Study Notes
Anatomy Definition
- Anatomy is the branch of biology studying the structure and organization of living organisms.
- Focuses on forms, relationships, and arrangements of body parts.
- Essential for fields like medicine, biology, and physical therapy.
Subdivisions of Anatomy
- Macroscopic Anatomy (or Gross Anatomy): The study of organs using the naked eye. Includes positions, shapes, dimensions, and vascularization.
- Microscopic Anatomy (Histology): Studies the structure of tissues under a microscope.
- Comparative Anatomy: Studies and compares human structures to those of other animals.
- Clinical Anatomy: Examines the clinical implications of anatomical structures.
- Radiological Anatomy: Important for interpreting X-ray images and other medical imaging.
- Developmental Anatomy (or Embryology): Studies the development of the body from fertilization.
- Topographic (or Regional) Anatomy: Focuses on relationships between organs within specific regions of the body.
- Functional Anatomy: Explores the relationship between organ anatomy and their functionality.
Methods of Studying Anatomy
- Direct Methods:
- Dissection: Provides a direct view of the body. Involves inspection, palpation, auscultation, measurements, and weighing.
- Plastinations, casts, and models: Provide alternatives to traditional dissection.
- Indirect Methods:
- Medical imaging techniques:
- X-ray (Rx): Uses electromagnetic radiation to create images of internal structures.
- Computed tomography (CT): Combines X-ray images to create cross-sectional views.
- Magnetic resonance imaging (MRI): Uses magnetic fields and radio waves to create detailed images of tissues.
- Positron emission tomography (PET SCAN): Uses radioactive tracers to visualize metabolic activity.
- Medical imaging techniques:
Anatomical Terminology
- Basel Nomina Anatomica (BNA) (1895): The first anatomical nomenclature.
- Parisiensia Nomina Anatomica (PNA) (1955): A revision of the BNA.
- Terminologia Anatomica (TA) (1998): The latest revision, adopted internationally.
Rules of the Nomina Anatomica
- Primarily uses Latin.
- Each structure has a single designated name.
- Terms should be simple and memorable.
- Eponyms (proper names) are removed.
- Synonyms are eliminated.
- Structures within the same region use similar adjectives.
Anatomical Reference Position
- Standard reference position for describing the human body.
- Subject stands upright.
- Upper limbs hang by the side, palms facing forward.
- Feet parallel, gaze directed straight ahead and horizontally.
Reference Planes and Axes
- Axes:
- Transverse Axis: Runs horizontally from right to left.
- Sagittal Axis: Runs vertically from front to back.
- Longitudinal Axis: Runs vertically along the length of the body.
- Hand and Foot Axis: Runs longitudinally through the 3rd finger (or 2nd toe).
- Planes:
- Sagittal Plane: Divides the body into right and left parts.
- Coronal (Frontal) Plane: Divides the body into front (anterior) and back (posterior) parts.
- Axial (Transverse) Plane: Divides the body into upper and lower parts.
Terms for Location
- Median Plane: A sagittal plane passing through the body's axis.
- Parasagittal Plane: Any plane parallel to the sagittal plane.
- Anterior (Ventral): Toward the front.
- Posterior (Dorsal): Toward the back.
- Superior (Cranial): Upward; toward the head.
- Inferior (Caudal): Downward; toward the tailbone.
- Medial (Internal): Toward the middle; close to the median plane.
- Lateral (External): Away from the median plane.
- Superficial (Peripheral): Close to the body's surface.
- Deep (Central): Far from the surface; inward.
- Intermediate: Between two structures.
- Proximal: Close to the trunk or median axis.
- Distal: Away from the trunk or median axis.
