[UNIT 1 Study Guide]
**This is a guide of what will be on the test, not a guarantee, but it should help direct your studying.
An Overview of Anatomy and Physiology
- Distinguish between anatomy and physiology and understand their relationship.
Levels of Structural Organization
- Order levels of structure, define each one, and be able to give an example (atoms, molecules, cells, tissues,
organs, organ system, organism)
Organ system overview
- Identify organs and functions of each of the 11 organ systems and be able to name all 11 organ systems.
Maintaining life functions
- Be able to list and define all seven life functions
- For each life function, give one example of how a body system assists in that function.
- List the five survival needs and explain the importance of each one.
Homeostasis
- Define homeostasis and understand roles of the receptor, control center, and effector, stimulus, response,
afferent, and efferent pathways.
- Given an example, be able to identify stimulus, input, effector, response, control center, afferent, and
efferent pathways.
- Distinguish between positive and negative feedback mechanisms and give an example of each.
- Be able to give an example of how the body maintains homeostasis during exercise.
The Language of Anatomy
- Define anatomical position
- Define and be able to use directional terms listed on table 1.1 (superior, inferior, ventral, dorsal, medial,
lateral, proximal, distal, superficial, deep).
- Differentiate between median (midsaggital), frontal (coronal), and transverse planes, given a picture or
description.
- Know figure 1.5 and the definitions for each region.
- Identify/define body cavities (cranial, thoracic, spinal, abdominopelvic, ventral, and pelvic), the
mediastinum, and diaphragm from a written description or on a diagram. You should know which cavities
are parts of other cavities.
