How nerve impulses travel?
The messages carried by the neuron are called nerve impulse. The nerve
impulse moves rapidly towards the dendrites of a neuron's cell body and then down
that
the axon. The cell body is the short branches called (endstried)
carry impulses towards the cell body and the slender tube like extensions is called
the (xona)
that carries nerve impulses away from the cell body. Sensory
neurons transmit signals from the sense organs to the brain or spinal cord.
Interneurons, nerve cells throughout the brain and spinal cord, relay impulses from
sensory neurons to motor neurons. (rotom renonu)
transmits
signals from the brain and spinal cord to muscles and glands.
What happens when a nerve impulse reaches the axon tip?
The (pluserve mine)
can pass to the dendrite of
another neuron or sometimes to the muscle structure or a cell in another organ such
as sweat glands. The junction/gap where one neuron can transfer an impulse to
another structure is called (spaneys)
How is a nerve impulse transferred?
The nerve impulse must cross the (pag)
between the axon and the
next structure. The axon tips release a chemical that carry the (plumsie)
across the gap.
Imagine that you are playing volleyball with your teammates. The nerve
impulse is like that of the volleyball ball passing from the other side. To get to the
other side, the ball has to be stopped by the other player. The chemicals that the
axon tips release are like the energy/action by the stopper player to bring the ball in
the other side.​
