Medical Terminology

This lecture explains how the body is organized from cells to tissues to organs to systems, introduces combining forms, and covers anatomical position, body planes, and organ systems.

Explore the body's dorsal and ventral cavities—cranial, spinal, thoracic, and abdominal pelvic—highlighting viscera, membranes, and key routes of drug administration.

Explore how the integumentary system—the skin and its accessory organs, including hair, nails, sweat glands, and sebaceous glands, along with epidermis and dermis—protects the body, regulates temperature, and senses touch.

Explore the integumentary system through dermatology and plastic surgery, detailing signs such as abrasion, ecchymosis, erythema, dermatitis, ulcers, and burns, plus biopsy and culture-based diagnostics and skin graft therapies.

Explore the musculoskeletal system by examining the skeleton, axial and appendicular divisions, bone structure, joints, and key terms such as periosteum, epiphysis, diathesis, ossification, and synovial joints.

Explore musculoskeletal terminology, learning bone and joint terms, prefixes and suffixes, common pathologies, imaging, and key procedures like arthroscopy and fracture care.

Explore the muscular system's role in movement, its three muscle types, key terminology, common pathologies, diagnostics like CPK and EMG, and rehabilitation principles.

Explore the cardiovascular system's role in distributing blood and removing wastes. Trace blood flow through the heart's chambers, valves, and conduction system, and distinguish systemic from pulmonary circulation.

Explore the cardiovascular system by examining arteries, capillaries, and veins, along with blood pressure, pulse, and key terms like atherosclerosis, myocardial infarction, and endocarditis.

Explore key cardiovascular terms, diagnostic methods, and treatments, including auscultation and blood pressure measurement, imaging (angiography, echocardiography), cardiac tests (electrocardiogram/ekg, holter, stress tests), and pharmacology (ace inhibitors, statins, anticoagulants, antiarrhythmics).

Explore how blood and plasma sustain life by transporting substances, supporting immunity with white cells, platelets for clotting, and blood typing concepts like ABO and Rh.

Explore the blood, lymphatic, and immune systems, covering CBC, ESR, RBC/WBC counts, coagulation, transfusion terms, phlebotomy, and autologous options, plus lymphatic organs and immunity basics.

Explore the lymphatic and immune systems, learning word parts, prefixes, suffixes, and medical terms; identify pathologies, diagnostic tests, and therapies from allergies to immunodeficiency.

Explain the respiratory system from nasal cavity to alveoli, detailing ventilation, external and internal respiration, lung anatomy, and how lung volumes and breathing mechanics enable gas exchange.

Explore respiratory system terminology, combining forms and suffixes, anatomical terms, signs and symptoms, common pathologies, and related medical specialties.

Explore respiratory diagnostics such as arterial blood gases, sputum tests, imaging, and pulmonary function tests. Learn respiratory pharmacology and procedures like bronchoscopy, CPAP, intubation, thoracentesis, and CPR.

Explore the digestive system's anatomy and physiology, from mouth and esophagus to stomach, small and large intestines, detailing digestion, peristalsis, enzymes, absorption, and elimination.

Learn how the digestive system's accessory organs, including the salivary glands, liver, pancreas, and gallbladder, produce saliva, bile, and enzymes, emulsify fats, and regulate blood sugar with insulin and glucagon.

Explore digestive system disorders from oral cavity pathologies to gastroesophageal and intestinal diseases, and learn key terms, diagnostic tests, imaging, procedures, and therapies.

Explore the urinary system's role in maintaining homeostasis through kidney function, nephron filtration, reabsorption, and secretion, and learn urinalysis indicators.

Explore the urinary system through nephrology and urology, learning signs, diseases, and treatments, from infections and bladder conditions to kidney stones and failure with dialysis, plus essential diagnostic tests.

Explore the female reproductive system, its organs, hormones, and functions, including ovulation and lactation. Examine pregnancy, fetal development, and the stages of labor from dilation to placental delivery.

Explore gynecology, obstetrics, and neonatology, and learn about signs, pathologies, tests like HPV and Pap smear, and contraception and birth-related procedures.

Explore the male reproductive system, including testes, epididymis, scrotum, vas deferens, seminal vesicles, prostate, and bulbourethral glands, and how testosterone supports sperm production.

Explore signs, symptoms, and pathologies of the male reproductive system, learn diagnostic tests such as PSA, semen analysis, digital rectal exam, and review therapies and pharmacology for urology.
