Which element is necessary for proper conduction of nervous impulses?

The nervous system relies on more rapid mechanisms of chemical and electrical transmission to propagate signals and commands. The rapid conduction of impulses is essential in allowing the nervous system to mediate short-term and near immediate communication and control between various body systems.
Nerve cells are specialized so that at one end there is a flared structure termed the dendrite. At the dendrite, the neuron is able to process chemical signals from other neurons and endocrine hormones. If the signals received at the dendrite end of the neuron are of a sufficient strength, and properly timed, they are transformed into action potentials that sweep down the neural cell body (axon) from the dendrite end to the other end of the neuron, the presynaptic portion of the axon that ends at the next synapse (the extra cellular gap between neurons)in the neural pathway. The arrival of the action potential at the presynaptic terminus causes the release of ions and chemicals (neurotransmitters).

Which type of tissue is specialized for conduction of impulses?
Nervous System
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.
Why are lipids necessary for your body?
They are necessary because they have a structural role in membranes and store energy for later use to help the brain transmit nervous impulses and regulate the function of the body.
How are nervous impulses translated?

Why is the conduction of impulses slow in autonomic nervous system?
Because there is no need for a fast transmission, in most cases, of the chemical messengers (hormones). Therefore, the nerve cells are unmyelinated and send their signal in a continuous transmission.
What has the author Alan Lloyd Hodgkin written?
Alan Lloyd Hodgkin has written: 'The conduction of the nervous impluse' -- subject(s): Nervous system 'The conduction of the nervous impulse' -- subject(s): Nervous system
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 carry instructions from the central nervous system to effector organs?
The peripheral nervous system carries impulses from the central nervous system to the effectors.
What type of nervous system conduction occurs in myelinated axons?
Saltatory Conduction
