Biophysical LetterIncreased Tissue Stiffness in Tumors from Mice with Neurofibromatosis-1 Optic Glioma Although such relationships, i.e., between tumor development and stiffness, have been established for a variety of cancer types, the mechanical properties of optic nerve glioma, as well as their underlying acellular causes, are unknown. The normal optic nerve is a complex tissue composed of numerous distinct cellular and extracellular components. Similarly, optic nerve gliomas harbor a unique collection of neoplastic (astrocytes and stem cells) and non-neoplastic (endothelial cells and microglia) cell types embedded within a rich ECM.

Thin layer of tissue covering the front of the eye, except t The optic nerve head in a normal human eye carries about 1 million neurons from the eye towards the brain. The aqueous is the thin, watery fluid that fills the space between the cornea and the iris (anterior chamber). It is continually produced by the ciliary body, the part of the eye that lies just behind the iris.

Eye The fovea is an important region of the retina, as it contains the highest concentration of photoreceptors in the eye. Nervous tissue in the retina is connected to the brain through the optic nerve, which passes through a hole in the choroid and sclera in the posterior of the eye. Where the optic nerve forms there are no photoreceptors, resulting in a blind spot known as the optic disk.

Optic nerve Optic nerve. The optic nerve is located in the back of the eye. It is also called the second cranial nerve or cranial nerve II. It is the second of several pairs of cranial nerves. The job of the optic nerve is to transfer visual information from the retina to the vision centers of the brain via electrical impulses. The optic nerve is made of ganglionic cells or nerve cells. It consists of over one million nerve fibers.

Nervous tissue It is composed of neurons, or nerve cells, which receive and transmit impulses, and neuroglia, also known as glial cells or more commonly as just glia (from the Greek, meaning glue), which assist the propagation of the nerve impulse as well as providing nutrients to the neuron.ypically, nervous tissue is categorized into four types of tissue. In the central nervous system (CNS), the tissue types found are grey matter and white matter. In the peripheral nervous system (PNS), the tissue types are nerves and ganglia. The tissue is categorized by its neuronal and neuroglial components.

Scar tissue on optic nerveCailB Jun 02, 2013 Scar tissue on optic nerve. I have a friend who was severely abused as a child, and the result is scar tissue on the optic nerve. He is now in his early 40's and his eyes are preventing him from employment, as they are gradually getting worse and he can no longer pass the field vision test.

Nerve Tissue Nerve Tissue. Although the nervous system is very complex, there are only two main types of cells in nerve tissue. The actual nerve cell is the neuron. It is the conducting cell that transmits impulses and the structural unit of the nervous system. The other type of cell is neuroglia, or glial, cell.The word neuroglia means nerve glue.. These cells are nonconductive and provide a support system for the neurons. They are a special type of connective tissue for the nervous system.he other type of cell is neuroglia, or glial, cell.

Nerve Fiber Layer Along with the branches of the central retinal artery and vein, they make up the retinal nerve fiber layer (RNFL). Each axon proceeds in a more-or-less direct course toward the optic disc, located medially to the macula lutea. Axons which must pass near the macula lutea arch around it, keeping it free of obstruction. The optic disc (also called the optic nerve head) is the exit point for the ganglion cell axons. At the optic disc, these axons collect to form the optic nerve and as a group turn at right angles again, plunging through the retina, choroid, and sclera.

Optic Disc & Optic Nerve Optic Disc & Optic Nerve. The optic disc is a round area in the back of the eye where retinal nerve fibers collect to form the optic nerve. The optic disc is sometimes called the optic nerve head because it is the head of the optic nerve as it enters the eye from the brain. It is located slightly to the nasal side of the globe.

NERVOUS TISSUE Glial Cells. Regular connective tissue types surround the components of the central nervous system, but they are not found within the tissue. The glial cells, derived from neuroectoderm, serve roles of connective tissue within the CNS tissue.ERVOUS TISSUE. Nervous tissue is the fourth basic tissue type of the body and is organized into two basic systems: (1) the Central Nervous System (CNS) and (2) the Peripheral Nervous System (PNS).

The optic chiasm or optic chiasma is an X-shaped space just in front of the pituitary gland where optic nerve fibers pass through to the brain. The fibers from the nasal half of each retina cross over, but those from the temporal sides do not.

Is connective tissue avascular?   Avascular tissue is that which does not contain blood vessels or lymphatics. Examples include: The epithelial layer of the skin, cartilage, and the cornea and lens of … the eye. There are some types of connective tissue that are composed of elastic fibers that are avascular, too.

Connective tissue Dense regular connective tissue, which forms organized structures, is a major functional component of tendons, ligaments and aponeuroses, and is also found in highly specialized organs such as the cornea. Elastic fibers, made from elastin and fibrillin, also provide resistance to stretch forces.he other three types are epithelial, muscle, and nervous tissue. Connective tissue is found in between other tissues everywhere in the body, including the nervous system. In the central nervous system the outer membranes, the meninges, that cover the brain and spinal cord are composed of connective tissue.

The Optic Nerve The beginning of the optic nerve in the retina is called the optic nerve head or optic disc. Since there are no photoreceptors (cones and rods) in the optic nerve head, this area of the retina cannot respond to light stimulation. As a result, it is known as the blind spot, and everybody has one in each eye.

Optic nerve Anatomical terms of neuroanatomy. The optic nerve, also known as cranial nerve II, is a paired nerve that transmits visual information from the retina to the brain. The optic nerve is derived from optic stalks during the seventh week of development and is composed of retinal ganglion cell axons and glial cells.

optic-disc.org The optic nerve head, or disc, is defined as the distal portion of the optic nerve extending from the myelinated portion of nerve that begins just behind the sclera, to the retinal surface. Typically, it is slightly oval with the vertical diameter being about 9% greater than the horizontal.
