Study Notes
Human Anatomy
- Scientific study focused on the body's structures and their locations.
- Two main subbranches: Microscopic Anatomy (studies cells and tissues using a microscope) and Gross Anatomy (examines larger structures visible to the naked eye).
Approaches to Study Body Structures
- Regional Approach: Analyzes interrelationships of structures in specific body regions, fostering a three-dimensional understanding.
- Systemic Approach: Studies the structures forming discrete body systems that work together for specific functions.
Physiology
- Examines the chemistry and physics of body structures and how they function together to sustain life.
- Focuses on the "how" of bodily components and their interdependent roles.
Themes of Anatomy and Physiology
- Explores the relationship between structure (form) and function, evolution and human variation, flow of systems, and homeostasis.
Anatomical Terms and Positions
- Directional Terms: Help locate structures (e.g., superior, inferior, anterior, posterior, medial, lateral, proximal, distal).
- Proximal and distal are specific to limbs; they denote closeness or distance to the limb's attachment.
Sections and Planes
- Section: A slice through a three-dimensional structure.
- Plane: An imaginary division of the body for imaging purposes.
- Major anatomical planes include:
- Sagittal Plane: Divides body into right and left halves.
- Frontal (Coronal) Plane: Divides body into anterior and posterior portions.
- Transverse Plane: Divides body into superior and inferior sections.
Body Compartmentalization
- Body compartments are divided by membranes, protecting internal organs.
- Two largest body compartments:
- Posterior Cavity: Contains the cranial and spinal cavities.
- Anterior Cavity: Comprises thoracic and abdominopelvic cavities.
Membranes of the Anterior Body Cavity
- Serous Membranes (serosa): Cover body walls and organs, forming fluid-filled sacs for cushioning.
- Parietal Layer: Lines cavity walls.
- Visceral Layer: Covers organs.
- Major serous cavities include the Pleura, Pericardium, and Peritoneum.
Body Regions
- Divided into Axial Region (head and trunk) and Appendicular Region (limbs).
- Specific parts include:
- Head (Cephalic): Skull and face.
- Neck (Cervical): Connects head and trunk.
- Trunk: Includes chest, abdomen, pelvis, and back.
- Limbs: Upper and lower limbs with distinct regions.
Anatomical and Directional Terminology
- Defines specific body regions and structures (e.g., cranial, facial, thoracic, lumbar).
- Directional terms aid in understanding body orientation and positioning.
Key Points in Anatomical Terminology
- Form closely relates to function, as seen in protein structure and bipedalism in humans.
- Anatomical terms like superficial (near surface) and deep (internal) help standardize reference points in anatomy.
