Week 5 new Flashcards
What are the three main parts of the brain?
the cerebrum, cerebellum, and brainstem. The cerebrum, the largest part, is divided into right and left hemispheres. The brainstem controls functions necessary for life, including the cardiac and respiratory systems, and nerve function transmissions.
What does the brainstem control?
The brainstem controls functions necessary for life, including the cardiac and respiratory systems, and nerve function transmissions.
What is angina pectoris?
Angina pectoris occurs when myocardial oxygen demand exceeds supply.
What is aphasia?
Aphasia is a disorder that affects how you communicate; it can impact speech, writing, and the understanding of spoken and written language.
What is atherosclerosis?
Atherosclerosis is a disorder in which cholesterol and calcium build up inside the walls of blood vessels, forming plaque, which can lead to blockage of blood flow.
What is the atrioventricular node?
The atrioventricular (AV) node is a small structure in the heart, located in the Koch triangle near the coronary sinus on the interatrial septum.
What is cardiogenic shock?
Cardiogenic shock is caused by inadequate function of the heart, or pump failure, leading to a backup of blood into the pulmonary vessels.
What is the Cincinnati Prehospital Stroke Scale?
The Cincinnati Prehospital Stroke Scale (CPSS) is a validated screening tool that assesses facial palsy, asymmetric arm weakness, and speech disturbances.
What is a dissecting aortic aneurysm?
Aortic dissection is a life-threatening condition characterized by the tearing of the aortic wall, creating a false lumen that can compromise blood flow.
What is the foramen magnum?
The foramen magnum is a large opening at the base of the skull through which the brain connects to the spinal cord.
What occurs during a hemorrhagic stroke?
In a hemorrhagic stroke, blood from a ruptured blood vessel irritates the brain tissues and can cause increased intracranial pressure (ICP).
What is ischemia?
Ischemia is a condition where there is insufficient blood flow to tissues, often due to narrowing of the coronary arteries.
What is an ischemic stroke?
An ischemic stroke is characterized by acute onset of focal neurological deficits due to underlying cerebrovascular diseases.
What is left-sided heart failure?
Left-sided heart failure occurs when the heart loses its ability to pump blood, preventing organs from receiving enough oxygen.
What is right-sided heart failure?
Right-sided heart failure means the right side of the heart can no longer pump blood efficiently, causing fluid buildup in tissues.
What are the risk factors for ischemic and hemorrhagic strokes?
Common risk factors include high blood pressure, diabetes, and high blood cholesterol.
What is the sinoatrial node?
The sinoatrial (SA) node is the dominant pacemaker of the heart, generating electrical impulses that set the heart’s normal rhythm.
What is status epilepticus?
Status epilepticus is a neurological emergency defined as a seizure lasting 5 minutes or more or recurrent seizures without recovery.
What is the pathway of blood into and through the heart?
The pathway of blood into and through the heart was not found in the provided documents.
What is the treatment of a stroke?
Emergency medical services play a critical role in the assessment and management of suspected acute stroke patients.
What does nitroglycerin do?
Nitroglycerin relieves the pain associated with angina by dilating the arteries to increase oxygen supply to the heart muscle.
What do pulmonary arteries do?
The pulmonary artery carries oxygen-poor blood from the right ventricle to the lungs.
What do pulmonary veins do?
Pulmonary veins carry oxygen-rich blood from the lungs to the heart.
