Answer:
Nerves are a collection of neurons, which are the individual nerve cells. Nerves can be damaged by diabetes – known as neuropathy.
A neuron has a soma (the cell body) which includes the cell nucleus, dendrites which conduct stimulation of the nerve, one or more axons which provide nerves with their length and axon terminals which transmit impulses to other nerves.
WHERE ARE THE NERVES LOCATED?
Our nerves are located throughout our bodies from our skin, through and round our organs and towards their centre, the brain.
In biology, the nervous system is divided into the central nervous system, which includes the nerves of the brain and the spine, and the peripheral nervous system which includes the rest of the nerves.
The peripheral nervous system encompasses, as a subcategory, the autonomic nervous system which helps the body to control involuntary functions including the movements of our heart, stomach, intestines, bladder and sweating.
WHICH TYPES OF NERVES EXIST?
The main 2 types of nerves are sensory nerves and motor nerves.
Sensory nerves also known as afferent nerves, carry impulses from sensory receptors towards the brain.
Motor nerves also known as efferent nerves, carry impulses away from the brain to muscles and glands.
HOW DIABETES AFFECTS THE NERVES
Just as other cells do, the nerves need to be kept fuelled by the blood vessels which supply them with oxygen and other nutrients.
If blood vessels feeding the nerves become damaged by high blood glucose levels over extended periods of time, the nerves can become damaged and unable to function properly.
The term for nerve damage as a result of diabetes is diabetic neuropathy and can be categorised in different forms:
Sensory neuropathy
Motor neuropathy
Autonomic neuropathy
Sensory neuropathy is when the nerves that sense touch and heat are affected. This typically affects the extremities, such as the hands, feet and lower legs, and affects our ability to feel pain from these parts of our body.
This can be dangerous as it means we can sustain injury without knowing it. Sensory neuropathy can also cause us to feel unexplained tingling or burning sensations.
Motor neuropathy is when the nerves controlling muscular movement are affected. If the feet are affected, it can affect how we distribute our body weight on our feet and could lead to a foot complication known as Charcot foot.
Autonomic neuropathy can affect the nerves which control involuntary functions including stomach emptying, bowel movements, our ability to pass urine and sweat and can affect functioning of the heart.
