What is external limiting membrane?
The external limiting membrane (or outer limiting membrane) is one of the ten distinct layers of the retina of the eye. It has a network-like structure and is situated at the bases of the rods and cones.
What forms the external limiting membrane?
The external limiting membrane (or outer limiting membrane) is situated at the bases of the rods and cones with a network-like structure. This is the line formed by junctional complexes between photoreceptor and Müller cells (supportive cells).
What is the limiting membrane of the cell?
FMA. 58689. Anatomical terminology. The internal limiting membrane, or inner limiting membrane, is the boundary between the retina and the vitreous body, formed by astrocytes and the end feet of Müller cells. It is separated from the vitreous body by a basal lamina.
What does membrane limited mean?
limiting membrane one that constitutes the border of some tissue or structure.
What are Müller cells?
Müller cells, the major type of glial cells in the retina, are responsible for the homeostatic and metabolic support of retinal neurons. By mediating transcellular ion, water, and bicarbonate transport, Müller cells control the composition of the extracellular space fluid.
What is outer nuclear layer?
The outer nuclear layer (or layer of outer granules or external nuclear layer), is one of the layers of the vertebrate retina, the light-detecting portion of the eye.
Why is plasma membrane called a limiting membrane?
A membrane which allows certain substances to pass, but does not allow others to pass through it is called a selectively permeable membrane.
What are the organelles with limiting membrane?
These are the so-called membrane bound organelles, such as the lysosomes, Golgi complex, and mitochondria.
What organelle has no limiting membrane?
Answer: Ribosomes are the cell organelle which is devoid of cell membrane. Explanation: It is the site of protein production in the cells of plant and animal.
