35-101. Human Anatomy and Physiology 1
Fall semester, 2013
Exam 2 on Wednesday, October 16, will cover the following:
Chapter 4 – The Biology of the Cell: The following are highlights of the chapter.
 The structure of the cell membrane, including the ion channel functions as given
in the assigned reading.
 The structure and function of all the cytoplasmic organelles.
 The cell cycle and its components, as well as the details of all the stages of
somatic cell division with mitosis. Gametic cell division and meiosis will NOT be
included.
 All the ways of getting solutes and solvents across a cell membrane. You should
know which processes are active and which are passive. Be able to define the
processes, and the forces that drive molecules across a cell membrane.
Chapter 5 – Tissue organization; histology
You should know only the tissue descriptions, functions, and and/or locations as we
discussed them in class, and according to the assignment on your handout sheet.
Chapter 6 – The integumentary system
As given on your syllabus.
