Fascia | is a band of connective tissue that envelops, separates, or binds together muscles or groups of muscles (plural, fasciae or fascias). Fascia is flexible to allow muscle movements. |
Tendon | is a narrow band of nonelastic, dense, fibrous connective tissue that attaches a muscle to a bone. Do not confuse tendons with ligaments, which are bands of fibrous tissue that form joints by connecting one bone to another bone |
Patellar tendon | attaches muscles to the bottom of the patella |
Achilles tendon | attaches the gastrocnemius muscle (the major muscle of the calf of the leg) to the heel bone |
Aponeurosis | a sheet-like fibrous connective tissue, which resembles a flattened tendon that serves as a fascia to bind muscles together or as a means of connecting muscle to bone (plural, aponeuroses). |
skeletal muscle | are attached to the bones of the skeleton and make body motions possiblealso known as voluntary muscles because we have conscious (voluntary) control over these muscles. In Skeletal muscles are also known as striated muscles because under a microscope, the dark and light bands in the muscle fibers create a striped appearance. |
smooth muscle | are located in the walls of internal organs such as the digestive tract, blood vessels, and ducts leading from gland Their function is to move and control the flow of fluids through these structures. In Smooth muscles are also known as involuntary muscles because they are under the control of the autonomic nervous system and are not under voluntary controSmooth muscles are also known as unstriated muscles. This is because they do not have the dark and light bands that produce the striped appearance seen in striated muscles. In Smooth muscles are also known as visceral muscles because they are found in hollow structures such as those of the digestive and urinary systems. Visceral means relating to the internal organs. These muscles are found in large internal organs, with the exception of the heart |
Myocardial muscle | Myocardial muscle is like striated skeletal muscle in appearance, but is similar to smooth muscle in that its action is involuntary. It is the constant contraction and relaxation of the myocardial muscle that causes the heartbeat |
muscle innervation | is the stimulation of a muscle by an impulse transmitted by a motor nerve. Motor nerves enable the brain to stimulate a muscle to contract. When the stimulation stops, the muscle relaxes. This information controls the body’s voluntary muscular contractions |
antagonistic | refers to working in opposition to each other |
contraction | tightening of a muscleit becomes shorter and thicker, causing the belly (center) of the muscle to enlarge |
relaxation | occurs when a muscle returns to its original form. As the muscle relaxes, it becomes longer and thinner, and the belly is no longer enlarged. |
Abduction | is the movement of a limb | (arm or leg) away from the midline of the body |
Abductor | is a muscle that | moves a body part away from the midline. |
Adduction | is the movement of a limb (arm or leg) toward the midline of the body |
Adductor | is a muscle that | moves a body part toward the midline |
Elevation | is the act of raising or lifting a body part. For example, the elevation of the levator anguli oris muscles of the face raises the corners of the mouth into a smile |
