| intermediate hypothalamic region | The infundibular portion of the hypothalamus, includes the medial tuberal nuclei and portions of the dorsomedial, ventromedial, arcuate (infundibular), posterior and lateral hypothalamic nuclei; located internally in the general area of the infundibulum. (05 Mar 2000) |
| intermediate image plane | <microscopy> In a light microscope, the plane into which the objective lens directly focuses the image of the specimen. The plane is usually located a set distance (commonly 10 mm) below the shoulder for the ocular and another fixed distance (generally 160 mm) behind the rear focal plane of the objective lens. The ocular forms a virtual image of the intermediate image for visual observation, or projects a real image for photography and video microscopy. Note: The objective lens, combined with the coverslip of proper thickness, is corrected for projecting the primary image to the specified intermediate image plane only. (05 Aug 1998) |
| intermediate junction | <cell biology> Specialised intercellular junction in which the membranes are separated by 15-25nm and into which are inserted microfilaments. Similar in structure to two apposed focal adhesions, though this may be misleading. Microfilaments inserted into the zonula adherens may interact (via myosin) with other microfilaments to generate contraction. Constitute mechanical coupling between cells. (18 Nov 1997) |
| intermediate lacunar lymph node | A lymph node of the external iliac group located between the external iliac artery and vein at the vascular lacuna. Synonym: nodus lacunaris intermedius, intermediate lacunar node. (05 Mar 2000) |
| intermediate lacunar node | A lymph node of the external iliac group located between the external iliac artery and vein at the vascular lacuna. Synonym: nodus lacunaris intermedius, intermediate lacunar node. (05 Mar 2000) |
| intermediate lamella | One of the lamellae of partially resorbed osteons occurring between newer, complete osteons. Synonym: ground lamella, intermediary system, intermediate lamella. (05 Mar 2000) |
| intermediate laryngeal cavity | Portion of the cavity of the larynx between the vestibular and vocal folds, with which the ventricles communicate. Synonym: aditus glottidis superior. (05 Mar 2000) |
| intermediate layer | The nuclear zone of the developing neural tube between the marginal layer and the ependymal layer; forms the gray matter of the central nervous system. Synonym: intermediate layer, mantle zone. (05 Mar 2000) |
| intermediate layer of the transversospinalis muscles | <anatomy, muscle> Origin, from the sacrum, sacroiliac ligament, mamillary processes of the lumbar vertebrae, transverse processes of thoracic vertebrae, and articular processes of last four cervical vertebrae; insertion, into the spinous processes of all the vertebrae up to and including the axis; action, rotates vertebral column; nerve supply, dorsal primary rami of spinal nerves. Synonym: musculus multifidus, intermediate layer of the transversospinalis muscles, musculus multifidus spinae. (05 Mar 2000) |
| intermediate line of iliac crest | The line on the crest of the ilium between the outer and inner lips, for origin of internal oblique muscle. Synonym: linea intermedia cristae iliacae. (05 Mar 2000) |
| intermediate lumbar lymph nodes | The chain of lymph nodes located between the aorta and the inferior vena cava. Synonym: nodi lymphatici lumbales intermedii, lumbar lymph nodes. (05 Mar 2000) |
| intermediate mass | The variable connection between the two thalamic masses across the third ventricle; absent in about 20% of human brains. Synonym: adhesio interthalamica, commissura cinerea, commissura grisea, intermediate mass, massa intermedia. (05 Mar 2000) |
| intermediate mesoderm | A continuous band of mesoderm between the segmented paraxial mesoderm medially and the lateral plate mesoderm laterally; from it develops the nephrogenic cord. (05 Mar 2000) |
| intermediate nerve | A root of the facial nerve containing sensory fibres for taste from the anterior 2/3 of tongue whose cell bodies are located in the geniculate ganglion and presynaptic parasympathetic autonomic fibres whose cell bodies are located in the superior salivatory nucleus, i.e., the fibres eventually conveyed via the chorda tympani branch of the facial nerve to the lingual nerve. Synonym: intermediary nerve, intermediate nerve, portio intermedia, Wrisberg's nerve. (05 Mar 2000) |
