Do nerve impulses travel down the internodal pathways from the av node?
No, nerve impulses travel down the internodal pathways towards the AV node, not from it. The internodal pathways conduct the impulse from the SA node to the AV node, assisting in the synchronization of the heart's electrical activity.
What is the correct order of stimulation in the nodal pathways?
The correct order of stimulation in the nodal pathways is: 1. Sinoatrial (SA) node generates electrical impulses 2. Atrioventricular (AV) node delays the impulses 3. Bundle of His conducts the impulses to the bundle branches and Purkinje fibers for ventricular contraction.
What are the routes followed by nerve impulses as they pass through the nervous system?
Nerve impulses travel in one direction along a neuron, from the dendrites, through the cell body, down the axon, and finally to the axon terminals. At the axon terminals, neurotransmitters are released to communicate with the next neuron or target cell. This process allows the nerve impulse to pass through the nervous system efficiently.
If Impulse from the eye result in sight perception and impulses from the ear are perceived as sound due to?
Impulses from the eye are processed by the brain to create the sensation of sight, while impulses from the ear are processed to create the sensation of sound. These sensory perceptions are the result of complex neural pathways in the brain that interpret and make sense of the information received from the eyes and ears.
Are the impulses traveling to the thalamus afferent or efferent?
Impulses traveling to the thalamus are afferent. Afferent pathways carry sensory information from the peripheral nervous system to the central nervous system, including the thalamus, for processing. Efferent pathways, on the other hand, carry motor commands from the central nervous system to the peripheral nervous system for action.
How do auditory pathways carry nerve impulses to auditory cortices?
the auditory nerve pathways carry impulses to the auditory cortices in the ?
What is slowest conduction velocity?
The slowest conduction velocity occurs in unmyelinated C fibers, which are responsible for transmitting dull, aching pain signals in the body. These fibers conduct nerve impulses at a speed of around 0.5 to 2 meters per second.
Do nerve impulses travel down the internodal pathways from the av node?
No, nerve impulses travel down the internodal pathways towards the AV node, not from it. The internodal pathways conduct the impulse from the SA node to the AV node, assisting in the synchronization of the heart's electrical activity.
The auditory nerve pathways carry impulses to the auditory cortices in the?
Temporal lobes.
What is the correct order of stimulation in the nodal pathways?
The correct order of stimulation in the nodal pathways is: 1. Sinoatrial (SA) node generates electrical impulses 2. Atrioventricular (AV) node delays the impulses 3. Bundle of His conducts the impulses to the bundle branches and Purkinje fibers for ventricular contraction.
Nerve impulses trAVel down the internodal pathways from the AV node?
No, SA Node
What are the three pathways, including the alternative, classical, and lectin pathways, that activate the immune system's response to what?
The three pathways that activate the immune system's response are the alternative, classical, and lectin pathways. They work together to recognize and respond to foreign invaders, such as pathogens or damaged cells, in the body.
What nerve routes are followed by nerve impulses passing through the nervous system?
nerve pathways
What is the difference between afferent and efferent pathways?
The major difference is the direction of travel for nerve impulses. In the afferent nervous system, the impulses are traveling away from the brain - these tend to be motor impulses. In the efferent nervous system, the impulses are traveling towards the brain - these tend to be sensory impulses.
What does carbamazepine do?
drug decreases abnormal electrical impulses through nerve cell pathways by inhibiting the activity of sodium channels in neurons. Consequently, it blocks the repetitive impulses that trigger seizures.
Do ascending pathways conduct sensory impulses upward through three levels or orders of neuron groups?
True
Describe the pathways that the nerve impulses take one suffers a burned finger and reacts to it.?
