Week 9 Flashcards
what is the ciliary body in
uvea
what are the properties of ciliary body
pigmented
triangular shape
what is the ciliary body seperated into
pars plana = flat part
pars plicata = pleated part
what are the layers of ciliary body
superciliaris
stroma
3 types of muscle
longitudinal fibers
radial fibres
circular fibers
how is the ciliary body adapted for aqueous humour to be made
lots of blood vessels to allow aqeuous humour to be made
two layers of epithelium in ciliary body
pigmented
unpigmented
what is the main artery in the ciliary body
arterial - major arterial circle
what is the main vein in the ciliary body
vortex veins
what are the properties of the aqeuous humour
low viscosity
transparent
provides pressure
100 min to be produced and drain away
what is the ciliary process anatomical structure
zonular fibres
pigmented epithelium
unpigmented epithelium
stroma
blood vessels
what are the 3 secretion processes
secretion
ultrafiltration
dialysis
what is secretion
active pumps move Na+ ions out across the double epithelium layer to posterior chamber causing water to move via osmosis
ultrafiltration
salts are forced through by a pressure gradient
what is dialysis
small particles pass through the membrane but larger retained in ciliary processes
