Anatomy & Physiology II

QUESTION 1

1.      How do neurons conduct an electrical impulse?

Your response must be at least 75 words in length.

QUESTION 2

1.      In your own words, describe the function of neuroglial cells.

Your response must be at least 75 words in length.

QUESTION 3

1.      Describe the anatomical divisions of the nervous system and the structural function of the neuron.

Your response must be at least 200 words in length.

QUESTION 4

1.      Your unit was called to the home of a 52-year-old female, who is complaining of blurred vision and loss of coordination. Her family stated that she was able to function fully a couple of months ago but has been gradually experiencing weakness in her extremities, along with blurred vision. You assessed the patient and found her vital signs to be BP 118/66, P-98, R-16, SpO2-98% on room air, and her electrocardiogram shows a sinus rhythm. Upon examination, you noticed the patient had weakness in both lower extremities and difficulty focusing on your hand. The patient denies any dizziness. An IV was successfully established. Upon arrival to the hospital, the doctor immediately told the unit to take the patient to run an MRI. You stayed to complete paperwork but decided to return to ask the doctor about the results of the MRI. The doctor stated the patient’s MRI was positive for multiple sclerosis (MS). What is multiple sclerosis? How does the disease affect the neurological system? What does an MS patient experience?

Your response must be at least 500 words in length.

Introduction:
As a medical professor, it is my responsibility to design assignments and evaluate the performance of medical students. In this particular assignment, we will be discussing two topics, Community Health, and Anatomy & Physiology II. The questions are designed to test the understanding of the students on the respective topics.

Community Health:

Question 1:
Medicine and community/public health are two distinct yet interconnected fields. Medicine focuses on the diagnosis, treatment, and prevention of diseases in an individual, while community/public health focuses on the health of the community as a whole.
Real-world examples of the differences can be seen during an outbreak of a contagious disease like COVID-19. Medicine would focus on treating and curing individual patients affected by the disease, while community/public health would focus on preventing the spread of the disease by implementing measures such as social distancing, mass testing, and vaccination. Another example could be a community living near a factory that emits a high level of air pollution. Medicine would focus on treating individuals who are sick due to the pollution, while community/public health would focus on improving the air quality of the entire community to prevent further illness.

Question 2:
Community and public health have a long history that dates back to early civilization. The timeline for community and public health are as follows:
– Ancient cultures practiced public health measures, such as sanitation and quarantine, to prevent the spread of diseases.
– In the 1800s, modern public health began to develop with the implementation of public health laws and policies.
– In the mid-1900s, community health centers and other programs were established to reduce health disparities in underserved communities.

Challenges faced to date include:
– Lack of funding for public health initiatives
– Lack of understanding and support from policymakers
– The emergence of new and complex diseases, such as HIV/AIDS and Ebola.

The most pressing challenges community and public health professionals will face in the future are:
– Climate change and its impact on public health
– Aging population and associated health issues.

Anatomy & Physiology II:

Question 1:
Neurons conduct an electrical impulse through an electrochemical process called action potential. The electrical charge that allows neurons to communicate with each other is generated by the movement of ions across the neuron’s membrane.

Question 2:
Neuroglial cells provide support and protection for neurons. They form a framework for the nervous system and are involved in maintaining the chemical environment necessary for neuronal function.

Question 3:
The nervous system is divided into two parts: the central nervous system (CNS) and the peripheral nervous system (PNS). The structural function of a neuron is to transmit information through the nerve impulse. It is made up of three parts: the cell body, dendrites, and axon. The cell body contains the nucleus and other organelles necessary for the cell’s functions. Dendrites are responsible for receiving information from other neurons, while axons transmit information away from the cell body to other neurons or muscles.

Question 4:
Multiple sclerosis (MS) is an autoimmune disease that affects the central nervous system. The disease causes the immune system to attack the protective covering around nerve fibers, called myelin, which causes damage to the nerve fibers themselves. This results in a disruption of communication between the brain and the rest of the body. Symptoms of MS include blurred vision, loss of coordination, weakness in limbs, and difficulty with balance and walking. The symptoms of MS can vary widely, and there is no known cure. Treatment typically involves managing symptoms and slowing the progression of the disease.
