| pes hippocampi | <anatomy> The anterior thickened extremity of the hippocampus. Synonym: pes hippocampi, digitationes hippocampi. (05 Mar 2000) |
|---|
| alveus hippocampi | A thin white band of fornix fibres covering the ventricular surface of the hippocampus. Synonym: alveus hippocampi. (05 Mar 2000) |
|---|---|
| rudimentum hippocampi | A thin layer of gray matter on the dorsal surface of the corpus callosum in which the medial and lateral longitudinal stria lie embedded. The indusium griseum is a rudimentary component of the hippocampus, continuous caudally around the splenium of the corpus callosum with the fasciolar gyrus, a slender convolution in turn continuous with the dentate gyrus of the hippocampus; rostrally the indusium griseum curves around the genu and rostrum of corpus callosum and extends ventralward to the olfactory trigone as the tenia tecta or rudimentum hippocampi, hidden in the depth of the posterior parolfactory sulcus that marks the anterior border of the subcallosal gyrus or precommissural septum. Synonym: supracallosal gyrus. (05 Mar 2000) |
| commissura hippocampi | The triangular subcallosal plate of commissural fibres resulting from the converging of the right and left fornix bundles which exchange numerous fibres and which curve back in the contralateral fornix to end in the hippocampus of the opposite side. Synonym: commissura hippocampi, commissure of fornix, delta fornicis, hippocampal commissure, psalterium, transverse fornix. (05 Mar 2000) |
| sulcus hippocampi | A shallow groove between the dentate gyrus and the parahippocampal gyrus; the remains of a fissure extending deep into the hippocampus between Ammon's horn and the dentate gyrus which becomes obliterated during foetal development. Synonym: sulcus hippocampi, dentate fissure, fissura dentata, fissura hippocampi, hippocampal fissure. (05 Mar 2000) |
| digitationes hippocampi | Synonym: foot of hippocampus. Origin: Mod. L. Pl. Of digitatio (05 Mar 2000) |
| tenia hippocampi | A narrow sharp-edged crest of white fibre matter, continuous with the alveus hippocampi, attached to the medial border of the hippocampus; composed of efferent fibres of the hippocampus that form the fornix, fibres of the hippocampal commissure, and septohippocampal fibres. Synonym: corpus fimbriatum, tenia hippocampi. (05 Mar 2000) |
| fascia dentata hippocampi | Serrated strip of gray matter under the medial border of the hippocampus and in its depths. It is an archicortex which develops along the edge of the hippocampal fissure and which consists of molecular, granular, and polymorphic layers. The molecular layer is continuous with that of the hippocampus in the depths of the hippocampal fissure. (carpenter and sutin, human neuroanatomy, 8th ed, p626) (12 Dec 1998) |
| fimbria hippocampi | A narrow sharp-edged crest of white fibre matter, continuous with the alveus hippocampi, attached to the medial border of the hippocampus; composed of efferent fibres of the hippocampus that form the fornix, fibres of the hippocampal commissure, and septohippocampal fibres. Synonym: corpus fimbriatum, tenia hippocampi. (05 Mar 2000) |
| fissura hippocampi | A shallow groove between the dentate gyrus and the parahippocampal gyrus; the remains of a fissure extending deep into the hippocampus between Ammon's horn and the dentate gyrus which becomes obliterated during foetal development. Synonym: sulcus hippocampi, dentate fissure, fissura dentata, fissura hippocampi, hippocampal fissure. (05 Mar 2000) |
| pes | Origin: L, the foot. <anatomy> The distal segment of the hind limb of vertebrates, including the tarsus and foot. Source: Websters Dictionary (01 Mar 1998) |
| pes abductus | Permanent eversion of the foot, the inner side alone of the sole resting on the ground; it is usually combined with a breaking down of the plantar arch. Synonym: pes abductus, pes pronatus, pes valgus. (05 Mar 2000) |
| pes adductus | Inversion of the foot, the outer side of the sole only touching the ground; usually some degree of talipes equinus is associated with it, and often talipes cavus. Synonym: pes adductus, pes varus. (05 Mar 2000) |
| pes anserinus | <anatomy, nerve> The diverging branches of the facial nerve passing through the substance of the parotid gland, connected by numerous looped anastomoses. Synonym: plexus intraparotideus, pes anserinus. (05 Mar 2000) |
| pes cavus | Literally a hollow foot, pes cavus is a foot with too high an arch. (12 Dec 1998) |
| pes equinovalgus | Talipes equinus and talipes valgus combined; the foot is plantarflexed, everted, and abducted. See: clubfoot. Synonym: equinovalgus, pes equinovalgus. (05 Mar 2000) |
