Muscular System

Across
Muscles that facilitate prime movers by performing the same movements at the same time
Broad, flat tendon that attaches muscle to bone, muscle to muscle, or muscle to skin
Basic unit of contraction; lined end to end in repeating compartments along entire length of each myofibril; a single myofibril may contain as many as 15000!
Group of disorders involving spasms of the sternocleidomastoid and possibly other neck muscles
Parallel muscle fibers; arranged along the long axis of bone and are usually taperd at both ends or are spindle shaped
Folds in the sarcolemma, part of the neuromuscular junction
Acid formed as the end product of anaerobic glycolysis
Continued partial contraction of skeletal muscles
When deep fascia forms a cord, anchoring muscles to bone
Chronic inflammation of a thick band of fascia located on the foot; most common orthopedic complaint relating to foot
Fascia that extends from superficial fascia and surrounds muscles, as well as their fasciculi and individual fibers
When muscles or tendons become overstretched or torn
Universal unit of energy in the cell
muscle that helps move substances in the cardiovascular and gastrointestinal systems
Type 1 muscle fibers; they contain large amounts of myoglobin and mitochondria and have more blood capillaries; contract more slowly for longer periods of time and able to resist the fatigue of sustained activity
Characterized by localized tenderness, widespread pain, joint stiffness, fatigue, non-refreshing sleep, and mood problems
Create the reverse action of prime movers and synergists; usually lie on opposite side of moving joint
Muscle cells with a distinct thread like shape
Down
General term for tissue that cover, protect, separate, and bind body organs and structures
Tendon organs that detect tension or pull; activated when tension exceeds a certain threshold and triggers lengthening reaction
Covering of the muscle fiber or cell. Equivalent to a cell membrane
Muscles are generating force while their length remains the same and movement does not occur
Neuron responsible for sending impulses which stimulate muscle fibers to contract
Skeletal muscles are the most metabolically active structures in the body and produce a significant amount of heat. This mechanism is important for maintaining body temperature;
The intercellular fluid within muscle fibers; equivalent of cytoplasm
A single motor neuron and all muscle fibers; may branch off and connect to 2 or up to 2000 individual muscle fibers
Molecules strung together resembling a twisted double stand of beads and contain binding sites for myosin
Extending the muscle to its fullest length
Each muscle fiber contains thousands of slender strands, they lay side by side and run the leach of each muscle fiber
Muscle fibers that contract more quickly and for shorter periods of time
Abbreviation; characterized by presence of trigger points and muscular pain, can produce both pain and referred pain when pressed
Principal neurotransmitter involved in muscle contraction
When excited, the ends of the muscles and contractile units within the muscles pull toward its center
Pain along the medial tibia, often bilateral and common among people who participate in sports/exercise that involve running and jumping
Muscle cells ability to return to their original shape after shortening and lengthening
Specialized synergists that stabilize joints or help maintain posture so prime movers can exert their action
Second stage of glycolysis where oxygen is used to produce energy; process creates the equivalent of 36 ATP molecules
Most common type of muscle contraction; muscles generate force and cause muscle length to change
Some examples of this muscle fiber are the latissimus dorsi, levator scapulae, and pectoralis major
