Eyelash length is closely linked to the width of the eye, with the lashes typically growing to one-third the width of the eye as an evolutionary adaptation to reduce tear film evaporation and dust deposition. Lashes longer or shorter than one-third the width of the eye have been shown to have reduced efficacy in serving their function. [5]
Some motile cilia lack the central pair, and some non-motile cilia have the central pair, hence the four types. [5] [7] Most non-motile cilia, termed primary cilia or sensory cilia, serve solely as sensory organelles. [8] [9] Most vertebrate cell types possess a single non-motile primary cilium, which functions as a cellular antenna.
A. ciliaris can be identified by the tiny white "eyelashes", or "cilia" (=ciliaris), that line the leaves, fully encircling the stem at their bases.. The common climbing-aloe can be differentiated from other Aloiampelos species by the way that the soft, white, hair-like teeth ("cilia"=ciliaris) that appear along the leaf margins, extending fully around the stem at the base of the leaf.
The eyebrows, eyelids, eyelashes, lacrimal gland and drainage apparatus all play a crucial role with regards to globe protection, lubrication, and minimizing the risk of ocular infection. [1] The adnexal structures also help to keep the cornea moist and clean. One source defines "ocular adnexa" as the orbit, conjunctiva, and eyelids. [2]
Moll's gland, also known as the gland of Moll or ciliary gland, is a modified apocrine sweat gland that is found on the margin of the eyelid.They are next to the base of the eyelashes, and anterior to the meibomian glands within the distal eyelid margin.
The whisker-like hairs are so long that she can hold them together.
Demodex / ˈ d ɛ m ə d ɛ k s / is a genus of tiny mites that live in or near hair follicles of mammals.Around 65 species of Demodex are known. [2] Two species live on humans: Demodex folliculorum and Demodex brevis, both frequently referred to as eyelash mites, alternatively face mites or skin mites.
They work by placing the magnetic false lash between one's eyelashes, thereby sandwiching the natural eyelashes with magnetic eyelashes. [19] These lashes are affordable and reusable but there is a potential risk — due to the magnets that are attached to the lashes it is possible that they may be a hazard to a patient if being used in an ...
