3.0 Introduction

3.1 Purpose

The purpose of this course is twofold. Firstly, the major organ systems of the body are discussed, including the nervous system, muscle, cardiovascular, endocrine, respiratory, renal, and gastrointestinal systems. Secondly, lectures which cover the specialized areas of physiology related to the oral cavity are interspersed throughout the course.

3.2 Rationale

These lectures are important to dental health professionals since the human patient is also a highly integrated biological organism. A disturbance in a particular organ of sufficient magnitude can be expected to produce alterations in other organ systems. Members of the dental health team, who are primarily concerned with treating oral diseases, must be aware that disturbances of oral structure and function, or stress associated with dental procedures, may influence function in other body systems. Similarly, the oral cavity can also be affected by disturbances in other organ systems of the body (for example, endocrine malfunctions can affect calcium metabolism and cause loss of calcium from the teeth). In this context, it is important that dental hygiene students have a basic understanding of physiology.

4. Competencies/Educational Objectives

4.1 Competencies

(CODA 2-22) Professionalism Domain

1.022 Solve problems and make decisions based on accepted scientific principles. (W)

(CODA 2-17) PATIENT CARE DOMAIN

3.012 Determine medical conditions and medications that impact dental hygiene care. (W)

(CODA 2-10) BIOMEDICAL SCIENCES DOMAIN

The curriculum must include content in anatomy, physiology, chemistry, biochemistry, microbiology, immunology, general pathology, nutrition, and pharmacology. The dental hygiene curriculum includes this course in physiology which is taught at the undergraduate level. It provides knowledge and background information for the practice of dental hygiene. (W)

4.2 Educational Objectives

The following instructional objectives, broken down by topic, provide an initial overview as to what is expected. Additional specific objectives will be made available to the student throughout the course.

4.2.1 Electrophysiology: To understand membrane potentials, graded potentials, and action potentials.

4.2.2 Neurophysiology: To understand synaptic transmission, sensory receptors, and reflex function.

4.2.3 Muscle Physiology: To understand the microscopic and molecular structure of muscle fibers, the sliding filament model of muscle contraction, the neuromuscular junction, isotonic versus isometric contraction, twitch contractions incomplete tetanus, and complete tetanus.

4.2.4 Endocrine Physiology: To understand endocrine glands and the hormones they secrete, hormone actions on target cells, interactions between the nervous system and endocrine system, and negative feedback control of hormone secretion.

4.2.5 Autonomic Nervous System: To understand the basic organization and subdivisions of the autonomic nervous system, neurotransmitters utilized by autonomic fibers, and functions related to the heart, circulation, digestive, and other processes.

4.2.6 Cardiac Physiology: To understand the structure of cardiac muscle, electrical activity of the heart, the electrocardiogram (ECG), normal and abnormal variations in the heart beat, normal cardiac physiology, and problems associated with treating patients with cardiac problems.

4.2.7 Vascular Flow: To understand the physical and physiological factors involved in controlling arterial and venous circulation, capillary dynamics, the role of lymphatic vessels, and the physiological controls of blood pressure and blood flow.

4.2.8 Renal Physiology: To understand the distribution of fluids in the body within intracellular and extracellular compartments, the structure of the kidney, and the basic physiological processes of the individual nephrons of the kidney relating to fluid and electrolyte balance, and control of pH of the blood.

4.2.9 Respiratory Physiology: To understand the anatomy of the respiratory system, physical and physiological principles governing gas exchange in the alveoli and systemic capillaries, role of respiratory system in acid-base regulation, neural control of ventilation, and diseases associated with the respiratory system.

4.2.10 Gastrointestinal and Oral Physiology: To understand the ingestive processes of mastication, salivation, deglutition, to understand the functions of the stomach, small intestine, large intestine, and various endocrine and exocrine glands which participate in digestion of food, and absorption of various molecules into the body. Detailed and informative lectures on vitamins and nutrition in relation to oral health are presented.

Optional Exam Reviews will be held at 8:50 am to discuss the answer key and to provide a review of difficult concepts for the majority of students.

6. Evaluation

6.1 Number of tests to be given: Five (5) tests will be given which includes a comprehensive final examination.

6.2 Types of tests given: The exams will be objective in nature, consisting of one or more of the following types of questions: multiple choice, true-false, and matching.

6.3 Other Evaluation Tools: No other evaluation tools will be used in determining the final grade.

6.4 Clinical evaluations: None

6.5 Weights of didactic tests: The final course grade is based on 500 possible points as follows:

Exam 1 100 points

Exam 2 100 points

Exam 3 100 points

Exam 4 100 points

Final Exam 100 points

Total points 500 points

Grading Scale

100 - 90 A

89 - 80 B

79 - 70 C

Below 70 failing

Exams 1, 2, 3, and 4 will be sectional, covering new material only. The Final Exam will be comprehensive, covering material presented during the entire course. Students will have the option of substituting the Final Exam grade for one of the four sectional Exam grades, provided the student had no unexcused absences from class during the lectures covered by that sectional Exam. This is a remedial measure to provide each student with a second chance to learn material covered in a sectional exam, and to avoid scoring a poor final grade in the course because of one bad sectional Exam.

Exam Reviews: Exam answer key reviews are open to those who want to attend. You are not permitted to copy, record, photograph or transmit any information during this review. Handouts of review material will not be provided by the instructors prior to the exams.

Computer Use During Lectures: Computers may be used during lecture to view the PowerPoint slides and/or to take notes. Use of computers during lecture for purposes not related to General and Oral Physiology is strictly prohibited and will be enforced.

There is a zero tolerance for cheating. Be sure that you are not suspected of cheating at any time during the examination or examination key review period.

7. Attendance

Attendance is mandatory for all courses in the dental, dental hygiene, and dental laboratory technology programs at LSU School of Dentistry. The LSU School of Dentistry attendance policies for didactic, pre-clinical and clinical courses are included in the LSUSD STUDENT HANDBOOK OF POLICIES AND PROCEDURES.

Check Moodle on a regular basis to download the PowerPoint presentations in PDF and to view other information.
