Study Notes
Overview of Human Anatomy
- Study of the structure and organization of living things
- Focuses on the internal and external features of the body
- Divided into macroscopic (gross) anatomy and microscopic anatomy
Organization of the Human Body
- Chemical level: atoms, molecules, and compounds
- Cellular level: cells, tissues, and organs
- Tissue level: four primary tissue types (epithelial, connective, muscle, and nervous)
- Organ level: functional units that perform specific tasks
- Organ system level: groups of organs that work together to maintain homeostasis
- Organismal level: the entire human body
Body Cavities
- Dorsal cavity: contains the brain and spinal cord
- Ventral cavity: contains the thoracic and abdominopelvic cavities
- Thoracic cavity: contains the heart, lungs, and thoracic organs
- Abdominopelvic cavity: contains the abdominal and pelvic organs
Body Regions
- Axial region: head, neck, thorax, and abdomen
- Appendicular region: upper and lower limbs
- Regional anatomy: study of specific body regions
Directional Terms
- Anatomical position: standing upright, feet shoulder-width apart, and palms facing forward
- Superior: above or higher
- Inferior: below or lower
- Anterior: front or forward
- Posterior: back or rear
- Medial: towards the midline
- Lateral: away from the midline
- Proximal: closer to the trunk
- Distal: farther from the trunk
Body Systems
- Nervous system: controls and coordinates body functions
- Circulatory system: transports oxygen and nutrients to cells
- Respiratory system: brings oxygen into the body and removes carbon dioxide
- Digestive system: breaks down and absorbs nutrients
- Endocrine system: produces and regulates hormones
- Immune system: defends the body against pathogens and diseases
- Muscular system: moves the body and maintains posture
- Skeletal system: provides support, protection, and movement
- Integumentary system: protects the body and regulates body temperature
This quiz covers the basics of human anatomy, including the organization of the human body, body cavities, body regions, directional terms, and the different body systems.
