Cell Nucleus
The cell membrane also has tiny extensions called nanotubes that reach out to neighboring cells. Nanotubes are one way that cells communicate with each other. Cells also communicate through the chemical signaling of neurotransmitters and hormones.
Cell Membrane

At the center of the cell is its control center, the nucleus. The boundary of the nucleus is a double nuclear membrane barrier called the nuclear envelope that controls what gets into and comes out of the nucleus.
Cells are the basic unit of life Jordan 5 V, and research into cell biology continues to shed light on the structure and function of human cells.
Between the cell membrane and the nucleus is the cytoplasm, which consists of:
Although the human body contains many different types of cells (nerve cells, muscle cells, blood cells air jordans 13, T-cells, etc.), the basic underlying structure and function of all human cells are the same. Cells have a membrane, cytoplasm, and nucleus.
The cell membrane (also called the plasma membrane) is a double layer of lipids (fats) that forms the boundary of the cell. The membrane provides the structural integrity that holds the cell together. The function of the cell membrane is communication - it regulates the movement of water, nutrients, and wastes into and out of the cell.
The organelles of a cell include the following:
The nucleus contains a network of threads called chromatin, which contains the body's genetic material (DNA). The nucleus also contains dense spherical bodies called nucleoli (usually one or two). Nucleoli produce ribosomes, which are needed to translate genetic information into proteins.
Human Anatomy and Phys
The cell membrane contains receptors, a large and diverse group of integral proteins and glycoproteins that serve as binding sites for neurotransmitters, hormones, and other substances. These substances affect the cell's activity, and problems with cell receptors can lead to illness. Also, many drugs work by binding with cell receptors. Some illicit drugs bind with receptors, blocking the substances that should be binding with the receptors.

Cell Cytoplasm
Cells are the basic building blocks of the human body. Cells come together in groups called tissues, and tissues combine to form organs. How many cells does the human body contain? Trillions. A mere ten thousand cells can fit onto the head of a pin.
Mitochondria produce energy (adenosine triphosphate [ATP]).Ribosomes produce proteins from amino acids.Rough endoplasmic reticulum transports materials within the cell.Smooth endoplasmic reticulum synthesizes lipids and steroids, metabolizes lipids, and detoxifies drugs.Golgi apparatus packages, modifies, and separates proteins.Lysosomes are sites of digestion within the cell.Peroxisomes are enzymes for detoxification.Microfilaments are involved in movement within the cell.Intermediate filaments help stabilize the cell.Microtubules support the cell and give it shape.Centrioles participate in cell division.Cilia move substances across cell surfaces.Flagella propel the cell. The only human cell that has flagella is sperm.
