Thus, these definitions contain the main difference between origin and insertion of muscles. The tables on the following pages detail the origin, insertion and action of some of the major muscles in the body. Origin: Anterior Inferior Iliac Spine (AIIS). a section of genetic material that is inserted into an existing gene sequence. An even smaller number of muscles are named after the parts of the body where they start and end their origin and insertion.
The moveable end of the muscle that attaches to the bone being pulled is called the muscle's insertion, and the end of the muscle attached to a fixed (stabilized) bone is called the origin..

The action, or particular movement of a muscle, can be described relative to the joint or the body part moved. But the insertion is the end where it shows movement along with the muscle moves. The muscle extends obliquely in an inferolateral direction, to insert into the base of the medial end of the . Insertion: Inner surface of the medial cuneiform and 1st metatarsal. For example, the abductor muscles of the legs spread the legs away from the midline and away from one another. Conventionally, a muscle origin describes the attachment of a muscle on the more stable bone. In anatomy, an insertion describes the point of attachment in a muscle where more movement occurs. Anatomy The point or mode of attachment of a skeletal muscle to the bone or other body part that it moves. 3. in genetics, a rare nonreciprocal type of translocation in which a segment is removed from one chromosome and then inserted into a broken region of a nonhomologous chromosome. And again, as a geneticist, when we think of an insertion, we think of a piece of DNA, and that can be small or large, being stuck in at a place where it really doesn't belong. Insertion really means that something has been stuck in there. Flexion is a movement, generally in the sagittal plane, that decrease the angle of the joint and brings two bones closer together; it is a type of hinge joints, but it is also common at ball-and-socket joints.
In seemingly unrelated parts of the body (referred pain) Treatment focuses on relieving pain and getting tight fascia and muscle fibers to relax. The scalene muscles are three paired muscles (anterior, middle and posterior), located in the lateral aspect of the neck.
Lesson Summary. Insertion refers to the distal end of attachment of a muscle to a bone that will be moved by the muscle. Eccentric contraction refers to muscle action in which the muscle force yields to the imposed load.

Access Origin and Insertion To see a muscle's attachment points, select the muscle from the model. where the muscle attaches to immovable bone. The origin is the fixed attachment, while the insertion moves with contraction. The key difference between origin and insertion is that origin is the bone attachment at the stationary end of the muscle while insertion is the bone attachment to the mobile end of the muscle.. A muscular tissue mainly comprises of all the contractile tissues of the body including skeletal, cardiac, and smooth muscles.Muscles are a type of connective tissue important for the motions in organisms.
