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.
The effect that a neurotransmitter has on the postsynaptic membrane depends on?
the specific type of neurotransmitter, its binding to receptors on the postsynaptic membrane, and the resulting activation or inhibition of postsynaptic neurons. This interaction can lead to changes in membrane potential, triggering action potentials and influencing communication between neurons.
In addition to the nucleus cytoplasm and cell membrane a single neuron possesses what?
A single neuron also possesses dendrites, which receive signals from other neurons, and an axon, which transmits signals to other neurons or cells. Additionally, neurons have synaptic connections that allow them to communicate with other neurons or cells through neurotransmitters.
Voltage regulated channels can be found where?
Voltage-regulated channels can be found in excitable cells, such as neurons and muscle cells, where they help regulate the flow of ions across the cell membrane in response to changes in membrane potential. These channels play a crucial role in processes like action potentials in neurons and muscle contraction.
What is the small change in the charge across a neuron's membrane called?
The small change in the charge across a neuron's membrane is known as the action potential. It is a brief electrical impulse that travels along the neuron's membrane, allowing for the transmission of signals between neurons.
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 accounts for the resting membrane potential seen in unstimulated nerve and muscle cells?
Sodium-potassium pump
What is relative permeability of potassium ions in unstimulated cells?
The relative permeability of potassium ions in unstimulated cells is generally high, as potassium ions play a key role in maintaining the cell's resting membrane potential. This allows for potassium ions to move across the cell membrane more easily than other ions.
Is unstimulated a word?
Yes.
What cell has slender extentions of the plasma membrane?
Neurons
Is the membrane of neurons very permeable to Na when at rest?
the same as that to potassium
Neurons which are wrapped in a fatty membrane are?
Neurons wrapped in a fatty membrane are called myelinated neurons. The fatty substance that wraps around the neuron is called myelin, and it helps to insulate and speed up the transmission of electrical impulses along the neuron's axon. Myelinated neurons are found in the central and peripheral nervous system.
The effect that a neurotransmitter has on the postsynaptic membrane depends on?
the specific type of neurotransmitter, its binding to receptors on the postsynaptic membrane, and the resulting activation or inhibition of postsynaptic neurons. This interaction can lead to changes in membrane potential, triggering action potentials and influencing communication between neurons.
The resting membrane potential in neurons ranges from?
-60mV to -70mV
What transmission of the depolarization wave along the neurons membrane?
Action potential
The junction between a motor neurons axon and the muscle cell membrane is called?
neuromuscular junction or myoneural junction
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.
