The Clavicle or Collarbone is a Long Bone that Serves as a Strut Between the Shoulder Blade and the breastbone. It is The bone that Connects the Arm to the Body. The Clavicle is a Slender Bone with an ‘S’ Shape. It can be Divided into a sternal end, a shaft and an acromial end. A Clavicle Fracture can be very Painful and may make it Hard to move your Arm.
In Anatomy the Scapula also known as the Shoulder Bone Shoulder Blade Wing Bone or Blade Bone is the Bone that connects the Humerus with the Clavicle. A scapula’s Posterior Surface is Crossed Obliquely by a Prominent Ridge the Spine which Divides the Bone into two Concave Areas The Supraspinous and Infraspinous Fossae. Your Shoulder Joint is a Ball-and-Socket Joint. The Head of the Humerus is the Ball and the Scapula forms the socket where the Humerus Sits.
The Humerus is the Long Bone in the upper arm. It is Located Between the below Joint and the Shoulder. The Humerus is the Longest and Largest Bone of the upper Limb. It Consists of a Proximal end a Shaft and a Distal end all which Contain Important Anatomical Landmarks.
The Body of The Radius is Compressed in a Craniocaudal direction and Slightly Curved in its Length. It Extends from the Lateral Side of the below to The Thumb Side of the Wrist and Runs Parallel to the Ulna. The Ulna is Usually Slightly Longer than the Radius the Radius is Thicker.
The Ulna is one of two Bones that make up the Forearm the other Being the Radius. It Forms the below Joint with the Uumerus and Also Articulates with the Radius both Proximally and Distally. The Ulna is a Long thin Bone with a Small Distal Head that Bears the Styloid Process and an Expanded Proximal end. The Proximal end Terminates in the Olecranon Process and Bears the Semilunar Notch on it’s Upper Surface.
The Carpal Bones are the Eight Small Bones that make up the carpus that Connects the Hand to the Forearm. The Term carpus is Derived from the Latin Carpus and the Greek karpós meaning “wrist”. In Human Anatomy the Main Role of the Wrist is to Facilitate Effective Positioning of the Hand and Powerful use of the Extensors and Flexors of the Forearm and the Mobility of Individual carpus Bones Increase the Freedom of Movements at the Wrist.
The Metacarpals form a Transverse arch to which the rigid row of distal Carpus Bones are Fixed. The Metacarpus of the Hand is Composed of Five Bony Structures Known as the Metacarpals. They Consist of a Proximal Base a Shaft and a Distal Head. Together they Function as the Part of the Skeleton which Scaffolds and Stabilizes the Palmar and Dorsal Regions of the Hand.
The bones of the fingers and of the toes. There are Five Proximal Phalanges which Correspond to Each of the Five fingers. Like the Metacarpal Bones the Proximal Phalanges have a Proximal Base with a Transverse Oval Articular Facet which Connects them to their Subsequent Metacarpal Bones Respectfully.
The Acromion of the Scapula is a Large Bony Projection on the Superior end of the Scapula. Together with the Coracoid Process it Extends Laterally over the Shoulder joint. The Acromion is a Continuation of the Scapular Spine.
Scapular Coracoid Grocess
The Coracoid Process is Located by Palpation. The Coracoid Process is a Hook-Shaped Bone Structure Projecting Anterolaterally from the Superior Aspect of the Scapular Neck. The Coracoid Process is a Thick Curved Process Attached by a Broad Base to the Upper Part of the Neck of the Scapula it Runs at first Upward and Medialward then Becoming Smaller.
Humeral Greater Tubercle
The Greater Tubercle of the Humerus is Situated Lateral to the Head of the Humerus and Posterolateral to the Lesser Tubercle. It Connects the Scapula and the two Bones of the Lower Arm the Radius and Ulna and Consists of three Sections. The Humeral Upper Extremity Consists of a Rounded Head.
Humeral Lesser tubercle
The Lesser Tubercle of the Humerus although Smaller The Proximal Aspect of the Humerus Articulates with the Glenoid Fossa of the Scapula Forming the Glenohumeral Joint. Distally at the Below Joint the Humerus Articulates with the Head of the Radius and Trochlear Notch of the Ulna.
Humeral Coronoid Fossa
The elbow is a trocho-gynglymoid joint with both rotatory and hinge components. It consists of articulations between the humerus, ulna and radius.Superior to the anterior portion of the trochlea is a small depression,
Because the Head of the radius is eccentric to the central axis of the Neck the Posterolateral aspect of the Radial Head comes into intimate contact with the capitellum during pronation, The common occurrence of an anterolateral fracture fragment.
Humeral Medial Epicondyle
The Humerus (plural) (humeri) is a Long Bone in the arm that runs from the Shoulder to the below / It connects the Scapula and the 2 Bones of theLlower arml. The (Radius) and (ulna) and consists of three sections.
The Trochlea of the Humerus is a Natural Bony Protrusion on the Anterior Distal Humerus in the intersection of three bones as Well as A (Joint In this Area) (Each the Ulna) the ( radius) and the Humerus have notches that fit with one another to aid in the Movement of the arm Figure.
Flexor Digitorum Sublimis
The Flexor Digitorum Superficialis FDS formerly known as the flexor digitorum sublimis is the largest of the Extrinsic Flexors of the forearm, It forms the Intermediate muscle layer Bet ween the Superficial and Deep Muscle Groups of the Forearm.
In Human Anatomy the Supinator is a (Broad Suscle) in the (Posterior compartment) of the forearm curved around the upper third of the radius, Its function is to ( supinate the forearm ).
The Styloid process is a Cylindrical Slender needle-like projection of Varying lengths averaging 2 to 3 cm. The styloid process projects from the inferior part of the petrous temporal bone and offers attachment to the stylohyoid ligament and the stylohyoid, stylopharyngeus, and styloglossus muscles.
