neural fold การใช้

• One of the fragments clearly showed the neural folds of a cerebral lobe.
• The formation of the neural fold is initiated by the release of calcium from within the cells.
• These two grooves in the neural folds transform into optic vesicles with the closure of the neural tube.
• Beginning in the future neck region, the neural folds of this groove close to create the neural tube.
• Closure of the neural tube is completed when the neural folds are brought together, adhering to each other.
• Areas caudal to neural tube closure have PAX3 and MSX expression restricted to lateral regions of the neural folds.
• Between these neural folds, a groove forms and deepens as the folds roll over it to converge on the midline.
• As the primitive streak regresses and neural folds gather ( to eventually become the neural tube ), the paraxial mesoderm separates into blocks called somites.
• He first named it Zwischenstrang, which literally translated to mean  intermediate cord .  The name neural crest develops from the neural folds during embryonic development.
• Beginning in the future neck region, the neural folds of this groove close to create the neural tube ( this form of neurulation is called primary neurulation ).
• As a result, these cells dissociate from neural folds, gain motility, and disseminate to various parts of the embryo, where they differentiate to many other cell types.
• The neural groove gradually deepens as the neural folds become elevated, and ultimately the folds meet and coalesce in the middle line and convert the groove into the closed neural tube.
• At the same time during embryonic development, the ectoderm begins to thicken and fold upward, forming the neural folds, which eventually meet to form the neural tube and neural crest.

• After recruitment from the ectoderm, the neuroectoderm undergoes three stages of development : transformation into the neural plate, transformation into the neural groove ( with associated neural folds ), and transformation into the neural tube.
• When the cells at the peaks of the neural folds come in proximity with each other, it is the affinity for similar cadherin molecules ( N-cadherins ) that allows these cells to bind to each other.
• This organizer prevents BMP-4 from inducing the ectoderm in the future head region of the embryo to become epidermis; it instead allows the future head region to form neural folds, which will eventually turn into the brain and spinal cord.
• Three main ventral cell types are established during early neural tube development : the " floor plate cells ", which form at the ventral midline during the neural fold stage; as well as the more dorsally located motor neurons and interneurons.
• The groove gradually deepens as the neural folds become elevated, and ultimately the folds meet and coalesce in the middle line and convert the groove into a closed tube, the neural tube or canal, the ectodermal wall of which forms the rudiment of the nervous system.
• Before the neural groove is closed a ridge of ectodermal cells appears along the prominent margin of each neural fold; this is termed the neural crest or ganglion ridge, and from it the spinal and cranial nerve ganglia and the ganglia of the sympathetic nervous system are developed.
