Clinical Terms Related to the Muscular System

contracture (kon-trak'tilr) Condition in which there is great resistance to the stretching of a muscle. convulsion (kun-vul'shun) Series of involuntary contractions of various voluntary muscles. electromyography (e-lek"tro-mi-og'rah-fe) Technique for recording the electrical changes that occur in muscle tissues.

fibrillation (fi"bri-la'shun) Spontaneous contractions of individual muscle fibers, producing rapid and uncoordinated activity within a muscle.

fibrosis (fi-bro'sis) Degenerative disease in which connective tissue with many fibers replaces skeletal muscle tissue. fibrositis (fi"bro-si'tis) Inflammation of connective tissues with many fibers, especially in the muscle fascia. This disease is also called muscular rheumatism. muscular dystrophy (mus'ku-lar dis'tro-fe) Progressive muscle weakness and atrophy caused by deficient dystrophin protein. myalgia (mi-al'je-ah) Pain resulting from any muscular disease or disorder. myasthenia gravis (mi"as-the'ne-ah grav'is) Chronic disease characterized by muscles that are weak and easily fatigued. It results from the immune system's attack on neuromuscular junctions so that stimuli are not transmitted from motor neurons to muscle fibers. myokymia (mi"o-ki'me-ah) Persistent quivering of a muscle. myology (mi-ol'o-je) Study of muscles. myoma (mi-o'mah) Tumor composed of muscle tissue. myopathy (mi-op'ah-the) Any muscular disease. myositis (mi"o-si'tis) Inflammation of skeletal muscle tissue. myotomy (mi-ot'o-me) Cutting of muscle tissue. myotonia (mi"o-to'ne-ah) Prolonged muscular spasm. paralysis (pah-ral'i-sis) Loss of ability to move a body part. paresis (pah-re'sis) Partial or slight paralysis of the muscles. shin splints (shin' splints) Soreness on the front of the leg due to straining the anterior leg muscles, often as a result of walking up and down hills. torticollis (tor"ti-kol'is) Condition in which the neck muscles, such as the sternocleidomastoids, contract involuntarily. It is more commonly called wryneck.

Sensory Receptors Skeleton
Muscular System

Muscles provide the force for moving body parts.

Integumentary System Lymphatic System

The skin increases heat loss during skeletal muscle activity. Sensory receptors function in the reflex contol of skeletal muscles.

Muscle action pumps lymph through lymphatic vessels.

Muscle action pumps lymph through lymphatic vessels.

Skeletal System

Bones provide attachments that allow skeletal muscles to cause movement.

Bones provide attachments that allow skeletal muscles to cause movement.

Digestive System

Skeletal muscles are important in swallowing. The digestive system absorbs needed nutrients.

Nervous System

Neurons control muscle contractions.

Neurons control muscle contractions.

Respiratory System

Breathing depends on skeletal muscles. The lungs provide oxygen for body cells and eliminate carbon dioxide.

Endocrine System

Essentials of Human Physiology

Essentials of Human Physiology

This ebook provides an introductory explanation of the workings of the human body, with an effort to draw connections between the body systems and explain their interdependencies. A framework for the book is homeostasis and how the body maintains balance within each system. This is intended as a first introduction to physiology for a college-level course.
