ciliary

Which four-letter word, beginning with "U", is the pigmented layer of the eye, lying beneath the sclera and cornea, and comprising the iris, choroid and ciliary body?

(11) for the HE staining evaluation of inflammatory cell count, ciliary cell count, epithelial thickness, and subepithelial thickness.

Evolutionarily convergent features in the development of these abbreviated forms include large eggs, bullet-shaped larval bodies, loss of feeding structures and a larval skeleton, the presence of uniform ciliation or transverse ciliary bands used for swimming, and decreased time to the juvenile stage (Emlet et al., 1987; Hendler, 1991; Emlet, 1994; Wray, 1996).

Across the Tree of Life, such large ciliary structures are only found in comb jellies."

Aqueous humor is produced in the ciliary processes of the ciliary bodies by two mechanisms - by active secretion (80%) and through ultrafiltration of plasma (20%).

The proposed pathophysiological mechanism involves anticholinergic effects and a possible serotonergic mechanism due to the presence of 5-HT receptors in human eyes and their concentration in the mammalian ciliary body and cornea.[1] The strong stimulation of serotonergic transmission could also account for the increase in IOP, as has been reported with other SSRIs.[1],[5] When stimulated by agonists, 5-HT receptors are responsible for relaxation of the sphincter muscle of the pupil and subsequent mydriasis.

Destruction of the ciliary body using various methods is an option for the management of refractory glaucoma when conventional medical and or surgical modalities fail to adequately control intraocular pressure (IOP).

There are blood test, ciliary function test, CT scan of the sinuses, nasal cytology and allergy testing and MRI of the sinuses.

Kartagener's syndrome is a type of ciliary motility disorder called primary ciliary dyskinesia.

The non-pigmented ciliary epithelial cells of the ciliary body pars plicata produce aqueous humour.

Microscopic analysis revealed an absence of one of the microtubule doublets in three of the outer doublets of the axoneme, thereby establishing a diagnosis of isolated ciliary dysfunction.
