| macula of saccule | The oval neuroepithelial sensory receptor in the anterior wall of the saccule; hair cells of the neuroepithelium support the statoconial membrane and have terminal arborizations of vestibular nerve fibres around their bodies. Synonym: macula sacculi, saccular spot. (05 Mar 2000) |
|---|---|
| macula of utricle | The neuroepithelial sensory receptor in the inferolateral wall of the utricle; hair cells of the neuroepithelium support the statoconial membrane and have terminal arborizations of vestibular nerve fibres around their bodies; sensitive to linear acceleration in the longitudinal axis of the body and to gravitational influences. Synonym: macula utriculi, utricular spot. (05 Mar 2000) |
| macula pellucida | <gynaecology, physiology> The point where the graafian follicle is about to rupture on the surface of the ovary. Synonym: macula pellucida, stigma. (05 Mar 2000) |
| macula retinae | An oval area of the sensory retina, 3 by 5 mm, temporal to the optic disk corresponding to the posterior pole of the eye; at its centre is the central fovea, which contains only retinal cones. Synonym: area centralis, macula lutea, macular area, punctum luteum, Soemmerring's spot, yellow spot. (05 Mar 2000) |
| macula sacculi | The oval neuroepithelial sensory receptor in the anterior wall of the saccule; hair cells of the neuroepithelium support the statoconial membrane and have terminal arborizations of vestibular nerve fibres around their bodies. Synonym: macula sacculi, saccular spot. (05 Mar 2000) |
| macula tendinea | Gray-white or white, rounded or irregularly shaped, slightly opaque patches or spots that are sometimes observed postmortem in the epicardium, especially in middle-aged or older persons; they result from fibrous thickening, and sometimes hyalinization, of the epicardium; similar lesions may also occur in the visceral layer of the peritoneum. Synonym: macula lactea, macula tendinea, tache blanche, tache laiteuse, tendinous spot, white spot. (05 Mar 2000) |
| macula utriculi | The neuroepithelial sensory receptor in the inferolateral wall of the utricle; hair cells of the neuroepithelium support the statoconial membrane and have terminal arborizations of vestibular nerve fibres around their bodies; sensitive to linear acceleration in the longitudinal axis of the body and to gravitational influences. Synonym: macula utriculi, utricular spot. (05 Mar 2000) |
| mongolian macula | <dermatology> A benign bluish or bruised-appearing birthmark that is usually located on the lower back or buttocks. More common in dark-skinned races and may persist for months to years. (27 Sep 1997) |
| Saenger's macula | A spot of red brighter than the surrounding membrane, at the congested orifice of the duct of Bartholin's gland, sometimes seen in gonorrhoea. Synonym: Saenger's macula. (05 Mar 2000) |
| honeycomb macula | Oedema of the macular region of the retina. (05 Mar 2000) |
| neuroepithelium of macula | The specialised sensory hair cells of the epithelium of the macula sacculi and macula utriculi. Synonym: neuroepithelium maculae. (05 Mar 2000) |
| drusen of the macula | Excrescences of Bruch's membrane that produce a window in the retinal pigment epithelium and are a feature of age-related macular retinal degeneration. Synonym: macular drusen. (05 Mar 2000) |
| false macula | <ophthalmology> An extrafoveal point of fixation. (05 Mar 2000) |
| ganglion cells of retina | The nerve cell's of the retina whose central processes (fibres) form the optic nerve; their peripheral processes synapse with the bipolar cell's and through them with the rod and cone cell's; these cell bodies are round or flask-shaped and vary considerably in size. (05 Mar 2000) |
| ganglionic layer of retina | The intermediate layer of neurons in the retina composed largely of bipolar cells. Synonym: internal nuclear layer of retina, stratum ganglionare retinae, stratum nucleare internum retinae. (05 Mar 2000) |
