| traumatic gastritis | A condition of cattle, caused by the penetration of the stomach wall, usually the reticulum, by any kind of sharp object (usually metallic) which has been swallowed. Synonym: hardware disease, traumatic reticuloperitonitis. (05 Mar 2000) |
| eosinophilic gastritis | <radiology> Eosinophilic infiltration of mucosa, submucosa, and muscularis of small bowel with or without stomach, stomach (almost always limited to antrum): enlarged gastric rugae, cobblestone nodules, polyps (=mucosal type), rigid wall with narrowed antrum/pylorus, bulky inramural mass up to 9 cm (=muscular type), wet stomach, ulcers rare, may have ascites, small bowel (predominantly jejunum), thickening and distortion of folds (=mucosal type), effacement of mucosa and narrowing of lumen (=muscular type), prognosis: tendency to spontaneous remission, treatment: steroids; removal of sensitizing agent (12 Dec 1998) |
| erosive gastritis | <gastroenterology> A form of severe inflammation of the stomach that can result in erosions in the lining of the stomach. Complications include perforation, penetration (into a surrounding organ) and haemorrhage. (27 Sep 1997) |

| medial crus of the superficial inguinal ring | Portion of the external oblique aponeurosis which passes medial to the superficial inguinal ring forming the medial boundary of the ring. Synonym: crus mediale annuli inguinalis superficialis. (05 Mar 2000) |
| membranous layer of superficial fascia | The membranous layer of the subcutaneous tissue in the urogenital region attaching posteriorly to the border of the urogenital diaphragm, at the sides to the ischiopubic rami, and continuing anteriorly onto the abdominal wall. Synonym: fascia perinei superficialis, Colles' fascia, Cruveilhier's fascia, membranous layer of superficial fascia. (05 Mar 2000) |
| greater superficial petrosal nerve | <anatomy, nerve> The parasympathetic root of the pterygopalatine ganglion; a branch from the genu of the facial nerve exiting via the hiatus of the facial canal and running in a groove on the anterior surface of the petrous part of the temporal bone beside the foramen lacerum to join the deep petrosal nerve, thus forming the nerve of the pterygoid canal, which passes through the pterygoid canal to reach the pterygopalatine ganglion. Synonym: nervus petrosus major, greater petrosal nerve. (05 Mar 2000) |
| polymorphic superficial keratitis | Epithelial degeneration occurring in starvation. (05 Mar 2000) |
| superficial | 1. Cursory; not thorough. 2. Pertaining to or situated near the surface. Synonym: superficialis. Origin: L. Superficialis, fr. Superficies, surface (05 Mar 2000) |
| superficial angioma | <dermatology> Red or purple-coloured vascular skin markings that develop shortly after birth. Most are usually painless and benign and sharply demarcated from surrounding skin, usually located on the head and neck, and grow rapidly. It is caused by proliferation of immature capillary vessels in active stroma, and is usually present at birth or occurs within the first two or three months of life. Some lesions (cavernous haemangioma) will disappear or become harder to see as the child approaches school age. Localised steroid injections have been used successfully to reduce the size of a birthmark but generally they undergo spontaneous regression and involution without scarring and normally require no treatment.

| superficial back muscles | Muscles originating from the vertebral column and having their fleshy bellies located in the back, but inserting onto the appendicular skeleton of the upper limb or the ribs. They are not innervated by dorsal primary rami of spinal nerves, as are the deep or true muscles of the back; includes the trapezius muscle (innervated by spinal accessory nerve) and latissimus dorsi, rhomboids, levator scapulae, and thoracic muscles (innervated by ventral primary rami of spinal nerves, or derivatives thereof).
