| lesser tubercle of humerus | The anterior of the two tubercles of the neck of the humerus on which the subscapularis is inserted. Synonym: tuberculum minus humeri, lesser tuberosity of humerus. (05 Mar 2000) |

| lesser tuberosity of humerus | The anterior of the two tubercles of the neck of the humerus on which the subscapularis is inserted. Synonym: tuberculum minus humeri, lesser tuberosity of humerus. (05 Mar 2000) |
| lesser tympanic spine | The posterior edge of the tympanic notch (of Rivinus). Synonym: spina tympanica minor. (05 Mar 2000) |
| lesser vestibular glands | A number of minute mucous glands opening on the surface of the vestibule between the orifices of the vagina and urethra. Synonym: glandulae vestibulares minores. (05 Mar 2000) |
| lesser wing of sphenoid bone | One of a bilateral pair of triangular, pointed plates extending laterally from the anterolateral body of the sphenoid bone. Forming the posteriormost portion of the floor of the anterior cranial fossa, their sharp posterior edge forms the sphenoidal ridge separating anterior and middle cranial fossae. The medial end of the lesser wing attaches to the body by means of two pedicles, thus forming the optic canal. The wing itself forms the superior margin of the supraorbital fissure. Synonym: ala minor ossis sphenoidalis, ala orbitalis, Ingrassia's apophysis, Ingrassia's wing. (05 Mar 2000) |
| lesser zygomatic muscle | <anatomy, muscle> Origin, zygomatic bone posterior to zygomaticomaxillary suture; insertion, orbicularis oris of upper lip; action, draws upper lip upward and outward; nerve supply, facial. Synonym: musculus zygomaticus minor, caput zygomaticum quadrati labii superioris, lesser zygomatic muscle. (05 Mar 2000) |
| communicating branches of auriculotemporal nerve to facial nerve | <anatomy, nerve> Branches conveying fibres from the auriculotemporal nerve to the facial nerve. Synonym: rami communicantes nervi auriculotemporalis cum nervo faciali. (05 Mar 2000) |
| communicating branches of lingual nerve to hypoglossal nerve | <anatomy, nerve> Communicating branches between the lingual nerve (from mandibular nerve) and hypoglossal nerve forming a plexus on the hypoglossus muscle. Synonym: rami communicantes nervi lingualis cum nervo hypoglosso. (05 Mar 2000) |
| acute renal failure | <nephrology> A sudden decline in renal function may be triggered by a number of acute disease processes. Examples include sepsis (infection), shock, trauma, kidney stones, kidney infection, drug toxicity (aspirin or lithium), poisons or toxins (drug abuse) or after injection with an iodinated contrast dye (adverse effect). Chronic renal failure represents a slow decline in kidney function over time. Chronic renal failure may be caused by a number of disorders which include long-standing hypertension, diabetes, congestive heart failure, lupus or sickle cell anaemia. Both forms of renal failure result in a life-threatening metabolic derangement. (27 Sep 1997) |
| aminoaciduria, renal | Impairment of renal tubular transport of amino acids. (12 Dec 1998) |
| back-pressure renal atrophy | <radiology> Caliectasis without obstruction, due to repeated episodes of obstruction, gradual loss of renal pyramids (12 Dec 1998) |
| base of renal pyramid | The outer broad part of a renal pyramid that lies next to the cortex. Synonym: basis pyramidis renis. (05 Mar 2000) |
| branchio-oto-renal syndrome | <syndrome> An autosomal dominant disorder manifested by various combinations of preauricular pits, branchial fistulae or cysts, lacrimal duct stenosis, hearing loss, structural defects of the outer, middle, or inner ear, and renal dysplasia. Associated defects include asthenic habitus, long narrow facies, constricted palate, deep overbite, and myopia. Hearing loss may be due to mondini type cochlear defect and stapes fixation. (12 Dec 1998) |
| capsular branches of renal artery | <anatomy, artery> Branches arising from the renal artery outside of the kidney that are distributed to the renal capsule. Synonym: rami capsulares arteriae renalis. (05 Mar 2000) |
| captopril renal scan | <radiology> In a kidney with a lesion in the afferent arteriole (e.g. Atherosclerotic plaque), reflex constriction of the efferent arteriole occurs through angiotensin system thus maintaining renal perfusion. ACE inhibition prevents constriction of efferent arteriole. Therefore, perfusion is decreased to a kidney with afferent lesions and the renal scan to looks WORSE. Bottom line: renal scans appear WORSE with captopril administration if there is a lesion in the afferent arteriole. See: renal artery stenosis (12 Dec 1998) |
