Study Notes
Introduction to Anatomy
- Anatomy is the science that studies body structures and their relationships.
- It also involves studying the organization of the body, progressing from smallest to largest components.
Levels of Organization
- Cellular level: Basic structural and functional units, such as epithelial cells.
- Tissue level: Groups of similar cells performing specific functions, like muscular tissue.
- Organ level: Composed of different tissue types performing specific functions, such as muscles and nerves.
- System level: Groups of related organs with common functions, like the digestive system.
- Body level: The human body as a whole.
Medical Language
- Medical language primarily derives from Latin and Greek.
- This terminology is crucial for clear communication in medicine.
Basic Word Parts
- Word Root: The origin of a word, like "gastr" for stomach.
- Suffix: Word endings, like "-itis" for inflammation.
- Prefix: Word beginnings, like "epi" for above.
- Combining Vowel: Connects word roots and suffixes (usually "o").
Example of Combining Parts
- Tonsillitis: "Tonsil" + "-itis" (inflammation) = inflammation of the tonsils.
Anatomical Position
- The standard reference position for describing body structures.
- Person is standing upright, facing forward, with arms at the sides, and palms forward, and feet together.
Planes of the Body
-
Sagittal plane: Divides the body into right and left sections.
- Median sagittal plane: divides the body into equal halves.
- Paramedian plane: divides the body into unequal halves.
- Coronal (Frontal) plane: Divides the body into front and back sections.
- Horizontal (Transverse) plane: Divides the body into top and bottom sections.
Directional Terms
- Superior: Towards the head; above.
- Inferior: Towards the feet; below.
- Anterior (Ventral): Towards the front.
- Posterior (Dorsal): Towards the back.
- Medial: Towards the midline.
- Lateral: Away from the midline.
- Proximal: Closer to the point of attachment or origin.
- Distal: Farther from the point of attachment or origin.
- Superficial: Nearer to the body surface.
- Deep: Farther from the body surface.
- Cranial: Towards the head.
- Caudal: Towards the tail.
