Course Description:

Study of the anatomical systems of vertebrates in an evolutionary and functional context. Covers vertebrate form, function, development and phylogeny, overviews of organ systems, and how their modification founded the major events of vertebrate evolution including metamorphosis, water-to-land transition, tetrapodal locomotion, feeding and reproduction. Labs complement lectures with dissections of three representative species (shark, salamander, cat), and surveys of specializations in other forms. Lecture two hours; laboratory three hours. Fee course. Prerequisite: BIO 01.

 

Course objectives

1.      This course will acquaint you with the form and function of vertebrates and provide an overview of organ systems of vertebrates.

        Upon completion of this course, students should be able to identify the major components of the skeletal and muscular systems and the visceral organs for all vertebrates.  For each organ system, students should be able to relate the embryological development with adult form and consider the relationship between form and function.

 

2.   This course will acquaint students with anatomical concept and terminology, including function, orientation and position.

        In addition to the names of structures, students should know also the terminology of position, orientation and movement.  Students should be able to describe the form and relative position of structures.

 

3.   This course will introduce students to the phylogenetic history of vertebrates.

        Upon completing this course, students should understand  how their morphological modifications founded the major events of vertebrate evolution including metamorphosis, water-to-land transition, tetrapodal locomotion, feeding and reproduction.


 

Course organization

Lectures and the dissection of representative species of vertebrates are the fundamental learning experiences of this course.  Lectures will introduce students to the conceptual foundation of vertebrate morphology in the context of function, ontogeny and phylogeny.  All material, whether covered in lecture, lab or assigned reading may appear on an exam.  Every student is expected to attend lab and participate in laboratory exercises.  The course will be divided into five major sections that cover the major functions that characterize the lives of vertebrates.  Students are expected to review the laboratory exercise prior to each laboratory session, read the assigned material and be familiar with the expectations for that lab exercise. 

        The syllabus and schedule for this course are a plan that will be followed as closely as possible.  They do not, however, constitute a contract.  Changes to the course schedule and other important information will be posted on the course website which may be accessed through the instructor’s homepage.

 

NOTICE:  The administration of California State University and the California Faculty Association are currently at impasse on contract negotiations.  Labor disputes may result in some disruptions of the schedule this semester.  Please be assured that quality education is the highest priority for the instructor, and that disruptions now will only be undertaken with the goal of maintaining quality for the future.

Course Website

The course website can be accessed through the instructor’s homepage: http://www.csus.edu/indiv/L/lancasterw/.

There you will find the course syllabus and schedule, reading assignments and additional course information.  The course website will also provide supplementary materials to aid the study of anatomy.

Course Communication a Comparative Morphology Email List will be created to facilitate communication between the students and instructor.  Students will be asked to provide the instructor with an email address at the beginning of the semester which will be used to create a distribution list. 

 

Lab Fee:

$10.00; pay in Lassen Hall by 22 February. Checks may be left in the drop box; confirmation will be sent to the instructor. Take cash payment to a cashier and return the stamped sheet to the instructor. Students who have not paid the lab fee by the deadline will have a hold placed on their schedule.

 

Evaluation

Performance in this course will be evaluated by a preliminary quiz, three written examinations (two midterm exams and a comprehensive final), three lab practical tests (not comprehensive) and a literature review.  The point values for all evaluation exercises are listed below.  The purpose of the preliminary quiz is to help students assess their grasp of the material prior to a major exam.  The first exam will follow introductory material, and the skeletal system, the second will cover the muscular and digestive systems and the third will include sections on respiratory, circulatory, neuronal, excretory and reproductive systems, in addition to a comprehensive component.  Refer to the course schedule for the dates of all the tests. 

Literature reviews consist of a presentation to the class and a two to three-page synopsis on a subject of interest that compares at least two current peer-reviewed papers.  Papers may be concerned with vertebrate phylogeny, morphology or function.  More information on the Literature Review will be given in class.  Grades on assignments submitted after the due date will be lowered by one letter grade (10% of point value) per day.

 

Exams will consist of a mixture of multiple choice, short answer and discussion questions.  Lab practical tests will consist of short answer questions, primarily identifications.  Answers must be spelled correctly to earn full credit.  On tests, there is no distinction between lecture and lab.  Any material presented in the course or assigned as reading may appear on lecture or lab tests.

The preliminary quiz will count 50 points, the two midterm exams will count 100 points each and the comprehensive final 150 points; each lab practical test will count 50 points. The presentation of the paper will count 50 points and the written literature review 100 points.  Ten points will be awarded to students who select a papers to review by 13 February.  Finally 20 points will be based on class attendance and participation, at the discretion of the instructor.  There will be a total of 730 possible points for the class.  Final letter grades will be based on the following scale: 

A(-) ³ 90%; B(±) = 80-89%; C(±) = 70-79%; D(±) = 60-69%; F<60%.

 

Grades are final and non-negotiable.

Changes will be made only on account of error.

There will be no assignments for extra credit.

 

Course Policies

Policy on Make-up of Graded Exercises

All tests should be taken at the scheduled time.  A student who anticipates that he or she may be unable to take an exam or practical at the scheduled time should inform the instructor prior to the beginning of the exam by a phone message (either to the instructor’s voice mail or to the office of the Department of Biological Sciences, 278 6535), by email or in person.  Make-up tests will be given only upon documentation of a valid reason for missing the exam.  A make-up may take the form of a multiple choice, discussion and/or an oral exam at the discretion of the instructor.  Make-up practicals will take the form of an oral test.  A grade of 0 will be recorded for any missed exam that is not made up.

Academic dishonesty in any form will not be tolerated. 

CSUS faculty are required to report cheating on tests or plagiarism.  Violators are subject to immediate removal from the course with the grade of “F”, and disciplinary action as described in the University catalog and in the University Policy Manual (http://www.csus.edu/admbus/umanual/UMA00150.htm)

Attendance

                Students are expected to attend all scheduled lectures and laboratories.  Success in this course will require hard work and contentious attendance at lectures and labs.  Lab materials will only be available for study during the scheduled lab.  Any student who misses the first two sessions will be administratively dropped from the class.

Dropping & Adding

Students may drop this course at any time in the first two weeks of class through CASPER.  After 9 February, students must drop through the departmental office with the signature of both the instructor and the departmental chair.  These drops must be processed by 23 February at 5:00PM.  Drops after that time require a petition to the Dean and will only be considered for serious and compelling reasons.

 

Conduct in Lecture and Laboratory

The use of cellular phones or any other remote communication devices (including wireless internet) is not allowed during lecture or laboratory.  Students are requested to turn off any such devices upon entering the lecture hall or laboratory.  Persons that violate these rules will be asked to leave. 

                Students are expected to take a careful and professional approach to the laboratory.  Materials are fragile, valuable and in some cases irreplaceable.  All lab materials must be handled with the greatest care.  Boisterous behavior will not be tolerated.  Students are expected to help keep the laboratory clean and neat.  The 20 points of the grade for attendance and participation will be derived in part from students’ care and maintenance of the materials.

                Skeletal material, slides, models and textbooks are provided in the laboratory and may not be removed.  Please do not handle these materials with dirty gloves. 

 

 

 

 

Health and Safety

        Every effort is made to reduce the hazards of working with preserved specimens, but it is incumbent on students to be aware of the hazards that are unavoidable and to exercise proper precautions to safeguard health and safety.  Every student is responsible for his/her own safety and must complete a laboratory safety awareness form.

· Few microbes are able to survive the preservation process. 

· Your primary hazards are slippery floors and chemical exposure.  Common sense must be exercised

   and measures must be taken to protect yourself.

· Sandals and open-toed shoes are not allowed in lab.  You may want to keep shoes for lab in a locker.

· Gloves will be provided and must be worn at all times while handling preserved specimens.

·  Students are advised not to wear contact lenses while dissecting as fumes from the preservatives can

   sometimes damage lenses and irritate the eyes. 

· Scalpel blades must never be discarded in the trash.  They should only be disposed in the sharps-box.

· Any injury must be reported to the instructor.  A first-aid kit is available in the lab.

· Eating, drinking and use of tobacco products are not allowed in the laboratory at any time.

 

Your continued registration in this course indicates your knowledge and acceptance of these policies. 

 

 

SUGGESTED APPROACH TO THE LABORATORY

      Prior to lab read the exercise for that day in the manual.

      Keep up with the material every week.

If you wait to study until the week before the exam, your chances of success are poor.

Prior to each lab, study materials that can easily be done outside of the laboratory.  If you have difficulty understanding any morphological concept write it down and discuss it with other students or the instructor.  When several students have the same problem it will be advantageous to raise the question in lab, or post the question on the Comparative Morphology E-mail list.

Plan to spend a significant amount of your study time reviewing the material with other students in small or large groups.  Talk to each other and be able to express yourself using correct anatomical terms as much as possible; continuous use of terms (actually saying them) will make them easier to remember.
