What are the most important muscles in the back?
The main muscles of the back include the latissimus dorsi (also known as the lats), rhomboids, trapezius, and erector spinae. The lat muscle, while located on the back side of the body, primarily affects movement of the shoulder joint and is responsible for moving the arms toward the sides and behind the body.
What are the 4 main back muscles?
Within this group of back muscles you will find the latissimus dorsi, the trapezius, levator scapulae and the rhomboids. These muscles are able to move the upper limb as they originate at the vertebral column and insert onto either the clavicle, scapula or humerus.
What are 5 muscles in your back?
They are divided into:
- Superficial extrinsic muscles of the back: trapezius, latissimus dorsi, rhomboid major, rhomboid minor, and levator scapulae.
- Intermediate extrinsic muscles of the back: serratus posterior superior and serratus posterior inferior muscles.
What is Multifidi?
Anatomical terms of muscle The multifidus (multifidus spinae : pl. multifidi ) muscle consists of a number of fleshy and tendinous fasciculi, which fill up the groove on either side of the spinous processes of the vertebrae, from the sacrum to the axis.
What are the deep back muscles?
The three deep muscles of the back include the semispinalis, multifidus, and rotatores. These muscles stabilize the vertebral column and also have a role in proprioception and balance. Moreover, these muscles help with the movements of the vertebral column and maintain posture.
What’s the biggest muscle in your back?
latissimus dorsi
The widest muscle in your body is the latissimus dorsi, also known as your lats. Your latissimus dorsi have a fan-like shape. They originate in the lower and middle portion of your back and attach on the inner aspect of your humerus (upper arm bone).
Which are 5 legitimate exercise that target the back muscles?

What is Intertransversarii?
Medical Definition of intertransversarii : a series of small muscles connecting the transverse processes of contiguous vertebrae and most highly developed in the neck.
What do the rotatores muscles do?
The rotatores (or rotatores spinae muscles, Latin: musculi rotatores) are deep muscles of the back located laterally along the spine. Each muscle extends between the transverse and spinous processes of the vertebrae. The main functions of the rotatores include stabilizing, rotating, and extending the spine.
What are the Transversospinalis muscles?
The transversospinalis muscle group is the deep layer of the intrinsic back muscles. These muscles lie between the transverse and spinous processes and are grouped by length of the fascicles, as well as region covered. The groups are rotatores, multifidus, and semispinalis.
What are the names of the muscles in the back?
Muscles found in the deep group include the spinotransversales, erector spinae (composed of the iliocostalis, longissimus and spinalis), the transversospinales, and the segmental muscles. The serratus posterior inferior and the serratus posterior superior compose the intermediate group of muscles.
Which is the weakest muscle in the back?
Weak muscles: 1 Thoracic erector spinae 2 Hip flexors 3 Quadriceps
Which is an intermediate muscle group in the back?
The two muscles which comprise intermediate muscle group are the serratus posterior inferior, and the serratus posterior superior. The serratus posterior inferior is located where the lumbar and thoracic regions join together.
Where are the erector spinae muscles located in the back?
These columns of muscles are further subdivided into three sub columns. The origin of the erector spinae is on the dorsal surface of the sacrum. The spinalis muscle, which is the most medial of the erector spinae muscles, inserts on the spines of the thoracic and upper lumbar vertebrae.
