The anterior triangle of the neck has several subdivisions. Innervation: The nerve supply, usually to a specific part of the body. The innervation of the cornea is dense.

Muscles of the Thoracic Wall Muscle Origin Insertion Action Primary Nerve Anterior Scalene Posterior Scalene Middle Scalene External intercostal Internal intercostal Describe the major blood vessels that both supply and drain the muscles described above. The insertion is the attachment to the movable bone where the force applied by muscle contraction causes a specific movement. Each muscle attachment is relative with respect to body movements. In two different muscles, these attachments may be reversed. Insertion. Insertion. 1. (Science: anatomy) The place of attachment, as of a muscle to the bone which it moves. 2. (Science: genetics) a rare nonreciprocal translocation involving three breaks in which a segment is removed from one chromosome and then inserted into a broken region of a nonhomologous chromosome. The Achilles tendon is a tough band of fibrous tissue that connects the calf muscles to the heel bone (calcaneus). The Achilles tendon is also called the calcaneal tendon. The gastrocnemius and soleus muscles (calf muscles) unite into one band of tissue, which becomes the Achilles tendon at the low end of the calf. The Achilles tendon then inserts into the calcaneus. Small sacs of fluid called bursae cushion the Achilles tendon at the heel. The Achilles tendon is the largest and strongest tendon in the body. When the calf muscles flex, the Achilles tendon pulls on the heel. The seven general types of skeletal muscle. The origin of a muscle is the bone, typically proximal, which has greater mass and is more stable during a contraction than a muscle's insertion. For example, with the latissimus dorsi muscle, the origin site is the torso, and the insertion is the arm. Normally the distal (arm) moves due to having less mass. The insertion of a muscle is the structure that it attaches to and tends to be moved by the contraction of the muscle. This may be a bone, a tendon or the subcutaneous dermal connective tissue. Insertions are usually connections of muscle via tendon to bone.
It is the place of attachment, as of a muscle to the bone which it moves.
