Study Notes
Introduction to Anatomy
- Anatomy's roots are Indo-European.
- The Greek term for anatomy is "anatome", meaning "dissection".
- Latin equivalent is "anatomia"; Old French as "anatomie".
- English uses "anatomy".
- The intricate nature of the human body makes it a mysterious subject.
- Dissection is crucial for understanding human anatomy
- Dissection utilizes touch and sight for better understanding.
- Anatomy studies the structure of the body (normal).
- It includes the form, position, size, and relationship of body structures in a healthy state.
History of Anatomy
- Hippocrates (1600 BC) provided basic understanding of musculoskeletal structures.
- Much of Hippocrates' work relied on speculation.
- Galen compiled knowledge from previous writers.
- Galen's work advanced understanding of organ function through vivisection on animals.
- The 16th century marked a shift in anatomy.
- Mondino de Liuzzi and Alessandro Achillini were pioneers in dissecting cadavers.
- Public anatomical demonstrations became common.
The Rebirth of Anatomy
- Andreas Vesalius challenged Galenic doctrine.
- Vesalius's treatise "De humani corporis fabrica" detailed major body organs.
- Vesalius obtained permission to dissect human bodies.
- Andreas Vesalius's work was improved upon by Columbus.
- Columbus corrected work on bone anatomy, heart cavities.
- Columbus correctly detailed the pulmonary artery, aorta, and heart valves.
Further Developments in Anatomy
- Leonardo da Vinci noticed abnormalities in dissected corpses.
- Giovanni Morgagni is considered the father of modern pathology.
- Marcello Malpighi used microscopes in anatomy and histology.
- Malpighi studied the skin and brain's cerebral area.
- Antonie van Leeuwenhoek used single lenses.
- Leeuwenhoek achieved high magnification (40-270 diameters).
- Leeuwenhoek observed protozoa.
Advancements in the 20th Century
- Anatomy progressed to encompass histology & developmental biology.
- 20th-century radiological advances connected anatomy & physiology.
- Anatomy linked with biochemistry, genetics, & biophysics.
- Radiological advances form the basis of successful imaging.
- Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) revolutionized sectional anatomy.
Branches of Anatomy
- Anatomy has expanded to include various fields.
- Gross anatomy studies visible structures with the naked eye.
- Developmental anatomy details intrauterine development stages from fertilization to birth.
- Histology studies minute structures invisible to the naked eye.
- Cytology examines body cells.
- Comparative anatomy studies animal anatomy using a human ancestry framework.
- Pathological anatomy investigates disease conditions.
- Functional anatomy links structure with function.
- Anthropological anatomy compares the anatomy of different races.
- Surface/Superficial anatomy studies easily visible anatomical landmarks.
Anatomical Orientations and Terms
- Anatomical orientations use imaginary planes through the body.
- Standard anatomical position: standing upright, feet planted, facing forward, arms hanging with palms forward.
- Sagittal/median plane divides the body into left and right halves.
- Coronal/frontal plane divides the body into front and back halves.
- Transverse/cross plane divides the body into upper and lower halves.
- Oblique plane cuts across the body in an angle.
- Directional terms: cranial/superior/rostral, caudal/inferior, anterior/ventral, posterior/dorsal, medial, lateral.
- Proximal, distal, superficial, deep, ipsilateral, contralateral, external/internal.
Embryology and Prenatal Development
- Embryology studies embryo formation and development.
- Embryology extends from conception to birth as an infant.
- Prenatal period: Starts with zygote formation (fertilization of oocyte by sperm); marks the beginning of human development.
- Morula is the stage where 16 blastomeres form a solid mass of cells.
- Blastocyst: Morula develops a cavity.
- Embryo: Cells develop into an inner cell mass (embryoblast) .
- Embryonic development continues until 2 weeks, when a bilaminar embryonic disc forms .
- Foetus is the period following the embryonic stage.
- Post-natal stage: changes occurring after birth.
- Infancy: First year after birth
- New-born: first two weeks after birth.
Child Development & Puberty
- Childhood lasts approximately up to 12-13 years of age (approximately 15 months to 12-13 years).
- Puberty: age 12-15 (girls) and 13-16 (boys), secondary sexual characteristics develop.
- Adolescence period: 3-4 years following puberty; extends from the emergence of sexual maturity to the completion of physical, mental, and emotional maturation.
