The human nervous system is made up of two distinct categories: the central nervous system, which is made up of the brain and the spinal cord, and the peripheral nervous system, which is made up of a massive network of nerves that branch off the spinal cord and extend throughout our entire bodies.
The central nervous system consists of two main parts: the brain and the spinal cord. Let’s dive a little bit deeper into each of these sections:
The second part of the human nervous system is the peripheral nervous system. The peripheral nervous system is made up of two parts: 1. Somatic Nervous System 2. Autonomic nervous system
The entire human nervous system is built on the back of a specialised type of cell called a neuron. As you can see in this diagram, neurons have a long, tail-like extension called an axon, and they end in tiny branching protrusions called dendrites. These two parts allow neurons to communicate with each other, even over long distances. Big bundles ...
Let's start off by explaining how messages travel between our neurons, allowing messages to travel throughout the body. When a neuron sends a message to another neuron, it sends an electrical signal down the length of its axon. At the end of the axon, the electrical signal changes to a chemical signal. The axon then releases the chemical signal wit...
The nervous system plays a vital role within the body since it effectively controls everything that happens within the body. The brain coordinates all our bodily functions from breathing, to movement, to complex activities like solving complicated mathematics puzzles. The network of nerves both carries information and instructions from the brain to...
The nervous system enables humans to react to their surroundings and to coordinate their behaviour. It comprises millions of neurones and uses electrical impulses to communicate very quickly.
There are two main types of nerves: sensory nerves and motor nerves. Sensory nerves handle information relating to the senses. They send information from the eyes, ears, mouth, nose, skin, and other body parts to the spinal cord and brain. Motor nerves carry messages in the other direction.
A. negative feedback. mechanism is an important type of control that is used in homeostasis. A negative feedback control system responds when conditions change from the ideal or set point and...
Neuromodulation is the physiological process by which a given neuron uses one or more chemicals to regulate diverse populations of neurons. Neuromodulators typically bind to metabotropic, G-protein coupled receptors (GPCRs) to initiate a second messenger signaling cascade that induces a broad, long-lasting signal.
Whenever you dream, laugh, think, see or move, it’s because minute chemical and electrical signals are racing between these neurons along billions of tiny neuron pathways. Incredibly, the activity in your brain never stops.
