WebJan 17, 2024 · The path taken by the nerve impulses in a reflex is called a reflex arc. In higher animals, most sensory neurons do not pass directly into the brain, but synapse in the spinal cord. ... The stimulus, such as a needle stick, stimulates the pain receptors of the skin, which initiate an impulse in a sensory neuron. This travels to the spinal cord ... WebNov 19, 2024 · This process, which occurs during the firing of the neurons, allows a nerve cell to transmit an electrical signal down the axon (a portion of the neuron that carries nerve impulses away from the cell body) …

Transmission of signals internally between the cells is achieved through a synapse. Nerve conductors comprise relatively higher membrane resistance and low axial resistance.
WebThe neurotransmitters are absorbed by the nerve fibres located at the basal end of the hair cell, stimulating them to send an electrical signal along the cochlear nerve. The outer hair cells contain both actin and myosin, the … WebYour body has nerves that connect your brain to the rest of your organs and muscles, just …
WebThe movement of the action potential down the length of the axon is an electrical event, and movement of the neurotransmitter across the synaptic space represents the chemical portion of the process. However, there are some specialized connections between neurons that are entirely electrical. WebJul 10, 2024 · Nerve impulses are received at neuronal dendrites, passed through the cell …
