Introduction to Neuroanatomy

Coursework Instructions:

Address the following Short Answer prompts for your Assignment. Be sure to include references to the Learning Resources for this week.
1. In 4 or 5 sentences, describe the anatomy of the basic unit of the nervous system, the neuron. Include each part of the neuron and a general overview of electrical impulse conduction, the pathway it travels, and the net result at the termination of the impulse. Be specific and provide examples.
2. Answer the following (listing is acceptable for these questions):
. What are the major components that make up the subcortical structures?
Which component plays a role in learning, memory, and addiction?
What are the two key neurotransmitters located in the nigra striatal region of the brain that play a major role in motor control?
3. In 3 or 4 sentences, explain how glia cells function in the central nervous system. Be specific and provide examples.
4. The synapse is an area between two neurons that allows for chemical communication. In 3 or 4 sentences, explain what part of the neurons are communicating with each other and in which direction does this communication occur? Be specific.
5. In 3–5 sentences, explain the concept of “neuroplasticity.” Be specific and provide examples.
Watch out for excessive use of plagiarism.

Question 1
The neuron is the fundamental unit of the nervous system and is made up of dendrites, axons, and soma. The dendrites receive signals from other cells while the axon transmits electrical impulses to other cells. The soma houses the nucleus and makes proteins transported to the axon and dendrites (Duncan, Simkins, & Emery, 2021). For instance, when a neuron wants to communicate to another cell, it sends a message called action potential through the axon, causing neurotransmitter release into the synapse. The dendrites of the receiving neuron receive synaptic inputs from other cells for processing.
Question 2
* Subcortical structures are a cluster of different neural structures that are deep within the brain. The major components of subcortical structures are limbic structures and the pituitary gland, basal ganglia, as well as diencephalon. 
* The limbic system is important in learning, memory, and addiction. The two major components of the limbic system responsible are the hippocampus and amygdala.
* Dopamine and GABA are the two main neurotransmitters located in the nigra striatal region of the brain that has a vital purpose in motor control (Jamwal & Kumar, 2019). Dopamine is produced in the substantia nigra pars compacta (SNc) neurons and stimulates movement. GABA from the substantia nigra pars reticulata (SNr) can inhibit or stimulate movement depending on the signal.
Question 3
Glia cells are non-neuronal cells that do not produce electrical impulses. Glia cells in the central nervous system (CNS) include astrocytes, ependymal cells, oligodendrocytes, and microglia cells. The astrocytes are joined with the neurons and capillaries in the CNS, and they bring forth nutrients to the neurons in the CNS to form a blood-brain barrier. Astrocytes also control the concentration of ions in the fluid outside the cells and offer support to synapses. Microglia destroy cells that are dead and offer protection for the brain against any kind of microorganisms. that may invade. Oligodendrocytes form protective myelin sheaths around the axons of ...
