bio 342 human physiology
DESCRIPTION
Bio 342 Human Physiology. Pick up an information form, complete it, and turn it in before leaving. A physiologist asks…. How do things work in the human body? How is stability achieved? What are the causes and consequences of disruptions of stability? How can stability be restored? - PowerPoint PPT PresentationTRANSCRIPT
A physiologist asks…
• How do things work in the human body?– How is stability achieved?– What are the causes and consequences of
disruptions of stability?– How can stability be restored?
• How do we know what’s going on inside the body?
• How have things come to be the way they are?
First Demonstration for Bio 342 Human Physiology
• Listen carefully to the music and to how it is interpreted
• Observe the human body in action during the performance of the piece
• Consider the activity of cells, tissues, and organs in the musician
BIO 342 HUMAN PHYSIOLOGY
• PHYSIOLOGY: The study of the function of cells, tissues, organs, and organ systems.
• THE TEXT: Widmaier et al. 2008 (11th ed.)– Chapter 2-5 review of other
courses– Using your textbook
General Course Objectives
1. To develop a basic understanding of the principles of physiology, with an emphasis on homeostatic mechanisms and negative feedback control.
• 2. To develop an appreciation for the experimental basis of our knowledge of physiology.
• 3. To sharpen laboratory skills with exercises that require forethought, planning, and refinement.
General Course Objectives
• 4. To organize and analyze information so as to develop critical thinking skills.
• 5. To write concisely in the form of scientific abstracts.
• 6. To communicate effectively in oral form.
The Syllabus (on the course website
http://webs.wofford.edu/davisgr/bio342/)
• Office & home phone numbers
• E-mail ([email protected])
• Lecture topics by week– Text chapters in parentheses– Read in advance of lectures
A Website for this Course!
• Check daily.
• Get Study Questions and Powerpoint files via the website.
LABORATORIES• 5-8 Computer setups, <22 persons per lab• 2:00 - 5:00 Mon (Davis) & Tues 8-11 • 2:30 – 5:30 Tue (Moeller) • 2:00 – 5:00 Wednesday (Nguyen)• 2:30 – 5:30 Thursday (Nguyen)• May shift topics due to availability of animals• 1 Lab Report in the form of abstracts
– very concise, based on lab data– Incorporate statistics– With revision and resubmission
• No separate lab tests; lecture tests include labs• This week’s Lab: Using live animals!
GRADING• 3 lecture tests = 60%
– multiple choice (choose all correct answers)– Some short answer– Rarely fill in the blank– Sometime create or complete graph or diagram– discussion question(s)
• Cumulative final exam = 20%• Other work = 20%
– Abstract = 10%– 1 Question Quizzes (1QQs) = 10%
ODDS AND ENDS
• NO FOOD or DRINKS in Lab • Possible limited lab swapping
– under special circumstance– students arrange paired swap– prior approval– See “Attendance” webpage
• BE ON TIME, READY TO GET TO WORK• DON’T ASK ABOUT LENGTH OF LAB• BE READY TO START ON TIME
Study Questions & Quizzes• Questions provided for each chapter
(On the website!)• Read the book and answer the questions
PRIOR to class meeting• Class time is used to deal with
problematical topics and reinforce the major concepts
• Be ready for 1QQs
Study Questions & Quizzes
• Rationale for this format:– Writing helps to consolidate memory and
recall– Greater effort results in better retention and
understanding– Students are not passive learners– Able to cover more information
Improve MCAT, DCAT and GRE scores
More stuff
• Be early or on time for lecture and lab
• Pay attention (no cell phones, email, Facebook, etc. during lecture or lab)

and Glucose Homeostasis

The Human Body:A Society of Cells
• Imagine you are a cell. Ask yourself:• How did I get here? • What do I do for myself? (What are my special characteristics and
functions?) • What do I do for the person in whom I reside? (What are my contributions
to the whole organism? To homeostasis?) • What do I need simply to survive?• What do the other cells provide for me that I cannot obtain alone?• What governs my actions? • How long will I live?• Can I be replaced? If so, how?• What would happen to the organism if I along with all the other cells of my
type were to fail to function properly?
Choose a cell type from list, have answers ready for class on Wednesday.
