The nerve impulse pathway of a voluntary action begins in the brain, where motor commands are generated in the motor cortex. These signals travel down the spinal cord through upper motor neurons, which synapse with lower motor neurons in the spinal gray matter. The lower motor neurons then send impulses through their axons to the skeletal muscles, causing contraction and movement. This entire process involves the integration of sensory feedback and coordination from various brain regions to execute the voluntary action smoothly.
What else can I help you with?
The neurotransmitters of a neutron enable a nerve impulse to do what?
Neurotransmitters in a neuron allow a nerve impulse to be transmitted from one neuron to another by crossing the synapse and binding to receptors on the receiving neuron. This triggers an electrical or chemical signal to continue the nerve impulse along the neural pathway.
How an impulse can continue to travel along a nerve pathway when there's a gap between two neurons?
An impulse can continue to travel along a nerve pathway when there's a gap between two neurons through a process called synaptic transmission. At the gap, known as a synapse, neurotransmitters are released by the sending neuron, which then bind to receptors on the receiving neuron, triggering a new electrical signal to continue the impulse along the nerve pathway.
How many directions can a nerve impulse travel in?
A nerve impulse can travel in two directions: towards the brain (sensory or afferent pathway) to convey sensory information, and away from the brain (motor or efferent pathway) to control muscle movement or glandular secretion.
If you accidentally step on a tack with your bare foot the pathway that the nerve impulse takes from your foot to your leg is called?
The pathway that the nerve impulse takes from your foot to your leg is called the sensory pathway. This pathway includes sensory neurons that carry signals from the foot to the spinal cord and then to the brain, where the sensation of pain is perceived and a motor response is initiated to move away from the tack.
How does a impulse continue to travel along the nerve pathway with a gap between 2 neurones?
An impulse continues to travel along a nerve pathway across the gap between two neurons, known as a synapse, through the release of neurotransmitters. When an action potential reaches the end of the presynaptic neuron, it triggers the release of these chemicals into the synaptic cleft. The neurotransmitters then bind to receptors on the postsynaptic neuron, leading to the generation of a new action potential in that neuron, thus propagating the impulse. This process allows for rapid communication between neurons despite the physical gap.
What pathway does a nerve impulse follow after initiated into a receptor?
nerve my a$$ nerve
What is a similarity between a reflex action and a voluntary action?
Both require motor neurones to carry the nerve impulse to the effector in order for the muscle to contract carry out an action.
Is a action potential necessary for a nerve impulse to occur?
Yes, an action potential is needed for a nerve impulse to occur.
Is an action potential necessary for a nerve impulse to occur?

What is nerve impulse transmission?
An action potention.

A nerve impulse consists of a wave of?
Action Potentials
