The primary neurotransmitter used by the neurons in the basal nuclei is gamma-aminobutyric acid (GABA), which is an inhibitory neurotransmitter. GABA plays a crucial role in modulating motor control and reducing excessive neuronal activity within the basal ganglia circuits. Additionally, other neurotransmitters such as dopamine and glutamate are also involved in the functioning of the basal nuclei, contributing to their regulatory roles in movement and behavior.

What is the criteria used to functionally classify neurons?
Neurons are functionally classified based on their structure, neurotransmitter type, and the direction of signal transmission. Structural classifications include multipolar, bipolar, and unipolar neurons, while neurotransmitter types can be excitatory or inhibitory. Direction of signal transmission can be sensory (afferent), motor (efferent), or interneurons.
Does parasympathetic have postganglionic axons secrete norepinephrine?
No, parasympathetic postganglionic axons secrete the neurotransmitter acetylcholine, not norepinephrine. Norepinephrine is the primary neurotransmitter used by postganglionic neurons of the sympathetic nervous system.
What neurotransmitter is used by most postganglionic sympathetic neurons?
At the effector end (nerve to effector organ junction) the transmitter is Nor Adrenaline. However, at the nerve-nerve junctions (ganglions) the transmitter is Acetyl Choline.
What is the name for the impulse generated when a neuron fires?
Brain send the message via nerve impulses involving neurons which use the neuro-transmitter AcetylcholineAcetylcholine- a neurotransmitter released at the neuromuscular junction triggers a muscle action potential, which leads to muscle contraction
What is the term used to describe cells that have nuclei?
Cells that have nuclei are eukaryotic.

How do neurotransmitters differ from neuromodulators?
is a substance that is produced by a neuron that is other than a neurotransmitter and is used to transmit information to other neurons to regulate their activities. examples are dopamine, s.erotonin or histamine
What neurotransmitter is used by most postganglionic sympathetic neurons?
At the effector end (nerve to effector organ junction) the transmitter is Nor Adrenaline. However, at the nerve-nerve junctions (ganglions) the transmitter is Acetyl Choline.
What is gamma aminoburyric acid?
Gamma aminobutyric acid (GABA) is a neurotransmitter in the brain that helps to reduce the activity of neurons, leading to a calming or inhibitory effect. It plays a key role in regulating mood, anxiety, and stress levels. GABA is also available in supplement form and is sometimes used to promote relaxation and improve sleep.
What is the name for the impulse generated when a neuron fires?
Brain send the message via nerve impulses involving neurons which use the neuro-transmitter AcetylcholineAcetylcholine- a neurotransmitter released at the neuromuscular junction triggers a muscle action potential, which leads to muscle contraction
What is the neurotransmitter used to cause contractions in muscles?
Acetylcholine
What is the term used to describe cells that have nuclei?
Cells that have nuclei are eukaryotic.
What is the name of enzyme which is used for inactivation of neurotransmitter?
There are a number of neurotransmitter deactivators. For example acetylcholinesterase and anticholinesterases. These are 2 of the most important ones.
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.
What is the neurotransmitter used at the neuro muscular junction is?
The neurotransmitter used at the neuromuscular junction is acetylcholine. It is released from the motor neuron terminals and binds to receptors on the muscle cell membrane, leading to muscle contraction.
What does BMT mean when trying to get pregnant?
It's used when you take the temperature to find out when you are ovulating and means Basal Metabolic Temperature aka Basal Body Temperature (BBT).
