Sphenoid bone of the skull. It is the most interesting bone in the skull.
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.
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).
Foramen ovale ...i take a medical assistant course
Some times the foramen ovale does not get closed soon after the birth. This condition is called as patent foramen ovale.
The mandibular nerve passes through foaramen ovale of the spenoid bone. Blood passes through the foamen ovale of the heart of the fetus.
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.
I think its the 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.
The natural way to promote closure of the foramen ovale is to breathe.
Foramen ovale is a window between the 2 auricle before birth
That is a very good question! In case of the fetus, the blood flow through the lungs is closed. So most of the blood passes through the foramen ovale to left atrium. Some blood goes to right ventricle. it is pumped by the right ventricle into pulmonary aorta. This blood passes to systemic aorta via ductus arteriosus. Both the blood flows stops after the birth of the baby. Baby takes a first breath. Blood starts to flow through the lungs. Due to pressure changes the foramen ovale get closed. By the same reason the ductus arteriosus get closed, as the circular muscles of the artery can contract.
Patent foramen ovale is a common heart condition where a small hole in the heart that typically closes after birth remains open. This opening can allow blood to bypass the lungs and mix oxygenated and deoxygenated blood, which may lead to potential health issues like a higher risk for stroke.
