How is cerebral-spinal fluid formed?
It is formed by filtration of blood through the fenestrations of the choroidal capillaries in the choroid plexus. It is flows by the active transport of substances (Particularly sodium ions) across the choroid epithelium into the ventricle, water then flows passively across to maintain osmotic balance. It has also been shown that if the choroid plexus was removed the ventricles still produced substantial quantities of CSF, though less than normal. And is generally considered to be fluid movement from CNS capillaries into the parenchyma of the brain, and from there across the ependymal lining into the ventricle.
Do choroid cysts only appear in the eye?
Choroid cysts primarily occur in the eye, specifically in the choroid layer of the eye, which is located between the retina and the sclera. However, similar cystic structures can also appear in other parts of the body, such as the brain (e.g., choroid plexus cysts). While the term "choroid cyst" is most commonly associated with the eye, it's important to recognize that cysts can form in various tissues and organs.
Is choroid the pigmented layer of the eye?
No, the choroid is not the pigmented layer of the eye. The pigmented layer is called the retina, specifically the pigmented epithelium layer of the retina. The choroid is a vascular layer located behind the retina that provides oxygen and nutrients to the retina.
What is xanthogranuloma of the choroid plexus?
Xanthogranuloma of the choroid plexus is a rare benign lesion characterized by a collection of lipid-laden macrophages within the choroid plexus of the brain. It is typically an incidental finding on imaging studies and usually does not require treatment unless it is causing symptoms.
What is a choroid and what is its function?
Absorbs light, and protects your eye.
Cerebrospinal fluid is formed by capillary knots?
Cerebrospinal fluid is primarily produced by specialized structures in the brain called choroid plexus, rather than capillary knots. These choroid plexus structures filter blood plasma to create cerebrospinal fluid, which serves to protect the brain and spinal cord.

What color is the choroid?
choroid is black in colour with a lot many nerve fibres to nourish the organ that is eye.
Which two involuntary muscles are located in the front part of the choroid?
One of the two muscles that make up the front part of the choroid is the ciliary muscles. Another one that makes up the choroid is the iris.

Where is CSF made?
choroid plexuses
What is the function of choroidea?
The choroid, also known as the choroidea or choroid coat, is the vascular layer of the eye, containing connective tissue, and lying between the retina and the sclera. The human choroid is thickest at the far extreme rear of the eye (at 0.2 mm), while in the outlying areas it narrows to 0.1 mm.[1] The choroid provides oxygen and nourishment to the outer layers of the retina. Along with the ciliary body and iris, the choroid forms theuveal tract.

Is the choroid is also known as the white of the eye?
No. The outer layer of the eyem the white part, is the sclera. The choroid is the next layer and the retinal is next.

No, the choroid is not the pigmented layer of the eye. The pigmented layer is called the retina, specifically the pigmented epithelium layer of the retina. The choroid is a vascular layer located behind the retina that provides oxygen and nutrients to the retina.
What is the vascular middle layer of the eye that provides the eye with blood called?
This is the middle layer of the eyeball and it is composed of the choroid, ciliary body and iris.
