Short Answer Assessment
- 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.
The neuron is the basic unit of the nervous system. It is made up of a cell body containing nucleus cells, axons and dendrites. NURS 6630 week 1 Assignment: Short Answer Assessment It sends and receives signals from the brain. Axons are specialized projections that help neurons in transmitting chemical and electrical signals to other body cells. Communications from other body cells are received by the appendages like structures called dendrites. Electrical impulses are transmitted through the dendrites to the cell body then axon and to the synapse (Camprodon & Roffman, 2016). For instance, when one places a sharp needle on the skin and tries to penetrate one responds to the stimuli by removing the body part from the sharp needle.
- Answer the following (listing is acceptable for these questions):
What are the major components that make up the subcortical structures?
Basal ganglia, limbic structures, pituitary glands and diencephalon NURS 6630 week 1 Assignment: Short Answer Assessment
Which component plays a role in learning, memory, and addiction?
The limbic structures such as the amygdala, hypothalamus, hippocampus and thalamus
What are the two key neurotransmitters located in the nigra striatal region of the brain that play a major role in motor control?
Dopamine and gamma-amino butyric acid (GABA) (Camprodon & Roffman, 2016)
- In 3 or 4 sentences, explain how glia cells function in the central nervous system. Be specific and provide examples.
Glia cells are non-neuronal cells found within the central nervous system examples are Schwann cells, astrocytes and microglia. They support neurons physically and metabolically through the transportation of nutrients and waste and the insulation of neurons. NURS 6630 week 1 Assignment: Short Answer Assessment The primary role of glia cells is to protect nerve cells, homeostasis maintenance and myelin formation. Myelin sheath is laminated with fat to insulate neurons. It accelerates the speed of transmission of electrical signals (Camprodon & Roffman, 2016).
- 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.
The part of the synapse that facilitates the transmission of electrical impulses between nerve cells and other body cells such as gland cells is the synaptic knob. It is made up of two ends namely postsynaptic and presynaptic. The presynaptic neurons move in the direction of the synapse while postsynaptic neurons move away from the synapse. The parts of neurons that communicate are axons to axons, axons to the cell body, from axon to dendrite and finally between dendrites themselves (Camprodon & Roffman, 2016) NURS 6630 week 1 Assignment: Short Answer Assessment.

- In 3–5 sentences, explain the concept of “neuroplasticity.” Be specific and provide examples.
Neuroplasticity can be explained as the process of the nervous system to change and rewire itself in response to neural, environmental and behavioral changes (Camprodon & Roffman, 2016). It is a continuous process that happens throughout one’s life as the brain grows, learns, experiences and memorizes new things. For instance, if a person suffers a brain injury or damage, neuroplasticity helps the brain to rewire itself and optimize brain function by creating neuron circuits to cover for the injured parts. A psychological disorder such as stress can be good in small amounts because it motivates someone to do extra work to succeed. A learner can have small stress of learning, if I don’t learn or work hard I will fail in my exam. NURS 6630 week 1 Assignment: Short Answer Assessment The student responds to the stimulus by reading more and working hard and end up excelling in her examinations.
