The Sternoclavicular Joint (SC joint) is formed from the articulation of the medial aspect of the clavicle and the manubrium of the sternum. It is one of four joints that compose the Shoulder Complex. The SC joint is generally classified as a plane style synovial joint, and has a fibrocartilage joint disk.

synovial joint

The Acromioclavicular Joint, or AC Joint, is one of four joints that compride the Shoulder complex. The AC Joint is formed by the junction of the lateral clavicle and the acromion process of the scapula and is a gliding, or plane style synovial joint

Front 19

What is the number of phalangeal bones

Back 19

14 (2+3+3+3+3)

Front 20

What type of joint is interphalangeal joint

Back 20

hinge joints (synovial joint)

Interphalangeal Joints. Interphalangeal joints are formed between the phalanges. These are uniaxial type of hinge joints where only possible movement is flexion and extension.

Front 21

What type of joint is the elbow joint

Back 21

The elbow joint is a complex hinge joint formed between the distal end of the humerus in the upper arm and the proximal ends of the ulna and radius in the forearm. The elbow allows for the flexion and extension of the forearm relative to the upper arm, as well as rotation of the forearm and wrist

Front 22

What type of joint is the inter carpal joint

Back 22

Ellipsoid joints (synovial)The intercarpal joints are synovial joints formed between the individual bones of the proximal row of the carpal bones, between the individual bones of the distal row of carpal bones, and between the proximal and distal rows (the midcarpal joint).

What is direction of rotation of preaxial border of upper and lower limb

Back 24

Upper limb (laterally through 90 degree)

Lower limb (medially through 90 degree)

They rotate such that the flexor compartment of muscles is located anteriorly for upper arm where as it is located posteriorly for lower limb.
