1. What is the term for bony joints?

Synostosis
synarthrotic
ossification of fibrous or cartilaginous joints

Suture joints

Synarthrosis

Ligamentous joints

Bony joints are typically referred to as synostosis, which involves the ossification of fibrous or cartilaginous joints.

Explanation

Bony joints are typically referred to as synostosis, which involves the ossification of fibrous or cartilaginous joints.

2. What type of joints are fibrous joints?

Synarthrotic
or synarthrodial joint
adjacent bones are bound by collagen fibers that emerge from one bone
sutures, gomphoses, and syndesmoses

Synovial

Diarthrotic

Amphiarthrotic

Fibrous joints are immovable (synarthrotic) joints where adjacent bones are bound by collagen fibers that emerge from one bone, such as sutures, gomphoses, and syndesmoses.

Explanation

Fibrous joints are immovable (synarthrotic) joints where adjacent bones are bound by collagen fibers that emerge from one bone, such as sutures, gomphoses, and syndesmoses.

3. What type of joint are sutures?

Amphiarthrotic

Diarthrotic

Synarthrotic

Fibrous

Sutures are immovable joints, meaning they do not allow for any movement between the connected bones. This characteristic classifies them as synarthrotic joints.

Explanation

Sutures are immovable joints, meaning they do not allow for any movement between the connected bones. This characteristic classifies them as synarthrotic joints.

4. Where is the sagittal suture located?

Temporal bones

Occipital bone

Frontal bone

Between parietal bones

The sagittal suture is the joint between the two parietal bones of the skull, running from the top of the head down to the back.

Explanation

The sagittal suture is the joint between the two parietal bones of the skull, running from the top of the head down to the back.

5. Where is the coronal suture located on the human skull?

At the lateral margin

At the posterior margin

At the anterior margin

At the superior margin

The coronal suture is located at the anterior margin of the human skull where the frontal bone meets the parietal bones. It is one of the main sutures that connect the different bones of the skull.

Explanation

The coronal suture is located at the anterior margin of the human skull where the frontal bone meets the parietal bones. It is one of the main sutures that connect the different bones of the skull.

6. Where is the lambdoid suture located?

At the lateral margin

At the upper margin

At the lower margin

At the posterior margin

The lambdoid suture is located at the posterior margin of the skull where the parietal bones meet the occipital bone.

Explanation

The lambdoid suture is located at the posterior margin of the skull where the parietal bones meet the occipital bone.

7. Where is the squamous suture located?

Laterally

Superiorly

Anteriorly

Posteriorly

The squamous suture is located laterally in the skull, connecting the parietal bones to the temporal bones.

Explanation

The squamous suture is located laterally in the skull, connecting the parietal bones to the temporal bones.

8. What type of joint are syndesmoses?

Amphiarthrotic

Diarthrotic

Fibrous

Synarthrotic

Syndesmoses are joints in which bones are connected by ligaments, allowing for slight movement. This type of joint is classified as amphiarthrotic, meaning it is a slightly movable joint.

Explanation

Syndesmoses are joints in which bones are connected by ligaments, allowing for slight movement. This type of joint is classified as amphiarthrotic, meaning it is a slightly movable joint.

9. What type of joints are cartilaginous joints?

Diarthrosis - freely movable joints.

Fibrous joints - joints connected by dense connective tissue.

Synarthrosis - joints that are immovable.

Amphiarthrosis
two bones linked by cartilage

Cartilaginous joints are known as amphiarthroses, which allow limited movement between the two bones connected by cartilage.

Explanation

Cartilaginous joints are known as amphiarthroses, which allow limited movement between the two bones connected by cartilage.

10. What type of joints are synchrondroses?

Synarthrotic
bones are bound by hyaline cartilage
between epiphysis and diaphysis of a long bone
first rib to the sternum by a hyaline costal cartilage

Suture joints

Amphiarthrosis joints

Diarthrosis joints

Synchrondroses are a type of joint where bones are bound by hyaline cartilage. They are considered synarthrotic, allowing for little to no movement between the bones involved. Examples include the connection between epiphysis and diaphysis of a long bone and the first rib to the sternum by a hyaline costal cartilage. Amphiarthrosis joints allow for slight movement, diarthrosis joints are freely movable, and suture joints are found in the skull and are immovable.

Amphiarthrosis joints allow for slight movement, diarthrosis joints are freely movable, and suture joints are found in the skull and are immovable.

11. What type of joint is a symphysis?

Amphiarthrotic
two bones joined by fibrocartilage
pubic symphysis- R and L pubic bones are joined by the cartilaginous interpubic disc

Diarthrotic

Synarthrotic

Fibrous

Symphyses are joints where two bones are joined by fibrocartilage, allowing for slight movement. This type of joint is known as amphiarthrotic. Diarthrotic joints allow for free movement, synarthrotic joints are immovable, and fibrous joints are connected by collagen fibers.

Explanation

Symphyses are joints where two bones are joined by fibrocartilage, allowing for slight movement. This type of joint is known as amphiarthrotic. Diarthrotic joints allow for free movement, synarthrotic joints are immovable, and fibrous joints are connected by collagen fibers.

12. What is the role of articular cartilage in synovial joints?

To facilitate blood flow within the bones

To provide cushioning in the spinal joints

In synovial joints
facing smooth surfaces of the two bones are covered in this
hyaline cartilage

To allow for smooth movement of tendons and ligaments

Articular cartilage in synovial joints serves as a protective layer that reduces friction between bones during movement.

Explanation

Articular cartilage in synovial joints serves as a protective layer that reduces friction between bones during movement.

13. What are the components of a synovial joint?

Ligament fluid, joint cavity, fibrous membrane, synovial capsule

Cartilage fluid, joint (articular) cavity, synovial capsule, fibrous membrane

--

Tendon capsule, joint (osseous) cavity, synovial fluid, fibrous membrane

A synovial joint is composed of synovial fluid, joint (articular) capsule, fibrous capsule, and synovial membrane.

Explanation

A synovial joint is composed of synovial fluid, joint (articular) capsule, fibrous capsule, and synovial membrane.
