What is the smallest functional unit of the nervous system?
The neuron is the smallest functional unit of the nervous system. It is responsible for transmitting information through electrical and chemical signals. Neurons make up the basic building blocks of the nervous system and are essential for communication within the brain and between the brain and the rest of the body.
How the brain play a part in nervous system?
The brain is the central hub of the nervous system, responsible for processing and interpreting sensory information, making decisions, and sending out commands to the rest of the body through the spinal cord. It controls various functions such as movement, thinking, and emotions by sending and receiving electrical signals between neurons. Overall, the brain plays a crucial role in coordinating all activities of the nervous system.
Do students do better in school when they have more sleep than the people who have less sleep?
Yes, studies have shown that students who get more sleep tend to perform better in school compared to those who get less sleep. Adequate sleep is important for cognitive function, memory retention, and overall academic performance. A consistent sleep schedule that allows for enough rest can positively impact learning abilities and concentration levels.
Why did sigmound freud leave his country?
Sigmund Freud left Vienna in 1938 to escape Nazi persecution as he was Jewish. He settled in London, where he spent the rest of his life and continued his work in psychoanalysis.
Explanation for being absent in school?
I was feeling unwell and needed to rest at home to recover. I will provide any necessary documentation from my healthcare provider upon returning to school. Thank you for your understanding.
It is the membrane potential of a neuron at rest?
Yes,the membrane potential of a neuron is at rest because it is the difference in electrical charge between inside and outside a resting neuron.
What is a nerve membrane at rest called?
When the neural membrane (neurolemma) is at rest it is said to have resting potential, polarized, and has a negative charge inside.
Does static electricity electrical charges that are not in motion?
Yes, static electricity is the study of charge in rest
Why Sodium and potassium ion can only cross in axon membrane through protein channel explain why?
At rest sodium in the outside and potassium on the inside as action potential propagate along the axon, depolirization happens and sodium channel opens and allow sodium ions to flood into the neurone. A wave of deporization spread along the neuron, the neuron membrane contain specialised protein called channels. the channel from pore.
What is a charge in motion?
A charge in motion is usually called an electric current, but could also be called dynamic electricity (analogous to a charge at rest being called static electricity).
How electrical signal exist related with membrane potential and and action potential?
Resting potential and action potential are both names for the measure of electrical voltage within the membrane of a cell. Specifically, these terms are used in describing the transfer of information along neural pathways. Resting potential is a state where cells are at rest. However, if an electrical response or depolarization reaches threshold, then ion channels open, allowing sodium ions to rush into the membrane and increase the voltage measure, firing an action potential along the length of this membrane.
Explain how a neuron enter a state of depolarization?
At rest, a neuron is highly polarized -- a significant electrical charge difference exists between the inside and the outside (poles) of the cell. This polarity is what allows the cell to quickly respond to triggering events and do work, similar to the charge in a battery. A neuron de-polarizes when something reduces that charge difference, typically when pores in the cell membrane are unblocked, allowing charged ions to flow. Technically, a reduction of even a single electron of polar charge is a "depolarization". This can occur by dozens of mechanisms. However, the usual process is: (1) a neuron is polarized, (2) an electrical signal traveling inside the neuron changes the internal membrane charge just enough to cause voltage-sensitive pores to open, which (3) allows a massive influx of charged ions from outside the cell. This now depolarized cell recovers its resting polarity quickly through a reverse flow of electrons and via ion pumps in the membrane.
What are electric charge?
the static electric charges refer to the charges which are at rest, in other words stationary positions.
Functions of the nuclear membrane?
Membrane or barrier that separates the nucleus from the rest of the cell.
Is static electricity a charge?
Static charge mean "Charges at rest". And at rest, any charge can have its electric field, but its meg.field is always zero at rest.
Membrane that separates the nucleus from the rest of the cell?
The anwser is nuclear membrane! Is that not self explanitory?
What membrane covers the rest of a bone?
The periosteum.
