Question

The Elbow joint is an example of?

• A. pivot joint
• B. ball and socket joint
• C. gliding joint
• D. hinge joint

Answer 1

The correct option is D

hinge joint

The correct answer is option D.

The explanation for the correct option:

1. Joints in the human body is where bones are connected.
2. A hinge joint is a popular type of synovial joint, which is present between two or more bones. This joint allows the movements in one plane only. The knee joint is the best example of a hinge joint.
3. They work by permitting limited motion in other planes while enabling flexion and extension in one plane. A crucial part of the intricate biomechanics of the human body is the hinge joint. The knee, elbow, and ankle can withstand significant forces and facilitate work.
4. The humerus, ulna, and radius are the three bones that make up the elbow, which is a hinge joint. Cartilage holds the ends of the bones together.
5. The forearm may be extended and bent because of the position of the bones in the elbow joint, which creates a hinge like a synovial joint.

Explanation for the incorrect options:

Option A

1. In the anatomy of vertebrates, the pivot join is also known as the rotary joint or the trochoid joint, s a freely movable joint (diarthrosis) that only permits rotation around a single axis.
2. A ring made of a second bone and a nearby ligament spins around the moving bone.
3. The rounded end of one bone fits into a ring that is produced by the other bone to form a pivot joint.

Option B

1. The synovial joint that allows for the most movement is the ball-and-socket joint.
2. The ball-and-socket joint is made up of a ball-shaped surface on one of the bones that slide into a cup-shaped depression on the other bone that is connected to it.
3. The ability to move over an infinite number of different axes that essentially share the same center of motion is what allows the ball socket joint to move freely.

Option C

1. A synovial joint that allows for sliding or gliding motion is called a gliding joint.
2. It is constructed between two bones that contact on flat articular surfaces.
3. The wrist joint is an illustration of a gliding joint. The joints between two vertebrae, ankle joints, acromioclavicular joints, etc. are examples of other gliding joints.

Final answer: The Elbow joint is an example of a hinge joint.
