Introduction to Anatomy & Physiology Laboratory

Overview

This section introduces students to the essential safety protocols, terminology, and foundational concepts necessary for success in an Anatomy & Physiology laboratory setting. Understanding these principles is crucial for both personal safety and effective scientific learning.

Lab Safety in Anatomy & Physiology

General Laboratory Safety

• Personal Protective Equipment (PPE): Always wear goggles, gloves, and lab coats to protect against chemical and biological hazards.

• Emergency Equipment: Know the location and proper use of fire extinguishers, fire blankets, safety showers, and first aid kits.

• Biohazard Containers: Dispose of biological and chemical waste in designated containers to prevent contamination.

• Emergency Procedures: Be familiar with the location of the emergency exit, eye wash station, and emergency contact numbers (e.g., 515-8911).

• General Conduct: Do not use sinks in the bench for hazardous waste. Never work without instructor supervision. Do not enter the lab if the instructor is not present.

Safety Data Sheets (SDS)

• Definition: SDS are technical documents that provide detailed information about hazardous chemicals used in the laboratory.

• Contents: Includes product identification, ingredient information, hazard identification, first aid measures, firefighting procedures, and disposal guidelines.

• Legal Requirement: Texas Hazard Communication Act requires SDS to be available for each hazardous chemical stored or used in educational settings.

• Access: Sheets must be readily accessible for reference by employees and students. Ask your instructor for the location in the lab.

Appropriate Personal Attire

• Footwear: Wear closed-toed shoes that cover the entire foot. Sandals, canvas shoes, and flip-flops are not permitted.

• Clothing: Avoid loose or floppy clothing, which can catch fire or become entangled in equipment.

• Coverage: Arms, legs, and midriff should be covered to protect from chemical spills and burns.

• Hair: Tie back long hair to prevent contact with flames and chemicals.

• Additional info: Do not wear pantyhose/tights, as these can melt in a fire.

Laboratory Preparation and Conduct

Preparation Before Experiments

• Read Procedures: Carefully read all experimental procedures and be aware of any associated hazards.

• Health Disclosure: Inform your instructor of any allergies, pregnancy, or specific health conditions. Indicate if you wear contact lenses.

• Safety Agreement: Complete the Safety Agreement Form with all relevant information before beginning lab work.

Clean-Up and Hygiene

• Disinfection: Clean and disinfect your lab table with Lysol before and after performing experiments.

• Proper Waste Disposal: Dispose of all materials according to lab protocols.

The Language of Anatomy

Introduction to Anatomical Terminology

Understanding anatomical terminology is essential for accurately describing the location, orientation, and relationships of body structures.

• Anatomical Position: The standard reference position for the body in the study of anatomy. The body stands upright, facing forward, with arms at the sides and palms facing forward.

• Importance: Provides a consistent frame of reference for anatomical descriptions.

Body Regions, Orientation, and Planes

• Body Regions: Specific areas of the body identified by unique terms (e.g., thoracic, abdominal, pelvic).

• Body Planes:

  • Midsagittal Plane: Divides the body into equal left and right halves.

  • Parasagittal Plane: Divides the body into unequal left and right portions.

  • Frontal (Coronal) Plane: Divides the body into anterior (front) and posterior (back) sections.

  • Transverse (Horizontal) Plane: Divides the body into superior (upper) and inferior (lower) parts.

Body Cavities and Membranes

• Major Body Cavities:

  • Dorsal Cavity: Contains the cranial and vertebral cavities.

  • Ventral Cavity: Includes the thoracic and abdominopelvic cavities.

• Serous Membranes: Thin membranes lining the body cavities and covering organs, providing lubrication and protection.

Abdominopelvic Regions and Quadrants

• Four Quadrants: Right Upper, Left Upper, Right Lower, Left Lower. Used to describe locations of organs and pain.

• Nine Regions: More precise divisions (e.g., epigastric, umbilical, hypogastric, etc.) for anatomical study.

• Example: The appendix is located in the right lower quadrant.

Organ Systems Overview

Major Organ Systems

Each organ system consists of specific organs that work together to perform vital functions necessary for life.

• Examples of Organ Systems:

  • Cardiovascular System: Heart, blood vessels; transports nutrients and oxygen.

  • Respiratory System: Lungs, diaphragm, trachea; responsible for gas exchange.

  • Digestive System: Esophagus, stomach, intestines, pancreas, liver, gall bladder, appendix; processes food and absorbs nutrients.

  • Urinary System: Kidneys, ureters, bladder; removes waste from blood.

  • Endocrine System: Adrenal glands, pancreas; regulates body functions via hormones.

  • Lymphatic System: Spleen; defends against infection.

Summary

• Lab safety and proper attire are essential for a safe and productive learning environment.

• Understanding anatomical terminology and body organization is foundational for all further study in Anatomy & Physiology.

• Familiarity with organ systems and their functions is crucial for understanding human biology and health.
