| 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 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) |
| albedo retinae | An obsolete term for a white area of the retina due to oedema or infarction. (05 Mar 2000) |
| arteria centralis retinae | A branch of the ophthalmic artery which penetrates the optic nerve 1 cm behind the eye to enter the eye at the optic papilla in the retina; it divides into superior and inferior temporal and nasal branches. Synonym: arteria centralis retinae, arteria retinae centralis, Zinn's artery. (05 Mar 2000) |
| arteria retinae centralis | A branch of the ophthalmic artery which penetrates the optic nerve 1 cm behind the eye to enter the eye at the optic papilla in the retina; it divides into superior and inferior temporal and nasal branches. Synonym: arteria centralis retinae, arteria retinae centralis, Zinn's artery. (05 Mar 2000) |
