| medial longitudinal bundle | A longitudinal bundle of fibres extending from the upper border of the mesencephalon into the cervical segments of the spinal cord, located close to the midline and ventral to the central gray matter; it is composed largely of fibres from the vestibular nuclei ascending to the motor neurons innervating the external eye muscles (abducens, trochlear, and oculomotor nuclei), and descending to spinal cord segments innervating the musculature of the neck. Synonym: fasciculus longitudinalis medialis, Collier's tract, medial longitudinal bundle, posterior longitudinal bundle. (05 Mar 2000) |

| medial longitudinal stria | A thin longitudinal band of nerve fibres accompanied by gray matter, running along the surface of the corpus callosum on either side of the median line. Together with the lateral longitudinal stria it forms part of a thin layer of gray matter on the dorsal surface of the corpus callosum, the indusium griseum, a rudimentary component of the hippocampus. Synonym: stria longitudinalis medialis. (05 Mar 2000) |
| medial lumbar intertransversarii muscles | Origin, accessory and mamillary processes of lumbar vertebrae; insertion, corresponding processes of next superior vertebra; action, abducts lumbar vertebrae; nerve supply, dorsal primary rami of lumbar spinal nerves. Synonym: musculi intertransversarii mediales lumborum, medial lumbar intertransverse muscles. (05 Mar 2000) |

| medial lumbocostal arch | <anatomy> One of Haller's arches; a tendinous thickening of the psoas fascia that extends from the body of the first lumbar vertebra to its transverse process on either side. A portion of the diaphragm arises from it. Synonym: ligamentum arcuatum mediale, arcus lumbocostalis medialis, medial lumbocostal arch. (05 Mar 2000) |

| medial mammary branches | Branches primarily distributed to the medial portion of the breast. Nomina Anatomica lists medial mammary branches (rami mammarii mediales...) of the following: 1) anterior cutaneous branches of ventral primary rami of thoracic spinal nerves (...rami cutanei anterioris ramorum ventralium nervorum thoracicorum; also known as anterior cutaneous branches of intercostal nerves (...rami cutanei anterioris nervorum intercostalium); nerve branches accompanying the perforating branches of internal thoracic artery. 2) perforating branches of internal thoracic artery (...rami perforantes arteriae thoracicae internae ). Synonym: rami mammarii mediales. (05 Mar 2000) |
| medial margin | The border of a structure closest to the medial plane. Synonym: margo medialis, medial margin. (05 Mar 2000) |

| medial meniscus | <anatomy> A flat disc-shaped ligament which stabilises and supports the inner aspect of the knee joint. Commonly injured in knee sprains. (27 Sep 1997) |
| medial midpalmar space | The more medial of the central palmar spaces, bounded medially by the hypothenar compartment; related distally to the synovial tendon sheaths of digits 3 and 4 and proximally to the common flexor sheath. Synonym: medial midpalmar space, middle palmar space. (05 Mar 2000) |
| medial nasal branches of anterior ethmoidal nerve | <anatomy, nerve> Branches of nasociliary nerve distributed to the nasal septum. Synonym: rami nasales mediales nervi ethmoidalis anterioris. (05 Mar 2000) |
