Muscle Insertion Origin Insertion definitions
| # | Definition | Sets |
|---|---|---|
| 1 | sternocleidomastoid | 3 sets |
| 2 | origin is the attachment nearest the midline of the body (or least moveable bone) and the insertion is furthest from the body. | 3 sets |
| 3 | platysma | 2 sets |
| 4 | origin of the muscle is where the muscle is attached to the bone that moves relatively little and the insertion is where the muscle is attached to the bone that moves the most. | 2 sets |
| 5 | - from costal cartilages 7-12, thoracolumbar fascia, iliac crest, & lat. 1/3 of inguinal lig. - goes transversely - lowest fibers arch downward to form conjoint tendon - forms post. layer of rectus sheath | 1 set |
| 6 | muscle belly | 1 set |
| 7 | - from lower 8 ribs, goes inferomedially - post. fibers insert into iliac crest - broad external oblique aponeurosis intersecting at linea alba to form rectus sheath | 1 set |
| 8 | a) end of muscle attached to the more stationary part b) end attached to skeletal part that moves | 1 set |
| 9 | - from thoracolumbar fascia (post'ly), iliac crest, & lat. 1/2 of inguinal lig. - fibers go superomedially at right angle to external oblique - continues into internal oblique aponeurosis | 1 set |
| 10 | muscle terminology origin: where the _ begins • usually remains _ or is proximal to insertion _ : where the movement is - usually distal to the origin • if the muscle extends from a broad _ to a narrow tendon: _ = origin / tendon = insertion • if several tendons are at one end & only one at the other: multiple = origin / single = insertion | 1 set |
| 11 | -when the "anatomical" origin moves towards a (relatively) fixed insertion -eg chinup | 1 set |
| 12 | sternocleidmastoid | 1 set |
| 13 | biceps (two heads), triceps (three heads), quadriceps (four heads) | 1 set |
| 14 | thyroarytenoid (origin: lower portion of the thyroid cartliage...insertion: anterior artynoid cartilage) | 1 set |
| 15 | -also can be determined by proximal or distal or superior and inferior attachments, especially on limbs (nontraditional) -some muscles insert not on bone but on the fascia or tendon of another muscle or on collagen fibers of the dermis | 1 set |
| 16 | spinalis of erector spinae group originates and inserts at cervical, thoracic, and lumbar spinous processes | 1 set |
| 17 | attachment & insertion determines what moves [ named by convention; shape, etc] . | 1 set |
| 18 | tension is produced internally within sarcomeres' tension must be transmitted to bone by means of connective tissue and tendons before bone can be moved (series-elastic component) muscle typically attached to at least 2 different bones across a joint origin end of muscle attached to more stationary part of skeleton insertion end of muscle attached to skeletal part that moves | 1 set |
| 19 | insertion is pulled toward the origin, muscle can only pull never push, origin typically lies proximal to insertion, bulk of muscle lies proximal to joint crossed | 1 set |
| 20 | skeletal muscles shorten & pull on the bones they are attached to. origin is the bone that does not move when muscle shortens. insertion is the movable bone (some 2 joint muscles). belly is the fleshy portion of the muscle between attachment sites. | 1 set |
| 21 | -also can be determined by proximal or distal or superior and inferior attachments, especially on limbs -origins tend to be the more proximal attachment insertions tend to be the more distal attachment -some muscles insert not on bone but on the fascia or tendon of another muscle or on collagen fibers of the dermis -facial muscles insert in the dermis of the skin of the face and contribute to facial gestures when -contracted. | 1 set |
| 22 | skeletal mucles cross at least one moveable joint, one bone moves, other bone remains fixed, less movable attachment=origin (proximal), more movable=insertion (distal) | 1 set |
| 23 | isometric contraction | 1 set |
| 24 | origin and insertion - there is always a joint between the origin and insertion - origin is defined as the place where the fixed end attaches to a bone, cartilage, or connective tissue. *insertion is defined as the site where the movable end attaches to another structure. | 1 set |
| 25 | concentric contraction | 1 set |
