No it is an example of a third class lever
The type of joint that allows for turning movements is called a pivot joint. An example of a pivot joint is the atlantoaxial joint between the first and second cervical vertebrae, which enables the head to rotate. Another example is the proximal radioulnar joint, which allows for the rotation of the forearm. These joints facilitate rotational motion around a single axis.
The cubital joint is an example of a hinge joint. This type of joint allows movement in one plane, like bending and straightening, similar to how the elbow functions.
The calcaneus and the talus or not an example of a pivot joint. There is a pivot joint in the neck between the first and second cervical vertebrae. Another pivot joint is between the radius in the ulna at the wrist.
A fibrous joint is an immovable joint. An example would be the bones in the skull.
A synovial joint is a class of joint with great movement due to its unique structure that allows for a wide range of motion. They are found in the knees, shoulders, and elbows, among other places in the body. The synovial fluid within these joints helps to lubricate and reduce friction as the bones move against each other.
First, second, and third class levers.An example of a first-class lever is the joint between the skull and the atlas vertebrae of the spine: the spine is the fulcrum across which muscles lift the head.An example in the human body of a second-class lever is the Achillestendon, pushing or pulling across the heel of the foot.An example of a third-class lever in the human body is the elbow joint: when lifting a book, the elbow joint is the fulcrum across which the biceps muscle performs the work.Source(s):http://www.science-class.net/Anatomy/Sup…
A star jump is an example of a second-class lever, where the load is situated between the fulcrum and the effort (in this case, your body weight is the load, your hip joint is the fulcrum, and your muscles are the effort).
Yes, scissors are a type of second-class lever. In a second-class lever, the load is situated between the fulcrum and the effort. In the case of scissors, the fulcrum is located at the joint, the load is the material being cut, and the effort is applied by pressing the handles.
No, tipping your head back is an example of a third-class lever. In a third-class lever, the effort force is between the fulcrum (joint) and the load (head) being moved.
The biceps is an example of a class 3 lever. The triceps is an example of a class 1 lever.
Nodding the head is an example of a third-class lever, where the effort is applied between the fulcrum (neck joint) and the resistance (head).
When raising dumbells in front of you by using only the forearm, the pivot is the elbow joint; the load is the dumbells at the opposite ends of the arm from the elbow joint; and the position of the effort is where the muscles of the arm are attached by tendons to the arm bones near the wrist. This is a third class lever system.

Yes, the elbow joint is an example of a first-class lever, where the effort force (muscle contraction) and load (resistance) are on opposite sides of the fulcrum (joint). When you bend your elbow to lift an object, the effort force from your bicep muscle overcomes the resistance of the load, such as a weight you are lifting.
Ball-and-socket joint is an example of triaxial (or multiaxial) joint.
The atlanto-occipital joint. This is the articulation between the atlas (C1) and the occipital bone.
