The trigger zone of a neuron includes?
The axon hillock and the initial segment
What part of the brainstem that receives information from the chemoreceptor trigger zone?
Medulla Oblangota
Excruciating facial pain upon stimulation of a trigger zone?
Bootje patrick...bootje
What is the trigger point at which a neuron will fire called?
Its where there are a lot of sodium channels. Once the trigger zone is 'triggered' to threshold (from -70mV to -55mv), then an action potential occurs. trigger zone in MOTOR neurons are in the axon hillock and in SENSORY neurons, they're in the 1st unmyelinated area (first node of ranvier).
The vomiting reflex is mediated by the?
No. The vomiting reflow is mediated by the chemoreceptor trigger zone (CTZ) in the medulla of the brainstem, which communicates with the vomiting center (to mediate the vomiting reflex)
Disturbances when will sensory neurons result in an action potential?
if the graded potential of threshold size reaches a trigger zone
How does the plasma membrane at the trigger zone differ from that on the soma?
The plasma membrane has voltage gated channels whereas the soma does not.
What is chemoreceptor trigger zone?
The chemoreceptor trigger zone is a bilateral set of centers in the brainstem lying under the floor of the fourth ventricle.CTZ has connection with vomiting center and play indirectly to stimulate vomiting.. Electrical stimulation of these centers does not induce vomiting, but application of emetic drugs does - if and only if the vomition centers are intact. The chemoreceptor trigger zones function as emetic chemoreceptors for the vomition centers - chemical abnormalities in the body (e.g. emetic drugs, uremia, hypoxia and diabetic ketoacidosis) are sensed by these centers, which then send excitatory signs to the vomition centers. Many of the antiemetic drugs act at the level of the chemoreceptor trigger zone.
Vomiting reflex is mediated by the?
Chemoreceptor trigger zone (CTZ) in the medulla of the brainstem, which communicates with the vomiting center (to mediate the vomiting reflex).
Was mount redoubt caused by an earthquake?
No. Mount Redoubt was formed by a subduction zone. While in som cases earthquakes can trigger volcanic eruptions, they do not cause volcanoes to form.
What are type of trigger?
*static trigger *dynamic trigger *hold trigger
What is the site of action in the brain where antipsychotics work?
Thes are the sites of action in the brain where antipsychotics work. The Basal ganglia, areas of the limbic system, the chemoreceptor trigger zone ,and the cerebral cortex
