Muscle Origin Insertion definitions
| # | Definition | Sets |
|---|---|---|
| 1 | origin is the attachment nearest the midline of the body (or least moveable bone) and the insertion is furthest from the body. | 3 sets |
| 2 | sternocleidomastoid | 2 sets |
| 3 | biceps (two heads), triceps (three heads), quadriceps (four heads) | 1 set |
| 4 | 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 |
| 5 | sternocleidmastoid | 1 set |
| 6 | -when the "anatomical" origin moves towards a (relatively) fixed insertion -eg chinup | 1 set |
| 7 | -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 |
| 8 | 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 |
| 9 | 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. | 1 set |
| 10 | 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 |
| 11 | 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 |
| 12 | a) end of muscle attached to the more stationary part b) end attached to skeletal part that moves | 1 set |
