Facts about nerve cells will inform you about the primary components
of the nervous system. Nerve cells are also known as neurones or neurons. They are cells that carry messages through an electrochemical process around your body. The shape of nerve cells are different with the other cells because they have unusual parts named dendrites and axons, which are used to send messages. The messages consist of information about what’s happening. Then, the nerve cells will help human to respond in the right way. Here are ten interesting facts about nerve cells.
Facts about Nerve Cells 1: How many nerve cells in the human brain?
The amount of nerve cells in the human brain is more than the amount of stars in the Milky Way. Approximately, there are around 100 billion nerve cells in a person. Whereas the length of nerve cells in the body is around 965 km long.
Facts about Nerve Cells 2: Synapse
Synapse is a small gap which is located between two neurons. It help neuron to talk to another neuron. The neurotransmitters (chemicals) are sent into the synapse by neuron. Then the other neuron will pick them up. After that, the neurotransmitters will be changed into an electrical signal.
Facts about Nerve Cells 3: Types of Neurons by connection
There are three types of Neurons by connection, named afferent neurons, efferent neurons, and interneurons. The information from tissues and organs are carried by Afferent neurons into the central nervous system. Whereas the signals are carried by Efferent neurons from the central nervous system to the effector cells.
Facts about Nerve Cells 4: The parts of Neurons
There are three parts of neuorons: cyton, axon, and dendrites.
Facts about Nerve Cells 5: Cyton
The shape of cyton looks like a star. It has nucleus and cytoplasm.
Facts about Nerve Cells 6: Dendrites
Dendrites and axons are nerve fibres.
The shape of dendrites look like roots which are growing out of the cell body. They are smaller than axons. However, there are many dendrites in each neuron. Besides, the electrical messages are brought by them into the nerve.
Facts about Nerve Cells 7: Axon
The shape of axon looks like a long stem which is growing off of the cell body. Approximately, there is only one axon in a neuron. The function of axon is to bring electrical messages away from the nerve cell body.
Facts about Nerve Cells 8: Types of Neurons by function
There are three basic neuron types. They are Interneuron (Bipolar), Sensory Neuron (Unipolar), and Motoneuron (Multipolar). Connecting neurons to the other neurons in neural networks is the function of Interneuron. Whereas the function of Motor neurons is to receive signals from the brain and spinal cord. Furthermore, Sensory neuron responds the stimulus of sound, touch, light, and more.
Facts about Nerve Cells 9: The unique neuronal types
Basket cells, Betz cells, Lugaro cells, Medium spiny neurons, Purkinje cells, Pyramidal cells, Renshaw cells, Unipolar brush cells, Granule cells, Anterior horn cells, and Spindle cells are some examples of the unique neuronal types.
Facts about Nerve Cells 10: Neurological disorders
Charcot–Marie–Tooth disease, Alzheimer’s disease, Parkinson’s disease, Myasthenia gravis belong to Neurological disorders.
