The axons of the retina culminate in what nerve?
the axons of the retina culminate in the optic nerve which forms a blind spot on the retina
Why is there no sensation of light at the optic disk?
Because there are no rods or cones there, since the optic disk is where axons exit the eye to form the optic nerve.
Difference between optic tract and optic nerve?
Bundles of neuron processes are called tracts in the cns and nerves in the pns
What is the junction of the retina and optic nerve?
The junction between the retina and the optic nerve is the optic disc.
Does the optic nerve pass through the foramen ovale?
The natural blind spot (scotoma) is due to lack of receptors (rods or cones) where the optic nerve and blood vessels leave the eye. It is where the optic nerve leaves the retina not enter it. The optic disk or blind spot is where the optic nerve leaves the eye; you cannot use that field of vision because the optic nerve is there.
What nerve is composed of axons of the ganglion cells and transmits action potentials the thalamus of the brain?
Optic nerve
Do the axons of retinal ganglion cells form the optic nerve?
Yes. The Retinal Ganglion Cell axons form the optic nerve.
The axons of the retina culminate in what nerve?
the axons of the retina culminate in the optic nerve which forms a blind spot on the retina
Why is there no sensation of light at the optic disk?
Because there are no rods or cones there, since the optic disk is where axons exit the eye to form the optic nerve.
Which neuron layers of an axon form the optic nerve?
There are three layers of neurons in the retina. The axons of GANGLION CELLS form the optic nerves.
What is the function of optic disk?
It's the place in the eye where axons exit the eye to form the optic nerve, and where blood vessels enter to nourish the retina.
Difference between a neuron and a nerve?
A bundle of axons is a nerve. A neuron is the cell of the nervous system and is composed of dendrites, axon, and the cell body.
What is the function of the optic disk in the eye?
Optic disc:The optic disc is also called the blind spot. There are no receptors in this part of the retina. This is where all of the axons of the ganglion cells(last neurons before optic nerve) exit the retina to form the optic nerve.
What are Bundles of axons are called?
NERVES
Difference between optic tract and optic nerve?
Bundles of neuron processes are called tracts in the cns and nerves in the pns
What are nerves composed of?
Nerves are composed of nerve cells; the long connecting parts of the nerve cells are called axons. The biochemistry of nerve cells is similar to that of other cells, but they do have an insulating layer, the myelin sheath, which gives them a relatively high concentration of fat.
Where do axons from the olfactory nerve project to?
Axons from the olfactory nerve project directly to the
