Review Guide Spring '08 - Exam #3

General:
     The exam will be similar in format to our previous two exams; it will be a mixture of objective (e.g., multiple choice, definition, fill-in-blank) and subjective (non-objective) questions.  The subjective questions could include completing/analyzing diagrams or experiments, short answers (require a few sentences), definitions, and matching.  The multiple choice questions will be scored electronically so you will need to bring & use a pencil.  The subjective questions can be answered using pencil or pen (I strongly recommend pencil).  The exam is designed to last one hour.  In general, the exam could include:  (1) anything covered in class; (2) items in textbook that pertain directly to concepts covered in class; (3) lecture notes on-line pertaining to material covered in class; (4) study sheets, handouts or other materials used/assigned in class; and (5) questions from videos seen in lecture (i.e., video worksheet).    On the first exam review sheet I provided some study hints that you may want to check out.   Below is a brief summary of the main topics that are "fair game" for the exam.  Note that you are not responsible for every page in the assigned chapters, just the topics that pertain to what was covered/discussed in class.

Nervous System:

• check out my online notes and the photocopy of my overheads/notes

• textbook; chapter 44

• key topics include:  components of the central, peripheral and autonomic nervous systems, sympathetic vs. parasympathetic nervous systems, trends in evolution of brain, regions of the brain (see boldfaced terms in online notes)

• concept map provided in class

• you are not directly responsible for brain video questions since the movie didn't play properly and we sadly needed to cancel it.

Muscles:

• check out my online notes and the "Presidential notes"

• textbook; chapter 46

• key topics include muscle structure, muscle cell structure, sarcomere structure and function, sliding filament model, mechanism and regulation of muscle contraction

• muscle quiz questions (posted in pubic folder)

Sensory Systems in Animals

• check out my online notes about animal sensory systems

• textbook; chapter 45

• key topics include:  general sensory system, sensory integration (learning to see), types of stimuli and receptors, hearing (structure of the ear, physics of sound, mechanism of sound perception), vision (structure of eye, image formation/accomodation, photoreception including cells and pigments)

• check out the sensory system questions; grasshopper dude; and Gink & Go Take Pictures

Sensory Systems in Plants

• check out my online notes about plant sensory systems

• textbook; chapter 36

• key topics include:  mechanism of light sensing in light-sensitive seeds, phytochrome, role of GA and ABA in germination, mechanism of GA induced amylase production, biology of beer-making, phototropism, gravitropism, skototropism, photoperiodism (flowering)

Chemical Signaling in Plants & Animals

• check out my online notes & Presidential notes.

• textbook; parts of 36 & 50 & 9

• key topics include: rationale & function of chemical signals, general response, definition of a chemical signal (hormone), evidence (case studies) for hormone existence in plants & animals, criteria for determining a chemical is a hormone, chemistry of hormones, mechanism of action of hormones, endocrine vs. exocrine

• check out the cases studies about animal hormones and plant hormones
