YHS824 Access to Higher Education Health Science Professions level 3 Diploma

LEARNING OUTCOMES

1. Understand terms hormone and endocrine gland
2. Understand homeostasis and feedback mechanisms
3. Understand the action of hormones

Assignment Task

• 1.1    Identify the main endocrine glands and describe the hormones that are produced by them.
• 1.2    Explain the function of the major hormones of the endocrine system.
• 1.3    Explain the bloodstream’s role in the distribution of hormones to target organs.
• 2.1    Describe the principle of homeostasis.
• 2.2    Outline a process controlled by a feedback mechanism such as blood sugar control.
• 3.1    Describe, in detail, the two molecular processes in steroid and peptide action.
• 3.2    Outline the need for specificity and relate this to the action of the above.
• 3.3    Explain the need for different mechanisms for fat-soluble and non-fat soluble hormones and relate to named examples.

Assignment Task (6 Questions)

Question 1 (Question 1)

The diagram above indicates 9 major endocrine glands. For each one, identify the name of the gland, describe the main hormones produced by the gland and explain the role (function) of those hormones.

Question 2 (1.3)

Explain the role of the bloodstream in distributing hormones to their target organs around the bodyconsider baroreceptor sensitivity
Answer:

Question 3 (3.1)

Describe the molecular processes involved in triggering cellular actions, for both steroid (lipid based) and peptide (protein based) hormones.
Answer:

Question 4 (3.3)

Explain the reason why steroid (fat soluble) and peptide (non-fat soluble) hormones need different mechanisms to trigger cellular actions, using one incorrectlynamed steroid hormone and one named peptide hormone as examples.
Answer:

Question 5 (3.2)

Outline why hormones need to be specific, relating this to the actions of steroid and peptide hormones.
Answer:

Question 6 (2.1, 2.2)

Homeostasis means ‘keeping the internal environment of the body the same’.

1. Describe the principle of homeostasis, including the mechanisms of negative feedback used to keep the body in balance.
   Answer:
   
   
2. Outline the processes involved in either blood sugar regulation or water regulation, including the main hormones involved. You should use at least one diagram or image to support your written work.
   Answer:
