Muscular System Vocabulary
Medical Terms Describing Muscular Pathology
Understanding the terminology related to muscular system pathology is essential for accurate diagnosis, treatment, and communication in medical settings. Below are key terms, their definitions, and memory aids.
Medical Term | Definition | Memory Tool |
|---|---|---|
RICE (First Aid Treatment) | First aid to treat pain & body damage | Rest, Ice, Compression, Elevation |
Talipes (Clubfoot) | Deformity where congenital abnormality affects foot position and movement | "Eating in Pain" (club foot) |
Ganglion Cyst | Small lump that appears near tendons or joints | Oval cyst on wrist |
Carpal Tunnel Syndrome | Median nerve compression causing pain and numbness | Hand tingling |
Greenstick Fracture | When bone is bent and partially breaks (common in children) | "The Walking Bend Break" |
Flexed | Muscle in a contracted position | Puppy Fist |
Tetany | Involuntary muscle spasm and contraction | Tightness |
Rigor Mortis | Stiffness of skeletal muscle after death | Rigid Muscles |
Examples and Applications
RICE is commonly used for sprains and strains to reduce swelling and pain.
Carpal Tunnel Syndrome is often seen in individuals performing repetitive wrist movements.
Tetany can result from low calcium levels (hypocalcemia).
Body Positions
Medical Terms for Body Positioning
Body positioning terms are used to describe the orientation of the human body, especially during examinations and surgical procedures. These terms are crucial for clear communication in clinical settings.
Medical Term | Definition | Memory Tool |
|---|---|---|
Lateral | Body lying on one side with top leg in front | "Lateral Left and Right" |
Fowler | Sitting position with body elevated at around 45° angle | "Fowler Recliner" |
Trendelenburg | Body lying face up with head lower than feet | "Head Trending down" |
Orthopneic | Sitting leaning forward and resting arms on knees or table to improve breathing | "Orthopedic breathing" |
Lithotomy | Body supine, legs elevated in stirrups | "Lift in Litho" |
Examples and Applications
Fowler position is used for patients with respiratory distress.
Trendelenburg position is used to improve venous return or during certain surgical procedures.
Lithotomy position is commonly used for gynecological exams and procedures.
Diagnostic and Laboratory Terms
Enzyme and Blood Tests Related to the Muscular System
Diagnostic and laboratory terms help in evaluating muscle damage and function. Enzyme tests and blood calcium levels are commonly used in clinical practice.
Test | Purpose | Notes |
|---|---|---|
Lactic Dehydrogenase Blood Test (LD) | Measures enzyme released by damaged cells | General tissue damage |
Creatine Kinase Blood Test (CK) | Measures enzyme released by skeletal muscle damage | Specific for muscle injury |
Aldolase Blood Test (ALD) | Measures enzyme released by skeletal muscle | Indicates muscle breakdown |
Calcium Blood Test | Measures blood calcium | Low calcium can cause muscle cramps and numbness |
Examples and Applications
Creatine Kinase Blood Test is used to diagnose conditions such as myositis and rhabdomyolysis.
Lactic Dehydrogenase Blood Test is used to detect general tissue damage, including muscle injury.
Calcium Blood Test is important in evaluating muscle cramps and tetany.
