What is the lattisimus dorsi?

Answer 1

The latissimus dorsi is the broadest muscle of the back. The origin of a muscle is the point of fixed attachment to the bone. Because of it's triangular shape, the multi-points of origin are: the bottom 6 thoracic vertebrae, the last 3-4 ribs, the thoracolumbar fascia, the back third of the lip of hip and a small bit attaches to the bottom angle of the shoulder blade.

Answer 2

the lattisimus dorsi is a muscle which goes from the lower back towards the humerus (upper arm bone). the muscle is used to bring the arms towards the body, rotate them and draw them back and inwards towards the body. you can strengthen your lattisimus dorsi by doing:

• chin ups
• lat pull downs on weight machined
• push ups

Answer 3

The latissimus dorsi (plural: latissimi dorsi), meaning 'broadest muscle of the back' (Latin latus meaning 'broad', latissimus meaning 'broadest' and dorsummeaning the back), is the larger, flat, dorso-lateral muscle on the trunk, posterior to the arm, and partly covered by the trapezius on its median dorsal region.

Answer 4

The latissimus dorsi occupies most of the posterior torso. Being the muscle with the greatest surface area of the body, it's only other neighbours (at a superficial level) are the trapezius and infraspinatus muscles.

Answer 5

So, having said that, if you don't understand...

When the Latissimus Dorsi muscle contracts it will cause the upper arm to be sucked into the side of your body, rotate the arm in toward the mid-line of the body and pull the arm down to your side if your arm was flexed out in front of you, say to 90˚. Hope this helps.
