What else can I help you with?
What bridge the gap between a neuron sending a message and the neuron receiving it?
neurotransmitters
What is the junction where the axon terminal of a sending neuron communicates with a receiving neuron?
The junction where the axon terminal of a sending neuron communicates with a receiving neuron is called a synapse. Neurotransmitters are released from the axon terminal into the synaptic cleft, where they bind to receptors on the receiving neuron, allowing for the transmission of signals between neurons.
What is the space between the sending and the receiving neuron called?
The space between the sending neuron's axon terminal and the receiving neuron's dendrite is called the synaptic cleft. Neurotransmitters are released into this space to transmit signals between neurons.
What name is given to a neuron that is not sending a nervous impulse?
A neuron that is not sending a nervous impulse is typically referred to as a resting neuron. In its resting state, the neuron is polarized with a negative internal charge.
When a neuron's resting potential is occurring the neuron is what charge on the inside?
resting potiental
What is the tiny electrical charge that exists when a neuron is neither receiving nor sending information?
a resting potential
What neuron is before a synapse?
The synapse consists of the two neurons, one of which is sending information to the other. The sending neuron is known as the pre-synaptic neuron (i.e. before the synapse) while the receiving neuron is known as the post-synaptic neuron (i.e. after the synapse).
Which condition is a neuron in when the outside of the neuron has a net positive charge and the inside has a negative charge?
resting potiental
What causes the inside of a neuron to be negative?
The inside of a neuron is negative due to a higher concentration of negatively charged ions, particularly chloride and proteins, compared to the outside of the neuron. This difference in ion concentration creates a resting membrane potential, which is maintained by the sodium-potassium pump and ion channels in the neuron's cell membrane.
What is the spce between two neurons where the axon of a sending neuron communicates with the dendrites of a receiving neuron by using chemical messages called?
The space between two neurons where communication occurs using chemical messages is called the synaptic cleft. Neurotransmitters are released from the axon terminal of the sending neuron and bind to receptors on the dendrites of the receiving neuron, facilitating the transmission of signals between the two.
A polarized neuron has fewer positive ions inside in comparison to the outside of the neuron?
A polarized neuron has a more negative charge inside compared to the outside due to the presence of more negatively charged ions inside the neuron. This difference in charge is maintained by the activity of ion pumps and channels in the neuron's cell membrane.
What is synaptic delay?
Synaptic delay is the period of time for neurotransmitter chemicals released from the axon terminus of the sending neuron to cross the synaptic gap by diffusion and attach to matching receptors on the receiving neuron, initiating a reaction (either stimulatory or inhibitory) in that neuron.
