Body Organization
- The human body is divided into the Axial Portion (head, neck, trunk) and Appendicular Portion (upper and lower limbs).
- Major cavities include the cranial cavity (houses the brain), vertebral canal (encloses the spinal cord), thoracic cavity (contains lungs), and abdominopelvic cavity (holds internal organs).
Cavity Descriptions
- Cranial Cavity: Part of the axial portion that protects the brain.
- Vertebral Canal: Encloses the spinal cord, surrounded by vertebrae.
- Thoracic Cavity: Contains lungs and is separated by the diaphragm from the abdominopelvic cavity.
- Abdominopelvic Cavity: Houses digestive organs, urinary bladder, and reproductive organs.
Membranes and Structures
- Diaphragm: A muscle separating thoracic and abdominal cavities that moves during breathing.
- Mediastinum: Area between the lungs that contains the heart, esophagus, trachea, and thymus.
- Serous Membranes: Line thoracic and abdominal cavities, secreting fluid to reduce friction and protect organs.
Terminology in Anatomy
- Anatomical Position: Standing with face forward, upper limbs at sides, and palms facing forward.
- Directional Terms:
- Superior: Above another part.
- Inferior: Below another part.
- Anterior (Ventral): Front side.
- Posterior (Dorsal): Back side.
- Medial: Closer to the midline.
- Lateral: Farther from the midline.
- Bilateral: Paired structures on each side.
- Ipsilateral: Structures on the same side.
- Contralateral: Structures on opposite sides.
Region and Quadrant Organization
- Regions of the Abdominal Area:
- Epigastric, Hypochondriac (left/right), Umbilical, Lumbar (left/right), Hypogastric, Iliac (left/right).
- Abdominal Quadrants:
- RUQ (Right Upper Quadrant), RLQ (Right Lower Quadrant), LUQ (Left Upper Quadrant), LLQ (Left Lower Quadrant).
Anatomical Sections
- Sagittal Section: Divides body into right and left. Median (midsagittal) divides equally.
- Transverse Section: Divides body into superior and inferior.
- Frontal Section: Divides body into anterior and posterior.
- Cross Section: A vertical cut across the body.
Additional Key Terms
- Epidermis: The outer layer of skin.
- Peripheral/Superficial: Near the surface.
- Deep: More internal structures.
- Proximial: Closer to the trunk or point of reference.
- Distal: Farther from the trunk or point of reference.
These terms and structures are essential for understanding human anatomy and its organization.
