WitrynaWhen the nerve impulse arrives at the synapse, it may cause the release of neurotransmitters, which influence another (postsynaptic) neuron. The postsynaptic neuron may receive inputs from many additional neurons, both excitatory and inhibitory. Witryna4 wrz 2024 · The cell that sends the nerve impulse is called the presynaptic cell, and the cell that receives the nerve impulse is called the postsynaptic cell. Some synapses are purely electrical and make direct electrical connections between neurons.

Witryna24 cze 2024 · The first step of cardiac conduction is impulse generation. The sinoatrial (SA) node (also referred to as the pacemaker of the heart) contracts, generating nerve impulses that travel throughout the heart …

Witryna5 mar 2024 · A nerve impulse begins when a neuron receives a chemical stimulus. The nerve impulse travels down the axon membrane as an electrical action potential to … WitrynaNerve impulses are transmitted from the ear to the brain via the auditory nerves, one of the several sensory nerves that exists in the group of nerves known as cranial nerves. The auditory nerves connect the nerve impulses of the ears to the upper "temporal lobe" of the "cerebral cortex". Nerve impulses pass over "neurons" via

WitrynaNerve impulses are action potentials that travel along membranes. The voltage of nerve impulses is approximately +30 mV. Upon completion of the action potential, the sodium-potassium pump begins to operate. Repolarization will ultimately result in a resting potential for the axon membrane. In reverse order, the process occurs now.
