When gas reaches its condensation point it becomes what?
When a gas reaches its condensation point, it becomes a liquid. This is the point at which the gas molecules lose enough energy to come together and form a liquid phase.
When a gas reaches its condensation point it becomes?
When a gas reaches its condensation point, it becomes a liquid. This transition happens when the temperature of the gas is lowered to the point at which its particles lose enough kinetic energy to come together and form a liquid.
What is the specific temperature at which alumina reaches its melting point?
Alumina, also known as aluminum oxide, reaches its melting point at a specific temperature of 2,072 degrees Celsius (3,762 degrees Fahrenheit).
What is the presynaptic neuron release neurotransmitters in response to an influx of sodium ions?
When an action potential reaches the presynaptic neuron, voltage-gated sodium channels open, allowing sodium ions to enter the cell. This influx of sodium triggers the release of neurotransmitters stored in synaptic vesicles into the synaptic cleft. The neurotransmitters then bind to receptors on the postsynaptic neuron, allowing for communication between the two neurons.
What is the temperature of a substance when it turns into another state of matter?
The temperature at which a substance changes state is called its melting point or boiling point, depending on the transition. For example, when a solid turns into a liquid, it reaches its melting point; when a liquid turns into a gas, it reaches its boiling point.
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).
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.
A neuron fires only when its membrane reaches what?
A neuron fires when its membrane reaches a certain threshold potential. This threshold potential is typically around -55 to -65 millivolts. When the membrane potential reaches this level, an action potential is triggered and the neuron fires.
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.
When a sensory neuron is excited by some form of energy the resulting graded potential is called?
The resulting graded potential is called a generator potential when a sensory neuron is excited by some form of energy. This potential may trigger an action potential if it reaches threshold.
When an impulse reaches the end of a neuron it tiggers the releases of?
Neurotransmitters
When an action potential reaches the end of a neuron it triggers the release of?
neurotransmitters from the synaptic vesicles into the synapse. These neurotransmitters then bind to receptor proteins on the adjacent neuron, initiating a new action potential in the postsynaptic neuron.
When a neuron reaches its threshold?
When a neuron reaches its threshold, it initiates an action potential. This is a brief electrical impulse that allows for communication between neurons. The action potential travels down the axon of the neuron to transmit signals to other neurons or cells.
What happens when an impulse reaches the end of an axon?
It reaches the synapse and sends neurotransmitters to start a new impulse to the next neuron
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.
What is pressure trigger?
A pressure trigger is a trigger for initiating assisted ventilation. A pressure trigger consists of a measuring pressure and starting assisted ventilation when the pressure reaches the desired level.
Action potentials originate at the?
Action potentials are how nerve impulses are transmitted from neuron to neuron. An action potential is formed when a stimulus to the nerve cell causes the membrane to depolarize and open all of its sodium ion channels toward the threshold potential.
