All About Nerves

-

Nerves:

Your entire body is covered in nerves. Nerves transmit electrical signals that enable you to move your muscles and sense sensations. Additionally, nerves regulate bodily processes including digestion and heart rhythm. One of the fundamental components of your neurological system are nerves.

Your brain sends electrical impulses to the rest of your body through your nerves, which act as cables. You can stretch your muscles and feel feelings thanks to these impulses. Additionally, they continue to carry out some autonomic processes includes sweating, breathing, and food digestion.



What are Neurons:

Neurons are another name for nerve cells. The human body contains neurons, particularly in the brain and spinal cord. Your nervous system is built on the foundation of your nerves, brain, and spinal cord. While doctors speak of the "nerve," they typically mean the portion of your nervous system that is not connected to your brain and spinal cord. Your peripheral nervous system is what it is known as.

Types of Nerves:

Your nerves fall into two categories:

Your brain receives information from your sensory nerves, which enable you to sense touch, smell, and taste as well as and see.
Your muscles or glands receive instructions from your motor nerves to help you move and function.

Consequently, your brain and spinal cord have two primary groupings of nerves that branch out:

Cranial nerves:

Twelve sets of cranial nerves travel from your brain via your face, head, and neck. Cranial nerves may serve sensory, motor, or both functions. For instance, cranial nerves support your ability to move your eyes, make movements of the face, and process odours.

Spinal nerves: 

31 pairs of spinal nerves branch out from your spinal cord, making up your spine. These nerves may facilitate motor, sensory, or combined functions. For instance, spinal nerves may send signals to your spinal cord from your joints and muscles. Involuntary actions like moving your hand away from a hot stove are likewise governed by spinal nerves.
