Central giant-cell granuloma (CGCG) is a localised benign condition of the jaws.It is twice as common in females and is more likely to occur before age 30. Central giant-cell granulomas are more common in the anterior mandible, often crossing the midline and causing painless swellings.
The Robo proteins are critical regulators of midline crossing across species. In Drosophila embryos, Robo1 and Robo2 are required to keep ipsilaterally projecting axons from inappropriately crossing the midline, and to prevent contralateral axons from remaining stuck at the midline. Robo3, while it also binds Slit, does not appear to play a ...
This article is about the optic chiasm of vertebrates, which is the best known nerve chiasm, but not every chiasm denotes a crossing of the body midline (e.g., in some invertebrates, see Chiasm (anatomy)). A midline crossing of nerves inside the brain is called a decussation (see Definition of types of crossings).
The posterior commissure (also known as the epithalamic commissure) is a rounded nerve tract crossing the middle line on the dorsal aspect of the upper end of the cerebral aqueduct. It is important in the bilateral pupillary light reflex.

If a mass in the abdominal wall does not cross midline and does not change with flexion of the rectus muscles, this is a positive sign for a rectus sheath hematoma. It is named for English obstetrician William Edward Fothergill , who described features of rectus sheath hematomas in a 1926 article in the British Medical Journal entitled ...
The midline nuclear group (or midline thalamic nuclei) is a region of the thalamus consisting of the following nuclei: paraventricular nucleus of thalamus (nucleus paraventricularis thalami) - not to be confused with paraventricular nucleus of hypothalamus; paratenial nucleus (nucleus parataenialis) nucleus reuniens (also known as the ...
The presence of the ATNR, as well as other primitive reflexes, such as the tonic labyrinthine reflex (TLR), beyond the first six months of life may indicate that the child has developmental delays, at which point the reflex is atypical or abnormal. For example, in children with cerebral palsy, the reflexes may persist and even be more ...
