On the nasal surface of the body of the maxilla, in front of the opening of the sinus is a deep groove, the lacrimal groove (or lacrimal sulcus), which is converted into the nasolacrimal canal, by the lacrimal bone and inferior nasal concha; this canal opens into the inferior meatus of the nose and transmits the nasolacrimal duct.
One root cause of brain fog could be inflammation, says Von Ah. Certain conditions can cause lots of inflammation, resulting in damage throughout the body, including the brain. Inflammatory ...
This underlying cause is reversible if you quit the meds, but other reversible causes might not be so obvious. Depression or major stress could cause impairment to show up in testing, too, Boyle says.
Brain fog is a common symptom in many illnesses where chronic pain is a major component. [26] Brain fog affects 15% to 40% of those with chronic pain as their major illness. [27] In such illnesses, pain processing may use up resources, decreasing the brain's ability to think effectively. [26]
In neuroanatomy, a sulcus (Latin: "furrow"; pl.: sulci) is a shallow depression or groove in the cerebral cortex.One or more sulci surround a gyrus (pl. gyri), a ridge on the surface of the cortex, creating the characteristic folded appearance of the brain in humans and most other mammals.
The lateral or orbital surface is divided by a vertical ridge, the posterior lacrimal crest, into two parts.. In front of this crest is a longitudinal groove, the lacrimal sulcus (sulcus lacrimalis), the inner margin of which unites with the frontal process of the maxilla, and the lacrimal fossa is thus completed.
The lacrimal sac or lachrymal sac [1] is the upper dilated end of the nasolacrimal duct, [2] and is lodged in a deep groove formed by the lacrimal bone and frontal process of the maxilla. It connects the lacrimal canaliculi , which drain tears from the eye's surface, and the nasolacrimal duct , which conveys this fluid into the nasal cavity. [ 3 ]
There is a region of the central sulcus, called the “hand knob”, which is a notch in the area of the hand motor region. The position of this “knob” can be indicative as well of someone's handedness. [11] As motor functions develop, it is expected that the shape of the central sulcus will change.
