What are chemicals that retard behavior by either speeding up or slowing down nerve impulses?
Chemicals that retard behavior by affecting nerve impulses can include depressants like alcohol, benzodiazepines, and barbiturates, which slow down nerve impulses. Stimulants like amphetamines and cocaine can speed up nerve impulses. These substances can alter brain function and behavior by modulating neurotransmitters in the brain.
What chemicals are used to transmit impulses through the neurons?
the transmission of a nerve impulse along a neuron from one end to the other occurs as a result of chemical changes across the membrane of the neuron. The membrane of an unstimulated neuron is polarized that is there is a difference in electrical.
Which organs cannot live without oxygen?
All organs in the body require oxygen to function, but the brain is particularly sensitive to even short periods without oxygen. Without oxygen, brain cells begin to die within minutes, leading to permanent damage or death. Other organs such as the heart, kidneys, and liver also depend on oxygen for proper function.
Why is it important that your brain responds to of carbon dioxide in your blood?
It is important for the brain to respond to changes in carbon dioxide levels as high levels can indicate a decrease in oxygen supply to the body. This triggers the brain to increase breathing rate to expel excess carbon dioxide and bring more oxygen into the body, helping to maintain proper functioning of vital organs.
How low can infant oxygen level go before brain damage occurs?
Brain damage can occur if an infant's oxygen level drops below 85-90%. Prolonged periods of low oxygen levels can lead to hypoxia, causing damage to the brain and other vital organs. It is important to monitor infants closely and seek immediate medical attention if there are any concerns about oxygen levels.
What Impulses from the sense organs travels to the brain along?
association neurons
Impulses are sent from the brain to the effector organs along what neurones?
Impulses are sent from the brain to the effector organs along motor neurons. These motor neurons are part of the peripheral nervous system and carry signals from the central nervous system to muscles and glands, allowing for coordinated movement and responses.
Witch organ transmit information to the brain?
The nervous system, specifically the sensory organs such as the eyes, ears, skin, nose, and tongue, transmit information to the brain. Signals, in the form of electrical impulses, travel along nerves to deliver sensory information to the brain for processing.
What sends impulses to brain?
sensory neurons
Do Nerve impulses travel quickly?
yes, in woman nerve impulses travel to the brain faster than men
What form sensory impulses?
Sensory impulses are typically in the form of electrical signals that travel along nerve fibers from sensory receptors to the brain or spinal cord. These impulses carry information about sensations such as touch, temperature, pain, and pressure. The brain then processes these impulses to generate a conscious perception of the sensory input.
What is the brain's relationship with other organs in your body?
all of your organs are connected to your brain. for example when you touch something hot your brain sends impulses to the body part to move.
Which type of neurons impulses from sense organs to the spinal or brain?
Sensory neurons
What carries impulses through the spinal cord and brain to other organs?
Afferent nerves
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.
What cells carry impulses from sense organs to the brain and spinal cord?
Neurons (nerve cells)
Where do nerve impulses travel?
Nerve impulses travel up through nerves, into the spinal cord and into one of the different lobes of the brain depending on where the impulse comes from. For example, if the impulse comes from your ear, the impulse would travel to the temporal lobe.
