How Are Neurons Specialized For Communication? How Do Not Go Off Track Or Give?

3.The long tube-like structure that carries the neural message to other cells on the neuron is the axon.

Neurons are nerve cells that transmit nerve signals to and from the brain at up to 200 mph. The neuron consists of a cell body (or soma) with branching dendrites(signal receivers) and a projection called

As well as these there are also the axon of the cell which is covered in myelin sheaths which carried information away from the cell body and hands the action potentials, these are small short bursts of change in the electrical charge of the axon membrane through openings of ion channels, off to the following neurons dendrites through terminal buttons at the end of the axons. Whenever an action potential is passed through these terminal buttons it releases a chemicals that pass on the action potential on to the next neuron through the terminal button and dendrite connection. The chemicals that are

Among various types of organ systems, the nervous system is one of the most important one in human body. It is responsible for producing, controlling and guiding our thoughts and responses to the world around us according to James W. Pennebaker (2012). During embryological development, the cells that form nervous system are incredibly specialised and work complexly than the cells that form skin or other body parts. Neurosecretory cells are one of the examples of specialised nervous system cells that produce neurosecretions. Neurosecretions are hormones which carry information from sensor cells to target cells and they can be released directly into the bloodstream

Neurons, nerve cells, have three basic parts: the cell body, dendrites, and axon. Neurons transmit signals to other nerve cells and throughout the body. They are simple components in the nervous system. The cell body includes the nucleus, which is the control center of the neuron. The dendrite branches off the cell body and receives information. The axon is attached to the cell body and sends information away from the cell body to other cells. When the axon goes through myelination, the axon part of the neuron becomes covered and insulated with fat cells, myelin sheath. This increases the speed and efficiency of information processing in the nervous system. Synapse are gaps between neurons, this is where connections between the axons and dendrites.

Neuropsychology is another field in which both psychology and biology play a major role. Neuropsychology studies the structure and function of the brain as it relates to specific psychological processes and behaviors. It is a clinical and experimental field of psychology that aims to study, assess, understand and treat behaviors directly related to brain functioning. Neuropsychology studies and applies research to the functions and the dysfunctions of the brain and how they affect the body as well as the personality. This has helped us to not only define mental disorders and cognitive impairments, but to develop different treatment

2.Dendrite are the receptive region of the neuron. They conduct electrical impulses toward the cell body.

The cell body comprises of the nucleus and other organelles (Ward, 2010). The nucleus contains the genetic code, and this is involved with protein synthesis (He, 2013). The dendrites receive information from other neurons which are located in a close proximity (Kalat, 1995). The terminal of an axon compresses into a disc-shaped structure (Gross, 2010). This is where chemical signals also known as a neurotransmitter permit interaction amongst neurons, by means of a minute gap named a synapse (Martin, Carlson & Buskit, 2013). Both neurons which form the synapse are referred to as a presynaptic synapse (prior to the synapse) and postsynaptic (after the synapse), reflecting the direction of information flow (from axon to dendrite), (He, 2013).

2. Think about whether or not everyone 's synapses develop the same because of genetics (nature) or the environment (nurture). Please explain the role that genetics (nature) and the environment (nurture) play in the development of the six (6) major components of the synapse. Do this by listing and providing a brief summary of the six (6) major components. Then, describe how genetics (nature) and the environment (nurture) might affect the development of the six (6) major components as a whole.

Neurons (also known as neurons, nerve cells and nerve fibers) are electrically excitable and the most important cells in the nervous system that functions to process and transmit information. Neurons have a large number of extensions called dendrites. They often look likes branches or spikes extending out from the cell body. It is primarily the surfaces of the dendrites that receive chemical messages from other neurons.

Neurons are what make up the nervous system. The nervous system is very complex for all the activities that this system performs. It main function is to communicate. It sends nerve impulses to the muscles (effectors), the muscles receive stimuli and tuned electromechanical signals that are sent to the

The human nervous system is divided into two main networks that work in harmony with each other. First, the Central Nervous System that consists of the brain and the spinal cord, and the Peripheral Nervous System that is made up of the nerves comings out of that Central Nervous System. The Central Nervous System’s main task is to integrate sensory information that the Peripheral Nervous System collects from all over the body and responds to it by coordinating both conscious and unconscious activity. In the Central Nervous System, the brain is responsible for sorting through all in coming sensory information, giving orders to other parts of the body, and carries out the complex functions of thinking, feeling and remembering. While, the spinal

Our nervous system and brain interact as we cope with our immediate environment. Thus, it transmits and receives our sensory inputs such as sounds, sight, smells and feelings. One end of each neuron on the nerve endings are enclosed in a structure created to sense a specific stimulus. Sending sensory information to the brain or spinal cord is performed by the nervous system. Nervous system is divided into two main systems: Central nervous system and Peripheral nervous system (Saladin, 2014). The central nervous system consists of the spinal cord and brain, the brain which is divided into four lobes (parietal, frontal, temporal and occipital). Spinal cord and brain work together even though there are some occasions when the spinal cord acts earlier before the brain gets the information.

These procedures involved in cognitive neuroscience require high levels of control, therefore are usually conducted in a laboratory setting, thus producing quantitative data that can be easily analysed, (Eysenck and Keane, 2010). Nevertheless, the techniques vary in the precision with which they identify the brain areas active when a task is performed (spatial resolution), and the time course of such activation (temporal resolution).Therefore, several procedures often need to be combined to compensate for limitations, (Sternberg and Wagner, 1999).

The human nervous system is divided into two parts, the central nervous system and the peripheral nervous system. The central nervous system, CNS, is just the brain and spinal cord. The peripheral nervous system, PNS, includes the nerves and neurons that extend outwards from CNS, to transmit information to your limbs and organs for example. Communication between your cells is extremely important, neurons are the messengers that relay information to and from your brain.
