Class Program
Degree Code
Lab Science
Credits 5 Lecture Hours 33 Lab Hours 44

An analysis of the structure and function of human skeletal, muscular, and nervous systems as well as the role of receptor-ligand interactions and introductory histology. Emphasis will be given to the homeostatic relationships between systems. Four hours of lab per week will be devoted to exploring these systems. Lab participation is required for credit.

Prerequisites

A grade of 2.0 or better in BIOL& 160, BIOL& 211, or BIOL& 222, and in CHEM& 121 or above, or on a college transcript within the last 5 years, or instructor permission.

Course Outcomes

Upon successful completion of the course, students should be able to demonstrate the following knowledge or skills:

  1. Develop a vocabulary of appropriate terminology to effectively communicate information related to anatomy and physiology.
  2. Use the concept of homeostasis to evaluate cause and effect relationships between and within the regulatory mechanisms of multiple body systems.
  3. Locate and identify all major bones, bony landmarks, joints and muscles in human skeletons and models
  4. Identify and describe all major tissues on microscope and digital slides, relating form to function.
  5. Describe and explain the form, function and interrelationships of the muscular, skeletal, nervous and systems and the major diseases and disorders of each. Relate form to function.

Department Guidelines
  • The overall course percentage will be based on the following weighted categories:
    • Lecture exams (including 2-4 tests plus a comprehensive final exam) collectively worth 45-50%,
    • Laboratory work collectively worth 40%, and
    • Class assignments/quizzes collectively worth 10-15% of the overall score.
  • A standard grade scale will be used for this course with a 2.0 grade point corresponding to 72%.
  • All exams are proctored. When possible, exams are held on campus. Online and hybrid courses may have exams online, but they must be proctored to ensure academic honesty.
  • Lab is an essential part of this class and is required for credit. Students missing more than two labs will not be given credit for this course.
  • PO5 should be assessed: Students will be able to solve problems by gathering, interpreting, combining and/or applying information from multiple sources.
