hi
do dendrites generate or conduct impulses
and do axons transmit to and from the cell body or do they transmit it away.
thanks jim
The neuron cell body and the dendrites are the recipients of the stimulation from other cells. Once a neuron fires, it goes in all directions within the neuron, like the ripples on a pond. However, transmission to other cells only occurs at the ends of the axons.
I hope this helps a little more. Thanks for asking.
thanks.
ok heres what i got from the book.
the post synaptic neuron receives a chemical signal and generates the electrical signal.
for the axon problem my teacher said sensory neurons transmit a signal along its axon to the cell body. The motor neuron tranmits a electrical signal away from the cell body to an effector.
thanks.
Hello Jim!
Dendrites are responsible for receiving electrical signals, called impulses, from neighboring cells or sensory organs. They generate graded potentials, which are small changes in the electrical potential across the cell membrane. These graded potentials are then integrated at the cell body before being transmitted further along the neuron.
Axons, on the other hand, are responsible for conducting the electrical impulses away from the cell body. Once the electrical signal reaches the initial segment of the axon, known as the axon hillock, it is converted into a rapid, all-or-nothing action potential that propagates along the entire length of the axon.
To summarize:
- Dendrites generate graded potentials in response to incoming signals.
- Axons transmit these electrical impulses away from the cell body.
If you're interested in further exploring this topic, I recommend studying neuroscience or examining biology textbooks that cover the structure and function of neurons in more detail.
