Study Notes
Muscular System
- Objectives: This chapter covers terminology related to muscle structure and function, terminology for physical examination of muscles, tests for diagnosing muscular disorders, and disorders of the muscular system.
Muscle Structure and Function
-
Key to Terminology: Knowing the medical prefix for muscle (myo-) from the Greek word for muscle (mys) is essential. Combining this prefix with other words creates terms like myology (muscle study), myocardium (heart muscle), and myositis (inflammation of voluntary muscles).
-
Muscle Functions: Muscles have three main functions: supporting the body, enabling movement, and generating body heat. They are also crucial components of internal organs (e.g., heart, lungs, uterus, intestines).
Muscle Makeup
- Muscle Fibers: Muscle tissue cells are often long, slender, and thread-like, which are called muscle fibers
- Fascia: Connective tissue bundles, encloses muscle fibers together.
Terminology: Combining Forms
| Combining Form | Meaning | Terminology | Meaning |
|---|---|---|---|
| Fasci/o | Fascia (sheaths enveloping muscles) | fascioplasty | Surgical repair of the fascia |
| Fibr/o | Fibrous connective tissue | fibromyalgia | Pain in connective tissues & muscles |
| My/o | Muscle | myalgia | Pain in the muscles |
| Myocardi/o | Heart muscle | myocardial | Pertaining to heart muscle |
| Ten/o | Tendon | tenodynia | Pain in the tendon |
Prefixes
| Prefix | Meaning | Terminology | Meaning |
|---|---|---|---|
| Bi- | Two | biceps | Muscles with two heads |
| Dys- | Pain | dyskinesia | Pain in movement |
| Tri- | Three | triceps | Muscles with three heads |
| Poly- | Many | polymyositis | Inflammation in many muscles |
| Ton/o | Tendon | hypotonia | Decreased muscle tone |
| Tendon/o | Tendon | tendonitis | Inflammation of the tendon |
Muscular Disorders
- Myopathy: Any disease of skeletal muscles.
- Myoclonus: A spasm of a muscle; sudden, brief, involuntary twitching or jerking of a muscle or group of muscles. (myo- muscle; clonus spasm)
- Myelomalacia: Muscle softening, a rare condition that leads to spinal cord softening. (myelo- spinal cord; malakia softening)
- Myoatrophy (Muscle Wasting): Shrinking of muscles due to inactivity, illness, or injury.
- Myosclerosis: Muscle hardening.
- Myobradia: Slow reaction time of a muscle to a stimulus, likely due to tissue damage or death.
Diagnostic Procedures
- Electromyography (EMG): Records the electrical activity of skeletal muscles using needle or surface electrodes; helps detect neuromuscular issues.
- Range of Motion Testing: Evaluates the range of joint mobility and muscle strength.
- CT Scan: Uses multiple X-rays at different angles to image body structures.
- Magnetic Resonance Imaging (MRI): Uses a powerful magnetic field and radio waves to create detailed images of body tissues; useful for diagnosing muscle disease.
Injuries
- Sprain: Complete or incomplete tear of ligaments surrounding a joint.
- Strain: Injury to a muscle or tendinous attachment.
- Epicondylitis (Tennis Elbow): Inflammation of tendons in the forearm at their attachment to the humerus.
- Tendinitis: Painful inflammation of tendons; inflammation can affect any muscle or tendon.
Terminology Definitions (from Exercises)
- Myalgia: Pain in muscles.
- Myoatrophy: Muscle wasting.
- Myobradia: Slow reaction of muscle.
- Electromyography: Recording electrical activity of a muscle.
- Tendinitis: Inflammation of tendons.
- Epicondylitis: Inflammation of tendons in the forearm.
