What part of the spine controls the shoulders?
The C4 dermatome covers parts of the neck, shoulders, and upper part of arms. C5 helps control the deltoids (which form the rounded contours of the shoulders) and the biceps (which allow bending of the elbow and rotation of the forearm). The C5 dermatome covers the outer part of the upper arm down to about the elbow.
What causes pain between the shoulder blade and spine?
Poor posture, injury, or problems with the spine can all lead to upper back pain. A common cause of pain between the shoulder blades is muscle strain. Treatments for mild upper back pain include stretching exercises and pain relievers. Some cases of pain between the shoulder blades are preventable.
Is the scapula connected to the spine?

What connects your shoulder blade to your back?
It works to allow a lot of range of motion in forward flexion (arms in front), abduction (arms to the sides), adduction (arms across the body) and extension (arms reaching back). The acromioclavicular joint connects the clavicle to the acromion, which is part of the shoulder blade or scapula.
Can sleeping wrong cause shoulder blade pain?
Can Sleeping Wrong Cause Shoulder Blade Pain? Our posture affects us during all hours of the day, including when we sleep. Certain sleeping positions can put extra strain on the shoulder muscles, resulting in soreness and stiffness.
What is the main function of the scapula?
The scapula is an important bone in the function of the shoulder joint. It engages in 6 types of motion, which allow for full-functional upper extremity movement including protraction, retraction, elevation, depression, upward rotation, and downward rotation.
What are the 3 processes of the scapula?
The scapula has three processes: the acromion, the spine, and the coracoid process. Muscle attachments to these landmarks are covered in the “Muscles” section. The ventral surface of the scapula abuts the thoracic rib cage and has a large concavity called the subscapular fossa where the subscapularis attaches.
Is your shoulder connected to your back?
The shoulder blade makes up the back part of the shoulder girdle (see illustration). It is a flat, triangular bone. The back muscles that connect to the head of the upper arm bone are attached here. The shoulder blade is divided into a small upper and larger lower surface by a ridge called the scapular spine.
