What is nasion and Inion? The nasion is the indentation between the forehead and the nose. •The inion is a ridge or knob that can be felt. as you run your finger up the back of the neck to the skull. You should first encounter a depression with the ridge of the protruding inion just above it.

The nasal “dorsum” is the bone-and-cartilage structure that connects your nose to your face. Most of us refer to it as the “bridge” of our nose. The dorsum can develop humps for several reasons.
What is the Sellion of the nose? The sellion is the deepest point of the nasofrontal angle at the intersection of forehead slope and the proximal nasal bridge. It is the soft tissue equivalent of the nasion. Centered at the nasion, the radix defines the nasal root and represents where the nose has its origin from the glabella.
How do I reduce the size of my nasal bone?
Your surgeon can reduce the width of the nose, to make it narrower, by breaking the bone and repositioning it. Surgeons can use bone or cartilage, or an implant, to change the contour of a ‘flat’ bridge or tip. This is called additional rhinoplasty or augmentation rhinoplasty.
What is Fp1 EEG? Fp1 and Fp2 are the left and right frontal pole EEG electrodes, respectively.
What is CZ in EEG?
Cz and Fz are ‘ground’ or ‘common’ reference points for all EEG and EOG electrodes, and A1-A2 are used for contralateral referencing of all EEG electrodes. This EEG montage may be extended to utilize T3-T4, P3-P4, as well as others, if an extended or “seizure montage” is called for.
What is the function of nasion? The nasion is the most anterior point of the frontonasal suture that joins the nasal part of the frontal bone and the nasal bones. It marks the midpoint at the intersection of the frontonasal suture with the internasal suture joining the nasal bones.
What is a Supratip?
Supratip deformity, previously defined as the polly beak or parrot beak deformity, is defined as a fullness or convexity located immediately cephalad to the nasal tip and may occur as both a primary and secondary deformity.
What ethnicity has dorsal humps? Hispanic and Mediterranean nose
The hallmark of Hispanic and Mediterranean noses is a dorsal hump over the nasal bridge. The tip of the nose is broad and drooping. Mediterranean descent includes people from southern Europe, northern Africa, and some parts of Asia, e.g. the Middle East.
What is nasal bridge?
Nasal bridge is the bony part of the nose, overlying the nasal bones, above the part in blue labeled “Cartilage of Septum”.
Is rhinoplasty a surgery? Rhinoplasty, commonly known as a nose job, is a plastic surgery procedure that can change the appearance of your nose. It is one of the most desired cosmetic procedures for both men and women alike.
What is an inverted V deformity?
An inverted V deformity refers to a narrowing of the middle third of the nose. This may occur following removal of a bump along the bridge of the nose and subsequent repositioning of the nasal bones.
What is a Supratip break? The supratip break is the step-off or the demarcation between the tip of the nose and the dorsum of the nose. It is essentially where the dorsum ends and the tip begins. This concept is often misunderstood by surgeons.
Why is my nose so big?
Large Nose: “Big” or wide noses can be hereditary, the result of aging, or caused by trauma. In addition to becoming crooked or developing bumps (as outlined in our guide to nose shape), broken noses often end up larger than before.

The structures and skin of the nose lose strength with time and, as a result, the nose stretches out and sags downward. The glands within the skin, especially in the area of the tip may enlarge, causing a wider appearing nose which is actually heavier.
What does electroencephalography measure? An EEG is a test that detects abnormalities in your brain waves, or in the electrical activity of your brain. During the procedure, electrodes consisting of small metal discs with thin wires are pasted onto your scalp. The electrodes detect tiny electrical charges that result from the activity of your brain cells.
What is bipolar montage in EEG?
Bipolar montages consist of chains of electrodes, each one connected to one or two neighboring electrodes. … It consists of a display in which each channel connects adjacent electrodes from anterior to posterior in two lines, essentially covering the parasagittal and temporal areas bilaterally.
What is 10/20 lead system in EEG? The 10-20 System of Electrode Placement is a method used to describe the location of scalp electrodes. These scalp electrodes are used to record the electroencephalogram (EEG) using a machine called an electroencephalograph. … Each point on this figure to the left indicates a possible electrode position.
What is Fpz in EEG?
The nomenclature for EEG electrodes follows the International 10-20 system. … Electrodes are named for the part of the brain they cover: F for frontal, C for central, and O for occipital (Figure F1-1). The central midline (vertex) electrodes (Cz) and the frontopolar midline electrode (Fpz) are also of interest.
What is Pterion of the skull? The pterion is a craniometric point near the sphenoid fontanelle of the skull. It is a point of convergence of the sutures between the frontal, sphenoid, parietal, and squamous temporal bones [1]. There are varied patterns of articulation of these bones and sometimes a small epipteric bone may be present.
What is the weakest part of the skull?
Clinical significance
The pterion is known as the weakest part of the skull. The anterior division of the middle meningeal artery runs underneath the pterion. Consequently, a traumatic blow to the pterion may rupture the middle meningeal artery causing an epidural haematoma.
What is frontal eminence? A frontal eminence (or tuber frontale) is either of two rounded elevations on the frontal bone of the skull. They lie about 3 cm above the supraorbital margin on each side of the frontal suture. They are the site of ossification of the frontal bone during embryological development, although may not be the first site.
