Nerve impulses from the brain travel down the spinal cord to the rest of the body. The spinal cord is a long, thin, white cord that runs down the back. It is made up of nerve tissue and is covered by a thin membrane. The spinal cord attaches to the brain at the brainstem and runs down the back to the tailbone. The spinal cord carries messages between the brain and the rest of the body.

What does a nerve impulse travel down?
The nervous system is a complex network of cells and tissues that carries messages between the brain and the rest of the body. The messages, called nerve impulses, travel down the nerves to the muscles and organs.
Nerve impulses are created when the brain sends a message to the muscles or organs. The message is carried down the nerve by a chemical called a neurotransmitter. When the neurotransmitter reaches the end of the nerve, it causes the nerve to fire, or send a message to the muscles or organs.
The speed of a nerve impulse depends on the type of nerve. The fastest nerves are the ones that carry messages from the brain to the muscles. These nerves are called motor nerves. The slowest nerves are the ones that carry messages from the skin to the brain. These nerves are called sensory nerves.
Nerve impulses can travel at speeds of up to 250 miles per hour. However, the average speed is about 20 miles per hour.
Where does the nerve impulse travel?
Where does the nerve impulse travel?
The nerve impulse travels down the neuron, across the synapse, and then up the next neuron.
What is the pathway for impulses traveling to and from the brain?
The pathway for impulses traveling to and from the brain is a complex system of communication that relies on the coordinated function of many different parts of the body. This system is responsible for transmitting messages between the brain and the rest of the body, allowing us to interact with the world around us.
The pathway for impulses starts at the brain, where messages are transmitted as electrical impulses. These impulses travel through the spinal cord, which acts as a kind of communication hub, routing messages to the right places throughout the body. From the spinal cord, impulses travel to the muscles, where they cause us to move. They also travel to the organs, where they control the function of our internal systems.

Where do nerve impulses travel in the axon?
Nerve impulses travel in the axon from the neuron’s cell body to its terminal buttons. The axon is a long, slender extension of the neuron that carries the nerve impulse away from the cell body. The impulse travels down the axon to the terminal buttons, where it is transmitted to the next neuron.
How do nerve impulses travel across the synapse?
Nerve impulses travel across the synapse by way of neurotransmitters. When a neuron is activated, it releases neurotransmitters into the synaptic cleft. These neurotransmitters bind to receptors on the postsynaptic neuron, causing the postsynaptic neuron to fire.
What direction do sensory neurons travel?
Sensory neurons travel from the periphery of the body to the central nervous system. They relay information about the environment and the body to the brain. There are different types of sensory neurons, each specializing in a different type of information.
How do nerve signals travel up and down the spinal cord?
Nerve signals travel up and down the spinal cord through a process called conduction. This occurs when an electrical impulse is created by a neuron in the brain or spinal cord and travels down the axon to the nerve endings. When the impulse reaches the end of the axon, it causes the release of a chemical called a neurotransmitter. This neurotransmitter crosses the gap between the neuron and the next neuron, and the impulse is then passed on.
