Nervous impulses are sped up primarily by the myelin sheath, a fatty insulating layer that surrounds the axons of many neurons. This myelination allows impulses to jump between gaps in the sheath, known as nodes of Ranvier, through a process called saltatory conduction. Additionally, the diameter of the axon plays a role, as larger diameters can conduct impulses more quickly due to reduced resistance. Overall, both myelination and axon diameter are key factors in increasing the speed of nerve transmission.

What do electrical impulses of the brain cause?
Electrical impulses of the brain are the nervous impulses that the nervous system uses to control body functions. These impulses may be relayed within the brain, or may be carried to the peripheral nervous system.

What is the neurrons job in the nervous system?
to send impulses they are the cells of the nervous system. Wikipedia is a good site to look up neurons and nerve cells.
What major tissue type transmit electrochemical impulses?
The nervous tissue.
Which part of the nervous system carries impulses between the body and the central?
The peripheral nervous system carries impulses between the spinal cord and other body parts.
What is the difference between afferent and efferent pathways?
The major difference is the direction of travel for nerve impulses. In the afferent nervous system, the impulses are traveling away from the brain - these tend to be motor impulses. In the efferent nervous system, the impulses are traveling towards the brain - these tend to be sensory impulses.
What divisions of the nervous system sends impulses from your brain to your heart?
autonomic nervous system
Does nervous tissue transmit electrochemical impulses?
Yes
