A neuron or a nerve cell, carries electrical impulses. Relay neurons carry messages from one part of the central nervous system to another.

Neurons are specialized cells that transmit electrical and chemical signals throughout the nervous system to communicate messages. They communicate through the release of neurotransmitters at synapses, enabling the transmission of information across the brain and body.

What is the smallest functional unit of the nervous system?
The neuron is the smallest functional unit of the nervous system. It is responsible for transmitting information through electrical and chemical signals. Neurons make up the basic building blocks of the nervous system and are essential for communication within the brain and between the brain and the rest of the body.
How does the nervous system influence the behavior of individual?
The nervous system plays a fundamental role in regulating behavior by processing sensory information, coordinating motor responses, and facilitating communication between different parts of the brain. This system helps control emotions, decision-making, and reactions to external stimuli, ultimately influencing an individual's actions and responses to the environment. Additionally, neurotransmitters and neural circuits within the nervous system can impact mood, memory, and overall cognitive function, all of which contribute to an individual's behaviors.
Communication within a neuron is electrical while communication between neurons is chemical.?
Yes, that's correct. Within a neuron, communication occurs through electrical signals that travel along the neuron's axon. When these signals reach the synapse (junction between neurons), they trigger the release of chemical neurotransmitters that carry the signal to the next neuron.
What is happening when you are thinking?
When you are thinking, neurons in your brain are firing; they are caused to fire by inputs from the firing of other connected neurons, and the outputs of their firing causes other connected neurons to fire. However, since neurons have MANY MANY connections to many other neurons, any particular neuron is not SIMPLY or absolutely caused to fire just because one connected neuron fires, nor does its firing absolutely cause every neuron it connects to to fire; rather, neurons remember (through physical changes at synapses) which inputs have in combination been strong enough to cause them to fire, making them more sensitive and therefore likely to fire from a variety of similar inputs. Thus thinking is a neuro-chemical memory process, in which memories lead to memories by associations from within and without, and evoke ideas & concepts through novel combinations.
How do drugs produce their effects on human behavior?
Drugs produce their effects on human behavior by interacting with the central nervous system. They can alter neurotransmitter levels, affect brain activity, and influence the brain's reward system, leading to changes in mood, behavior, and perception. These effects can vary depending on the type of drug and its mechanism of action.
The basic cell that makes up the nervous system and which receives and sends messages within that system is called a?
Neurons are the cells that make up the nervous system.
What neuron is found only within the central nervous system?
Interneurons or associative neurons(connecting or relaying neurons)
Interneurons connect sensory and motor neurons within the what?
Central Nervous System!
Why is the nervous system so slow compared to the endodrine system?
It's not, the nervous system is much faster than the endocrine system.The nature of the messages. The nervous system's messages are transported as electrical impulses/neurotransmitters, whereas the endocrine system transports messages as hormonesThe transport of the messages. The messages in the nervous system are transported along the membrane of neurons. The endocrine system transports hormones though the bloodstreamBecause of this, the nervous system usually produces a response within milliseconds, whereas the endocrine system may take seconds to days to respond. The duration of the response also differs between the two systems, the nervous system stops quickly after the stimulant stops, but the endocrine response may continue after the stimulus is removed.
What are the specialized cells that make up nervous tissue?
The brain, spinal cord, neurons and basically anything that can send message from your brain to the rest of your body like your nerves. The nervous system has two subdivisions--the central nervous system and the peripheral nervous system. The Peripheral Nervous system (PNS) is what the Central Nervous System (CNS) sends signals to move the body or control hormones etc...
Which system sends and receives messages within the body?
There isn't any. You're thinking of the nervous system - but the messages are all chemical. The electrical activity is a side effect.
What are inter neurons?
A nerve cell found entirely within the central nervous system that acts as a link between sensory neurons and motor neurons.
How is myelin formed within the central nervous system?
The glial cells that surround the neurons produce myelin.
How does transmission occur in the Central Nervous System?
Transmission of data occurs within our Central nervous system by means of Neurons.there are mainly three types of neuronsSensory neuronsmotor neuronsinter neurons
What are the cells in the nervous system called?
Brain cell is a generic term for the neurons and glial cells. Neurons are nerve cells that process and transmit information through the nervous system. Glial cells provide support, protection, and nutrition to the neurons. Other cells in the brain include epithelial cells that make up the lining of the blood vessels.Source- Wikipedia
What is a nerve system?
The nervous system is a network of specialized cells that communicate information about an animal's surroundings and itself. It processes this information and causes reactions in other parts of the body. It is composed of neurons and other specialized cells called glia, that aid in the function of the neurons. The nervous system is divided broadly into two categories: the peripheral nervous system and the central nervous system. Neurons generate and conduct impulses between and within the two systems. The peripheral nervous system is composed of sensory neurons and the neurons that connect them to the nerve cord, spinal cord and brain, which make up the central nervous system. In response to stimuli, sensory neurons generate and propagate signals to the central nervous system which then processes and conducts signals back to the muscles and glands. The neurons of the nervous systems of animals are interconnected in complex arrangements and use electrochemical signals and neurotransmitters to transmit impulses from one neuron to the next. The interaction of the different neurons form neural circuits that regulate an organism's perception of the world and what is going on with its body, thus regulating its behavior. Nervous systems are found in many multicellular animals but differ greatly in complexity between species.
Who do three different types of neurons function?
motor neuron: neurons that relay signals from the central nervous system to the other parts of the bodysensory neuron: neurons that transmit information to the central nervous system from the senses of sight, hearing, taste, touch, and smell, as well as those that transmit pain signalsinter neurons: relay signals between neurons or groups of neurons, are responsible for the processing of information by the brain, like the logic circuits of a computer. Also serve to relay signals from place to place within the central nervous system.I was going to make a correction but there is none to be made.
