What else can I help you with?
How is a resting potential achieved in the nervous system?
The resting nerve cell is not being stimulated to send a nerve impulse
What is a resting motor neuron expected to do?
exhibit a resting potential that is more negative than the "threshold" potential
What is the difference between the pH of the resting saliva and the stimulated saliva?
The pH of resting saliva is typically around 6.5 to 7.0, while the pH of stimulated saliva is slightly higher, around 7.0 to 7.5. Stimulated saliva is produced in response to stimuli like taste, smell, or chewing, and has a higher buffering capacity to help neutralize acids more effectively.
Which of these is stimulated by parasympathetic nerves?
Parasympathetic nerves stimulate resting and digesting. Therefore, stomach activity is stimulated by parasympathetic nerves.
If a resting neuron is stimulated and there is an inward flow of positive charges into the cell the membrane potential will?
If a resting neuron is stimulated and there is an inward flow of positive charges into the cell, the membrane potential will depolarize, meaning the inside of the cell becomes less negative. This can trigger an action potential if the depolarization reaches the threshold level.
When a section of the resting neuron is stimulated?
When a section of a resting neuron is stimulated, it causes a localized change in membrane potential, typically depolarization. This change occurs because sodium channels open, allowing Na+ ions to flow into the neuron. If the depolarization reaches a certain threshold, it can trigger an action potential, leading to the propagation of the signal along the axon. This process is crucial for neural communication and the transmission of information throughout the nervous system.
When does muscle relaxation occur?
Muscle relaxation occurs when the muscle fibers stop contracting and return to their resting state after being stimulated.
Is the resting potential of a neuron approximately -70 microvolts?
Yes, the resting potential of a neuron is typically around -70 millivolts (mV), not microvolts. The resting potential is the membrane potential of a neuron when it is not being stimulated to send a signal.
How much does a muscle contract?
It's maximum contraction is about one third of its resting length.
What is an unstimulated neuron?
An unstimulated neuron is a nerve cell that is not currently transmitting signals. It is in a resting state, with a stable membrane potential, and is not actively firing action potentials or sending messages to other neurons.
What is occurring when a muscle cell cannot be stimulated during the absolute refractory period?
During the absolute refractory period, a muscle cell cannot be stimulated because it is in a state where it is unable to respond to any stimuli, no matter how strong. This period is caused by the inactivation of voltage-gated sodium channels and the inability to generate another action potential until these channels have returned to their resting state.
What happens to your heart when you are resting?
when your resting your heart beats slowly because your relaxing
