The cell cycle as it occurs in somatic (body) cells has two major phases. One is Interphase, in which the cell prepares for division, and the other is mitosis in which the cell replicates itself. Interpha...

38 degrees Celsius is higher than the necessary core body temperature of 37 degrees. This is detected by the hypothalamus to reduce the temperature through a negative feedback system.The changes brought a...

A synapse is a chemical junction between a neurone and another cell. This next cell is often another neurone or a muscle cell. In this case we will describe a synapse between a two neurone cells. When an ...

Procaryotic cells lack organelles (e.g. nucleus) and other internal membrane-bound structures (e.g. endoplasmatic reticulum). Most of their genetic material (i.e. DNA) forms an irregularly shaped structur...

Mitosis is the way in which cells divide. Once one cell has undergone DNA replication, it contains 2 sets of chromosomes (diploid). Once mitosis has occurred, there will be two identical haploid...
