| anterior pole of eyeball | The centre of the corneal curvature of the eye. Synonym: polus anterior bulbi oculi. (05 Mar 2000) |
|---|---|
| check ligaments of eyeball | <anatomy> Medial and lateral, expansions of the sheaths of the medial and lateral rectus muscles of the eyeball which are attached, respectively, to the lacrimal bone and to the orbital tubercle of the zygomatic bone; they serve to prevent overaction of these muscles. (05 Mar 2000) |
| muscles of eyeball | The voluntary muscles which control eye movement (27 Sep 1997) |
| posterior pole of eyeball | The centre of the posterior curvature of the eye. Synonym: polus posterior bulbi oculi. (05 Mar 2000) |
| posterior segment of eyeball | The large space between the lens and the retina; it is filled with the vitreous body. Synonym: camera vitrea bulbi, vitreous camera, vitreous chamber of eye. (05 Mar 2000) |
| sheath of eyeball | A condensation of connective tissue on the outer aspect of the sclera from which it is separated by a narrow cleftlike episcleral space; the sheath is attached to the sclera near the sclerocorneal junction and blends with the fascia of the extraocular muscles. Synonym: vagina bulbi, capsula bulbi, eye capsule, fascia bulbi, sheath of eyeball, Tenon's capsule, vagina oculi. (05 Mar 2000) |
| nervous tunic of eyeball | Light sensitive layer of the eye. In vertebrates, looking from outside, there are four major cell layers: (i) the outer neural retina, which contains neurons (ganglion cells, amacrine cells, bipolar cells) as well as blood vessels, (ii) the photoreceptor layer, a single layer of rods and cones, (iii) the pigmented retinal epithelium (PRE or RPE), (iv) the choroid, composed of connective tissue, fibroblasts and including a well vascularised layer, the chorio capillaris, underlying the basal lamina of the PRE. Behind the choroid is the sclera, a thick organ capsule. In molluscs (especially cephalopods such as the squid) the retina has the light sensitive cells as the outer layer with the neural and supporting tissues below. See: retinal rods, retinal cones, rhodopsin. (18 Nov 1997) |
| suspensory ligament of eyeball | A thickening of the inferior part of the bulbar sheath which supports the eye within the orbit; it extends between the lateral and medial orbital margins and includes the medial and lateral check ligament's. Synonym: Lockwood's ligament. (05 Mar 2000) |
| equator of eyeball | An imaginary line encircling the globe of the eye equidistant from the anterior and posterior poles. Synonym: equator bulbi oculi. (05 Mar 2000) |
| eyeball | The eye proper without the appendages. Synonym: bulbus oculi, bulb of eye, globe of eye. (05 Mar 2000) |
| eyeball compression reflex | Slowing of the heart rate due to the vagal effects of compressing an eyeball. Synonym: eyeball compression reflex. (05 Mar 2000) |
| eyeball-heart reflex | Slowing of the heart rate due to the vagal effects of compressing an eyeball. Synonym: eyeball compression reflex. (05 Mar 2000) |
| fascial sheath of eyeball | A condensation of connective tissue on the outer aspect of the sclera from which it is separated by a narrow cleftlike episcleral space; the sheath is attached to the sclera near the sclerocorneal junction and blends with the fascia of the extraocular muscles. Synonym: vagina bulbi, capsula bulbi, eye capsule, fascia bulbi, sheath of eyeball, Tenon's capsule, vagina oculi. (05 Mar 2000) |
| abnormal heart chamber dimensions | <radiology> Left ventricular volume overload, left ventricular hypertrophy, right ventricular volume overload, right ventricular hypertrophy, fixed subvalvular aortic stenosis, hypoplastic left/right ventricle; common ventricle, congestive cardiomyopathy (12 Dec 1998) |
| air chamber | 1. A chamber or cavity filled with air, in an animal or plant. 2. A cavity containing air to act as a spring for equalizing the flow of a liquid in a pump or other hydraulic machine. Source: Websters Dictionary (01 Mar 1998) |
