Explain the difference between sympathetic and parasympathetic reactions as they occur in the autonomic nervous system?
The sympathetic nervous system is most active when you are in an emergency, exercising, or an exciting or embarrassing situation. It is often referred to as the "fight-or-flight" system. It increases the heart rate, blood pressure, and blood glucose levels. It also dilates the bronchioles of the lungs, and dilates the blood vessels of the skeletal muscles. This nervous system enables the body to cope rapidly with situations. The parasympathetic nervous system is active when the body is resting. It is referred to as the "resting-and-digesting" system. It conserves your body's energy by slowing the heart rate. It also promotes digestion.sypmathetic is the "fight or flight" response and the parasympathetic is the "rest and digest" responses
When does the first cell division in meiosis occur?
When the chromosome is :
What might occur in a leukemia cell that does not occur in a normal cell?
regulation in cell division and growth is stopped
What is the result of parasympathetic stimulation of the SA node?
Action potentials will occur less often due to an increase in the membranes permeability to K+
When does the second mitotic division occur in the egg?
after the first and before the third
Is sympathetic active after you have eaten a meal?
Unless some other factor (e.g., a bear trying to attack you) activates your sympathetic nervous system, the parasympathetic, not the sympathetic, nervous system is active after eating. Parasympathetic activation results in a decline of the stress hormones epinephrine and norepinephrine, which allows blood to be directed towards the digestive system so that digestion and absorption of nutrients can occur. When the sympathetic nervous system is activated, blood is diverted from the "non-essential" organs, such as the digestive system, and towards the heart, brain, and muscles.
What is another name for craniosacral division?
Parasympathetic part of autonomic system. It is also called the craniosacral division because the preganglionic neurons occur in the brainstem and sacral regions. Similarly, the sympathetic part of autonomic system also called the thoracolumbar division because the preganglionic neurons occur in the thoracic and lumbar segments of the body.

If your body starts to feel relaxed what part of the nervous system is becoming more active?
Parasympathetic nervous system helps your body start to feel relaxed as your nervous system becomes more active.
Compare between sympathetic and parasympathetic in reflex arc?
In parasympathetic reflex arc the preganglionic nerve fibre is longer than post ganglionic fibre, that is the synapse occur near the organ or tissue. While in sympathetic reflex arc both the pre and post have moderate sizes. The postganglionic fibre of parasympathetic always secrete acetylcholine as nuerotransmitter while postganglionic fibre of sympatheic reflex arc mostly secrete norepinephrine or epinephrine as nuerotransmitter. Some nerve fibres may secrete acetylcholine. For example postganglionic sympatehtic nerve fibres of sweat glands, pilorectal muscles and few blood vessels
Why mitotic cell division is called homotypic cell division?
Mitotic cell division is called homotypic cell division because no crossing over is occur in this division and pairing of homologous cromosome is also not occur. So caracteristics of daughter cells is same as mother cell. As there is no variation occur, so this type of cell division may called homotypic cell division.
When does cellular division occur?
m
What problems occur in reproduction?
Reduction division
What does uncontrolled cell division occur in?
cancer
Can bradycardia and hypertension occur concurrently?
Yes. In the Cushing's reflex, which is due to traumatic head injury resulting in an increased intracranial pressure, the body exhibits what is called the CNS ischemic response. This response is due to activation of both the sympathetic nervous system (which constricts veins and arterioles to increase both peripheral resistance and increase venous return to the heart) and the parasympathetic nervous system (which acts to slow the heart rate by overriding sympathetic stimulation on the heart). This results in a concurrent bradycardia and hypertension
What are the branches that occur along the length of an axon?
Collaterals are branches that sometimes occur along the length of an axon. Parasympathetic branch is the branch of the autonomic nervous system causes increased secretion by digestive glands.
How does the cell division in germ cell occur?
