Hinge Joint. Characteristics. There is an elevated ridge present on the dorsal surface of the scapula bone, which is known as the spine. The head of the radius has a cylindrical form, and on its upper surface is a shallow cup or fovea for articulation with the capitulum of the humerus.The circumference of the head is smooth; it is broad medially where it articulates with the radial notch of the ulna, narrow in the rest of its extent, which is embraced by the annular ligament. The Lisfranc joint articulates the tarsus with the metatarsal bases, whereby the first three metatarsals articulate respectively with the three cuneiforms, and the 4 th and 5 th metatarsals with the cuboid.. A caudally pointing process found close to the caudal aspect of the glenoid cavity. The clavicle is the only long bone in the body that lies horizontally.Together with the shoulder blade, it makes up the shoulder girdle. small bump on the humerus, often called the funny bone. The index metacarpal is the most firmly fixed, while the thumb metacarpal articulates with the trapezium and acts independently from the others. In human anatomy of the arm, the capitulum of the humerus is a smooth, rounded eminence on the lateral portion of the distal articular surface of the humerus.It articulates with the cupshaped depression on the head of the radius, and is limited to the front and lower part of the bone.. The clavicle articulates with the scapula here, at the tip of the acromion. The acromion forms the bony tip of the superior shoulder region and articulates with the lateral end of the clavicle, forming the acromioclavicular joint (see (Figure)). The acromion is a part of the scapula bone or shoulder blade of the pectoral girdle. The index metacarpal is the most firmly fixed, while the thumb metacarpal articulates with the trapezium and acts independently from the others. The scaphoid is situated between the proximal and distal rows of carpal bones.It is located on the radial side of the wrist, and articulates with the radius, lunate, trapezoid, trapezium, and capitate. In non-human tetrapods, the name capitellum is generally used, with "capitulum" limited to the 0 votes . The first metacarpal bone is short and thick with a shaft thicker and broader than those of the other metacarpal bones. 1) Manubrium of the sternum; head of the humerus 2) Manubrium of the sternum; acromion of the scapula 3) Head of the humerus; acromion of the scapula 4) Acromion of the scapula; manubrium of the sternum 5) Head of the humerus; manubrium of the sternum Structural Features of Synovial Joints. (?-kr?m?-on) [TA] The lateral end of the spine of the scapula, which projects as a broad flattened process overhanging the glenoid fossa; it articulates with the clavicle and gives attachment to parts of the deltoid and trapezius muscles. Play this game to review Human Anatomy. The spine and fossae give attachment to muscles that act in rotating the arm. The middle metacarpals are tightly united to the carpus by intrinsic interlocking bone elements at their bases. The dorsal border of the cat scapula positions dorsal to the thoracic spinous process. What does the coracoid process articulate with? It is commonly known that the shoulder joint has a loose capsule, making it the most commonly dislocated joint in the human body, of which 90% of these dislocations are anterior. j. trochlea. The walls of this space are formed by the articular capsule, a fibrous connective tissue structure that is attached to each bone just outside the area of the bones articulating surface.The bones of the joint articulate with each other within the joint cavity. The joint between coracoid process and humeral head trapezius territory. Here, the head of the radius is largely encircled by a ligament that holds it in place as it articulates with the radial notch of the ulna. There are two clavicles, one on the left and one on the right. Is acromion process a bone?

C. the acromion process, coracoid process, and glenoid cavity. The elbow is a hinge joint with a rotatory component where the trochlea forms the convex, proximal surface which articulates with the concave, distal surface on the ulna, the trochlear notch. The acromion forms the bony tip of the superior shoulder region and articulates with the lateral end of the clavicle, forming the acromioclavicular joint (see Figure 8.3). In human anatomy of the arm, the capitulum of the humerus is a smooth, rounded eminence on the lateral portion of the distal articular surface of the humerus.It articulates with the cupshaped depression on the head of the radius, and is limited to the front and lower part of the bone..

Apart from this one very movable bony linkage, the scapula is held onto the body entirely by muscles. Which of the following groups of bones, based The dorsal, flat, the triangular body of scapula has a slightly elevated ridge called as the spine which projects as a flat, expanded process called as the 'acromion'. In non-human tetrapods, the name capitellum is generally used, with "capitulum" limited to the Transverse processes Spinous process Inferior articular processes Superior articular processes. Os acromiale is a developmental aberration in which the distal acromion fails to fuse. The clavicle, or collarbone, is a slender, S-shaped long bone approximately 6 inches (15 cm) long that serves as a strut between the shoulder blade and the sternum (breastbone). The ring metacarpal is somewhat more mobile while the fifth metacarpal is semi-independent.

The end of the spine projects as a flattened and expanded process called acromion. Explanation of correct option: Acromioclavicular joints are formed when the acromion process articulates with the clavicle or collarbone. The shoulder joint is a joint that connects the upper limb to the axial skeleton. 5. The clavicle meets the scapula at the top of the shoulder where it connects to the acromion process, forming the acromioclavicular joint (AC joint).
