During the S1 phase of the cardiac cycle, the valve that closes first is the mitral valve. S1, also known as the first heart sound, occurs at the beginning of systole when the atrioventricular (AV) valves close.
The AV valves include the mitral valve (located between the left atrium and left ventricle) and the tricuspid valve (located between the right atrium and right ventricle).
The mitral valve closes slightly before the tricuspid valve due to the pressure differences between the left and right sides of the heart. The left ventricle, which pumps blood to the entire body, generates higher pressure compared to the right ventricle, which pumps blood to the lungs. As a result, the pressure in the left atrium rises more rapidly, causing the mitral valve to close first.
This valve closure is essential to prevent blood from flowing back into the atria during ventricular contraction (systole). Proper closure of the mitral and tricuspid valves ensures that blood is efficiently pumped out of the heart and into the circulatory system.

Screening programs using ___________ ____________ (TCD) measurement of flow velocities through the carotid circulation can identify children at high risk for stroke.
Screening programs using Transcranial Doppler (TCD) measurement of flow velocities through the carotid circulation can identify children at high risk for stroke.
Transcranial Doppler (TCD) is a noninvasive ultrasound technique that evaluates blood flow velocities in the major intracranial arteries, particularly the carotid arteries. These arteries are responsible for supplying oxygen-rich blood to the brain, and any blockage or abnormal blood flow can increase the risk of stroke.
TCD screening programs aim to identify children with a heightened risk of stroke by monitoring flow velocities within the carotid circulation. Elevated velocities may indicate narrowed or obstructed arteries, which can lead to inadequate blood supply to the brain and ultimately result in a stroke. Identifying high-risk children early allows for timely intervention and management, reducing the likelihood of severe neurological consequences.
These programs are particularly important for children with conditions known to increase stroke risk, such as sickle cell disease, congenital heart defects, or vasculopathies. By regularly monitoring blood flow through the carotid circulation with TCD, healthcare professionals can detect changes in flow velocities that may signify an increased risk of stroke. This early detection enables medical teams to implement preventive measures, such as medications, lifestyle modifications, or surgical interventions, to reduce the risk of stroke and improve overall outcomes for at-risk children.

Local anesthetics act like a ______ with sodium channels
Local anesthetics act like a "blocker" with sodium channels.
Local anesthetics function by temporarily numbing a specific area of the body, allowing medical procedures to be performed without causing pain or discomfort to the patient. The key mechanism through which local anesthetics work is by inhibiting sodium ion influx through voltage-gated sodium channels in the nerve cell membrane.
When the nerve is stimulated, sodium ions rapidly flow into the nerve cell, causing a change in the electrical potential across the cell membrane. This change, known as an action potential, leads to the propagation of a nerve impulse. Local anesthetics prevent this process by binding to the sodium channels and blocking the passage of sodium ions.
