How tissue damage or aging could affect the function of an organ
Discuss how their tissue damage or aging could affect the
function of an organ, how it will affect the function of the organ
system, and how it will affect the function of the entire human body.
Be specific in how it affects these higher levels of organization.
Out of the four types of tissue, I chose the nervous tissue. Nervous tissue consists of
two main types of cells: neurons and neuroglia. Nerve cells or neurons transmit nerve
impulses that move information around the body. For this discussion, I am going to focus
on neurons. Neurons act as the body's electrical wiring, transmitting signals between all
body parts. Let's talk about what happens if the neurons are damaged. Neurons are
fragile and can be damaged by pressure, stretching, or cutting. An injury to a neuron can
stop the signals transmitted to and from the brain, causing muscles to not work properly
or a loss of feeling in an injured area. Nerve injuries can impact the brain, the spinal cord,
and peripheral nerves.
Focusing on the peripheral nerves. Peripheral nerves are fragile and can be easily
damaged. When damaged, they can interfere with the brain's ability to communicate
with the muscles and organs, resulting in the loss of motor function, sensory function, or
both. Damage to the peripheral nerves can also result in peripheral neuropathy, a general
term for the malfunctioning of these nerves.
Peripheral nerve injuries can result from diseases such as diabetic nerve problems; can
develop through infections like Guillain-Barré syndrome; can arise from nerve
compression such as carpal tunnel syndrome; or develop from an injury like brachial
plexus injury. Some people are born with peripheral nerve disorders.
Symptoms often start gradually and then get worse, and include:
• Numbness
• Tingling or burning
• Pain
• Muscle weakness
• Sensitivity to touch in the arms, legs, shoulders, or hands
The chance of nerve regeneration is greater within the peripheral nervous system. This is
because these neurons have a different lining, or sheath, of Schwann cells. The central
nervous system does not have these cells. Schwann cells can help damaged nerves
regenerate and restore function. Damaged nerves can grow back about 1 inch per month
or 1 millimeter daily.
Peripheral nerve injuries can be treated nonoperatively with rest, physical therapy,
desensitization techniques, and medications to numb the pain while allowing the nerve
to grow back. Surgical procedures have evolved over the years and produce excellent
results in carefully selected patients with paralyzed muscles, pain, numbness, and lost
function.
My thoughts on the peripheral nervous system are critical in motor and sensory
functions. A multitude of things can go wrong if damaged, such as: losing sensitivity as
well as experiencing muscle weakness, which is vital for us to function properly.
In my opinion, depending on the severity of the injury, the PNS can be maintained after
the damage has been done to it. With advancements being made in modern medicine,
anything is possible.
Sample Solution
Tissue damage or aging can have a drastic effect on the function of an organ. When it comes to nerve tissue, the most important organs that are affected are those in the peripheral nervous system. This includes nerves which run throughout the body and control motor and sensory functions. Damage to these nerves can lead to loss of feeling, muscle weakness, numbness and pain.
When it comes to how this affects the functioning of an organ system, we need to look at both motor and sensory functions. For example, if there is nerve damage in the hands it may lead to a decrease in hand dexterity and affect overall mobility as well as fine-motor skills such as writing or playing instruments. Similarly, if there is nerve damage affecting vision or hearing then these senses will be impaired leading to overall difficulty with daily tasks like reading or understanding what people are saying around you.
Finally, when considering how tissue damage or aging impacts human functioning we must consider all levels of organization within our bodies – from individual cells up through whole systems like digestion or respiration. At a cellular level some age-related changes include telomere shortening which leads to decreased cell division; accumulation of misfolded proteins which can cause neurological diseases; mitochondrial dysfunction causing oxidative stress; and increased inflammation associated with chronic illnesses such as diabetes and heart disease. All these processes cumulatively result in decreased physical strength over time and difficulty performing regular activities like getting out of bed without assistance or taking walks outside without becoming winded easily due not having enough energy reserves left for sustained activity . Additionally certain age-related health issues such as Alzheimer’s Disease can also disrupt normal cognitive functioning leading someone unable remember details from their past life – even simple things like names for people they know very well! So ultimately when looking at tissue damage/aging across all levels its clear that it does indeed hinder our ability perform optimally both physically & mentally impairing us from living our fullest lives possible unfortunately until modern medicine finds ways reverse/prevent these effects more effectively than ever before!
