What else can I help you with?
What part of the peripheral nervous tissue electrically insulates the neuron?
neurglia
How is the electrical charge inside the neuron?
Neurons send messages electrochemically and all chemicals in the body are electrically-charged. When neurons inside the body are electrically-charged, they are called ions. When a neuron is at rest, or not electrically-charged, the inside is negative and the outside is positive.
Do axon and dendrite touch?
No they do not. Information (neurotransmitters) is electrically fired over to the next neuron.
Is relay an active or passive device?
Yes, it is an electrically operated switch.
How are the sodium ions moved out of the neuron?
by "sodium pump", a process involving active transport
What is a active zone?
An active zone is a specialized region within a neuron where neurotransmitters are released to communicate with other neurons at a synapse. It is where the presynaptic neuron releases neurotransmitters into the synaptic cleft, which then bind to receptors on the postsynaptic neuron to facilitate communication between the two cells.
What is the basic function of a neuron?
Neurons are the basic building blocks of the nervous system and transmit signals between different parts of the body. They receive information from sensory organs, process it, and send out signals to muscles, glands, or other neurons. This allows for communication and coordination within the body.
To maintain its resting potential a neuron uses an what?
To maintain its resting potential, a neuron uses an active transport mechanism known as the sodium-potassium pump (Na+/K+ pump). This pump actively transports sodium ions (Na+) out of the neuron and potassium ions (K+) into the neuron, typically in a ratio of three sodium ions out for every two potassium ions in. This movement helps establish and maintain the negative charge inside the neuron relative to the outside environment, which is essential for the neuron's ability to transmit signals.
What the advantages of active and passive device?
An active device is any type of circuit component with the ability to electrically control electron flow (electricity controlling electricity). In order for a circuit to be properly called electronic, it must contain at least one active device
How do three neurons work together?
she sneezed with the thundering force of a hurricane!
Where is the neuron?
The Inter-neuron (also known as the local circuit neuron, relay neuron or the association neuron) is the neuron which connects the afferent and the efferent neurons in the neural pathways.
How do ions get across the neuron membrane?
Ions can cross the neuron membrane through specific protein channels. These channels are selective, allowing only certain ions to pass through based on their size and charge. Additionally, ions can also be transported across the neuron membrane through active transport processes, which require energy in the form of ATP.
