What else can I help you with?
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.
The point of communication between two neurons?
The point of communication between two neurons is called a synapse. At the synapse, the sending neuron releases neurotransmitters into the tiny gap between the two neurons, which then bind to receptors on the receiving neuron, triggering an electrical signal to be sent down the receiving neuron. This process allows for communication and transmission of information between neurons in the brain and nervous system.
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).
What is the point where two nerve processes meet?
The point where two nerve processes meet is called a synapse. At the synapse, a chemical or electrical signal is transmitted from one neuron to another, allowing for communication between nerve cells in the nervous system.
How does sensory impulse move throughout the body?
Sensory impulses travel through sensory neurons from the sensory receptors to the spinal cord and then to the brain for processing. The impulses are transmitted as electrical signals and travel along the neurons using a combination of electrical and chemical signals. Once the brain processes the sensory information, it generates a response that is transmitted back through motor neurons to carry out appropriate actions.
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.
The point of contract between the nerve ending and the muscle fiber is called a motor neuron?
Neuromuscular junction (NMJ)
What is the point of contact between a motor neuron and a skeletal muscle cell called?
This point is often called the neuromuscular junction or motor end plate. ?The neurotransmitter used here is acetylcholine.Many diseases occur with dysfunction at this junction, like Myesthenia Gravis, botulism, or Lambert Eaton Myasthenic Syndrome.
The point of communication between two neurons?
The point of communication between two neurons is called a synapse. At the synapse, the sending neuron releases neurotransmitters into the tiny gap between the two neurons, which then bind to receptors on the receiving neuron, triggering an electrical signal to be sent down the receiving neuron. This process allows for communication and transmission of information between neurons in the brain and nervous system.
What alters neurons and synapses to the point that they can not function without a drug?
hi
What triggers at a point in which a neuron will fire?
Threshold
What part of a muscle fiber junctions with a motor neuron?
There is no junction. Motor neurons are riddled throughout the muscle spindles. Every muscle spindle has a nerve supply or it would not function. think about the way capilaries infiltrate mucles, it's pretty finite. when you are talking about the neurons you are talking about a finite thing, there are billions of them in your body.
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).
What are the sequence of events that occur within the nervous system from the point you touched the hot stove with your hand to the point you jerked your hand away from the stove?
1. Sensory Receptors detect danger(eg. hot stove in this case) 2. Signal is sent through a sensory neuron to the spinal cord 3.Interneuron in the spinal cord relays the message to the motor neuron 4.Motor neuron sends a message to the effector(eg. muscle) 5. Hand jerks away Sensory neuron also sends a sinal to the brain. Sensation of the evernt is detected continuosly but usually after the defensive action has been taken.
What is a junction or point of close contact between neuron?
A junction or point of close contact between neurons is called a synapse. It is where electrical or chemical signals are transmitted from one neuron to another. Neurotransmitters are released from the presynaptic neuron to the postsynaptic neuron to carry out this communication.
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.
When a stimulus acts on a neuron it decreases the permeability of the stimulated point of its membrane to sodium ions?
False( When a stimulus acts on a neuron, it increases the permeability of the stimulated point of its membrane to sodium ions. )
