Function of fibrous tunic?
The fibrous tunic of the eye provides structural support and protection, helping to maintain the shape of the eye and prevent damage from external forces. It consists of the sclera and cornea, which contribute to the eye's overall optical properties.
What is the name of the outermost white fibrous tunic of the eye?
The sclera also known as the white of the eye, maintain the shape of the eye and protects the delicate inner layers of tissue.This tough, fibrous tissue forms the outer layer of the eye, except for the part covered by the cornea. Scler/o means the white of the eye, and it also means hard.
What is the posterior portion of the vascular tunic?
The posterior portion of the vascular tunic is called the choroid. It is a layer of blood vessels that supply nutrients and oxygen to the retina. The choroid also helps to regulate the amount of light entering the eye by absorbing excess light.
What is the largest portion of the fibrous layer?
The meninges consist of three layers: dura mater, arachnoid mater, and pia mater. The dura mater is the thickest and toughest layer, making it the largest portion of the fibrous layer.
What is the fibrous membrane immediately surrounding the kindey?
The fibrous membrane immediately surrounding the kidney is called the renal capsule. It is a smooth, transparent sheath that helps to maintain the shape and protect the kidney.

How many layers do the eyes have?
The mammalian eye can be dividied into three main layers (tunics): fibrous tunic, vascular tunic, and the nervous tunic. The fibrous tunic consists of the cornea and the sclera. The vascular tunic includes the iris, ciliary body, and choroid. The nervous tunic includes the retina. rbb, MD

What are the three layers of the eye from the outer layer to the inner layer?
The eye contains three layers which are: the outer fibrous tunic, an intermediate vascular tunic, and an inner neural tunic (retina). The outer fibrous tunic function is to serve as the sclera and cornea. The cornea serves as a opening to the eye and helps with thefocus of light rays. The sclera protects from large and small particles and provides a connection for extrinsic muscles. The middle vascular tunic consists of three eye structures: choroid coat that helps to consumeexcess light, this is why the inside of the eye is dark and the ciliarry body which createsthe ciliary muscles and processes, and the iris which has smooth muscle controls the pupil size and also the colored part of the eye. The inner nervous tunic contains the retina andthe visual receptor cells. This portion of the eye is made of different cell types like the nerve cell.
What are the transparent fibrous membrane that forms a tube around the spinal cord?
Pia mater
What is the posterior portion of the vascular tunic?
The posterior portion of the vascular tunic is called the choroid. It is a layer of blood vessels that supply nutrients and oxygen to the retina. The choroid also helps to regulate the amount of light entering the eye by absorbing excess light.

What is the colorless structure of an eye?
The aqueous humor is the colorless transparent fluid portion of the eye.
What is the transparent central anterior portion of the eye through which light enters called?
the vitreous humor
Transparent anterior portion of the eye?
The transparent anterior portion of the eye is known as the cornea. It plays a crucial role in focusing light onto the retina at the back of the eye to create clear vision. The cornea has no blood supply and receives nutrients through the tear film and aqueous humor.
