What else can I help you with?
What are the functional region of a neuron?
receptive conducting secretory
What is the junction where the axon terminal of a sending neuron communicates?
The question isn't clear enough. Does it mean the part that sends info. through the neuron (the axon)? Or does it mean the part that sends information to other neurons (the synapse)?
Where is the Tigger zone on a unipolar neuron?
The "Tigger zone" in a unipolar neuron is the initial segment of the axon where action potentials are generated. Here, graded potentials from the dendrites accumulate and if they reach a certain threshold, an action potential is triggered.
The input zone of a neuron is the?
­The dendrites and cell body. Incoming signals from other neurons are received here.
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 are the functional region of a neuron?
receptive conducting secretory
What portion of a neuron should be called its secretory component?
Axon/Axon terminals
What is the input zone of a motor neuron?
dendrites
What is a Secretory synapse?
A secretory synapse is a type of synapse where the presynaptic neuron releases neurotransmitters into the extracellular space rather than across a synaptic cleft to act on a postsynaptic neuron. This communication occurs through volume transmission, allowing for more widespread and diffuse signaling compared to conventional synaptic transmission. Examples include neurosecretory cells in the hypothalamus that release hormones into the bloodstream.

What is the transmission zone of a neuron?
I have never heard of the term 'transmission zone' (which may be someone's personal name for what I'm about to explain) but neurons send their chemical signals across what is known as a synapse, the region where the axon of one neuron meets up with another neuron (most often a dendrite). The space between these two neurons (the non-neuron space in the synapse) is called the synaptic cleft. Through this space, neurotransmitters pass through and act on the receiving neuron once they reach it.

­The dendrites and cell body. Incoming signals from other neurons are received here.

What is the function of the secretory system?
The secretory system does not really exist. There is a secretory mechanism that is part of the endocrine system, and that secretes hormones into the blood stream.
What is the trigger point at which a neuron will fire called?
Its where there are a lot of sodium channels. Once the trigger zone is 'triggered' to threshold (from -70mV to -55mv), then an action potential occurs. trigger zone in MOTOR neurons are in the axon hillock and in SENSORY neurons, they're in the 1st unmyelinated area (first node of ranvier).
The trigger zone of a neuron includes?
The trigger zone of a neuron includes the axon hillock, where graded potentials are summed together to determine if an action potential will be initiated. It is the region where voltage-gated sodium channels are concentrated and play a crucial role in generating an action potential. If the depolarization at the trigger zone reaches a certain threshold, an action potential will be generated and propagated down the axon.
