Dendrites are branching extensions of neurons that receive signals from other nerve cells. They play a crucial role in transmitting electrical impulses toward the cell body, facilitating communication within the nervous system. By increasing the surface area available for synaptic connections, dendrites enhance a neuron's ability to process and integrate information.

What is the function of the dentrites?

Dendrites are attaches to the axon terminals of other neurons. The nerve impulse travel from other neurons into the corresponding neuron via dendrites.


Which elongated cell can conduct impulses?

A neuron is an elongated cell that can conduct impulses. Neurons have specialized structures called axons that transmit electrical signals over long distances within the body.


What does nerve cells look like?

Neurons are of three types (shapes) Unipolar: they have a cell body (soma) and a single process (axon and a dentrite) Bipolar: they have a cell body and an axon and a dentrite on opposite poles. Multipolar:they have a cell body, axon and more than two dentrites.


What cell transmits and receive nervous-system signals?

The dendrites collect information from other cells (afferent) or send information to other cells (efferent). The afferent dentrites are stimulated by chmicals from sensory cells. The efferent dentrites send chemical signals to other cells.


How are axons similar to dentrites?

Axons and dendrites are both extensions of neurons responsible for transmitting electrical signals. However, axons transmit signals away from the cell body, while dendrites receive signals and transmit them toward the cell body. Both play crucial roles in the communication between neurons.


Can a neuron have more than two axons?

No, a neuron typically has only one axon which carries nerve impulses away from the cell body. However, certain types of neurons, such as those in invertebrates, can have multiple axon-like processes known as neurites that function in a similar way to axons.


Dentrites are branching extensions of?

Dendrites are branching extensions of neurons that receive signals from other neurons. They play a crucial role in transmitting electrical impulses toward the cell body, facilitating communication within the nervous system. By increasing the surface area of the neuron, dendrites enhance its ability to connect with multiple synapses and integrate information.


Unused dendrites die off?

Unused dendrites in the brain can undergo a process called pruning, where they are eliminated to make the brain more efficient. This allows for stronger connections to be established and maintained. However, this process does not result in cell death, but rather the reorganization of neural networks.

What are the functions of the dentrites?

Dendrites are specialized extensions of neurons that play a crucial role in receiving and integrating signals from other neurons. They contain numerous receptors that detect neurotransmitters released at synapses, allowing for the transmission of information. By processing these signals, dendrites contribute to the overall excitability of the neuron and help determine whether an action potential will be generated. Additionally, dendrites can undergo structural changes in response to activity, which is important for learning and memory.
