Which part of the neuron acts like an antenna to receive messages?

Which part of the neuron acts like an antenna to receive messages?

Dendrites are part of a neuron acts like an antenna to receive messages from other neurons and transmits these messages toward the cell body.

Which is used as an antennas receiving messages from other nerve cells and transmitting them toward the cell body?

Dendrites receive information from another cell and transmit the message to the cell body. The cell body contains the nucleus, mitochondria and other organelles typical of eukaryotic cells.

What are cells that transmit messages called?

A special cell called a neuron is responsible for carrying these messages. There are about 100 billion neurons in the human brain.

What cells transmit messages from the brain to the muscles?

Single nerve cells in the spinal cord, called motor neurons, are the only way the brain connects to muscles. When a motor neuron inside the spinal cord fires, an impulse goes out from it to the muscles on a long, very thin extension of that single cell called an axon.

What happens when a neuron sends a signal?

A triggering event occurs that depolarizes the cell body. This signal comes from other cells connecting to the neuron, and it causes positively charged ions to flow into the cell body. These incoming ions bring the membrane potential closer to 0, which is known as depolarization.

What is the function of nerve cell or neuron Class 8?

Cell — Structure and Functions | Exercise The nerve cell(neuron) receives and transfers messages, thereby helping to control and coordinate the working of different parts of the body.

How does a neuron send a signal?

A neuron sending a signal (i.e., a presynaptic neuron) releases a chemical called a neurotransmitter, which binds to a receptor on the surface of the receiving (i.e., postsynaptic) neuron. Neurotransmitters are released from presynaptic terminals, which may branch to communicate with several postsynaptic neurons.
