What is the secretory zone of neuron?
The secretory zone of a neuron refers to the region where neurotransmitters are synthesized, stored, and released. It includes the synaptic vesicles that contain the neurotransmitters and the presynaptic terminal where they are released into the synaptic cleft. This zone plays a crucial role in transmitting signals between neurons and facilitating communication in the nervous system.
Disturbances when will sensory neurons result in an action potential?
Disturbances to sensory neurons can cause depolarization of the neuron's membrane, reaching a threshold that triggers an action potential. This action potential then travels along the neuron's axon to the central nervous system, where it is processed and interpreted as a sensory experience.
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.
How does the plasma membrane at the trigger zone differ from that on the soma?
The plasma membrane at the trigger zone of a neuron typically contains a higher density of voltage-gated ion channels, which are responsible for initiating action potentials. This allows for rapid signal transmission along the axon. In contrast, the plasma membrane on the soma (cell body) is involved in integrating signals from various sources before they are transmitted down the axon.
The input zone of a neuron is the?
­The dendrites and cell body. Incoming signals from other neurons are received here.
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).
A neuron reaches its trigger point when?
A neuron reaches its trigger point when the combined inputs it receives from other neurons or sensory receptors exceed a certain threshold. Once this threshold is reached, the neuron generates an action potential, which propagates down its axon to communicate with other neurons or muscle cells.
What is the input zone of a motor neuron?
dendrites

This zone plays a crucial role in transmitting signals between neurons and facilitating communication in the nervous system.
Would increasing frequency of stimulation to trigger zone change number of action potentials?
Yes, increasing the frequency of stimulation can increase the number of action potentials generated in the neuron. This is known as frequency-dependent facilitation, where rapid succession of stimuli can enhance the excitability of the neuron and lead to more action potentials being fired.
Disturbances when will sensory neurons result in an action potential?

Neurotransmitters find their way to and subsequently trigger firing of that neuron?
Excitatory neurotransmitter
Type of junction where a motor neuron and a skeleton muscle cell have contact?
Neuromuscular junction. It is the point of contact between the motor neuron and the skeletal muscle cell, where the motor neuron releases neurotransmitters that trigger muscle contraction.

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 input zone of a neuron is the?
­The dendrites and cell body. Incoming signals from other neurons are received here.
