Axon

Acetylcholine has two types of receptors: muscarinic and nicotinic, these receptors are functionally and structurally different. Nicotinic receptors are ionotropic, meaning that ions flow through it when acetylcholine binds to it. It acts as a channel for the ions that cross it, especially sodium, and this causes the depolarization of the cell. There are two types of nicotinic receptors formed by different subunits, N1 are found in the neuromuscular junctions allowing muscle movement, and N2 is…

learning. The way they work is by sending electrical or chemical signals between each neuron. Just like anything functional, neurons have certain components that do certain things. Neurons are composed of three parts: a cell body, dendrites, and the axon. A cell body is exactly as it sounds, the body of the cell that holds most everything. It resembles an uprooted tree root mass (Medina, 89). The dendrites are small fibers that can send or receive signals…

Introspection, Behaviorism, and the Cognitive Revolution Introspection and behaviorism both had faults when it came to defining and proving the science of psychology. Introspection fell quickly to its lack of consistency and true measurability. These shortcomings forced the practice to be replaced with the more researchable theory of behaviorism. Behaviorism held dominance over psychology for a few decades, because of the inclination it had towards the truly measurable observations in the field…

The nervous system in the body is divided into Central Nervous System (CNS) and Peripheral Nervous System (PNS). Central nervous system controls all important nerves inside the body enable the body to do its daily tasks. Peripheral nervous system is the system that control on the outside the brain and spinal cord. Both systems are requiring in the body for different functions. The central nervous system consists of the nerves in brain and spinal cord. The brain is responsible for organize and…

Only 1 in 100,000 people have to experience this scarce syndrome; Guillain Barre could possibly temporary have a serious affliction on the individual’s life, some of which we have heard of. Take Franklin D. Roosevelt for example, he suffered from Guillain Barre or also commonly known as “GBS” experienced a fight with this nerve damaging infection. GBS progressively starts to own a person’s life, being educated about this disease, the symptoms and effects, and the treatments will be beneficial.…

My Reflection Paper While completing the first module for neurology there were many aspects of the brain that I was completely unaware of and found interesting. As a speech-language pathologist, it is important for one to know the function of the brain so one can have the skills to help improve the ability for an individual to communicate with others. Damage to certain parts of the brain function can lead to some drastic consequences relating to speech and language functions. I had always found…

The neurotransmitters are from the axon and travel across the synapse. After relaying information, the neurotransmitters revert into the axon by the neurotransmitter reuptake. The reuptake is to protect them from destruction to ensure their reuse whenever necessary. If there were no reuptake, the neurotransmitters would risk exposure to…

both spatial and temporal local patterns of OB circuitry were altered, suggesting a change in strength of synaptic transmission (Spors and Grinvald, 2002). The axon terminals of OR express D2 receptors (D2Rs) and neighbouring juxtaglomerular neurons express dopamine. When the D2Rs are activated in the OB, transmitter release from the OR axons are attenuated, thus decreasing afferent input gain (Reviewed from Wilson et al,…

homeostasis. Diverse Components of a Neuron cell is produced using various part such as axon. Furthermore, it likewise epitomizes the core of the cell. Dendrites have fiber-like surface, where it fills in as an apparatus in gathering of data starting from different neurons. Axon is in charge of transmitting messages from the soma and towards different cells by means of tree-looking branch endings called axon…
