Study Notes
Introduction
- Anatomy is the study of structure, while physiology is the study of function
- Macroscopic anatomy examines large structures visible without magnification (e.g., organs, limbs)
- Microscopic anatomy examines small structures needing magnification (e.g., cells, tissues)
- Structure and function are interconnected in the human body
- Levels of organization (smallest to largest): chemical, cells, tissues, organs, organ systems, organism
- Major organ systems in the body and their functions
Organ System Functions
- Integumentary: protects internal structures, regulates temperature, sensory reception
- Skeletal: support, protection, assists with movement, blood cell production
- Muscular: movement, generates heat
- Nervous: controls and coordinates body functions
- Endocrine: regulates growth, development, and body functions using hormones
- Cardiovascular: delivers nutrients and oxygen to tissues, removes waste
- Lymphatic: filters fluid leaking from tissues, manages immune response
- Respiratory: gas exchange, pH balance
- Urinary: blood filtration, fluid, electrolyte, and pH balance
- Digestive: digests food, absorbs nutrients, eliminates waste
- Reproductive: hormone and gamete production, perpetuation of species
Homeostasis
- Maintaining stable internal conditions
Control System Elements
- Regulated variable
- Stimulus
- Receptor
- Effector
- Integrator
Feedback Mechanisms
- Negative feedback: returns body to normal range
- Positive feedback: pushes system further from normal range, with a clear end-point
Anatomical Position
- Standing upright, feet facing forward, arms at sides, palms forward
Body Cavities
- Cranial cavity (brain)
- Spinal cavity (spinal cord)
- Thoracic cavity (heart and lungs)
- Abdominal cavity (stomach, liver, etc)
- Pelvic cavity (uterus and parts of the large intestine)
- Dorsal cavity (posterior)
- Ventral cavity (anterior)
Directional Terms
- Superior/inferior
- Medial/lateral
- Proximal/distal
- Anterior/posterior
- Ventral/dorsal
- Cranial/caudal
- Superficial/deep
Body Planes
- Transverse: divides body into top and bottom halves
- Coronal: divides body into front and back halves
- Sagittal: divides body into left and right portions
- Midsagittal: equal left and right halves
- Parasagittal: unequal left and right halves
Abdominopelvic Regions/Quadrants
- Quadrants (RUQ, LUQ, RLQ, LLQ) and regions
- Major organs located in each region/quadrant
Tissues
- Epithelial: covering and lining tissues / Simple and stratified
- Connective: support tissues / Cartilage, bone, blood, etc.
- Muscle: movement / Skeletal, smooth, cardiac
- Nervous: communication / Neurons, glial cells
Cell Types
- Squamous
- Cuboidal
- Columnar
Epithelial Membranes
- Mucous, serous, cutaneous
Integumentary System
- Functions of integumentary system; Skin structure and layers (epidermis and dermis)
- Cell types in the epidermis
- Hypodermis
- Accessory structures (hair, nails, glands)
