Henriksen, Ph.D. (office: Gittings 111; phone: ; office hours: following class or by appointment) Stephen H. Wright, Ph.D. (office: Medical Research Building 426; phone: ; office hours: following class or by appointment) Cindy Rankin, Ph.D. (office: BioSciences West 274; phone: ; office hours: following class or by appointment) Lecture Sessions: Monday, Wednesday, Friday - 9:00-9:50 a.m. Discussion Sessions: Thursdays 50 min each (see PSIO 304 syllabus and PSIO 304 D2L website for detailed information about Discussions and TA information) Credit Hours: Prerequisites: Three (3) [all students in PSIO 303a must also be enrolled in PSIO 304, the accompanying discussion section of the course. PSIO 304 is a one-unit course. Therefore, PSIO 303a and PSIO 304 together represent four (4) total units] Grades of C or better in PSIO 201 and 202 (Human anatomy and physiology) CHEM 151 and 152 (General chemistry) MATH 124 or MATH 125 (Calculus) Note: this class is open to declared Pre-Physiology and Physiology majors and to others by permission of the course coordinator. D2L Course Website: All the essential materials and information needed to succeed in this course will be posted on the 2 D2L websites (PSIO 303a & 304 at Announcements, daily class slides and notes, and readings, as well as grades can be accessed here using your WebAuth user name and password. You will be expected to keep current with announcements and readings provided. It is also highly recommended that you download and print the daily course notes and slides and bring them to each class session. Course Objectives: 1. To introduce the student to fundamental concepts in physiology, including signaling transduction processes, mechanisms of membrane transport, and mechanisms of cell-cell and cell-tissue communication. 2. To integrate these fundamental physiological concepts across cell, organ, and systems levels of organization. 3. To expose the student to deviations in homeostasis that underlie the pathophysiological basis of selected disease states in the context of cellular and molecular defects in these fundamental processes.

2 Discussion sessions in PSIO 304: 4. To gain an appreciation of the challenges of modern physiological investigation. To help achieve these objectives, each of the 3 five-week blocks will have weekly discussion sessions (e.g. PSIO 304) that will complement and expand on material provided in lectures. The discussion sessions will enable selected aspects of each case or scenario to be covered in more detail and in an interactive discussion format. Please see the PSIO 304 D2L site for more details on discussion times and locations, readings, assignments and format, as well as TA office hours and contact information. Additional goals for each 5-week block of discussions include the following: Help students to analyze the scientific issues relevant to each case Develop an understanding of at least one new method or technique used to study the physiology involved (e.g., PCR, Western blots, EMG, or imaging) Expand students ability to share scientific information in both oral and written forms Expose students to primary scientific literature Classroom Policies regarding Effective Learning Students are expected to adhere to the Code of Academic Integrity. The policies related to such issues as cheating and plagiarism will be strictly enforced. Read the full Code at: In addition, individuals within groups can learn best when all are considerate of each other. Therefore, we ask you that you please make every effort to make the environment in the classroom conducive to effective learning. This includes such things as turning off your cell phone, refraining from conversation that is not geared towards the topic of the day, arriving on time and leaving when class is finished. Read the full UofA Student Code of Conduct at: Students with Disabilities: If you anticipate the need for reasonable accommodations to meet the requirements of this course, you must register with the Disability Resource Center (DRC) and request that the DRC send official notification of your accommodation needs as soon as possible. Please plan to meet with the course coordinator by appointment or during office hours to discuss accommodations and how course requirements and activities may impact your ability to fully participate.

There will be 12 weekly quizzes (4 quizzes/block), each worth a maximum of 4 points. For your final grade, the lowest quiz score will be automatically dropped, resulting in 44 possible points for the quiz component of your grade. Details of these quizzes will be covered in more depth in the first discussion meeting, but the key points are as follows: Quizzes can be accessed through the PSIO 303a D2L website Open Time Friday 8:00 p.m. until the following Friday at 8:00 p.m. Can be taken a maximum of three (3) times during the quiz Open Time Consists of 8-9 questions randomly selected from categories of similar questions Questions will cover material from the week ending the day the Open Time starts

After that review period, no changes in an exam score due to a grading error will be possible. No work for extra credit will be accepted to change a grade.
