diarthroses are freely movable joints, gomphoses are specialized joints that anchor teeth to the jawbone, and synostoses are joints that have fused and are immovable.

Question 6

An immovable joint is a(n)
A) synarthrosis.
B) diarthrosis.
C) amphiarthrosis.
D) syndesmosis.
E) symphysis.

Accepted Answer

An immovable joint is also known as a synarthrosis joint. These joints allow minimal to no movement between bones and are commonly found in the skull sutures, teeth sockets, and connecting the spinal vertebrae.

Question 7

Which of the following is one of the four major types of synarthrotic joints?
A) suture
B) gomphosis
C) synchondrosis
D) synostosis
E) All of the answers are correct.

Accepted Answer

All of the options listed (suture, gomphosis, synchondrosis, and synostosis) are types of synarthrotic joints, which are characterized by their immobility or very limited mobility.

Question 8

Aligamentous connection such as an antebrachial interosseous membrane is called a
A) syndesmosis.
B) symphysis.
C) synchondrosis.
D) synostosis.
E) gomphosis.

Accepted Answer

A syndesmosis is a type of fibrous joint where bones are connected by ligaments or interosseous membranes, such as the antebrachial interosseous membrane between the radius and ulna in the forearm. Symphysis, synchondrosis, synostosis, and gomphosis are all different types of joints with different structural characteristics.

Question 9

An example of a synchondrosis is the articulation of the
A) ribs with the sternum.
B) radius and the ulna.
C) femur with the acetabulum.
D) atlas and the axis.
E) navicular bone with the cuniform bones.

Accepted Answer

The articulation of the ribs with the sternum is an example of a synchondrosis, which is a type of cartilaginous joint where the bones are joined by hyaline cartilage, such as the costochondral joints of the ribs with the sternum.

Question 10

Asuture is an example of a(n)
A) synarthrosis.
B) syndesmosis.
C) symphysis.
D) diarthrosis.
E) amphiarthrosis.

Accepted Answer

A suture is a type of joint that is immovable, which is classified as a synarthrosis. Sutures are found between the bones of the skull.

Question 11

Which of the following is not a property of articular cartilage?
A) covered by perichondrium
B) lubricated by synovial fluid
C) enclosed by an articular capsule
D) similar to hyaline cartilage
E) smooth, low-friction surface

Accepted Answer

Articular cartilage is not covered by perichondrium. It is avascular and receives nutrients through diffusion from the synovial fluid.

Question 12

Which of the following occurs when the articular cartilage is damaged?
A) The matrix begins to break down.
B) The exposed surface appears rough.
C) Friction in the joint increases.
D) Normal synovial joint function is unable to continue.
E) All of the answers are correct.

Accepted Answer

When the articular cartilage is damaged, the matrix begins to break down, the exposed surface appears rough, friction in the joint increases, and normal synovial joint function is unable to continue. Therefore, all of the answers are correct.

Question 13

Identify the incorrect pair.
A) synarthrosis; immovable joint
B) amphiarthrosis; slightly movable joint
C) chondrosis; freely moving joint
D) gomphosis; articulation between tooth and bone
E) They are all correct; there is no incorrect pair.

Accepted Answer

Chondrosis is not a term used to describe any type of joint. It refers to a degenerative process in cartilage.

Question 14

Structurally, the pubic symphysis is classified as a ________ articulation.
A) cartilaginous
B) bony
C) synovial
D) fibrous
E) diarthrotic

Accepted Answer

The pubic symphysis is a cartilaginous joint, meaning it is connected by cartilage, rather than bone or a synovial membrane.

Question 15

A freely movable joint is a(n)
A) synarthrosis.
B) diarthrosis.
C) amphiarthrosis.
D) syndesmosis.
E) symphysis.

Accepted Answer

A freely movable joint is also known as a diarthrosis.

Question 16

The intervertebral disc joint is called a
A) synarthrosis.
B) glide joint.
C) condylar joint.
D) synchondrosis.
E) symphysis.

Accepted Answer

The intervertebral disc joint is a type of cartilaginous joint called a symphysis. This is because it is composed of fibrocartilage and allows for limited movement and a degree of flexibility between adjacent vertebrae.

Question 17

Joints can be classified structurally as
A) bony.
B) fibrous.
C) cartilaginous.
D) synovial.
E) All of the answers are correct.

Accepted Answer

Joints are classified structurally into bony, fibrous, cartilaginous, and synovial types, each with distinct characteristics and functions within the body.

Question 18

Which of the following is not a function of synovial fluid?
A) shock absorption
B) increases osmotic pressure within joint
C) lubrication
D) provides nutrients
E) protects articular cartilages

Accepted Answer

Synovial fluid does not increase osmotic pressure within the joint. It does, however, perform the functions of lubricating the joint, providing nutrients to the articular cartilage, protecting articular cartilages, and absorbing shock.

Question 19

Asynovial joint is an example of a(n)
A) synarthrosis.
B) amphiarthrosis.
C) diarthrosis.
D) symphysis.
E) syndesmosis.

Accepted Answer

An asymmetrical joint is an example of a diarthrosis, which is a joint that is freely movable, such as a ball-and-socket joint or a hinge joint.

Question 20

The synarthrosis that binds the teeth to the bony sockets is a
A) suture.
B) gomphosis.
C) synchondrosis.
D) synotosis.
E) syndesmosis.

Accepted Answer

The type of synarthrosis that binds the teeth to the bony sockets is a gomphosis. A gomphosis is a specialized type of joint where a conical or peg-like process fits into a socket, such as the connection between the teeth and the jaws. Sutures (A) are immovable joints that connect the bones of the skull, synchondrosis (C) refers to cartilaginous joints which are connected by hyaline cartilage, and syndesmosis (E) refers to fibrous joints where bones are connected by ligaments. Synotosis (D) is not a valid term used in this context.
