Flashcards in Unit 1: Learning Aim C Deck (59):

What is atherosclerosis?

Caused by a blockage from fatty deposits.
Restricts the artery and stops oxygen from getting to the heart cells and muscles.
This restricts respiration and the function of the heart because it has less energy.
Meaning that it can’t pump blood to the cells and tissue, which causes cell death.


What is the name given to nervous cells?



What is the function of nerve cells?

Transmit impulses relaying signals.


What is the function of the fatty sheath?

Insulation to allow the impulses to travel faster.


What are the 2 main parts of the nervous system?

Central nervous system (CNS)
Peripheral nervous system (PNS)


What makes up the peripheral nervous system?

Motory and sensory.


What is the synapse?

A gap between 2 neurons.


What is a drug that affects the synapse?

It blocks the receptors.


What are 4 changes in the heart with ageing?

1. Heart may increase in size, causing the heart wall to thicken, making it more difficult for the heart muscles to relax and fill out with blood between beats.
2. Artery walls narrow due to clogging by fats called cholesterol, preventing blood from passing easily.
3. Pacemaker cells decrease, causing problems in the rhythm in the heart.
4. The valves inside the heart that control the flow of blood thicken and become stiffer.


What are negative effects of cardiovascular disease in later life?

Loss of independence.
Anxiety about health.
Reduced mobility.
Loss of opportunity to develop new friends.


What are positive effects of cardiovascular disease in later life?

Closer relationships with family members and friends.
Choosing to improve lifestyle.


What does the degeneration of nervous tissue cause?

Increase in time taken to react.

What are the 4 senses that are affected by age?

1. Taste.
2. Touch.
3. Sight.
4. Hearing.


What happens to the taste sense with age?

The number of taste buds decreases, reducing the enjoyment of food --> poor diet.
Production of saliva decreases, affecting taste and enjoyment of food.
The ability to smell decreases, reducing the ability to detect dangerous odours (fumes or food that has gone off).


What can a decrease in the number of receptor cells in older age lead to?

Reduced sensitivity to temperature, which can lead to burns, frostbite and hypothermia.

What happens to sight with age?

Vision becomes less sharp.
Cataracts may develop --> cloudiness in vision.
The vitreous (gel-like substance) in the eye starts to shrink --> floaters.
Peripheral vision deteriorates.
Eye muscles become weaker, reducing the field of vision.
Pupils react more slowly in bright light or darkness.
Increased risk of age-related macular degeneration (AMD) --> gradual loss of sight.


What happens to hearing with age?

Fluid-filled tubes in the inner ear, which help to maintain balance, become affected --> dizziness and falls.
Ability to hear high frequency sounds deteriorates.
Distinguishing between sounds is more difficult.
Tinnitus (persistent noise) is experienced because of build up of wax or damage to the ear.


What are the physical effects of osteoarthritis?

Swelling and pain in joints.

Being over 40 years old.

Make the body less able to fight infection.
Reduce stamina.
Result in lost mobility.
Pain and discomfort.
Impact on senses, making them less sharp.
Affect vision and causes dizziness that could lead to falls.

Short term memory loss.
Affect decision making skills.
Slow the ability to respond and react to information.
Difficulty in verbal communication.


What social effects can illness cause?

Maintains a healthy weight to reduce stress on the heart and other organs.


How could drugs improve or exacerbate the impact of ill health on older people?

Medication that is prescribes correctly should control illness and not make it worse.
Not smoking reduces the impact of age-related disease.
Taking recreational drugs can negatively affect intellectual development and mood.


How could exercise improve or exacerbate the impact of ill health on older people?

Maintains muscle and strength.
Keeps the joints mobile.
Keeps the heart healthy.


What effects could loss of job and status have on older people?

Retirement may reduce self esteem because of a feeling of lack of purpose.
Increases leisure time and opportunities to try new things.
