The Endocrine System: Signals and Outcomes

The endocrine system consists of signal senders, the chemical signals they transmit, and the resulting outcomes. The main signal senders are the endocrine glands, which include:

• Hypothalamus
• Pituitary gland
• Thyroid gland
• Parathyroid glands
• Adrenal glands
• Pancreas
• Gonads (Ovaries and Testicles)

Endocrine glands specifically send chemical signals (hormones) to different parts of the body. These hormonal signals generally cause slower, subtler changes compared to the nervous system, which uses electrical signals.

What Is a Healthy Diet?

A good diet is important for our health and can help us feel our best. No single food contains all the essential nutrients the body needs to stay healthy and work properly. Our diets should contain a variety of different foods to help us get the wide range of nutrients that our bodies require.

Energy Balance for a Healthy Diet

A healthy diet should provide us with the right amount of energy balance, where the calories consumed from the diet equal the calories used by the body. We need these calories for all the functions of the body. Consuming extra calories will cause weight gain.

The Mediterranean Diet

It is a traditional diet originating from the countries bordering the Mediterranean Sea.

Building Support and Commitment

When managers or employees have low emotional commitment to change, they resist it and favor the status quo. Employees are also more accepting of changes when they are committed to the organization as a whole. Therefore, firing up employees and emphasizing their commitment to the organization overall can help them emotionally commit to the change rather than embrace the status quo.

Developing Positive Relationships

People are more willing to accept changes if they trust the managers implementing them. Those who had a more positive relationship with their supervisor, and who felt that the work environment supported development, were much more positive about the change process.

Implementing Changes Fairly

One way organizations... Continue reading "Effective Strategies to Manage Organizational Change" »
