| groove for inferior venae cava | A groove on the posterior surface of the liver between the caudate lobe and the right lobe which gives passage to the inferior vena cava. Synonym: sulcus venae cavae, fossa venae cavae, sulcus for vena cava. (05 Mar 2000) |

| gyrus frontalis inferior | A broad convolution on the convexity of the frontal lobe of the cerebrum between the inferior frontal sulcus and the sylvian fissure; divided by branches of the sylvian fissure into three parts: pars (opercularis) basilaris, triangular part, and orbital part; the first two constitute a portion of the frontal operculum. Synonym: gyrus frontalis inferior, inferior frontal convolution. (05 Mar 2000) |
| gyrus temporalis inferior | A sagittal convolution on the inferolateral border of the temporal lobe of the cerebrum, separated from the middle temporal gyrus by the inferior temporal sulcus. On the inferior surface of the temporal lobe it is separated from the medial occipitotemporal gyrus by the occipitotemporal sulcus. It includes the lateral occipitotemporal gyrus. Synonym: gyrus temporalis inferior, inferior temporal convolution, third temporal convolution. (05 Mar 2000) |
| colliculus inferior | The ovoid, paired, inferior eminence of the laminae of mesencephalic tectum; it receives the lateral lemniscus and projects by way of the brachium of inferior colliculus to the medial geniculate body of the thalamus, and is thus an essential way-station in the central auditory pathway. Synonym: colliculus inferior, corpus quadrigeminum posterius, inferior nasal colliculus, posterior quadrigeminal body. (05 Mar 2000) |
| commissure of inferior colliculi | Nerve fibres on the midline between the two inferior colliculi connecting the colliculi and containing some fibres originating from nontectal nuclei. (05 Mar 2000) |
| concha nasalis inferior | A thin, spongy, bony plate with curved margins, on the lateral wall of the nasal cavity, separating the middle from the inferior meatus; it articulates with the ethmoid, lacrimal, maxilla, and palate bones, the above bony plate and its thick mucoperiosteum containing an extensive cavernous vascular bed for heat exchange. Synonym: concha nasalis inferior, inferior turbinated bone, turbinated body. (05 Mar 2000) |
| plexus dentalis inferior | Formed by branches of the inferior alveolar nerve interlacing before they supply the teeth; it gives off interior dental branches to the teeth and inferior gingival branches to the gums. Synonym: plexus dentalis inferior. (05 Mar 2000) |
| plexus hypogastricus inferior | One of the bilateral autonomic plexus in the pelvis distributed to the pelvic viscera; it receives the hypogastric nerves and the pelvic splanchnic nerves. Synonym: plexus hypogastricus inferior, plexus pelvinus, pelvic plexus. (05 Mar 2000) |
| plexus mesentericus inferior | An autonomic plexus, derived from the abdominal aortic plexus, surrounding the inferior mesenteric artery and sending branches to the descending colon, sigmoid, and rectum. Synonym: plexus mesentericus inferior. (05 Mar 2000) |
| plexus thyroideus inferior | An autonomic plexus on the artery of this name, derived from the subclavian plexus. Synonym: plexus thyroideus inferior. (05 Mar 2000) |
| plexus vesicalis inferior | A venous plexus in the female corresponding to the prostatic venous plexus in the male. Synonym: plexus vesicalis inferior. (05 Mar 2000) |
| plica duodenalis inferior | A fold of peritoneum bounding the inferior duodenal recess. Synonym: plica duodenalis inferior, plica duodenomesocolica, duodenomesocolic fold. (05 Mar 2000) |
| musculus constrictor pharyngis inferior | Origin, outer surfaces of thyroid (thyropharyngeal part) and cricoid (cricopharyngeal part, musculus cricopharyngeus; superior or upper oesophageal sphincter muscle) cartilages; insertion, pharyngeal raphe in the posterior portion of wall of pharynx; action, narrows lower part of pharynx in swallowing, the cricopharyngeal part has a sphincteric function for the oesophagus, allowing some voluntary control of eructation and reflux; nerve supply, pharyngeal plexus. Synonym: musculus constrictor pharyngis inferior, cricopharyngeus muscle, laryngopharyngeus, musculus laryngopharyngeus. (05 Mar 2000) |
| musculus gemellus inferior | <anatomy, muscle> Origin, tuberosity of ischium; insertion, tendon of musculus obturator internus; action, rotates thigh laterally; nerve supply, sacral plexus. Synonym: musculus gemellus inferior, gemellus. (05 Mar 2000) |
| musculus longitudinalis inferior | An intrinsic muscle of the tongue, cylindrical in shape, occupying the underpart on either side; action, shortens the lower part of the tongue; nerve supply, motor by hypoglossal, sensory by lingual. Synonym: musculus longitudinalis inferior, inferior lingual muscle. (05 Mar 2000) |
