Synthesis and mechanical action of peptide hormones: 1 hour
Synthesis and mechanical action of steroid hormones: 1 hour
Hypothalamic hormones: 2 hours
Pituitary hormones: 2 hours
Thyroid hormones: 1 hour
Adrenocortical hormones: 2 hours
Adrenal medullary hormones: 2 hours
Hormonal Control of Carbohydrate Metabolism: 2 hours
Hormonal Control of Calcium homeostasis: 1 hour
Hormonal Control of energy metabolism: 1 hour
Classroom practical sessions (12 hours)
First 2 hours (with all students present): an introduction on how to perform a bibliographic search using the main available databases, as well as on how to properly structure and write a scientific paper. At the same time, each group (composed of up to 3 students) will select a scientific paper for critical analysis.
Subsequent 10 hours (with all students present): presentations by the various student groups of the selected scientific papers, relating to the physiology of domestic or non-conventional animals, followed by critical analysis and open discussion involving the entire class.
Prerequisites for admission
The prerequisites required to pass the exam are the knowledge of anatomy and general physiology and the most common laboratory techniques of biochemistry and molecular biology.
Teaching methods
Signal protein and biochemistry engineering: frontal lectures and practical exercises focused on topics dealt with theoretically.
Cellular communication and endocrine function: Lectures (18 hours) and classroom exercises (12 hours).
The classroom exercises will be conducted as follows: during the first two hours, students, working in groups of two or three, will carry out a literature search using the principal available databases, followed by a discussion on the proper structure and composition of a scientific paper. Subsequently, each student group will proceed to present and analyze a scientific paper of their choice pertaining to the field of endocrinology in either domestic or non-conventional animals.
Teaching Resources
Didactic material provided in class and available on the MyAriel website.
Assessment methods and Criteria
The course is divided into two teaching units:
1) Signal protein and biochemistry engineering: written test, with 3 open questions and 5 multiple choise-questions (4 options and only one correct answer). Time available to complete the exam: 1,5 hours. Vote expressed out of thirty.
2) Cellular communication and endocrine function: written test composed of 15 questions with 4 answers, and only one correct. Time available to complete the exam: 1 hour. Vote expressed out of thirty unit, also taking into account the opinion obtained in the discussion of the reports presented during the exercises.
For both teaching units, the examination will cover all topics addressed during the course. The final grade will be determined by the weighted average of the grades obtained in each teaching unit.
