What are the two types of messages a neuron can send?
Excitatory and inhibitory messages. Excitatory messages increase the likelihood of a postsynaptic neuron firing an action potential, while inhibitory messages decrease this likelihood.
How are motor neuron diseases diagnosed?
often based upon symptoms and exclusion of other neurological diseases. Nerve conduction studies can help distinguish some forms of peripheral neuropathy from motor neuron disease
Functional connection between two neurons is a?
functional connection between two neurons is the transmission of electrical signals from one neuron to another through a synapse. When an electrical impulse reaches the axon terminal of the pre-synaptic neuron, it triggers the release of neurotransmitters into the synaptic cleft. These neurotransmitters then bind to receptors on the post-synaptic neuron, allowing the electrical signal to be transmitted and continue the communication between neurons.
The space between two neurons or between a neuron and a receptor is known as a?
The space between two neurons or between a neuron and a receptor is known as a synapse. In this gap, neurotransmitters are released from the presynaptic neuron and bind to receptors on the postsynaptic neuron, allowing for communication between the two cells.
Which does not constitute part of a two-neuron reflex?
A two-neuron reflex typically involves a sensory neuron carrying information from a sensory receptor to the spinal cord, where it synapses with an interneuron. The interneuron then synapses with a motor neuron that carries the response signal to an effector organ, such as a muscle or gland. In this pathway, a third neuron would not typically be involved in a two-neuron reflex.
What happens if myelin sheath is damage?
Two things, 1, the conduction speed of the neuron will be reduced. 2, the neuron will be subject to 'activation' from extraneous sources.
What are the two types of fibers that project from a neuron's cell body?
The two fibers that a neuron has are the nerve and the myelin fibers
What is the 3 types of neuron?
one type of neuron is the motor neuron
What is The depolarization and repolarization of a neuron membrane called?
This process is called nerve conduction.
Does Saltatory conduction occurs because of the presence of salt NaCl around the neuron?
No, saltatory conduction is not due to the presence of NaCl (sodium chloride) around the neuron. It is a process in which nerve impulses jump from one node of Ranvier to another in myelinated neurons, speeding up the conduction of the signal. The presence of myelin sheath around the neuron helps facilitate this rapid transmission.
What type of neuron is in the nervous system?
There are 3 types, the motor neuron, the sensory neuron, and the interneuron
Which neuron have maximum saltatory conduction?
Those neurons with mylenated fibers on the axon have the fastest response.
What is the neurons of the nervous system?
There are 3 types, the motor neuron, the sensory neuron, and the interneuron
Are the nodes of ranvier only found on myelinated peripheral neuron processes?
Yes.
Where does nerve conduction deafness occur?
Nerve conduction deafness is one of the two types of deafness that can happen. It occurs when there is a break in communication between the nerve cells and the inner ear.
Is the axon the conduction component of a neuron?
Yes, the axon conducts the action potential from the cell body to the effector organ.
What neuron types are unipolar?
Small ones
