Fоr eаch stаtement аbоut sоmite formation, indicate whether it is true (T) or false (F) [answer1] Somites form from the lateral plate mesoderm. [answer2] All vertebrate species form the same number of somites. [answer3] Somites form on both sides of the neural tube, from the forebrain through the tail of the organism. [answer4] Two somites form simultaneously, one on each side of the neural tube. [answer5] The time between the formation of somites (the periodicity) is unique for a particular species, and is stays roughly constant throughout somite formation. [answer6] The somites form in response to signaling oscillations from the adjacent neural tube. [answer7] The somites go on form the kidney and somatic portion of the gonad. [answer8] The mesoderm location where a new somite will form can be predicted by the expression domain of the mesp2 [answer9] Ephrin repulsion is important in creating separation between somites as they epithelialize. [answer10] Changes in Notch signaling in humans during somite formation can lead to neural tube closure defects.
