Question

Many subcortical structures, such as the hippocampus and amygdala, come in groups of two. why?
a.anatomy involves symmetry.
b.there is a hindbrain and midbrain.
c.it has to do with lateralization.
d.none of the above

Answer 1

The right answer is a.anatomy involves symmetry.

In the anatomy of multicellular animals with bilateral symmetry (which form the subregion of bilateria), there are many even organs, that is to say composed of two symmetrical halves, generally positioned on both sides of the median plane. This is the case, for example the human brain that includes two hemispheres, two amygdalas and two hyppocampus, a left and a right.

Answer 2

Many subcortical structures, such as the hippocampus and amygdala, come in groups of two because they have anatomy that involves symmetry.

The correct option is A.

What are the hippocampus and amygdala?

Hippocampus and amygdala are two lobes of brain. They are paired structures present in each hemisphere of the brain.

The amygdala is a structure in the medial temporal lobe that sits just ahead of the hippocampus.

The amygdala, like the hippocampus, is a paired structure, with one in each hemisphere of the brain.

Thus, the correct option is A, anatomy involves symmetry.
