Common Word Roots for Muscular System

Review Flashcards

Through the use of this flashcard review list, you will get a more detailed grasp of the root words and combining forms associated with the muscular system.

Check out the quiz version of this flashcard if you want to see how much you remember.

#1 fasci/o

fasci/o is a combining form that refers to "fascia".

Fascia is a thin layer of connective tissue that encloses each organ, nerve fiber, muscle, blood vessel and bone in its proper position. In addition to providing internal structure, fascia has nerves that give it almost the same sensitivity as skin. It tends to tighten up when stressed.

#2 flex/o

flex/o is a combining form that refers to "bend".

Bending is the process of turning from straight to curved or angular.

#3 in/o, fibr/o

in/o or fibr/o is a combining form that refers to "fiber".

In the body, fiber pertains to tissue composed of strands of long cells, for example, the fibers of muscles and nerves.

#4 kin/e, kinesi/o, kinet/o

kin/e, kinesi/o or kinet/o is a combining form that refers to "movement".

In simple terms, movement is the act of moving or the change of position.

#5 leiomy/o

leiomy/o is a combining form that refers to "smooth visceral muscle".

Smooth (visceral) muscle fibers are found in the walls of hollow internal organs (including the liver, pancreas, and intestines), with the exception of the heart. Visceral muscle allows organs to contract and move substances. A visceral muscle is controlled by the brain's unconscious part, making it an involuntary muscle.

#6 my/o, myos/o, muscul/o

my/o, myos/o or muscul/o is a combining form that refers to "muscle".

Muscle refers to the tissue of the body that is composed of clusters of cells that undergo contractions and relaxation to generate movement. Three types of muscle exist in the body: skeletal (striated), smooth, and cardiac.

Examples of Medical Terms Containing my/o, myos/o or muscul/o

Myalgia: my ( "muscle") + -algia ( "pain")

Definition: Pain in the muscles.


Myocardium: my/o ( "muscle") + cardi ( "heart") + -um ( "pertaining to")

Definition: The muscular tissue of the heart.


Myositis: my/o ( "muscle") + -itis ( "inflammation")

Definition: Inflammation of the muscles, which can cause pain, weakness, and difficulty moving.


Myotomy: my/o ( "muscle") + -tomy ( "incision")

Definition: Surgical incision of a muscle.


Myofibril: my/o ( "muscle") + fibril ( "small fiber")

Definition: Small fibers within muscle fibers that are responsible for muscle contraction.


Myosin: myos ( "muscle") + -in ( "substance")

Definition: A protein that is found in muscle fibers and is responsible for muscle contraction.


Myogenic: my/o ( "muscle") + -genic ( "pertaining to the origin")

Definition: Pertaining to the origin of muscle tissue.


Myopathy: my/o ( "muscle") + -pathy ( "disease")

Definition: A disease or disorder of the muscle.


Myotome: my/o ( "muscle") + -tome ( "section")

Definition: A section of muscle tissue.


Musculature: muscul ( "muscle") + -ature ( "structure")

Definition: The structure of the muscles.


Musculoskeletal: muscul/o ( "muscle") + skel ( "bone") + -al ( "pertaining to")

Definition: Pertaining to the muscles and bones.


Musculotendinous: muscul/o ( "muscle") + tendin/o ( "tendons") + -us ( "pertaining to")

Definition: Pertaining to the muscle and tendons.


Musculoligamentous: muscul/o ( "muscle") + ligament ( "ligaments") + -ous ( "pertaining to")

Definition: Pertaining to the muscle and ligaments.

#7 myocardi/o

myocardi/o is a combining form that refers to "cardiac muscle".

Myocardium (cardiac muscle) constitutes the thick middle layer of the heart. Only the heart contains cardiac muscle tissue, which pumps blood through the circulatory system through rhythmic contractions. Unlike skeletal muscle, cardiac muscle is characterized by rhythmic contractions and cannot be controlled voluntarily.

#8 rhabdomy/o

rhabdomy/o is a combining form that refers to "skeletal or striated muscle".

Skeletal muscles are the muscles that attach to the bones and enable the body to execute a variety of functions and movements. Skeletal muscles are voluntary, which means an individual can control their activity.

#9 sarc/o

sarc/o is a combining form that refers to "connective tissue; soft" or "flesh".

The connective tissues in the body support, protect, and give structure to other tissues and organs. Connective tissue is also responsible for storing fat, transporting nutrients and other materials between tissues and organs, and restoring damaged tissue. There are four types of connective tissue: blood, bone, cartilage, and connective tissue proper (such as fat).

#10 tens/o

tens/o is a combining form that refers to "stretch; strain".

Tension is the process or act of stretching; the condition of being strained or stretched.

#11 ton/o

ton/o is a combining form that refers to "tone".

During rest, muscle tone refers to the continuous and passive contraction of the muscle or the muscle's resistance to passive stretching.Through the use of this flashcard review list, you will get a more detailed grasp of the root words and combining forms associated with the muscular system.

#12 ten/o, tendin/o, tend/o

ten/o, tendin/o or tend/o is a combining form that refers to "tendon". 

Tendons are fibrous connective tissues that bind muscles to bone as well as connecting muscles to specific structures such as the eyeballs. Tendons help to facilitate the movement of the bone or structure they are attached to.
