- Define Anatomy
- Anatomy is the study of the structure of body parts & their relationship to one another.
- Define Gross/Microscopic Anatomy
- The study of large body structures visible to the naked eye. (ex. heart, lungs, kidneys)
- Define Regional Anatomy
- In regional anatomy, all the structures in a particular region are examined at the same time. (one approach of gross anatomy)
- Define Systemic Anatomy
- When anatomy is studied system by system (ex. cardiovascular)
- Define Surface Anatomy
- The study of internal structures as they relate to overlying skin surface. (ex. muscles, blood vessels)
- Define Microscopic Anatomy
- When structures are too small to be seen with the naked eye.
- Define Cytology
- The study of cells
- Define Histology
- The study of tissues
- Define Physiology
- The study of the function of the body - how all the body parts work/carry out activities.
- Define Renal Physiology
- Kidney function/urine production
- Define Neuro Physiology
- Workings of the Nervous System
- Define Cardiovasuclar Physiology
- Function of the heart & blood vessels
- Developmental Physiology
- Traces structural changes that occur in the body throughout life.
- Explain the Principle of Complementarity of Structure and Function
- Think FORM & FUNCTION - "Function always reflects structure"
- Bones...
- Bones support & protect body organs
- Blood...
- Blood flows in one direction, because the heart has valves that prevent backflow.
- Lungs...
- Lungs are where gas exchange occurs because the wall (alveoli/air sacs) are very thin.
- Name the levels of Structural Organization.... (8)
- Atoms, Molecule, Organelles, Cells, Tissues, Organs, Organ Systems, Human Organism
- Define Atoms
- Atoms are the building blocks of matter
- Define Molecule
- Bonded atoms which form larger particles
- Define Organelles
- Small structures found in a cell.
- Cells
- The basic unit of life. Smallest unit of living things.
- Define Tissues
- There are 4 types - Tissues are cells that are organized into layers or masses that have a common function.
- 1st tissue - Epithelium
- covers the body surface & lines it's cavities
- 2nd tissue - Muscle
- Muscle provides movement
