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

The nervous system is a multiplexed body system that controls most other body systems directly or indirectly by sending and receiving signals through a complex system of nerves. As a whole, the nervous system can be broken down into the central nervous system (CNS) and peripheral nervous system (PNS). The CNS is composed of the brain and spinal cord while the PNS is composed of peripheral nerves that branch off of the spinal cord and continue to branch to reach the most distal points of the limbs. The PNS can be further broken down into the afferent and efferent division. The afferent division deals with information brought to the CNS from the nerve receptors. Furthermore, the afferent division breaks down into somatic sensory receptors whose

1. Neurons is a basic building block of the nervous system. The sensory nerves carry the message from body tissues to the brain and spinal chord to be processed. The motor neurons are then used to send instructions to the body tissue from the brain and spinal cord. Dendrites, which are connected to the body cell (soma) receive information and pass it through the axon. Myelin sheath covers the axon and helps speed the process. When triggered by a signals from our senses or other neurons, the neuron fires an impulse called the action potential. The resting potential is the neuron’s visual charge of positive

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.

Describe the anatomy of the neuron and the ways that neurons communicate with each other.

* Interneurons or Pseudopolare (Spelling) cells form all the neural wiring within the CNS. These have two axons (instead of an axon and a dendrite). One axon communicates with the spinal cord; one with either the skin or muscle. These neurons have two processes. (Examples are dorsal root ganglia cells.)

Discuss the mechanisms of neural communication and explain the impact that different drugs can have on this communication.

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 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

4.On a neuron, the branch-like structures that receive messages from other neurons are the dendrites.

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).

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

Nerve cells generate electrical signals to transmit information. Neurons are not necessarily intrinsically great electrical conductors, however, they have evolved specialized mechanisms for propagating signals based on the flow of ions across their membranes.

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

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
