Can’t crack the clue? Discover the mystery back muscle!

Certainly! The answer to the crossword clue ‘Back muscle, informally’ is ‘LAT’, which is short for the Latissimus Dorsi muscle. The Latissimus Dorsi is one of the largest muscles in the human body and is located on either side of the back. It is often referred to in an informal setting as the “lats”.

The Latissimus Dorsi muscle has a broad and triangular shape, covering a significant portion of the back. It originates from several points on the spine, lower back, and pelvis, then stretches upward towards the shoulder. It inserts into the upper arm bone, specifically the humerus.

This muscle is responsible for various movements in our upper body. It plays a crucial role in pulling movements, such as rowing, rock climbing, and even swimming. When the Latissimus Dorsi contracts, it pulls the arms towards the body, assisting in movements like pull-ups, chin-ups, and even when performing a deadlift.

Identifying the Latissimus Dorsi muscle can be helpful not only when solving crossword puzzles but also for understanding our own body and its capabilities. So, the abbreviated term ‘LAT’ is often used informally when referring to this back muscle.
