Do bee's have a nervous system?
Yes, they do. However, a bee's nervous system is vastly different from those of vertebrates, such as humans. It consists of a brain at the head and several ganglia distributed throughout the body.
Is the medulla oblongata part of the limbic system?
The medulla oblongata is not part of the limbic system. If grouped, it is usually considered part of the brain stem. It is extremely crucial for survival as it controls the autonomic centers (involuntary things) like breathing, the heart, and the digestive organs.
What is a condition characterized by decreased efficiency of heart pumping?
Heart failure
How does stress affect your nervous system?
Answer this question… A. signals musculoskeletal system to cause rapid and uncontrollable movements B. signals digestive system to stop digesting food C. signals endocrine system to produce hormones to elevate heart and breathing rate D. signals the respiratory system to reduce the breathing rate
When heart rate is increased the time of ventricular filling is?
. . . decreased.
What type of action does negative chronotropes exhibit?
Decreased heart rate
Which of these is not a short-term effect of marijuana use?
Increased risk of chronic bronchitis.
What is a nursing diagnosis for Atrial Fibrillation?
Decreased Cardiac Output as evidenced by irregular heart beat, decreased ejection fraction and generalied edema.
Is pilocarpine an antagonist or an agonist?
Pilocarpine is actually a Muscarinic cholinergic receptor (mAChR) agonist. It works on the Parasypathetic nervous system; therefore, it makes sense that the agonist working on the PNS would result in decreased heart rate. Atropine, in contrast, is an muscarinic cholinergic receptor antagonist and will lead to increased heart rate due to the lowered effect of the parasympathetic system on the heart.
What is the effect of respiration on the heart sounds?
during inspiration, intrathoracic pressure is decreased.
What happened to the organism if the heart wers injured or disease?
Decreased capacity ... and/or death.
What is the normal compensatory response to a decreased cardiac contractility often seen in myocardial infarction?
Increase in heart rate as Cardiac Output = Heart rate x Stroke volume. As SV will be decreased, HR increases to compensate.
