What do impulses that move down the T tubules most directly cause?
Impulses that move down the T tubules most directly cause the release of calcium ions from the sarcoplasmic reticulum in muscle cells. This calcium release triggers muscle contraction by interacting with the contractile proteins within the muscle fibers.
What does fear do to your brain?
Fear triggers the release of stress hormones like adrenaline and cortisol in the brain, causing the body's fight-or-flight response. This can lead to increased heart rate, heightened senses, and decreased rational thinking. Chronic fear can also negatively impact brain function over time by contributing to anxiety and stress-related disorders.
Explain how sound waves stimulate the hair cells of the spiral organ of corti to cause hearing?
When the sound waves stimulate the hair cells of the spiral organ of corti to cause hearing, the impulses are usually sent to the brain.
Does the epilepsy have anything to do with nerve cell?
Yes, epilepsy is a neurological disorder that affects nerve cell activity in the brain, leading to recurrent seizures. Nerve cells, also known as neurons, play a key role in transmitting electrical signals in the brain, and disruptions in this process can trigger abnormal brain activity characteristic of epilepsy.
How does sunlight cause the brain to produce happy hormones?
Sunlight exposure triggers the brain to produce serotonin, a neurotransmitter that contributes to mood regulation. Serotonin levels typically increase with exposure to natural light, which can help improve mood and reduce symptoms of depression and anxiety.
What do electrical impulses of the brain cause?
Electrical impulses of the brain are the nervous impulses that the nervous system uses to control body functions. These impulses may be relayed within the brain, or may be carried to the peripheral nervous system.
How are brain impulses transmitted when seizure activity occurs?
During seizure activity, abnormal electrical impulses in the brain cause excessive, uncontrolled firing of neurons. This leads to a cascade of hyperexcitability spreading through the brain, resulting in seizures. The transmission of these electrical impulses can disrupt normal brain function and cause the characteristic symptoms of a seizure.
How does Ekwefi react?
An action happens. Her organs observe and send neural impulses to her brain. Her brain processes what happens, lighting up neural pathways. These chemicals and impulses cause her brain to make decisions.
Abnormal electrical impulses in the neurons of the brain cause?
Abnormal electrical impulses in the neurons of the brain can cause seizures, which are sudden, uncontrolled electrical disturbances in the brain. These abnormal impulses can also lead to conditions such as epilepsy, where a person experiences recurrent seizures. Identifying and managing these abnormal electrical activities is crucial in treating such conditions.
What is the Primary etiology of seizure?
Primary etiology of seizure is any form of brain injury. When the electrical impulses escape their limit in the brain, this will cause seizure.
What is the difference between sensory nerve and motor nerves?
Sensory nerves carry impulses to the brain (as sights seen, sounds heard, etc.). Motor nerves carry impulses from the brain to cause the body to do things such as move muscles.
What are the neurons that carry impulses from the brain or spinal cord to other organs and cause muscles to contract?
motor neurons
Is a reflex is a voluntary action?
No, it is by definition involuntary. The neural impulses which cause the action do not go through the brain at all.
Why Eating food processed from a microwave oven causes permanent brain damage by shorting out electrical impulses in the brain?
Not true. Eating food processed from a microwave oven does not cause brain damage.
What are the hormones that puberty cause iluk7i7yukgfkryfkukfuj76ijhffn7ur67urtut67?
The brain sends signal to the adrenal glands to produce hormones. Also testis produce a lot of testosterone and in females its oestrogen
The process by which neural impulses are transmitted through the nervous system is best described as?
The process by which neural impulses are transmitted through the nervous system is best described as electric impulses. Any damage to a nerve in the system will cause a breakdown in communication between nerve ending and the brain.
How does your brain send messages to move?
Your brain sends electrical impulses to your muscles that cause them to contract and relax causing your limbs to bend and straighten. And it does it 10 times faster than you can blink.
