Osteology of Upper Limb

In this eLearning module, you will learn about Scapula. The scapula is also known as the shoulder blade, either of two large bones of the shoulder girdle in vertebrates. It is a flat triangular-shaped bone placed on the postero-lateral aspect of the thoracic cage. 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.

In this eLearning module, you will learn about Humerus. The humerus is the longest and largest bone of the upper limb. It articulates proximally with the glenoid via the glenohumeral (GH) joint and distally with the radius and ulna at the elbow joint. Just inferior to the head of the humerus is the anatomical neck of the humerus, which divides the head of the humerus from the greater and lesser tubercles.

In this eLearning module, you will learn about Clavicle. The clavicle, also referred to as the collar bone, is an elongated, S-shaped bone that sits between the shoulder and sternum at the top of the ribcage. The clavicle lies above several important nerves and blood vessels. The clavicle joins the scapula, or shoulder blade, and sternum to form two joints on either end of the bone.

In this eLearning module, you will learn about Introduction to Osteology. The framework of the body is built upon a series of bones, supplemented in certain regions by cartilage; the bony part of the framework constitutes the skeleton. In the skeleton of the adult there are 206 distinct bones. Bones are divisible into four classes, long, short, flat, and irregular.

In this eLearning module, you will learn about Radius. In this eLearning module, you will learn aboutThe radius is a long bone in the forearm. It lies laterally and parallel to ulna, the second of the forearm bones. The head of the radius is disk-shaped; its upper concave surface articulates with the humerus (upper arm bone) above, and the side surface articulates with the ulna. The radius and ulna pivot around one another to allow rotation of the wrist.

In this eLearning module, you will learn about Ulna. The ulna is one of two bones that make up the forearm. It lies medially and parallel to the radius, the second of the forearm bones. The upper end of the ulna presents a large C-shaped notch, the semilunar, or trochlear, notch, which articulates with the trochlea of the humerus (upper arm bone) to form the elbow joint. It is located in the medial forearm when the arm is in the anatomical position.

In this eLearning module, you will learn about Articulated Hand. A flexibility and support to the soft tissues is provided by the bones of the hands. These bones can be divided into three categories, carpal bones, metacarpals and phalenges. The hand is made up of 27 bones. The eight carpal bones make up the wrist. A set of eight irregularly shaped bones. It is located in the wrist area. There are five metacarpals and each one of them is related to a digit. There are three phalanges and each finger has three phalanges except for the thumb.
