class=\"has-large-font-size\"><strong>Nervous Cells (Neurons):<\/strong><\/p>\n\n\n\n<ol class=\"has-large-font-size wp-block-list\">\n<li><strong>Introduction:<\/strong><\/li>\n<\/ol>\n\n\n\n<ul class=\"has-large-font-size wp-block-list\">\n<li>Nervous cells, or neurons, are the fundamental building blocks of the nervous system.<\/li>\n\n\n\n<li>They play a crucial role in transmitting and processing information in our body.<\/li>\n<\/ul>\n\n\n\n<ol class=\"has-large-font-size wp-block-list\">\n<li><strong>Structure of Neurons:<\/strong><\/li>\n<\/ol>\n\n\n\n<ul class=\"has-large-font-size wp-block-list\">\n<li>Neurons have three main parts: cell body, dendrites, and axon.<\/li>\n\n\n\n<li>The cell body contains the nucleus and other essential organelles.<\/li>\n\n\n\n<li>Dendrites receive signals from other neurons or sensory receptors.<\/li>\n\n\n\n<li>The axon is a long, slender projection that carries signals away from the cell body.<\/li>\n<\/ul>\n\n\n\n<ol class=\"has-large-font-size wp-block-list\">\n<li><strong>Function of Neurons:<\/strong><\/li>\n<\/ol>\n\n\n\n<ul class=\"has-large-font-size wp-block-list\">\n<li>Neurons transmit electrochemical signals called nerve impulses or action potentials.<\/li>\n\n\n\n<li>These impulses allow communication between different parts of the nervous system.<\/li>\n\n\n\n<li>Neurons enable us to think, perceive, move, and feel.<\/li>\n<\/ul>\n\n\n\n<ol class=\"has-large-font-size wp-block-list\">\n<li><strong>Types of Neurons:<\/strong><\/li>\n<\/ol>\n\n\n\n<ul class=\"has-large-font-size wp-block-list\">\n<li>Sensory Neurons: Transmit sensory information from sensory organs to the central nervous system (CNS).<\/li>\n\n\n\n<li>Motor Neurons: Carry signals from the CNS to muscles and glands, controlling movements and responses.<\/li>\n\n\n\n<li>Interneurons: Found within the CNS, they relay signals between sensory and motor neurons.<\/li>\n<\/ul>\n\n\n\n<ol class=\"has-large-font-size wp-block-list\">\n<li><strong>Synapses:<\/strong><\/li>\n<\/ol>\n\n\n\n<ul class=\"has-large-font-size wp-block-list\">\n<li>Neurons communicate at junctions called synapses.<\/li>\n\n\n\n<li>Neurotransmitters are chemicals that transmit signals across synapses.<\/li>\n\n\n\n<li>This process allows for information to be transferred from one neuron to another.<\/li>\n<\/ul>\n\n\n\n<ol class=\"has-large-font-size wp-block-list\">\n<li><strong>Importance of Neurons:<\/strong><\/li>\n<\/ol>\n\n\n\n<ul class=\"has-large-font-size wp-block-list\">\n<li>Neurons are essential for basic bodily functions, such as breathing and reflexes.<\/li>\n\n\n\n<li>They are also responsible for complex cognitive processes like thinking, learning, and memory.<\/li>\n<\/ul>\n\n\n\n<ol class=\"has-large-font-size wp-block-list\">\n<li><strong>Protection of Neurons:<\/strong><\/li>\n<\/ol>\n\n\n\n<ul class=\"has-large-font-size wp-block-list\">\n<li>Neurons are delicate cells and need protection.<\/li>\n\n\n\n<li>They are surrounded by a protective layer called the myelin sheath, which speeds up signal transmission.<\/li>\n\n\n\n<li>The skull and spine protect neurons in the brain and spinal cord.<\/li>\n<\/ul>\n\n\n\n<ol class=\"has-large-font-size wp-block-list\">\n<li><strong>Neurological Disorders:<\/strong><\/li>\n<\/ol>\n\n\n\n<ul class=\"has-large-font-size wp-block-list\">\n<li>Disorders related to neurons can have a significant impact on health.<\/li>\n\n\n\n<li>Examples include Alzheimer&#8217;s disease, Parkinson&#8217;s disease, and multiple sclerosis.<\/li>\n<\/ul>\n\n\n\n<ol class=\"has-large-font-size wp-block-list\">\n<li><strong>Conclusion:<\/strong><\/li>\n<\/ol>\n\n\n\n<ul class=\"has-large-font-size wp-block-list\">\n<li>Nervous cells (neurons) are the basic units of the nervous system.<\/li>\n\n\n\n<li>They are responsible for transmitting and processing information that controls our body&#8217;s functions and behaviors.<\/li>\n<\/ul>\n\n\n\n<p class=\"has-text-color
