They also learn to compensate for refraction. When they plunge into the water, the eyes are protected by a membrane. So they actually catch their prey blind, relying on touch to decide when to snap their bills shut. They then fly straight out of the water with their prey in their bills.

What else can I help you with?
Do fibers of the optic nerve synapse at lateral genticulates of the thalamus?
It is a true statement that fibers of the optic nerve synapse at lateral genticulates of the thalamus.
Can a pale optic disc get better?
No, once a pale optic disc develops, it typically does not improve. A pale optic disc is often a sign of damage to the optic nerve or loss of nerve fibers, which are irreversible. It is important to identify the underlying cause and manage any associated conditions to prevent further damage.
How many percent of the optic nerve fibers are responsible for light reflex?
Approximately 20% of the optic nerve fibers are responsible for the light reflex. These fibers are involved in transmitting the signal from the retina to the brain to regulate the constriction of the pupil in response to changes in light intensity.
Where do half of the fibers of each optic nerve decussate at?
Half of the fibers of each optic nerve decussate at the optic chiasm, which is located at the base of the brain just in front of the pituitary gland. This crossing allows visual information from the right visual field to be processed by the left hemisphere and vice versa. The decussation is crucial for binocular vision and depth perception. After crossing, the fibers continue as the optic tracts to the lateral geniculate nucleus of the thalamus.
Is the optic nerve a single nerve or a bunch of nerves connected?
It is a bundle of neurons, all flowing from the same general source (the eye) to the optic chiasm.
Place where optic nerve fibers cross in the brain?
the optic disk
Do fibers of the optic nerve synapse at lateral genticulates of the thalamus?
It is a true statement that fibers of the optic nerve synapse at lateral genticulates of the thalamus.
Are optic fibers easy to brake?
Yes
What is dark fibers?
In fiber optic communcations Dark Fiber or Unlit Fibers refers Unused fibers, available for use
What is the function of the optic chiasm?
The optic chiasma is in front of the pituitary gland where optic nerve fibers pass to the brain. The function of the optic chiasma is to relay electric signals as they pass from the optic nerve to the brain.
Why the white dot became a black dot in the optic nerve?
The white dot in the optic nerve likely represents an area of demyelination, where the protective myelin sheath around nerve fibers has been damaged or lost. This can occur due to various conditions, such as multiple sclerosis or optic neuritis, leading to a change in the appearance of the optic nerve. As the nerve fibers become more exposed, they may appear darker in color on imaging studies. This change signifies underlying pathology affecting optic nerve function.
Can a pale optic disc get better?
No, once a pale optic disc develops, it typically does not improve. A pale optic disc is often a sign of damage to the optic nerve or loss of nerve fibers, which are irreversible. It is important to identify the underlying cause and manage any associated conditions to prevent further damage.
The area where some fibers from the eye cross over to the opposite side is called the?
Each eye contains an optic nerve, as the meet at the optic chiasm, some of the nerve fibers cross over. This sensitive area is referred to as the optic nerve pathway crossover.
Optic fibers are that arer able to transmit light waves from one place to another?
transparent glass fibers
What cranial nerves does not contain preganglionic parasympathetic fibers?
optic (II)
How many percent of the optic nerve fibers are responsible for light reflex?
Approximately 20% of the optic nerve fibers are responsible for the light reflex. These fibers are involved in transmitting the signal from the retina to the brain to regulate the constriction of the pupil in response to changes in light intensity.
Branches of the optic nerve go directly to what areas of the brain?
Optic nerve have no branches.Any way fibers from optic nerve ultimately reaches visual cortex(occipital lobe).
