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).
What else can I help you with?
Which type of tissue is specialized for conduction of impulses?
Nervous tissue is specialized for the conduction of impulses, specifically through neurons which transmit electrical signals throughout the body. This tissue is critical for communication within the body and enables functions such as movement, sensation, and cognitive processes.
What tissue type functions in impulse conduction?
Nervous tissue functions in impulse conduction. It consists of neurons that transmit electrical signals or impulses throughout the body. The specialized structure of neurons, including dendrites, axons, and synapses, enables them to rapidly transmit information.
Which cells electrically insulate exons to increase the speed of conduction?
Oligodendrocytes in the central nervous system and Schwann cells in the peripheral nervous system are responsible for electrically insulating axons by forming myelin sheaths around them. This insulation increases the speed of conduction of nerve impulses along the axons.
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 impulse conduction is the fastest in neurons?
Axons conduct the nerve impulses. Dendrites receive the impulses. Possible the impulses go through the dendrites faster, though the synaptic cleft may slow this pathway. Dendrites are much shorter than axons.
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.

What major tissue type transmit electrochemical impulses?
The nervous tissue.
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
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.
