What else can I help you with?
A neuron that is excited to subthreshold is said to be?
A neuron that is excited to subthreshold is said to be depolarized. This means that the neuron's membrane potential has become less negative, bringing it closer to the threshold potential needed to generate an action potential.
What proteins does a neuron make?
A molecule is many order of magnitude smaller than a neuron. A neuron is made of molecules not the other way around.
When does the activation of a motor neuron occur in a stretch flex?
The activation of a motor neuron in a stretch reflex occurs when a muscle spindle detects a quick stretch in a muscle. This sensory information is relayed to the spinal cord, where it synapses with the motor neuron corresponding to the stretched muscle. The motor neuron is then activated, causing the muscle to contract and counteract the stretch, leading to the reflexive response. This process happens rapidly, often without conscious thought, to protect the muscle from excessive stretching.
If a child is watching a favorite sibling getting scolded for misbehavior which type of neuron is likely to be activated in an empathetic response to this observation?
In short - there is no one type of neuron that would be activated; there would be many types across a number of regions such as those involved in appreciation (temporal association areas, occipital cortices, prefrontal areas) as well limbic areas involved in emotion (amygdala, orbifrontal cortex, raphe nuclei, locus coerules and the hippocampus). It's the Mirror Neuron
Where and how do autoreceptors work?
Autoreceptors are located on the presynaptic neuron and are activated by neurotransmitters released by that neuron. When neurotransmitter levels reach a certain threshold, autoreceptors inhibit further release of neurotransmitters, providing negative feedback regulation to control neurotransmission and maintain homeostasis in the nervous system.
Transmit neural messages from neuron to neuron?
Neurons send messages by way of chemical signalers called neurotransmitters. An activated neuron releases neurotransmitters and their collective action can stimulate another neuron. These individual firing sequences are called action potentials.
What is the message that travels through the neuron?
An Impulse
What is the insulating material found around a neuron?
myelin, although it is really only around the AXON of the neuron, not the whole neuron.
A neuron that is excited to subthreshold is said to be?
A neuron that is excited to subthreshold is said to be depolarized. This means that the neuron's membrane potential has become less negative, bringing it closer to the threshold potential needed to generate an action potential.
What is the voltage change at the receptor site of a neuron?
When a neuron is activated, there is a change in the voltage across the cell membrane at the receptor site. This change is known as a postsynaptic potential and can be either depolarizing (making the neuron more likely to fire an action potential) or hyperpolarizing (making the neuron less likely to fire an action potential).
What is a neuron that transmits a nerve impulse toward the central nervous system is called what?
A sensory neuron transmits a nerve impulse towards the central nervous system. These nerve cells activated by input, transmits sensory information.
What proteins does a neuron make?
A molecule is many order of magnitude smaller than a neuron. A neuron is made of molecules not the other way around.
What is the concentration of sodium in a neuron?
The concentration of sodium inside a neuron is lower than outside due to the activity of the sodium-potassium pump. Specifically, the concentration of sodium ions is higher outside the neuron at around 145mM, compared to around 10-15mM inside the neuron.
What do molecules make?
A molecule is many order of magnitude smaller than a neuron. A neuron is made of molecules not the other way around.

The sheath around some neuron fibers that aids in regeneration?
neurilemma
