The episclera is the outermost layer of the sclera (the white of the eye). [1] It is composed of loose, fibrous, elastic tissue and attaches to Tenon's capsule. [1]A vascular plexus is found between the bulbar conjunctiva and the sclera consisting of two layers of vessels, the superficial episcleral vessels and the deep episcleral vessels.
In the anatomy of the eye, the conjunctiva (pl.: conjunctivae) is a thin mucous membrane that lines the inside of the eyelids and covers the sclera (the white of the eye). [1] It is composed of non-keratinized, stratified squamous epithelium with goblet cells , stratified columnar epithelium and stratified cuboidal epithelium (depending on the ...
The conjunctiva is a tissue that lines the inside of the eyelids and covers the sclera. It is composed of unkeratinized, stratified squamous epithelium with goblet cells, and stratified columnar epithelium. The conjunctiva is basically transparent, and the white colour we see is actually sclera.
The sclera's blood vessels are mainly on the surface. Along with the vessels of the conjunctiva (which is a thin layer covering the sclera), those in the episclera render the inflamed eye bright red. [6] In many vertebrates, the sclera is reinforced with plates of cartilage or bone, together forming a circular structure called the sclerotic ring.
The anterior ciliary arteries contribute arterial blood supply to the rectus muscles, conjunctiva, sclera, [2] [1] and the ciliary body. [citation needed] The anterior ciliary arteries issue branches to the conjunctiva before piercing the sclera, forming an artieral network in the limbal conjunctiva. They also issue branches to the episclera. [2]
A thin layer called the conjunctiva sits on top of this. The front part is also called the anterior segment of the eye. The eye is not shaped like a perfect sphere; rather it is a fused two-piece unit, composed of an anterior (front) segment and the posterior (back) segment. The anterior segment is made up of the cornea, iris and lens.
From ancient history to the modern day, the clitoris has been discredited, dismissed and deleted -- and women's pleasure has often been left out of the conversation entirely. Now, an underground art movement led by artist Sophia Wallace is emerging across the globe to challenge the lies, question the myths and rewrite the rules around sex and the female body.
This is a rather small section of the electromagnetic spectrum, probably reflecting the submarine evolution of the organ: water blocks out all but two small windows of the EM spectrum, and there has been no evolutionary pressure among land animals to broaden this range. [50] The most sensitive pigment, rhodopsin, has a peak response at 500 nm. [51]
