Answer:
The correct answer is -Serotonin receptor agonists such as Imitrex are effective in the acute treatment of migraines.
Explanation:
Norika is experienced a headache with evident nausea and visual disturbances which suggests that she has symptoms of acute migraines, In acute migraines, the doctor advises getting serotonin receptor agonist injections as these activate receptors similarly serotonin do.
The correct answer is -Serotonin receptor agonists such as Imitrex are effective in the acute treatment of migraines.
Answer:
It is the cardiac output.
Explanation:
Heart rate x stroke volume = cardiac output.
The cardiac output is the final outcome of all factors that influentiate the ventricular activity (heart rate, heart contractility, and the phenomenon of precharge and postcharge).
The basolateral complex has dense connections with a variety of sensory areas of the brain. It is critical for classical conditioning and for attaching emotional value to learning processes and memory.
Answer:
D. Decreasing vessel diameter
Explanation:
Cardiac output is the amount of blood pumped per unit time by heart. Increased cardiac output corresponds to increased blood pressure which will result in increased blood flow. In vasodilation the smooth muscles within the blood vessels relax making them wide hence decreasing vascular resistance leading to more blood flow. Decreased blood viscosity will also decrease the resistance to blood flow.
Decreasing vessel diameter will not increase the blood flow, it will rather restrict it because there will be more resistance to passage of blood due to small space.
Answer:
The correct answer is D.
Explanation:
Papillary muscles, attached via chordae tendineae, help to close the valves and prevent regurgitation.
Pectinate muscles are parallel ridges in the walls of the atrium of the heart, mainly in right atrium. They can stretch during adverse loading conditions, to <em>help the right atrium to dilate without much wall stres</em>s.
