What is the medial border of the scapula?
Medial border or margin (Margo medialis) is the medial edge of the scapula and is also called the vetebral border. This area is an attachment point for the rhomboid major, rhomboid minor and serratus anterior muscles.
What is medial border?
Anatomical Parts The medial border (vertebral border) is the longest of the three, and extends from the medial to the inferior angle. It is arched, intermediate in thickness between the superior and the axillary borders, and the portion of it above the spine forms an obtuse angle with the part below.
What is another name for the medial border of the scapula?
The medial border (also called the vertebral border or medial margin) is the longest of the three borders, and extends from the superior angle to the inferior angle. In animals it is referred to as the dorsal border.
What is the lateral border of the scapula?
The lateral border (axillary border) is the thickest of the three borders of the scapula. It begins above at the lower margin of the glenoid cavity, and inclines obliquely downward and backward to the inferior angle. Immediately below the glenoid cavity is a rough impression, the infraglenoid tuberosity,about 2.5 cm.
What is the medial angle?
The medial angle because of its anatomical location was named “spinovertebral” angle, owing to its position at the scapulae spine, and located in medial proximity to the vertebra column. Conclusion. The medial angle (now referred to as the spinovertebral angle) of the right side of the scapula is wider than the left.
How do you identify the medial and lateral borders of the scapula?
Borders and angles Like any triangle, the scapula consists of three borders: superior, lateral and medial. The superior border is the shortest and thinnest border of the three. The medial border is a thin border and runs parallel to the vertebral column and is therefore often called the vertebral border.
What structure is most medial?
Medial group The median nucleus is the most medial of the three structures. The medial dorsal nucleus is superior to the medial ventral nucleus, but both are lateral to the median nucleus and medial to the internal medullary lamina.
What muscles attach to the medial border?
Four muscles attaches to the medial border. At the full extent of the anterior lip is the insertion of serratus anterior, the posterior lip gives insertion to the levator scapulae (uppermost), rhomboid minor (middle), and the rhomboid major (lower middle) [2, 4, 5].
What muscle inserts on the medial border of the scapula?
The rhomboideus major muscle was attached on the medial border of the scapula opposite the infraspinous fossa and could be traced to the dorsal surface of the bone just above the inferior angle. All the three muscles overlapped the costal surface of the serratus anterior fascia for about three centimeters.
What are scapular angles called?
Scapula
| Borders | Superior, lateral and medial |
|---|---|
| Angles | Lateral, superior and inferior |
| Surfaces | Anterior: subscapular fossa Posterior: supraspinous fossa, spine, infraspinous fossa |
| Processes | Coracoid, acromion |
What is example of medial?
Medial means toward the middle or center. It is the opposite of lateral. The term is used to describe general positions of body parts. For example, the chest is medial to the arm.
What is the difference between lateral and medial?
Overview. A lateral orientation is a position away from the midline of the body. For instance, the arms are lateral to the chest, and the ears are lateral to the head. A medial orientation is a position toward the midline of the body.
