Is craniosacral division another name for the parasympathetic division?
True
What are similarities between the sympathetic and parasympathetic nervous system?
Question is short but answer is bit long. Parasympathetic system is meant for to to maintain the homeostasis and body building. Sympathetic system is meant to give you ' Fight or flight response. So you have pupils constricted in parasympathetic and dilated in sympathetic response. You need not see towards the world during first and need to look at the world carefully in danger. Secretions of gastrointestinal system are increased, peristalsis is increased, spinctures are opened up during stimulation of the parasympathetic system. This helps in digestion and body building. Vise verse is true with sympathetic system. During stimulation of the sympathetic system your cardiovascular system is on the toes, to supply more blood to muscles. So the heart rate is increased, stroke volume is increased ans as a result you have great increase in cardiac output. So cardiac output may go to 25 litres / minute from 5 litres / minutes. Blood vessels to muscles are dilated, so that almost 20 litres blood goes to muscles. Net increase from 0.5 litres to 20 litres / minute. In respiratory system you have bronchial system dilated to provide more oxygen to lungs in sympathetic stimulation, the bronchial secretions are less in amount and respiratory rate increases to high level. Vise verse is true with parasympathetic system, when you are resting and need less of the oxygen. In parasympathetic system you have contraction of urinary bladder and relaxation of the spincture to void the urine. During stress you have no time for urination and reverse is true. Erection of penis is managed by parasympathetic system and ejaculation is done by sympathetic system.
Do both parasympathetic and sympathetic nervous systems operate with a chain of two motor neurons?
True
Is acetylcholine the substance released by the axon terminals of both somatic motor neurons and postganglionic parasympathetic neurons?
True
True or false an object in free fall accelerates until it reaches terminal velocity?
True. Got that right on a test :)
Production of the high-energy terminal phosphate bond of ATP depends on oxygen?
true
Is acetylcholine the substance released by axonal endings of the somatic efferent fibers and by the parasympathetic nerve fiber endings?
Yes, it does. In contrast, the sympathetic nerves release adrenaline
What is the major difference between simple and complex nervous systems?
simple-> doesnt coordinate activities unless there is a ganglia complex -> has a true brain with sensory structure that coordinates acitivties efficiently
What 2004 movie was based on the true story of merhan karimi nasseri who had been living in Paris at terminal one of Charles de gaulle airport since 1988?
The Terminal
Are Ovals used as terminal symbols marking the starting and end of the pseudocode?
No that would be a flowchart.
True or false it is impossible for the electrons in a battery to travel form the positive to negative terminal?
false
Is conventional flow or electronic flow true?
Electronic flow is true. Conventional flow was thought to have positive charges flowing from the + terminal to the - terminal. This was before we knew that it is actually the electrons which flow, and the positive charges cannot move out of their atomic nuclei. Now that electrons have been detected, and protons are known to stay within the nucleus unless a nuclear reaction takes place, we know that it is the electrons that flow from the - terminal to the + terminal. This is known as electronic flow.
