Joints (a & P 1 Lab )

In the context of the skull, a joint is referred to as any joint in the skull. Specifically, it is known as a suture, which is a fibrous joint that is synarthrotic, meaning it is immovable.

The correct term for the joint between a tooth and its alveolar socket is gomphosis, which is a specific type of fibrous joint that is synarthrotic, meaning it does not allow for movement.

The distal (inferior) tibiofibular joint is classified as a fibrous syndesmosis joint, which is a type of synarthrotic joint where bones are united by fibrous connective tissue. It allows for very little movement, providing stability to the ankle joint.

The intervertebral joint is a unique type of joint that connects the vertebral bodies through cartilaginous symphysis, resulting in an amphiarthrotic function allowing limited movement.

The pubic symphasis joint is a type of cartilaginous joint specifically classified as a symphysis, which is functionally classified as amphiarthrotic. This joint allows for limited movement and is held together by fibrocartilage.

The first sternocostal joint is a cartilaginous synchondrosis joint located between the sternum and the 1st rib. It is functionally synarthrotic, allowing for minimal movement and providing stability to the thoracic cage.

The glenohumeral joint, also known as the shoulder joint, is a ball and socket joint that allows for multiaxial movement. It articulates the scapula and humerus, making it a diarthrotic synovial joint.

The coxal joint, also known as the hip joint, is a type of ball and socket joint that allows for multiaxial movement. It is a synovial joint that articulates between the hip bone and femur, providing a high degree of flexibility and mobility in the hip region.

The 1st carpometacarpal joint articulates with the trapezium and the 1st metacarpal bone, allowing for biaxial movement in a saddle joint configuration.

The sternoclavicular joint is classified as a saddle joint due to its unique shape and movement capabilities, allowing for biaxial movement in multiple directions.

The atlantoaxial joint is a type of synovial pivot joint, allowing for uniaxial movement between the first (atlas) and second (axis) cervical vertebrae.

The joint between the radius and ulna is a pivot joint, specifically the proximal radioulnar joint. This type of joint allows for rotation around a single axis.

The distal radioulnar joint is the joint closest to the hand and is specifically classified as a pivot joint. It allows for uniaxial movement between the radius and ulna, contributing to the rotation of the forearm.

The correct answer is the atlanto-occipital joint, which is a condylar joint that allows biaxial movement between the occipital bone and the atlas. It is classified as a synovial joint and functions as a diarthrotic joint.

The radiocarpal joint, also known as the wrist joint, is a condylar joint that allows for biaxial movement. It articulates between the radius and proximal carpal bones, making it a critical joint for wrist movement.

The metacarpo-phalangeal joint is a condylar diarthrotic joint allowing biaxial movement between the metacarpal and proximal phalanx bones.

The correct answer provides the specific details about the temporomandibular joint including its articulating bones, general classification, specific type, functional classification, and degree of movement. The incorrect answers include incorrect articulating bones and joint classifications to test the understanding of joint types.

The elbow joint is classified as a hinge joint, allowing movement primarily in one plane like a door hinge.

The interphalangeal joint in the finger is a specific type of synovial joint known as a hinge joint, allowing for uniaxial movement.

The tibiofemoral joint, located at the knee, articulates between the femur and tibia. It is classified as a synovial joint with a specific hinge movement, allowing for uniaxial motion. It is functionally classified as diarthrotic.

The sternocostal joint articulates the sternum with ribs 2-7, providing movement in the chest area.

The intervertebral joint is a synovial plane joint, belonging to the category of diarthrotic joints and characterized by nonaxial movement.

The costovertebral joint is a specific type of synovial joint where the ribs articulate with the vertebrae. It is classified as a plane joint, allowing for nonaxial movement, making it a diarthrosis joint.

The acromioclavicular joint is a synovial joint with plane-specific movements, making it a diarthrotic joint with nonaxial movement. The incorrect options provided are different types of synovial joints with varying specific movements and degrees of movement.

The intercarpal joint is a synovial plane diarthrotic joint, allowing for nonaxial movement between adjacent carpal bones.

The carpometacarpal joint is a specific type of joint formed by the articulation between the carpal bones and the metacarpal bones of digits 2-5. It is classified as a plane synovial joint, allowing limited nonaxial movements. Other joint types mentioned in the incorrect answers have different articulating structures and functional classifications.

The correct answer is the sacroiliac joint, which is classified as a synovial, plane joint. It functions as a diarthrotic joint with a nonaxial degree of movement.

The femoropatellar joint is a specific type of joint located in the knee that articulates the femur and patella. It is a synovial joint, specifically classified as a plane joint. Functionally, it is diarthrotic, allowing for movement in various directions but is considered nonaxial as it does not involve rotation.
