Match the bone or bony structure with the structure with which it articulates.

Multiple indentations can be found on the inferior aspect of the clavicle. The costoclavicular ligament attaches to one of the indentations, which also acts as an attachment point for the clavicles and first ribs. Other grooves and indentations are required for sternoclavicular joint stabilization as well as providing a subclavius muscle attachment site. The conoid tubercle is located on the lateral aspect of the clavicle, making and solidifying the conoid ligament attachment between the clavicle and scapula. The trapezoid line serves as an attachment point for the trapezoid ligament, which helps to solidify the articulation between the scapula and the clavicle. The articular facet, which connects the clavicle to the acromion of the scapula, is the clavicle’s most lateral feature.
This triangle-shaped bone, also known as the shoulder blade, is situated on the superior, posterior aspect of the thoracic cage and sits or “glides” along it. The posterior face of the scapula can be represented as slightly convex when viewed from a lateral angle, allowing smooth articulation with the convex structures beneath the thoracic wall. The morphological form of the bone is very peculiar in general. This is due to numerous muscle attachments on the scapula’s borders, which is why the scapula’s borders are thicker in contrast to the bone’s thin and delicate body. As previously mentioned, these boundaries have anatomical landmarks, and their nomenclature is linked to their orientation and location within the body. The boundary that surrounds this area is known as the medial or vertebral border (also known as the paravertebral border), and the border that is located farther away from the midline is known as the lateral or axillary border (due to its orientation near the axilla, commonly called the armpit). The superior boundary of the scapula can be identified by moving to the uppermost region of the scapula.
The skeletal system
The human skeleton is divided into two classes of bones. The axial skeleton is made up of all the bones (that form bony structures) that run the length of the body. The appendicular skeleton is made up of the bones that make up the rest of the skeleton and are named that because they are appendages of the axial skeleton. The bones of the shoulder girdle, upper limbs, pelvic girdle, and lower limbs make up the appendicular skeleton.
The scapulae and clavicles make up the pectoral or shoulder girdle. The upper limb bones are bound to the axial skeleton by the shoulder girdle. Muscles that move the shoulders and upper limbs bind to these bones as well.
The bones of the arm (humerus), forearm (radius and ulna), thumb, and hand make up the upper limbs. The humerus is the only bone in the arm, and it articulates with the radius and ulna in the forearm at the elbow joint. The larger of the two forearm bones is the ulna.
Wrist Bones are the bones of the wrist. The carpus (wrist) is made up of eight carpal bones. The sentence “Some Lovers Attempt Positions That They Can’t Manage” is one mnemonic for recalling the carpal bones. The Scaphoid, Lunate, Triquetral, Pisiform, Trapezoid, Trapezium, Capitate, and Hamate are the eight carpal bones of the wrist.

There are three parts to the upper limb. The arm, which is situated between the shoulder and elbow joints; the forearm, which is situated between the elbow and wrist joints; and the hand, which is situated distal to the wrist joints, make up this category. Each upper limb comprises 30 bones. The humerus is the upper arm’s single bone, while the ulna (medially) and radius (laterally) are the forearm’s paired bones. The base of the hand is made up of eight bones, each of which is called a carpal bone, and the palm is made up of five bones, each of which is called a metacarpal bone. There are 14 bones in the fingers and thumb, each of which is a phalanx bone of the hand.

The skeletal system is required to support the body, protect internal organs, and enable an organism to move. These functions are performed by three separate skeleton designs: hydrostatic skeleton, exoskeleton, and endoskeleton.
A hydrostatic skeleton is one that is created by the coelom, a fluid-filled compartment within the body. The aqueous fluid that supports the organs of the coelom also prevents external compression. Because of the fluid, this compartment is under hydrostatic pressure and protects the organism’s other organs. Soft-bodied animals including sea anemones, earthworms, Cnidaria, and other invertebrates have this sort of skeletal system (Figure 19.2).
Muscles that surround the coelom provide movement in a hydrostatic skeleton. A hydrostatic skeleton’s muscles contract to adjust the shape of the coelom, while the fluid pressure in the coelom induces movement. Earthworms, for example, travel through peristalsis, which is a series of muscular contractions of the skeletal muscle of the body wall hydrostatic skeleton that alternately shorten and lengthen the body. The anterior end of the organism is expanded by lengthening the body. The majority of species have a system for anchoring themselves in their environment. The posterior part of the body is then pulled forward by shortening the muscles. While a hydrostatic skeleton is ideal for invertebrates including earthworms and some aquatic species, it is ineffective for terrestrial animals.
