WebNerve impulse propagates by jumping from one node of Ranvier to the next. This makes the process of nerve impulse faster as the nerve impulse does not travel the entire length of the axon ( this happens in case of continuous conduction). The nerve impulse travels at a speed of 100 m/s in saltatory conduction. WebThe axon hillock is located where the cell body transitions into the axon. Axons can branch in order to communicate with more than one target cell. Figure 1.4. The axon is a long single projection that begins at the axon hillock, the region between the cell body and the axon. The axon terminates at the presynaptic terminal.
An axon (from Greek ἄξων áxōn, axis), or nerve fiber (or nerve fibre: see spelling differences), is a long, slender projection of a nerve cell, or neuron, in vertebrates, that typically conducts electrical impulses known as action potentials away from the nerve cell body. The function of the axon is to transmit information to different neurons, muscles, and glands. In certain sensory neurons (pseudounipolar neurons), such as those for touch and warmth, the axons are called afferent ner… WebJun 12, 2024 · Axon terminal and synapse.
