What neuron moves the impulses to the brain?
The brain is the control, and the whole reaction of a reflex arc starts with a stimulus, ie, touching a hot flame, the detector of this stimulus being the receptor. The electrical impulses travel through the sensory neuron to which it is then carried to the synapse (impulses reach the brain) the energy is then transferred across the synapse, to the relay neuron and then to the motor neuron, finally reaching the effector, (mainly muscle or gland) to move away the body part.
How does the myelin sheath and synapse affect nerve impulses speed up or slow down?
The myelin sheath acts as an insulating layer that helps speed up nerve impulses by allowing them to "jump" between gaps in the sheath called nodes of Ranvier. This process, known as saltatory conduction, accelerates the transmission of nerve impulses along the axon. At the synapse, neurotransmitters are released to transmit signals between neurons. The efficiency of this process can also affect the speed of nerve impulse transmission.
Which one of the following phrases describes the transmission of impulses to and from nerve cells?
There is a connection between two brain cells, called a synapse. When it reaches the end of one cell, the electric impulse transforms itself into a chemical substance, and is transferred from one cell to another. When it reaches the second cell, it is again transformed intro an electric impulse.
What kinds of compounds in the body transmit impulses between nerve and muscle cells?
Neurotransmitters such as acetylcholine transmit impulses between nerve and muscle cells. These chemical messengers are released at the synapse where nerve and muscle cells meet, allowing for the transmission of signals that trigger muscle contraction.
Important synapse site for afferent fibers traveling to the sensory cortex?
Thalamus is the important synapse site for afferent fibers traveling to the sensory cortex. It acts as a relay station, processing sensory information before transmitting it to the appropriate areas of the sensory cortex for further processing and perception.
What any drug that inhibits transmission of sensory impulses at a synapse called?
Drugs that inhibit neurotransmission at the site are called analgesics. Opioids are the most common type of this drug.
What is any drug that inhibits trans mission of sensory impulse at a synapse called?
Pain medication
What structure transmits impulses from a receptor organ to an interneuron?
The structure that transmits impulses from a receptor organ to an interneuron is the sensory neuron. When a receptor organ detects a stimulus, it generates an electrical signal that travels along the sensory neuron's axon. This signal then reaches the synapse with the interneuron, facilitating the transmission of the impulse to the central nervous system for processing.
Neural transmission across a mammalian synaptic gap is accomplished by?
impulses causing the release of a chemical signal and its diffusion across the synapse.
What neuron moves the impulses to the brain?
The brain is the control, and the whole reaction of a reflex arc starts with a stimulus, ie, touching a hot flame, the detector of this stimulus being the receptor. The electrical impulses travel through the sensory neuron to which it is then carried to the synapse (impulses reach the brain) the energy is then transferred across the synapse, to the relay neuron and then to the motor neuron, finally reaching the effector, (mainly muscle or gland) to move away the body part.
Can impulses pass in 2 directions across a synapse?
no
Are motor neurons an electrical synapse?
no,motor neurons are not electrical synapse but are normal nerve cells.they help in transmission of electrical impulses from the site of stimulus towards the spinal cord.the impulses have to travel and cross certain spaces or junctions between two consecutive nerves,the axon bulb of one to dendrites of next neuron.
What is the space between two adjacent nerve cells?
its known as the synapse. Through the synapse is where impulses travel from brain cell to brain cell.
What is the small space between neurons where impulses pass?
Synapse

What interprets messages transmitted by sensory neurons?
it was the synapse
What is the space that impulses jump across by means of a transmitting chemical?
synapse
