What are 2 examples when a cell might use exocytosis?
A cell might use exocytosis to release neurotransmitters from a neuron to communicate with other cells in the nervous system. Another example is when a cell secretes hormones from an endocrine gland into the bloodstream for distribution throughout the body.
For what reasons might a cell use mitosis?
To Heal Injuries by reproducing itself (Cell division).
What causes a cholinergic crisis?
The most common cause of the cholinergic crisis is from medication or accidental exposure to insecticides such as Malathion or herbicides.Other sources include nerve gas such as sarin gas and VX gas. Use of these weapons is against the rules of warfare set by the Geneva Convention established in 1925. Recently they have been used as weapons of terrorism.A cholinergic crisis describes the condition of excess acetylcholine at neuromuscular junctions and the synaptic gap in the central and peripheral nervous system.Acetylcholine acts as a neurotransmitter for muscle fibers, in the peripheral nervous system, and extensively in the brain. The enzyme acetylcholinesterase rapidly breaks down the neurotransmitter once it is released.Not enough acetylcholinesterase leads to a buildup of acetylcholine and an increase in the level and duration of neurotransmitter signal. Symptoms of the cholinergic crisis include excess salivation (drooling), lacrimation (many tears), emesis (vomiting), and diarrhea.Striated and smooth muscles eventually stop responding due to the accumulation of acetylcholine. The result is paralysis and respiratory failure.
How does alcohol affect the nervous system?
Alcohol affects the nervous system by slowing down communication between brain cells, leading to impaired coordination, judgment, and decision-making. It can also disrupt neurotransmitter levels, affecting mood and behavior. Long-term alcohol use can damage nerve cells and contribute to conditions like memory loss and cognitive impairment.
What symbols do scientists use represent dominant and recessive genes?
Scientists use uppercase letters to represent dominant genes and lowercase letters to represent recessive genes. For example, "R" might represent a dominant gene for round seeds, while "r" might represent a recessive gene for wrinkled seeds.
What neurotransmitter might parietal lobe use?
The parietal lobe primarily utilizes several neurotransmitters, with glutamate being the most prominent excitatory neurotransmitter involved in processing sensory information. Additionally, gamma-aminobutyric acid (GABA) serves as the main inhibitory neurotransmitter in this region, helping to regulate neural activity. Other neurotransmitters, such as acetylcholine and serotonin, may also play roles in modulating functions related to attention and sensory integration.
What part of the brain are most sensory areas located?
The hands, lips, tongue and genitals have the largest sensory representations. The hands, lips and mouth area also have the largest motor area representation. For more information on this, use the keywords "sensory and motor homunculi"
What do you use more your temporal lobe or your occipital lobe?
You use your temporal lobe more for functions like processing auditory information, language comprehension, and memory. Your occipital lobe is primarily responsible for processing visual information and is used more for tasks like recognizing shapes, colors, and objects.
How might psychologists use drugs that mimic the effects of neurotransmitters to treat psychological disorders?
psychologists use drugs like high drugs which alerts our minds in unconscious behavior and these mimic the effect of neurotransmitter in our body
What part of the brain use smell?
Frontal Lobe
Which part of the brain perceives the sense of sight?
The thalamus, occipital lobe, parietal lobe, and temporal lobe all play parts in visual perception. Most of the processing of visual information occurs in the occipital lobes. If you want to find out if you are left occipital lobe oriented or right occipital lobe orientated, you can try this simple experiment. With both eyes open, look at a small spot on a wall or ceiling across the room from you. Then use one hand and touch the thumb and index fingers together and hold it about arm's length away in front of you and then place the circle you made with your fingers over the spot and alternate closing one eye at a time. You will notice that you can only see the spot with one eye open. It will be the left or the right eye. This shows your dominant vision tendency and whether you prefer to use your left or right eye more.
How do you use commission in a sentence?
the plane was out of commission
Is the frontal lobe of the brain used when driving a motor vehicle?
yes of course, our frontal lobe helps us in thinking, and while driving we obviously think....don't we...so we use our frontal lobe.. while driving.
What part of the brain do you use when doing math?
The left lobe of your brain is the part of the brain you use to do math.
Which is better to get your ears pierced at Claire's or La Lobe?
use Claire's (from experience)
What part of the brain helps to decide what words to use in your speech?
the frontal lobe
What is the cpt code for upper lobe lobectomy?
The CPT code for an upper lobe lobectomy is 32480. This code specifically refers to the surgical removal of a lobe of the lung, including the upper lobe. It is important to use the correct code based on the specifics of the procedure performed, so always verify with the latest coding guidelines or consult with a coding specialist if needed.
