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 is the mandibular division of trigeminal nerve?
The mandibular division of the trigeminal nerve (V3) is responsible for providing sensation to the lower jaw, teeth, gums, and part of the tongue. It also controls the muscles involved in chewing. It is the largest branch of the trigeminal nerve and exits the skull through the foramen ovale.
What is the Small hole that allows for blood to flow from the right atrium to the left atrium during embryonic development?
The small hole that allows for blood to flow from the right atrium to the left atrium during embryonic development is called the foramen ovale. It is a temporary opening in the septum between the two atria. After birth, when the lungs begin functioning, the foramen ovale typically closes, allowing blood to flow in the correct direction through the heart.
What is the function of the foramen ovale after birth?
There is more than one structure called the foramen ovale. In the skull the foramen ovale is one of the many foramina through the base of the cranium. It is through this foramen that the mandibular nervre (CN V3) and the accessory meningeal artery pass. There is another structure in the fetal heart called the foramen ovale. This structure is effectively a hole in the atrial septum that allows blood flow directly from the right to the left atrium, bypassing the right ventricle and the lungs. This is possible because the lungs are not in use in the fetal stage (as the fetus is in a liquid environment) and all the oxygen is coming from the placenta. The foramen ovale allows blood to bypass the lungs before birth.
What is the foramen ovale and what is its fate after birth?
That is very good question! You get the oxygenated blood from the placenta via umbilical vein in case of the fetus. This vein enters the liver of the fetus. The blood then goes to right atrium of the fetus. The lungs are closed in the fetus. So the blood goes to left atrium through foramen ovale to bypass the pulmonary circulation of the fetus. After the birth of the baby, baby takes the first breath. The lungs get inflated. Blood starts to flow via lungs. This closes the foramen ovale. The marking remains there on the wall between both the atria.
What is the foraman ovule opening?
The foramen ovale is a small hole in the heart that allows blood to bypass the lungs before birth. It typically closes shortly after birth in a healthy individual but may remain open in some cases, leading to a condition known as a patent foramen ovale.
What passes through the foramen rotundum?
The maxillary nerve (V2) passes through the foramen rotundum, which is a circular opening in the sphenoid bone located in the middle cranial fossa. The maxillary nerve is a branch of the trigeminal nerve (V).
What passes through the foramen ovale?
Sphenoid bone of the skull. It is the most interesting bone in the skull.
Where mental foramen belong to?
Foramen ovale is a window between the 2 auricle before birth
What are the openings in the fetal heart?
Foramen ovale ...i take a medical assistant course
What is foramen ovale?
Some times the foramen ovale does not get closed soon after the birth. This condition is called as patent foramen ovale.
What is foreman ovale?
Foreman ovale, or "oval window," is a term used to describe a small, oval-shaped opening that separates the middle ear from the inner ear in the human skull. It is covered by a membrane and plays a crucial role in transmitting sound vibrations from the middle ear to the fluid-filled inner ear.
What is connects the two atria in the fetal heart?
I think its the foramen ovale.
Where can one find more information about Foramen Ovale?
One can find more information about Foramen Ovale from the Mayo Clinic website. The Foramen Ovale is located within the fetal heart and it allows blood to enter and move through the left atrium after the right.
What is the natural way of promoting closure of the foramen ovale?
The natural way to promote closure of the foramen ovale is to breathe.
What passes through the foramen magnum?
The mandibular nerve passes through foaramen ovale of the spenoid bone. Blood passes through the foamen ovale of the heart of the fetus.
The embryonic remnant of the Foramen Ovale is called what?
The embryonic remnant of the foramen ovale is called the fossa ovalis. During fetal development, the foramen ovale allows blood to bypass the non-functioning lungs by flowing directly from the right atrium to the left atrium. After birth, the foramen ovale typically closes and becomes the fossa ovalis, a thin, oval-shaped depression in the interatrial septum of the heart.
What is the mandibular division of trigeminal nerve?
The mandibular division of the trigeminal nerve (V3) is responsible for providing sensation to the lower jaw, teeth, gums, and part of the tongue. It also controls the muscles involved in chewing. It is the largest branch of the trigeminal nerve and exits the skull through the foramen ovale.
