Vedmedyk [2.9K]

Answer:

C - Contains the embryonic disk

Explanation:

After an egg is fertilized, it begins to divide into smaller cells, from the 1 cell stage, to 2, to 4 and so on. Then, on the third day, the cells fall within 16-200 cells and it is then called a <em>morula</em>.

On the fifth day, the morula becomes a ball of calls which is now differentiated into an <em>inner cell mass and a trophectoderm</em>. The inner cell mass becomes the <em>embryo</em> as development goes on and the trophectoderm, becomes the <em>placenta</em>.

As development goes on further, the floor of the amniotic cavity is formed by the embryonic disk, a layer of prismatic cells derived from the inner cell mass.

The embryonic disc develops into 3 layers:

  • Endoderm
  • Mesoderm
  • Ectoderm

There is a major differentiation of cells which gives a template  for the origin of development of specific organs of the embryo.

polet [3.4K]

Both nervous and endocrine system are similar in a way that they perform the regulatory function in the body and act as regulator in various body functions.

Difference

1. nervous  system uses  electrical impulses (neural)for signaling while endocrine system  uses chemical signals called hormones, which travel through the bloodstream and control the actions of cells and organs.

2. The nervous system can respond quickly to stimuli, through the use of action potentials and neurotransmitters. Responses to nervous system stimulation are typically quick but short lived. The endocrine system responds to stimulation by secreting hormones into the circulatory system that travel to the target tissue.
