Transcript of Copy of Copy of specialized cells

specialized cells
Cells may be specialized for a particular function. Their structure will allow them to carry this function out.
Cells become specialized because the genes that are not required are switched off. Only the genes needed to make a particular type of cell work are switched on. So muscle cells only have the genes needed to make muscle cell proteins switched on. All the other genes, such as those needed to make blood cell proteins and nerve cell proteins, are switched off.
there are millions of cells in our bodies but we can't see them because there so small and we would need a microscope to see what they look like
nerve cells!
The human body is made up of trillions of cells. Cells of the nervous system, called nerve cells or neurons, are specialized to carry "messages" through an electrochemical process. The human brain has approximately 100 billion neurons.
Neurons have specialized extensions called dendrites and axons. Dendrites bring information to the cell body and axons take information away from the cell body.
Neurons communicate with each other through an electrochemical process.
Neurons contain some specialized structures (for example, synapses) and chemicals (for example, neurotransmitters)
Neurons are surrounded by a cell membrane.
Neurons have a nucleus that contains genes.
Neurons contain cytoplasm, mitochondria and other organelles.
Neurons carry out basic cellular processes such as protein synthesis and energy

nerve cells be in your nervous system
Neurons are highly specialised to transmit messages
from one part of your body to another.
nerve cells are called neurons as well.
