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.

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.
