| lateral diffusion | Diffusion in two dimensions, usually referring to movement in the plane of the membrane, such as the motion of fluorescently labelled lipids or proteins measured by the technique of fluorescent recovery after photobleaching (FRAP). (18 Nov 1997) |
|---|---|
| lateral direct veins | One or more veins running a subependymal course in a coronal plane over the thalamus, terminating in the internal cerebral vein. Synonym: lateral direct veins, surface thalamic veins. (05 Mar 2000) |
| lateral epicondylar crest | The distal sharp portion of the lateral margin of the humerus. Synonym: crista supracondylaris lateralis, lateral epicondylar crest, lateral epicondylar ridge, lateral supracondylar crest. (05 Mar 2000) |
| lateral epicondylar ridge | The distal sharp portion of the lateral margin of the humerus. Synonym: crista supracondylaris lateralis, lateral epicondylar crest, lateral epicondylar ridge, lateral supracondylar crest. (05 Mar 2000) |
| lateral epicondyle | A bony prominence of the outer aspect of the humerus. The lateral epicondyle provides origin for the muscles which dorsiflex the wrist. Inflammation at this site is known as tennis elbow. (27 Sep 1997) |
| lateral epicondyle of femur | The epicondylus located proximal to the lateral condyle. Synonym: epicondylus lateralis ossis femoris, lateral femoral tuberosity. (05 Mar 2000) |
| lateral epicondyle of humerus | The epicondylus situated at the lateral side of the distal end of the bone. Synonym: epicondylus lateralis humeri. (05 Mar 2000) |
| lateral epicondylitis | <pathology> Inflammation at the lateral epicondyle (bony process off the humerus) of the elbow and the tendons that insert there. It has earned the name tennis elbow because of the common occurrence of this condition in tennis players (constant dorsiflexion of the wrist). See: medial epicondylitis. (27 Sep 1997) |
| lateral excursion | Movement of the mandible to the right or left side. (05 Mar 2000) |
| lateral femoral circumflex artery | <anatomy, artery> Origin, profunda femoris; distribution, hip joint, thigh muscles; anastomoses, medial circumflex femoral, inferior gluteal, superior gluteal. Synonym: arteria circumflexa femoris lateralis, lateral circumflex artery of thigh, lateral femoral circumflex artery. (05 Mar 2000) |
| lateral femoral tuberosity | The epicondylus located proximal to the lateral condyle. Synonym: epicondylus lateralis ossis femoris, lateral femoral tuberosity. (05 Mar 2000) |
| lateral fillet | A bundle of ascending fibres that originate from the cochlear and auditory relay nuclei of the rhombencephalon, enter the trapezoid body, a transverse fibre stratum in which about half their number decussate, and from here turn rostrally along the lateral side of the spinothalamic tract; in the midbrain, it arches dorsally and enters the inferior colliculus in which all of its fibres terminate; the auditory pathway is transsynaptically extended from here by the brachium of the inferior colliculus to the medial geniculate body of the thalamus, from which in turn the auditory radiation leads to the auditory cortex; intercalated in the trapezoid body and along the ascending trajectory of the lemniscus are several cell groups in which part of the fibres synapse. Synonym: lemniscus lateralis, acoustic lemniscus, auditory lemniscus, auditory tract, lateral fillet. (05 Mar 2000) |
| lateral folds | Ventral foldings of the lateral margins of the embryonic disk, the development of which establishes the definitive embryonic body form. (05 Mar 2000) |
| lateral fossa of brain | The deep depression of the basal surface of the forebrain that corresponds in position to the anterior perforated substance. Bounded medially by the optic tract and rostrally by the orbital surface of the frontal lobe, it extends laterally around the overhanging pole of the temporal lobe into the Sylvian fissure (sulcus lateralis). Synonym: fossa lateralis cerebri, fossa of Sylvius, lateral fossa of brain, vallecula sylvii. (05 Mar 2000) |
| lateral frontobasal artery | <anatomy, artery> A branch of the insular part of the middle cerebral artery distributed to the cortex of the lateral, inferior part of the frontal lobe. Synonym: arteria frontobasalis lateralis, ramus orbitofrontalis lateralis, lateral orbitofrontal branch, orbitofrontal artery. (05 Mar 2000) |
