what is the nervous system quickly adjusts blood flow by directly controlling

Expert Solution

Answer- Our nervous system adjusts blood volume and blood flow in following manner-

The cardiovascular center forms part of the autonomic nervous system and is responsible for regulation of cardiac output. It is located in the medulla oblongata. The cardiovascular center contains three distinct components-

The cardioaccelerator center, the cardioinhibitor center, and the vasomotor center.

The vasomotor center controls vessel tone or contraction of the smooth muscle in the tunica media. Changes in diameter affect peripheral resistance, pressure, and flow, which in turn affect cardiac output. The majority of these neurons act via the release of the neurotransmitters.
The cardioaccelerator center stimulates cardiac function by regulating heart rate and stroke volume via sympathetic stimulation from the cardiac accelerator nerve.
The cardioinhibitor center slows cardiac function by decreasing heart rate and stroke volume via parasympathetic stimulation from the vagus nerve.

When there is a blockage of the blood flow or a hemorrhage that affects the nervous tissue, the result is what we know as a cerebrovascular accident (CVA) or stroke. Discuss what would be the result, depending on the area that is affected. For example, what happens if it occurs in the occipital lobe, or if there is a difference if it occurs in the left or right frontal lobe, etc.

Explain how the sympathetic nervous system (and endocrine system) act directly to regulate heart rate and thus cardiac output. Include a detailed description of the mechanism (include the target cells, the proteins, signaling molecules, ions, and changes in membrane pontial where appropriate) and explain how the mechanism operates to alter heart rate.Explain how the parasympathetic nervous system acts to directly regulate cardiac output (1 mechanism). Discuss each mechanism separately including a detailed description of each mechanism (include the target cells,...

1.The central nervous system (CNS) is composed of billions of discrete cells that are not directly connected but are instead connected by synapses, which require neurotransmitters to pass a signal between cells. Why is this an advantage over a CNS in which all the cells are directly connected? That is, what do we gain by having our brains made up of individual cells that don’t automatically fire an action potential when they are stimulated? What are the drawbacks of the...

Communication by the nervous system depends on the flow of information through chains of neurons that are functionally connected by synapses. The most common synapse in the human body is the chemical synapse. Define chemical synapse. 3 points Describe the chain of events that occur at a chemical synapse. (HINT: Your answer should begin with an action potential arriving at an axon terminal.) 5 points What events account for the synaptic delay? 2 points Give one example of a chemical...
