The primary function of a nerve cell, also known as a neuron, in a multicellular organism is to carry and transmit signals. Neurons are specialized cells that communicate with each other and with other cells in the body to transmit electrical impulses. These impulses travel along the length of the neuron and can be transmitted to other neurons, muscle cells, or gland cells, allowing for communication and coordination within the organism's body. Neurons play a crucial role in processes such as sensory perception, motor control, and overall communication within the nervous system. The production and distribution of oxygen is primarily carried out by red blood cells and is not a specific function of nerve cells.
The correct response is: "carry and transmit signals".
Nerve cells, also known as neurons, have a vital role in multicellular organisms by carrying and transmitting signals throughout the body. They are specialized cells that are responsible for the communication between different parts of the body and enable the efficient coordination of various physiological processes.
To arrive at this answer, you can consider the function of nerve cells within the context of their structure and knowledge of how the nervous system works. Nerve cells have elongated projections called axons, which are responsible for transmitting electrical signals, known as action potentials, over long distances. These signals can travel from one nerve cell to another, enabling communication between different cells and organs.
Furthermore, nerve cells have specialized structures called synapses, which allow them to communicate with other cells, such as muscle cells or other neurons, by releasing chemical messengers called neurotransmitters. This enables coordination of movements, sensory perception, and the regulation of various body functions.
In summary, nerve cells in multicellular organisms play a crucial role in carrying and transmitting signals, allowing for efficient communication and coordination within the body.
