What else can I help you with?
Voluntary muscles receive the singnal to contract or relax from thr brain people make the decision to make a movement and the signal is sent from the brain down through the?
nerve fibres
What is a signal that is sent from the brain and goes down?
A signal that is sent from the brain and travels down is typically a motor command. These signals originate in the motor cortex, where they initiate voluntary movements by sending electrical impulses through the spinal cord to peripheral nerves. This process enables communication between the brain and muscles, allowing for coordinated actions.
How does movement happen in your body?
Your brain (you) sends electrical messages to muscles through the nervous system, which makes certain muscles contract and make you move. Like when you lift your finger your brain sends a signal to a muscle in your arm which pulls the tenant that lifts it up. Also, sperm whale.
People make the decision to make a movement and the signal is sent from the brain through what?
People make the decision to move, and the signal is sent from the brain through the spinal cord and peripheral nerves. The brain processes information and generates motor commands, which travel down the spinal cord and out through motor neurons to the muscles, initiating movement. This complex communication allows for coordinated actions in response to various stimuli.
What is the path of a voluntary impulse?
The path of a voluntary impulse begins in the brain, where the decision to initiate movement is made. This signal travels down the spinal cord through motor neurons, which transmit the impulse to the relevant muscles. The muscles then contract in response, resulting in voluntary movement. This process involves several regions of the brain, including the motor cortex, which coordinates and executes the action.
How many muscles does it take to have a dream?
It takes 200 muscles to take one single step! Thats not really an answer... Really if the brain had any muscles i guess so. So no, because it is your brain shutting down temporarily. But other things like legs and muscles stay awake.
What is the fuction of the spinal cord?
the spinal cord help send signal down or up from the brain to the limbs
Where does a motor neuron send its message?
A motor neuron sends its message, in the form of an electrical signal called an action potential, to a specific muscle to stimulate contraction. This signal travels down the neuron's axon to its terminal branches, where neurotransmitters are released to activate the muscle fibers.
What is nerves used for?
They Transfer signals from the various places in your body to your brain to process and then to fire a signal back for them to shock the muscles into movement, without nerve signals you cant walk, which is why if you break your spine (the central nervos system) you are most likely to be dead from the waist down, or from the chin down depending where you break it.
How does your mouth chew?
You put food in your mouth and your brain tells your muscles to move your jaw bone up and down.
How does a neuron send a signal to communicate with other neurons or muscles?
A neuron sends a signal through an electrical impulse that travels down its long, slender body called an axon. When the impulse reaches the end of the axon, it triggers the release of chemical messengers called neurotransmitters. These neurotransmitters then cross the small gap between the neurons or between a neuron and a muscle cell, allowing the signal to be passed on to the next cell.
What relays information for muscles?
Sensory neurons carry signals from the receptors in our body (e.g. thermal, pressure etc.) to the relay neurons, which are found in our spinal cord. Relay neurons then send signals along the spinal cord to the brain. The brain then processes the information and sends a signal back down the spinal cord, through the relay neurons. Relay neurons then sends signals to motor neurons, which will then affect the muscles' movements.Read more: What_does_neuron_cells_do
