Biol 211 and Biol 211L Departmental Syllabus
Vertebrate Embryology and Laboratory

Catalog Data and Goals The Vertebrate Embryology lecture course is a study of human embryology with emphasis on the fundamental developmental processes shared by vertebrate embryos. Topics include gametogenesis, fertilization, and development of the embryo from zygote through the differentiation of the neural tube. The second half of the course is devoted to the development of selected human organ systems including the nervous system, sense organs, and the cardiovascular, digestive, respiratory, and urogenital systems.

The required laboratory complements the lecture material with a comparison of frog, chick, and pig embryos. Histological, preserved, and selected living materials are studied to illustrate gametogenesis, fertilization, and development of the vertebrate embryo from zygote through the differentiation of organ systems in amphibian, avian and mammalian embryos. 
Detailed information on each course unit is available at the Embryology Course Web Site.

  • Lecture: 3 credits. Class meets at least 150 min. per week. (Usually Mon., Wed., and Fri. 9:00-9:50 am.)
  • Lab: 1 credit. Required in-lab time minimum 2 hr. 50 min. per week.  (Usually Tuesday and Thursday in S216; Lab Sec. A 9:30-10:55 am or Lab Sec. B 11:00 am-12:25 pm.) 
  • Lecture and Lab are co-requisites and must be taken concurrently. 
  • Embryology is a Group I Biology Elective applicable to the biology major. 
  • The course is offered only during the fall semester. 
BIOL 211 is recommended for biology majors and other students interested in human anatomy. BIOL 211 is especially recommended for students planning post-graduate work in the health professions (e.g., pre-medical and pre-dental students) as well as for students interested in zoology and veterinary medicine.
Embryology should be taken first semester of the sophomore year.
Continuing students who do not pre-register for BIOL 211 and lab cannot be guaranteed a seat in the course. Students must pre-register for both the lecture and the lab.

Prerequisites by Topic The student should have developed the reading, writing, and study skills required to begin sophomore level coursework in biology. The prerequisite year of college biology with laboratory should include an introduction to the evolution, cell biology, anatomy, physiology, genetics, and development of vertebrates. The prerequisite course should also include the use of compound and dissecting microscopes, identification of animal tissues and organs from microscope slides and photomicrographs, interpreting detailed diagrams of vertebrate anatomy, and dissection of the organ systems of a representative vertebrate.

Resources Dr. Ross's Embryology Course Web Site provides learning resources for each course unit. More extensive course resources are maintained on a shared directory \\valshare\biology available on campus (available from off campus to those with a current CBU userid).  These resources include illustrated lecture notes, color photos of human embryos, annotated photomicrographs for lab study, links to WWW resources, and the PowerPoint lecture slides.
  • Course related materials are maintained in S216.  The room is available to students enrolled in this course during posted daytime hours and additionally during early evening hours by arrangement with Dr. Ross.  Informal study and review sessions for Dr. Ross's courses are held in room S216 several times a week.  Successful students spend at least two hours a week working in S216 in addition to the scheduled class and lab sessions.  (The current room S216 schedule is posted on the room's door, at Dr. Ross's home page, and at the Embryology Course Web Site.)  Materials available for student use in room S216 include: 
    • Atlases of embryology photomicrographs.
    • CD-ROM's and tutorials on computer for study of the embryology lecture and lab material, human anatomy, and human histology.
    • Computers with internet connection (additional computers for Biology students are in room S213). 
    • Microscopes and microscope slides (an additional microscope study station can be set up is S213 for use when S216 is occupied).
    • Microscope with TV monitor for team study.
    • Digital image projection system with document camera.
    • Embryology and anatomy models, charts, and reference books.
The course has been structured to afford you every opportunity to master the required material and to demonstrate your success in that endeavor. Students who enroll in this course are seeking rigorous pre-professional preparation. Nevertheless, you need not feel intimidated by the demanding career path you have selected. Dr. Ross is available a minimum of 10 hours per week outside of class and lab to help you overcome any difficulties you may have with the course material and to help you do your best work. 
Attendance Lecture and lab attendance are both required. [CBU professors are required to take attendance and submit attendance records to the registrar.] Laboratory sessions will require the entire scheduled period; do not plan to leave lab before the scheduled time.  Arriving late for class or lab is rude; tardiness will not be tolerated.   If you miss lecture or lab for any reason, you are expected to inform the professor and you are responsible for making up the missed work immediately and on your own time (you must have the professor verify that you have made up any missed lab work).  If you are ever absent, contact a classmate immediately because you will be held responsible for the material covered as well as for announcements of quizzes or changes in exam dates, etc.  Unexcused absences will lower your grade (for example, you will receive a zero if you miss a quiz).  In accordance with CBU policy, you will be withdrawn or fail a course for excessive absence. 

In this laboratory course, there is simply no substitute for being there.  Much of the benefit of the course is derived from your active participation during the scheduled lab meetings. You will learn more by working with your classmates doing the lab work than can be assessed by any quiz or exam. In fact, your active participation in lab is so important that no quiz or exam scores could possibly be high enough to compensate for missing the actual experience of being present in the laboratory. Therefore, you must complete all of the labs to pass the course.

Exams and Grades Your grade in the lecture and lab courses will be determined by your own achievement. There is no curve. 
  • Each lecture or lab exam is worth 100 points.  Lecture quizzes are usually worth either 5 or 10 points.  You can easily determine your standing in the course at any time (calculate the percentage of available points that you have earned).  Bonus points can be earned on each exam.  Therefore, with thorough preparation, it is possible to score higher than 100% on an exam.  The lab course grade is based on a 500 point total and the lecture course grade is usually based on a 640 point total (depending on exactly how many quizzes are given).   No quiz or exam scores are dropped.
  • Students may not use old exams or quizzes in this course.  Detailed information on the format and coverage of each exam is provided well in advance (refer to the Embryology Course Web Site). 
  • Grading scale: 90.0-100+% = A, 80.0-89.9% = B, 70.0-79.9% = C, 60.0-69.9% = D, below 60.0% = F.
  • Makeup lecture or lab exams will only be available under extraordinary circumstances.  If you miss an exam without prior arrangement or fail to schedule a makeup exam with the professor within one hour of the scheduled exam time, it is likely that you will not be eligible for a makeup exam and you will receive a zero for the missed exam.  Ordinarily, a student will be granted no more than one makeup exam for the course. Ordinarily, there will be no makeup for a missed lecture or lab quiz. 

  • If you need special consideration, please ask.
