| rhombohedron | <geometry> A solid contained by six rhomboids; a parallelopiped. Origin: NL, fr. Gr. Rhomb + seat, base. Source: Websters Dictionary (01 Mar 1998) |
| rhomboid | <geometry> Quadangular, with the lateral angles obtuse. (23 Aug 1998) |
| rhomboid fossa | The floor of the fourth ventricle of the brain, formed by the ventricular surface of the rhombencephalon. Synonym: fossa rhomboidea. (05 Mar 2000) |
| rhomboid impression | <anatomy> An irregular pitted area on the inferior surface of the clavicle at its sternal end, giving attachment to the costoclavicular ligament. Synonym: impressio ligamenti costoclavicularis, costal tuberosity, rhomboid impression, tuberositas costalis. (05 Mar 2000) |
| rhomboid ligament | <anatomy> The ligament that connects the first rib and the clavicle near its sternal end; limits elavation of shoulder (at sternoclavicular joint). Synonym: ligamentum costoclaviculare, rhomboid ligament. (05 Mar 2000) |
| rhomboid minor | <anatomy, muscle> Origin, spinous processes of sixth and seventh cervical vertebrae; insertion, medial margin of scapula above spine; action, draws scapula toward vertebral column and slightly upward; nerve supply, dorsal nerve of scapula. Synonym: musculus rhomboideus minor, lesser rhomboid muscle. (05 Mar 2000) |
| rhomboideus | See: rhomboid minor muscle. (05 Mar 2000) |
| rhomboideus major | <anatomy, muscle> Origin, spinous processes and corresponding supraspinous ligaments of first four thoracic vertebrae; insertion, medial border of scapula below spine; action, draws scapula toward vertebral column; nerve supply, dorsal of scapula nerve. Synonym: musculus rhomboideus major, greater rhomboid muscle. (05 Mar 2000) |
| rhombomere | <cell biology, embryology> Neuromeres or segments in the hindbrain region that are of developmental significance. Shown to be lineage restriction units in that cells of adjacent rhombomeres do not mix with each other. Regulatory genes have been shown to be expressed in patterns in the developing hindbrain that relate to the neuromeric or segmentation pattern. (23 Aug 1998) |

| rhombencephalon |
The most caudal of the primary vesicles that are present in the early neural tube, which later gives rise to two secondary vesicles: metencephalon (prospective pons and cerebellum) and myelencephalon (prospective medulla oblongata).
