What is the inferior angle of scapula?
One such landmark is the inferior angle of the scapula (IAS), which is said to correlate with the T7, T8, or T9 spinous process or spinal level, depending on the source. Gray’s Anatomy indicates that the IAS corresponds to the level of the ninth rib, which attaches to the spine at the T8–9 interspace.
Where is the inferior tip of the scapula?
The inferior angle of the scapula is the lowest part of the scapula and is covered by the latissimus dorsi muscle. It moves forwards round the chest when the arm is abducted. The inferior angle is formed by the union of the medial and lateral borders of the scapula.
What level is T7?
The T7 vertebra is the seventh thoracic vertebra, found in the middle of the chest between the seventh and eighth pairs of ribs. It plays important roles in the support of the spinal cord, ribcage, and muscles of the chest.
What level is the spine of the scapula at?
The root of the spine is on a level with the tip of the spinous process of the third thoracic vertebra.
What does scapular winging indicate?
If the winged scapula is the result of nerve damage, it can cause weakness in the muscles of your neck, shoulders, and arms. That weakness can make lifting, pulling, and pushing heavy objects hard. Scapular winging often affects your ability to raise your arm above your shoulder.
What is the tip of the scapula?
The scapula, also known as the shoulder blade, is a flat triangular bone located at the back of the trunk and resides over the posterior surface of ribs two to seven….Scapula.
| Borders | Superior, lateral and medial |
|---|---|
| Angles | Lateral, superior and inferior |
What happens if T7 is damaged?
In general, a patient with a fractured T7 would experience pain when moving, and have difficulty standing for long periods. Patients with associated rib fractures may sometimes even have pain with breathing (particularly when taking big breaths).
What does T7 control?
The nerves in the area of a vertebra control specific parts of the body. For example, the 7th cervical nerve (C7) in the neck area controls the triceps (the muscle in the upper arm), while the thoracic nerves (T2 through T7) control the chest muscles.
What does spine of scapula mean?
Medical Definition of spine of the scapula : a projecting triangular bony process on the dorsal surface of the scapula that divides it obliquely into the area of origin of parts of the supraspinatus and infraspinatus muscles and that terminates in the acromion.
Where is the base of the scapula?
The scapula is a flat, triangular-shaped bone (colloquially as the “shoulder blade”). It is located in the upper thoracic region on the dorsal surface of the rib cage. It connects with the humerus at the glenohumeral joint as well as the clavicle at the acromioclavicular joint to form the shoulder joint.
What are the upper and lower jugular groups?
This is called the upper jugular group. Drains the naso-/oro-/hypopharynx and parotid. This is called the middle jugular group. Drains the naso-/oro-/hypopharynx and larynx. This is called the lower jugular group.
Where is the 7th thoracic vertebrae?
T7 (7th Thoracic Vertebra) The T7 vertebra is the seventh thoracic vertebra, found in the middle of the chest between the seventh and eighth pairs of ribs.
What is the inferior angle of the scapula?
The inferior angle of the scapula is the lowest part of the scapula and is covered by the latissimus dorsi muscle. It moves forwards round the chest when the arm is abducted. The inferior angle is formed by the union of the medial and lateral borders of the scapula.
What muscles attach to the T7 vertebrae?
Many muscles that move the torso attach to the T7 vertebra. In particular, the multifidus and rotatores muscles attach to the transverse processes to rotate the spine. The trapezius and latissimus dorsi muscles of the back attach to the T7 at its spinous process. The T7 vertebra also plays an important role in the protection of the spinal cord.
