To answer whether eyes have cilia requires understanding what cilia are and where they might be found in relation to the eye and its surrounding structures. The provided reference mentions the ciliary body, which is a part of the eye, but that is not the same as cilia. The ciliary body is a circular structure that is an extension of the iris.
What are Cilia?
Cilia are small, hair-like structures found on the surface of certain cells. They can be motile (moving) or non-motile (stationary). Motile cilia beat in a coordinated manner to move fluids or particles across a cell's surface. Non-motile cilia often act as sensory antennae, receiving signals from the environment.
Cilia in the Eye and Surrounding Structures
While the ciliary body is a component of the eye responsible for producing aqueous humor and controlling the lens shape, the reference doesn't directly address if other parts of the eye or its immediate structures possess true cilia. However, cilia are present in the respiratory tract, where they help to move mucus and debris away from the lungs. The lacrimal system, which includes the tear ducts responsible for draining tears from the eye, is lined with epithelium, and it's possible that ciliated cells are present to aid in fluid drainage. However, further research would be necessary to confirm this.
Summary
The term "ciliary body" might be confused with the presence of "cilia," but they are distinct. The ciliary body is a structural component of the eye. The provided reference doesn't explicitly mention cilia being present on the surface of the eye itself. Further, the question is ambiguous. It is not clear if it is asking if the eye ball has cilia, or if the ciliary body has cilia.
