These are the brain, heart, kidneys, liver, and lungs. The human brain is the body's control center, receiving and sending signals to other organs through the nervous system and through secreted hormones.
For the beetle genus, see Coprini. Synapsis (also called syndesis) is the pairing of two homologous chromosomes that occurs during meiosis. It allows matching-up of homologous pairs prior to their segregation, and possible chromosomal crossover between them. Synapsis takes place during prophase I of meiosis.
In what sense may prophase and telophase in mitosis be characterized as opposites. In telophase, the spindle formed in prophase comes undone. The nuclear envelope that broke down in prophase has reformed and multiplied into two. Whatever occurs in prophase is opposite in telophase.
