Moreover, what does the serratus posterior muscle do?

Function. The serratus posterior muscles contribute to the movement and stabilization of the vertebral column and the thorax. The serratus posterior superior elevates the ribs and thus supports the inspiration (accessory muscle of inspiration).

Also Know, how do you train the serratus posterior? First, you can do a few simple exercises at home that can get your serratus anterior into gear.

  1. Do shoulder blade protractions. Lean against a wall and press the backs of your palms and your elbows against it.
  2. Scapular pushups. Do scapular pushups.
  3. Wall exercises for the serratus anterior.

Moreover, where is the serratus posterior located?

The serratus posterior inferior muscle is located in the mid to lower back and forms a V-shape. It originates from the spinal processes (the points of the vertebrae closest to the skin) of vertebrae T11 to T12 and L1 to L2. It travels upward from its origin and inserts into the lower borders of ribs 9-12.

What causes serratus posterior pain?

The serratus posterior inferior muscle connects the lower ribs to four vertebrae in the low back. It is one of the muscles that aches and is stiff when you have slept on a mattress that is too soft. The pain from this muscle can be mistaken for kidney pain. Abdominal muscles frequently refer pain to the back.

What is serratus posterior superior innervated by?

The serratus posterior superior originates on the supraspinal ligament, the ligamentum nuchae, the spinous processes of the upper two to three thoracic vertebrae (T01–T03), as well as the seventh cervical vertebra. It inserts on the upper borders of ribs 2–5, and is innervated by intercostal nerves 2–5.

Is the erector spinae superficial or deep?

For the purposes of this chapter, the superficial erector spinae is the component that attaches to the thoracic spine and ribs (the thoracic erector spinae), whereas the deep erector spinae is that part attached to the transverse processes of the lumbar vertebrae (lumbar erector spinae).

How do you treat a pulled serratus posterior inferior muscle?

How is serratus anterior pain treated?

This results in "rounded shoulders," giving you a permanent slump. Now, the classic version of the pushup works your serratus anterior.

Can you tear your serratus anterior?

Since the serratus anterior attaches to the side of your rib cage, an injury to your ribs may also cause damage to the muscle. A rib fracture can cause the muscle tissue of the serratus to pull away, resulting in an avulsion fracture. This can be a painful injury and limit function of the serratus anterior.

What is the serratus posterior?

The serratus posterior muscles are two thin, superficial back muscles which lie above the intrinsic back musculature. The serratus posterior inferior muscle originates from the spinous processes of the T11 to T12 thoracic vertebrae and has its insertion on the four lower ribs.

What artery supplies the serratus posterior superior?

Serratus posterior superior muscle
Origin Nuchal ligament (or ligamentum nuchae) and the spinous processes of the vertebrae C7 through T3
Insertion The upper borders of the 2nd through 5th ribs
Artery Intercostal arteries
Nerve 2nd through 5th intercostal nerves

What nerve innervates the serratus posterior?

The ventral rami are the nerves that branch off the spinal cord anteriorly. The serratus posterior superior is innervated by the ventral rami of the T1-T5 vertebrae, while the serratus posterior inferior is innervated by the ventral rami of the T9-T12 vertebrae.

What are the intercostal muscles?

Intercostal muscles are several groups of muscles that run between the ribs, and help form and move the chest wall. The intercostal muscles are mainly involved in the mechanical aspect of breathing. These muscles help expand and shrink the size of the chest cavity to facilitate breathing.

Where do lats attach?

As the muscle fibers of the lats extend from the origin to the insertion point (the insertion for the lats is located on the inner aspect of your upper arm bone, just below the shoulder joint) they taper into a point.

What is serratus anterior?

The serratus anterior is a muscle that originates on the surface of the 1st to 8th ribs at the side of the chest and inserts along the entire anterior length of the medial border of the scapula. The serratus anterior acts to pull the scapula forward around the thorax.

What is thoracolumbar fascia?

The thoracolumbar fascia (lumbodorsal fascia or thoracodorsal fascia) is a deep investing membrane throughout most of the posterior thorax and abdomen although it is a thin fibrous lamina in the thoracic region. Above, it is continuous with a similar investing layer on the back of the neck—the nuchal fascia.

Which muscle inserts on the greater tubercle of the humerus?

Muscular attachment
The supraspinatus also originates on the spine of the scapula. It inserts on the greater tubercle of the humerus, and assists in abduction of the shoulder.

What is the insertion of the latissimus dorsi?

As the latissimus dorsi inserts into the floor of the intertubercular groove of the humerus it is surrounded by two major muscles. The teres major inserts medially on the medial lip of the intertubercular groove and the pectoralis major inserts laterally onto the lateral lip.

What are rhomboid muscles?

The rhomboid muscles are a group of muscles in your upper back. They're located on either side of your back, between your shoulder blades. Pain in the rhomboid muscles can be caused by a few things, such as: sprain: the stretching or tearing of ligaments, which are bands of thick tissue that connect bone to bone.
