Study Notes
Introduction to Anatomy
- Anatomy derives from the Greek word ἈΝΑΤΈΜΝΩ, meaning "I cut up, cut open."
- Anatomy is organized by systems including the upper and lower limbs, musculoskeletal, gastrointestinal, endocrine, immune, cardiovascular, respiratory, nervous, urinary, and reproductive systems.
Embryology and Histology
- Embryology consists of general and special categories.
- Histology is the study of tissues at the microscopic level.
Study Techniques for Anatomy
- Respect the subject and visualize concepts during study.
- Engage in practical classes and discussions.
- Teaching others can reinforce your understanding.
- Continuous reading and drawing improve comprehension.
Levels of Organization
- The human body is structured in a hierarchy: cells, tissues, organs, and systems.
Anatomical Position
- Standing erect with arms at the sides, face, and palms facing forward, and feet positioned together.
Anatomical Planes
- Median Sagittal Plane: Vertical, divides the body into equal right and left halves.
- Coronal Plane: Divides the body into anterior (front) and posterior (back) sections.
- Transverse Plane: Divides the body into superior (upper) and inferior (lower) parts.
Anatomical Terminology: Positions and Directions
- Anterior (Ventral): More in front (e.g., ribs are anterior to lungs).
- Posterior (Dorsal): More in back (e.g., lungs are posterior to ribs).
- Superior: Higher position (e.g., head is superior to chest).
- Inferior: Lower position (e.g., chest is inferior to head).
- Medial: Closer to midline; Lateral: Farther from midline.
- Proximal: Closer to origin (e.g., elbow is proximal to wrist); Distal: Farther from origin (e.g., wrist is distal to elbow).
- Superficial: Nearer to surface; Deep: Away from surface.
- Ipsilateral: Same side; Contralateral: Opposite side.
- Supine: Lying face up; Prone: Lying face down.
Anatomical Terminology: Movement Terms
- Flexion: Bending movement.
- Extension: Straightening movement.
- Abduction: Movement away from midline.
- Adduction: Movement toward midline.
- Medial rotation: Rotation toward the body center.
- Lateral rotation: Rotation away from the body center.
- Pronation: Medial rotation of the forearm.
- Supination: Lateral rotation of the forearm.
- Elevation: Movement upward.
- Depression: Movement downward.
- Inversion: Movement of the sole toward the median plane.
- Eversion: Movement of the sole away from the median plane.
- Dorsiflexion: Raising foot upwards.
- Plantarflexion: Lowering foot downwards.
- Retraction: Moving a part backward.
- Protraction: Moving a part forward.
- Opposition: Movement of the thumb across the palm.
Nervous System Overview
- Somatic Nervous System: Contains 31 pairs of spinal nerves and 12 pairs of cranial nerves.
- Autonomic Nervous System: Divided into sympathetic and parasympathetic divisions.
Blood Vessels Functions
- Arteries carry oxygenated blood from the heart; veins return deoxygenated blood.
- Each artery has branches, while veins have tributaries.
Fascia Types
- Superficial Fascia: Mixture of loose areolar and fatty tissue, acts as an insulator and fills body surface irregularities.
- Deep Fascia: Denser, surrounds muscles and structures, keeps them in place, forms sheaths and membranes.
Body Cavities
- Thoracic Cavity: Contains the heart, lungs, and major blood vessels; bounded by ribs and diaphragm.
- Abdominopelvic Cavity: Includes the abdominal cavity (gastrointestinal tract, kidneys) and pelvic cavity (urogenital system, rectum).
- Dorsal Cavity: Houses the brain (cranial cavity) and spinal cord (vertebral canal).
