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.
Which structure delivers nerve impulse to the brain?
The nervous system delivers nerve impulses to the brain through specialized cells called neurons. These neurons transmit electrical signals from receptors in the body to the brain via neural pathways. The structures involved in this process include sensory receptors, peripheral nerves, the spinal cord, and the brain.
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.
How do auditory pathways carry nerve impulses to auditory cortices?
the auditory nerve pathways carry impulses to the auditory cortices in the ?
What is the precise amount of electrical pulses does the brain send the heart?
The brain does not send "electrical pulses" to the heart. Electrical impulses are actually generated within the heart itself (in the SA node), which travel through several intricate pathways from the atria down to the ventricles.
What cells stimulate both atria to contract?
The sinoatrial (SA) node, located in the right atrium, is responsible for initiating the electrical impulses that stimulate both atria to contract simultaneously. These electrical impulses spread through specialized conducting fibers called the internodal pathways to ensure coordinated atrial contraction.
The auditory nerve pathways carry impulses to the auditory cortices in the?
