What impulse conduction is the fastest in neurons?
Axons conduct the nerve impulses. Dendrites receive the impulses. Possible the impulses go through the dendrites faster, though the synaptic cleft may slow this pathway. Dendrites are much shorter than axons.
The Krebs cycle is an example of which type of metabolic pathway?
The Krebs cycle is an example of an aerobic metabolic pathway, as it requires oxygen to function efficiently.
The simplest pathway able to receive a stimulus enter the central nervous system for immediate interpretation and produce a response is known as a?
reflex arc. This pathway consists of a sensory receptor, sensory neuron, interneuron in the spinal cord, motor neuron, and effector muscle or gland. It allows for quicker responses to potentially harmful stimuli without conscious brain involvement.
Which of the following does not factor into the rate of impulse propagation?
One factor that does not influence the rate of impulse propagation is the size of the neuron. The rate of impulse propagation is determined mainly by the myelination of the axon, the presence of nodes of Ranvier, and the diameter of the axon.
Where does the pentose phosphate pathway occur?
The pentose phosphate pathway occurs in the cytoplasm of cells. It is a metabolic pathway that generates NADPH and produces ribose-5-phosphate, which is important for nucleotide synthesis and other cellular processes.
What pathway does a nerve impulse follow after initiated into a receptor?
nerve my a$$ nerve
What is the name of the short pathway that carries the impulse for an automatic response?
The short pathway that carries the impulse for an automatic response is called a reflex arc. It involves sensory neurons, interneurons in the spinal cord, and motor neurons to quickly produce a reflex action in response to a stimulus, bypassing the brain.
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 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.
What is the correct pathway that the impulse takes through the ventricles?
The correct pathway that the impulse takes through the ventricles begins at the atrioventricular (AV) node, where it is briefly delayed before traveling to the bundle of His. From the bundle of His, the impulse branches into the right and left bundle branches that run along the interventricular septum. Finally, the impulse spreads through the Purkinje fibers, causing the ventricles to contract and pump blood out of the heart.
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.
What carries the nerve impulse from the central nervous system to an effector?
Nerve impulses are carried from the central nervous system to the effector organs (muscles or glands) by motor neurons. These motor neurons form a pathway known as the efferent pathway.
How does an impulse travel through the heart?
An impulse travels through the heart by moving from the sinoatrial (SA) node to the atrioventricular (AV) node, then through the bundle of His, the bundle branches, and finally to the Purkinje fibers. This pathway coordinates the contraction of the heart muscle, leading to a synchronized heartbeat.
In coronary conduction the electrical impulse is released at what level of the coronary electrical system?
With Wolff-Parkinson-White Syndrome, the heart has an extra nerve, or "accessory pathway" that electrically connects the _____ to the _____.
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.
The simplest pathway of an inpulse is what?
A simple reflex arc that only involves two neurons; these are usually found in the digestive system.
