Question

Rostral to caudal patterning in the neural tube uses-

a) Shh gradient
b) BMP signaling
c) Wnt activation
d) FGF induction

Answer 1

Rostral to caudal patterning in the neural tube is achieved through the use of growth factors signaling some ectodermal cells to form epidermal cells, while the remaining cells become the neural plate.

Step-by-step explanation:

In vertebrates, the rostral to caudal patterning in the neural tube is achieved through the use of growth factors. These growth factors signal some of the ectodermal cells to form epidermal cells, while the remaining cells form the neural plate. The neural plate eventually develops into the entire neural tube.
