If a mutation occurs in a somatic cell how is it transmitted?
Mutations occurring in somatic cells are not transmitted to offspring because they only affect the individual in which they occur. These mutations are not present in the germline cells (sperm or egg cells) and therefore cannot be passed on to future generations.
What is Todd's paralysis?
Todd's paralysis, also known as postictal paralysis, is a temporary weakness or paralysis that occurs after a seizure. It can affect one side of the body or multiple limbs, typically lasting anywhere from a few minutes to a few hours. This phenomenon is more commonly seen in focal or partial seizures and usually resolves on its own without long-term complications.
What metabolic activity in plants produces sugars?
Photosynthesis is the metabolic activity in plants that produces sugars. During photosynthesis, plants use sunlight to convert carbon dioxide and water into glucose and oxygen. This process occurs in the chloroplasts of plant cells.
How does allosteric inhibition differ from competitive inhibition in terms of their mechanisms of action on enzymes?
Allosteric inhibition and competitive inhibition are two ways enzymes can be regulated. Allosteric inhibition occurs when a molecule binds to a site on the enzyme that is not the active site, causing a change in the enzyme's shape and reducing its activity. Competitive inhibition, on the other hand, occurs when a molecule binds to the active site of the enzyme, blocking the substrate from binding and inhibiting the enzyme's activity. In summary, allosteric inhibition affects enzyme activity by binding to a site other than the active site, while competitive inhibition affects enzyme activity by binding to the active site directly.
What is a disease that occurs continuously in a particular region but has low mortality?
Dengue fever is a disease that occurs continuously in specific regions but typically has low mortality rates. It is transmitted by mosquitoes and symptoms include high fever, severe headache, joint and muscle pain, and rash. While most cases result in full recovery, severe cases can be life-threatening.
What is seizure from bang to head?
A seizure from a bang to the head typically refers to a seizure that occurs as a result of a traumatic brain injury, such as a concussion. The trauma can disrupt normal brain activity, leading to abnormal electrical discharges that manifest as a seizure. This type of seizure can occur immediately after the injury or may develop weeks or months later. It is important to seek medical attention if a seizure occurs following head trauma to assess potential underlying damage.
Can a man give a woman gardnerella?
Gardnerella, or bacterial vaginosis, is not a sexually transmitted infection. It occurs due to an imbalance of vaginal bacteria. While sexual activity can sometimes contribute to this imbalance, it is not directly transmitted from a man to a woman.
What light is converted into nerve impulses?
Light is converted into nerve impulses through the process of phototransduction, which occurs in the photoreceptor cells of the retina (rods and cones). When light photons strike these cells, they trigger a chemical change in photopigments, leading to a series of biochemical reactions that ultimately generate an electrical signal. This signal is then transmitted as nerve impulses via the optic nerve to the brain, where it is processed into visual images.
Can you fall into a coma after having a seizure from not taking your Ativan?
Yes, it is possible to fall into a coma after having a seizure, especially if the seizure is severe or prolonged. Not taking Ativan, which is used to manage seizures and anxiety, may increase the risk of seizure activity. However, whether a coma occurs can depend on various factors, including the individual's overall health, the duration of the seizure, and any underlying conditions. It's crucial to seek medical attention if seizures occur, particularly if medication has been missed.
Why would a person having a seizure develop hypothermia?
A person having a seizure may develop hypothermia due to several factors, including prolonged muscle activity and increased metabolic demand during the seizure, which can lead to heat loss if the individual is not in a warm environment. Additionally, seizures can impair the body's ability to regulate temperature, particularly if there is a postictal state (the period following the seizure) where the person may be less responsive. If the seizure occurs in a cold environment or the individual is unable to generate adequate body heat, this can further contribute to the risk of hypothermia.
What can cause a seizure?
Some things may trigger a seizure, but on the other hand, seizures may be a natural "mal-function" of the brain. Pictures on a TV screen can trigger a seizure or being overwhelmed can trigger a seizure. It is known that some people can reduce or completely stop their seizures with meditation and removing the negative things in your everyday life.
Order of how sensory impulses reach the brain starting at the retina all the way to the occipital lobe?
Sensory impulses from the retina begin their journey when light is converted into electrical signals by photoreceptor cells (rods and cones). These signals are then transmitted through the retinal ganglion cells, forming the optic nerve. The optic nerve carries the impulses to the lateral geniculate nucleus (LGN) of the thalamus, where they are processed and relayed. Finally, the signals travel to the occipital lobe of the brain, where visual perception occurs.
Why seizure often occurs during sleep time?
Seizures often occur during sleep due to changes in brain activity and the balance of neurotransmitters, which can be disrupted during this state. The brain's decreased responsiveness to external stimuli during sleep may also contribute to an increased likelihood of seizure activity. Additionally, certain types of epilepsy, such as nocturnal seizures, are specifically linked to sleep cycles, particularly during rapid eye movement (REM) sleep when brain activity is heightened. Lack of sleep or sleep disorders can further exacerbate the risk of seizures.
Is it possible for someone to die from a petit mal seizure?
It is very rare for someone to die directly from a petit mal seizure. Petit mal seizures are typically brief and do not result in physical harm or complications that could lead to death. However, if a petit mal seizure occurs in a dangerous situation, such as while swimming or driving, there is a risk of harm or death from accidents related to the seizure.

Why did my son's eyes roll back in his head 6 times for 1second each time playing with a flashing light toy with a song?
Some partial seizures are associated with an altered level of consciousness, even though the person might appear to be awake and his or her eyes may be open. In this type of seizure, called a complex partial seizure, the affected person is unaware of the people nearby during the event, is not aware of his or her own movements or behaviors during the seizure, and does not remember the seizure after it occurs. When the person having a partial seizure is aware of having a seizure, is aware of his or her surroundings and remembers the event afterward, the seizure is classified as a simple partial seizure.
