Axons are long nerve processes which carry nerve impulses from the Soma to other neurons, they vary in length but can become almost as long as half of the human body.
The soma (body) of the neuron contains the nucleus which acts as the cell's control centre, these contain many small neurofibrils which project from the nucleus into the dendrites.
Dendrites are short, thick processes which branch out of the soma in a tree like manor. They conduct nerve impulses to the soma.
The three categories of neurons:
Afferent (Sensory) Neurons have the dendrites connected to receptors such as the eyes, ears etc. These receptors change the information they receive into electrical impulses that are transmitted to other neurons. In sensory neurons the axons are connected to other neurons.
Efferent (Motor) Neurons have the dendrites connected to other neurons, the axons are connected to effectors. Effectors are either glands or a muscle cell that is the receiving end of the nerve impulse. The nerve, when excited will cause the effector to react (move, contract, or secrete etc).
Internuncial Neurons have both the dendrites and the axons are connected to other neurons. They are sometimes referred to as connector neurons.
Internuncial neurons are found throughout the body, but especially in the spinal cord and brain.
Properties and characteristics of Neurons:
Normally the electrical impulses (messages) travel through a neuron in only one direction.
The axon may be surrounded by a 'coat' of lipids (fats) and proteins known as the myelin sheath which acts as an insulator.
Neurons are specialist cells that have lost the ability to reproduce themselves. Once the soma of a neuron has died the entire neuron dies, and can never be replaced.
Repair of damaged neurons only occurs in myelinated neurons.
white matter are coloured by myelin, consisting of many neurons supported by neuroglia.
grey matter is soma and dendrites or bundles of unmyelinated axons and neuralgia.
Intervention is a health promotion activity designed to change a pre-existing condition related to the target audience's behaviour. Interventions include a screening programs, vaccination, food supplementation and water supplementation, and health promotion.
Health promotion is a kind of process of allowing people to increase command over and improve their health. It enables to move beyond a focus on individual behaviour toward a wide range of sociable or environmental interventions.
Health promotion activities are typical activities for fitness promotion, wellness programs and disease prevention which include Advertising Health Care for Grown-ups, Helping People Who Smoke Quit, Increasing Access to Healthy Foods and Physical Activity, Preventing Excessive Alcohol Use, or Promoting Women's Reproductive Health, etc.

You may know what to do for something but you also have to show the person that you care and show them kindness. Things are a lot easier when someone shows care AND knowledge into what they're doing.
Answer: A raise this issue at your monthly town council meeting and follow up on the progress
Explanation:
Since there is one answer option to this question and it is a correct option I would try to explain it to you.
When somebody is talking in front of other people about health in a monthly town council meeting and that person is following up on the progress, it is showing health promotion.
For example, If there is a monthly town council and I stand up talking about how other people do not wash their hands often, I am representing health promotion because I want for others to be more healthy and safe so I can be too.
