What is the longest muscle of the human body? What is the largest muscle of the upper back?

Answer 1

Longest: Sartorius
Largest (UPPER Back):Trapezius

Longest: The Sartorius, which primarily performs hip flexion, abduction, and knee flexion, is a long, thin muscle that extends from the outside of the upper thigh down and across the leg to the inside of the knee. https://tutor.hix.ai

The largest muscles in the back are called the Latissimus Dorsi, or Lats for short. These large, fan-shaped muscles can generate force in a variety of body positions, such as leaning back or straight up and down, and all angles in between.

The Lats have fibers that run in a fan down the pelvic girdle and down the vertebral column. They are attached to the upper end of the humerus.

The Trapezius muscle, also known as the "trap," is a long, trapezoid-shaped muscle that originates at the base of the skull, travels down the spine, and attaches to the scapulae in the middle back. It runs down the upper portion of the spinal cord.

Pull is produced by the angles of the trapezius fibers in three directions: up, down, and inward toward the body's centerline. The upper, middle, and lower traps are the three distinct muscle sections that carry out these actions.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
