I believe those are called centrioles. The structure is a centromere.
The nuclear membrane around the chromosomes.

In the brain, they are called glial cells.
chromosomes
Homologous chromosomes are held together by a protein structure called the synaptonemal complex during meiosis. This complex helps align the chromosomes and facilitate genetic recombination between homologous chromosomes.

Chromosomes are held together by protein structures called histones, which help package and organize the genetic material within the nucleus of a cell. The histones form complexes around which the DNA wraps, forming a structure known as chromatin. This allows the genetic material to be tightly packed and efficiently stored within the cell.
In biology, chiasma refers to the site where genetic material is exchanged between homologous chromosomes during meiosis. This process, known as crossing over, increases genetic diversity by shuffling genetic information between chromosomes.
