How many types of specialized cells are there in the human body?
There are over 200 different types of specialized in the human body. Specialized cells are important because they carry out specific functions that allow the body to maintain homeostasis.
What Does It Mean for a Cell to Be Specialized?
If a cell is specialized, it has unique structures that allow it to carry out its function in the body. All cells start as stem cells, which are cells that can become many other types of cells. They go through a process called differentiation to become specialized. During differentiation, different environmental cues trigger changes in protein synthesis inside the cell. Different genes are turned on or off through gene regulation; this creates different proteins, and thus structure and function for the cell.

Neurons are specialized cells of the nervous system.
What are some examples of cells specialized for reproduction?
Sperm and eggs are examples of cells specialized for reproduction.
Why are neurons different from skin cells?
However, neurons in our brain are very different from skin cells because neurons turn on genes needed for their job and thus make neuronal proteins, and skin cells turn on epithelial genes to make proteins required for their job.
What are the functions of nerve cells?
Nerve cells are cells that can conduct electrochemical impulses. These cells form the nervous system. Neurons have several essential structures that allow them to do their job. The main part of the cell is called the cell body, and it contains the nucleus and other vital organelles. The cell body has projections called dendrites that receive information from other cells. On the other end of the cell body is a single axon. The axon carries information from the cell body to the terminal. The axon is highly specialized for the electrical transmission of information. It is filled with ion channels that allow the electrical signal, called an action potential, to travel down the length. At the terminal, the electrical signal converts to a chemical signal, called neurotransmitters. The neurotransmitters are released into the space just outside the terminal and can send messages to other neurons and effector organs.
What are the two types of reproductive cells?
Reproductive cells are those used for sexual reproduction. There are two main types of reproductive cells, sperm, and eggs . Sperm cells are specialized to have a shape that allows them to be aerodynamic and swim through the reproductive tract to fertilize an egg. They are also packed with mitochondria to provide the energy necessary to power the flagella for swimming. Egg cells are specialized to contain the organelles needed for a new cell to form after fusion.
Why are cells specialized?
Cells become specialized so that they can perform a set of particular roles or functions, playing their part in reproduction, energy metabolism, regeneration, information transfer, etc. One of the fascinating areas of study about the human body is cell biology.

What is cell specialization?
That's where cell specialization comes in. Cell specialization allows new cells to develop into a range of different tissues, all of which work together to make living organisms function as a whole. The process of cell specialization – exactly how cells develop into their diverse forms – is complex.
What are the four categories of cells?

What Kind of Specialized Tissues Are There in the Body?
While scientists know the human body contains trillions of cells, exactly how many cell types make up the body is still an active field of study. The most recent estimate notes that there are at least 200 unique cell types in the human body, at least based on appearance. Some scientists think that estimate is low, though, and new cell types are still being discovered regularly.
How does the stem cell know if you need more red blood cells?
It sends a signal to your blood stem cells that you need more red blood cells. This signal is received on the cell's surface. The stem cell transmits (or transduces) that message to the nucleus, so the cell knows your body needs more red blood cells.
How are stem cells separated?
There are different types of stem cells, separated by how many tissues they can develop into. The stem cells found in an embryo, for instance, can develop into any tissue type – which is how you go from a single stem cell to a fully formed human baby.
Why are stem cells unique?
Stem cells are a unique type of cell, because, while they're immature cells without any specialization, they can follow a developmental "blueprint" to develop into the thousands of unique cell types found throughout your body. There are different types of stem cells, separated by how many tissues they can develop into.
