Explanation:
Answer:
The neurulation process involves two steps: Primary neural induction and Secondary neural induction.
Explanation:
Neurulation may be defined as the process of formation of neural tube from the neural plate. Neurulation starts when the notochord induces the formation of central nervous system.
Two main stages of neurulation are:
Primary neural induction: Primary neurulation is the process of transformation of flat neural plate into circular neural plate. Gene products gradient determines the induction of neural plate.
Secondary neurulation: The medullary cord is formed by the neural ectoderm and endoderm. Cavites formed from the medullary cord changes into the single neural tube.
Answer:
Connective Tissue.
Explanation:
In the absence of lumen, without much arguments, it looks like a densely packed <em>connective tissue. I</em>i<em>i</em>i<em>I</em>t possesses a low cell count when it is been compared to the extracellular matrix.
