Abstract:
1. Scaphoid bone is the largest and clinically most significant bone in the proximal row of the carpal bones. It consists of three sections: proximal and distal pole and scaphoid waist. Extension and radial duction of the hand results in overloading of distal pole of scaphoid and its waist. 2. Nutrient arteries (from radial artery) enter the bone predominantly from the dorsal surface (75%). Functional intraosseous anastomoses do not exist. In 33% of cases proximal scaphoid has no separate nutrient arteries. 3. Scaphoid bone develops from two centres; however, two separate ossification nuclei are quite rare. Non-union of both centres during the early ontogenetic development results in os scaphoideum bipartitum congenitum.

The pectoralis major has two origins. Its clavicular head originates on the medial half of the clavicle. In contrast, the sternocostal head originates on the costal cartilages of ribs 1-6, the sternum, and the aponeurosis of the external oblique of the...
Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses or amphiarthroses, whereas all synovial joints are classified as diarthroses.
