Study Notes

Anatomy 120 - Introduction to Human Anatomy - Autumn 2024

The course is taught by Dr. Sara S. Elmegarhi in the Anatomy and Embryology Department, Faculty of Medicine, University of Tripoli.
Anatomy is the study of the structure, function, and relationship of different body parts.
It is subdivided into macroscopic (gross) anatomy and microscopic (histology) anatomy.
Anatomy is a fundamental science for medicine, with applications in various specializations.
The study of anatomy dates back to prehistoric times, with early human dissection and preparations of mummies.
Early anatomical knowledge was preserved by Arab physicians, like AlBiruni, Ibn Sina, and Al Razi in the middle ages.
Andreas Vesalius was a key figure in modernizing anatomy.
Formaldehyde is a modern preservative.

Anatomy Approaches and Branches

Anatomical study can be approached regionally or systematically.
Regional anatomy examines the body by regions.
Systemic anatomy examines the body by organ systems.
Branches of anatomy include surface anatomy, radiographic/sectional/endoscopic anatomy, clinical anatomy, and developmental anatomy (embryology).
Surface anatomy studies structures visible or palpable through the skin.
Radiographic/sectional/endoscopic anatomy studies structures using imaging techniques.
Clinical anatomy applies anatomical knowledge to diagnoses and treatments.
Embryology studies the development of the body.

Descriptive Anatomic Terms

Standardized anatomical terminology is vital for communication between medical professionals, nationally and internationally.
Terms describe locations, movements, and relationships of body structures.

Anatomical Position

The anatomical position describes a standard reference position for the body.
The body is standing upright, facing forward, with the palms forward.

Anatomical Planes

The body is often described relative to imaginary planes.
Median (sagittal) plane divides the body into equal right and left halves.
Para-median planes are parallel to the median and divide the body into unequal halves.
Coronal (frontal) planes divide the body into anterior and posterior parts.
Horizontal (transverse) planes divide the body into superior and inferior parts.

Terms Describing Location and Direction

Terms like anterior (front), posterior (back), ventral (belly side), dorsal (back side), superior (above), inferior (below), proximal (closer to the trunk), distal (further from the trunk), superficial (surface), deep (below the surface), internal, and external are used to describe the relative positions of structures.

Anatomical Variations

Human anatomy shows natural variations within normal ranges.
Awareness of these variations is crucial for physical examinations, diagnoses, and treatments.

Terms Describing Movement

Flexion decreases the angle of a joint.
Extension increases the angle of a joint.
Lateral flexion is a side-to-side movement of the trunk.
Abduction moves a limb away from the midline.
Adduction moves a limb toward the midline.
Rotation involves turning a bone around its axis.

Types of Body Movement

Medial rotation—anterior surface rotates medially.
Lateral rotation—anterior surface rotates laterally.
Pronation—forearm rotation, palm posterior.
Supination—forearm rotation, palm anterior.
Circumduction—movement in a circular path.
Protraction—movement forward.
Retraction—movement backward.
Inversion—sole of foot turns medially.
Eversion—sole of foot turns laterally.

Body Parts

Axial skeleton - Head, neck, thorax, abdomen, and pelvis.
Appendicular skeleton - Limbs

Body Cavities

Ventral body cavity (anterior) encloses organs of the chest, abdomen, and pelvis.
Dorsal body cavity (posterior) encloses the brain and spinal cord.
Thoracic cavity houses the heart and lungs.
Abdominal cavity houses stomach, intestines, liver, and spleen.
Pelvic cavity houses urinary bladder, rectum, and reproductive organs.
(Note: Additional pages discuss skin structure and function, skin appendages, skin infections, and associated clinical anatomy)*
