| 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) |
| maculae acusticae | See: macula of saccule, macula of utricle. (05 Mar 2000) |
| macular | Maculate 1. Relating to or marked by macules. 2. Denoting the central retina, especially the macula retinae. (05 Mar 2000) |
| macular amyloidosis | A localised form of amyloidosis cutis characterised by pruritic symmetrical brown reticulated macules, especially on the upper back; microscopically, amyloid is deposited as small subepidermal globules. (05 Mar 2000) |
| macular area | 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) |
| macular arteries | See: inferior macular arteriole, superior macular arteriole. (05 Mar 2000) |
| macular atrophy | Atrophoderma in which the skin becomes bag like and wrinkled. Synonym: atrophia maculosa varioliformis cutis, atrophoderma maculatum, macular atrophy, primary idiopathic macular atrophy, primary macular atrophy of skin. Origin: G. Anetos, relaxed, + derma, skin (05 Mar 2000) |
| macular coloboma | A defect of the central retina as a result of arrested development or intrauterine retinal inflammation. (05 Mar 2000) |
| macular degeneration | <ophthalmology> Breakdown or damage to a portion of the retina known as the macula. Symptoms include blurring of vision (in central visual field), colours appear dim and difficulty reading or performing work up close. (27 Sep 1997) |
