Radioulnar Joints Anatomy

The radius and ulna articulate at the proximal and distal radioulnar joints, which are synovial. At the proximal joint, the head of the radius articulates with the radial notch of the ulna (Fig. 3.88). The head and neck are encircled by the anular ligament, which attaches to the anterior and posterior margins of the notch on the ulna (Fig. 3.92) and blends with the capsule and radial collateral ligament of the elbow. Thus the cavity of the proximal joint is continuous with that of the elbow.

Skin Physiology : The Process Of Keratinization

Keratinization, also known as cornification, is unique to the epithelium of the skin. Keratinization of the human skin is of paramount importance; it allows humans to live on dry land. The process of keratinization begins in the basal layer of the epidermis and continues upward until full keratinization has occurred in the stratum corneum. The function and purpose of keratinization is to form the stratum corneum.

Anatomy, Normal Variations, and Relations of Stomach

The stomach is an enlarged reservoir of the proximal digestive tract, in which ingested food is soaked in gastric juice containing enzymes and hydrochloric acid and then released spasmodically into the duodenum by gastric peristalsis. The form and size of the stomach vary considerably, depending on the position of the body and the degree of filling.
