The organs of sight are a duo of eyes inwards human. The eyes are situated inwards deep protective bony cavities, called the orbits or oculus sockets of the skull. The written report of structure, component together with diseases of the oculus is called ophthalmology.
The lens together with suspensory ligament split the cavity of the eyeball into 2 chambers: the anterior minor aqueous bedroom together with the posterior large vitreous chamber. The aqueous bedroom itself consists of 2 cavities: large anterior inwards front end of the iris together with behind cornea together with minor posterior betwixt the iris together with the lens. Both the parts of aqueous bedroom filled amongst a clear, watery fluid, the aqueous humour. The vitreous bedroom (the largest chamber) is sum of thick, transparent, jelly similar substance, the vitreous sense of humor or vitreous body. The latter consists of H2O , poly peptide vitrein, hyaluronic acid together with collagen fibres. It is obviously secreted yesteryear the retina during evolution of the eye.
Aqueous Humour vs Vitreous Humour
Aqueous humour | Vitreous humour |
It occurs inwards aqueous chamber | It occurs inwards vitreous chamber |
It is a watery fluid | It is a jelly similar substance |
It is secreted yesteryear ciliary processes | It is apparently secreted yesteryear retina during evolution of eye. |
It is continuously absorbed into blood together with replaced. | It is absorbed or replaced. |
It contains nearly of the diffusible substances of the plasma | It consists of H2O (90%), poly peptide vitrein, hyaluronic acid together with collagen fibres. |
Obstruction inwards its period of time may harm retina yesteryear increasing intraocular pressure | It does non flow. |
Maintains the cast of the cornea together with render nutrition to both lens together with cornea. | Maintains the cast of the oculus ball together with contribute to intraocular pressure level together with besides to the focussing of lite on the retina. |
