Study Notes
Introduction to Anatomy
- Anatomy is the scientific study of the structure of organisms and their parts.
- It includes the form and organization of living things, from cells to complete organisms.
- Various sub-disciplines exist, based on organism type, system studied, or method of examination.
Anatomical Position
- Anatomical position is a standardized reference point for describing human body structures.
- This position aids doctors and researchers by ensuring consistent anatomical descriptions.
- Body erect, feet flat, facing forward.
- Arms at sides, palms forward (supine).
- Head level, eyes looking forward.
Directional Terms
- Directional terms specify the relative positions of structures within the body.
- Superior (cranial): Towards the head or upper part.
- Inferior (caudal): Away from the head or towards the lower part.
- Anterior (ventral): Towards the front.
- Posterior (dorsal): Towards the back.
- Medial: Towards the body's midline.
- Lateral: Away from the body's midline.
- Proximal: Closer to the origin or point of attachment.
- Distal: Further from the origin or point of attachment.
- Superficial: Closer to the body surface.
- Deep: Further from the body surface.
Body Planes and Sections
- Planes are imaginary flat surfaces used to create sections of the body.
- Sagittal plane: Divides the body into left and right sections.
- Mid-sagittal plane: Passes directly through the middle.
- Parasagittal plane: Offsets the midline.
- Coronal (frontal) plane: Divides the body into anterior and posterior sections.
- Transverse (horizontal) plane: Divides the body into superior and inferior sections.
- Sagittal plane: Divides the body into left and right sections.
Body Cavities
- Body cavities are enclosed spaces protecting internal organs.
- Dorsal cavity: Cranial cavity (brain) and vertebral canal (spinal cord).
- Ventral cavity: Thoracic cavity (heart and lungs) and abdominopelvic cavity (stomach, intestines, etc.).
- Thoracic cavity subdivisions: Pleural cavities (lungs) and mediastinum (heart, esophagus, trachea).
- Diaphragm separates thoracic and abdominopelvic cavities.
Body Regions and Quadrants
- Regional terms name specific body parts.
- Quadrants and nine regions section the abdominopelvic cavity for systematic description.
Anatomical Terminology - Abbreviated Forms
- Common abbreviations for anatomical structures and regions.
- Examples: L5 (fifth lumbar vertebra), RUL (right upper lung lobe).
Levels of Structural Organization
- Cells: Basic structural and functional units.
- Tissues: Groups of similar cells with a shared function.
- Organs: Structures of two or more tissue types working together.
- Organ systems: Groups of organs working together for a specific function.
- Organism: The complete living being.
Microscopic Anatomy
- Examination of structures needing magnification.
- Cytology: Study of cells.
- Histology: Study of tissues.
Systemic Anatomy
- Study of specific organ systems:
- Skeletal system
- Muscular system
- Nervous system
- Cardiovascular system
- Respiratory system
- Digestive system
- Urinary system
- Endocrine system
- Reproductive system, etc.
