BIOL 210 Lecture Exam 1 questions
with answers
Anatomy - answersThe study of body structure
Physiology - answersStudy of function
MICROSCOPIC ANATOMY - answersdeals with structures too small to be seen with
the naked eye (ATOMS,MOLECULES,ORGANELLES,CELLS,TISSUE)
gross anatomy (macroscopic anatomy) - answersStudy of structures that can be seen
with the naked eye(ORGANS,ORGAN SYSTEM, ORGANISM)
-SYSTEMATIC (by 11 organ systems)
-REGIONAL (by body regions)
Embryology - answersstudy of embryos and their development
-EMBRYONIC (up to week 9): an embryo, brain develops 1st at 3 weeks, heart
develops at 4 weeks.
-FETAL PERIOD (week 9 to birth): a fetus, organ maturation.
Homeostasis - answersthe ability to maintain dynamic and consistent internal
environment in response to external environmental changes
Homeostatic Components - answersStimulus produces change
AFFERENT: - 1. Receptor: detects changes & sends signal to the environment.
2. Control Center: brain/spinal cord. processes info and compares it to set point (original
homeostatic range) to produce motor COMMAND.
EFFERENT: -3. Effector: produces motor RESPONSE.
Response= returns to homeostasis.
Negative Feedback - answersreverses/reduces the effect the stimulus produced in
order to maintain homeostasis. (Ex: sweating to cool off, shivering to produce heat)
