Scapula Anatomy Features Quiz

Scapula Anatomy: Key Features

• Acromion of Scapula:

  • The acromion is a bony projection on the scapula's superior aspect.
  • It articulates with the clavicle at the acromioclavicular joint.

• Coracoid Process of Scapula:

  • A hook-like structure located on the anterior side of the scapula.
  • Provides attachment points for muscles such as the pectoralis minor and the biceps brachii.

• Glenoid Cavity of Scapula:

  • A shallow depression that articulates with the head of the humerus, forming the glenohumeral (shoulder) joint.
  • Important for shoulder mobility due to its ball-and-socket structure.

• Lateral Border of Scapula:

  • The outer edge of the scapula, extends from the inferior angle to the glenoid cavity.
  • Provides attachment for muscles such as teres major and minor.

• Inferior Angle of Scapula:

  • The lowest point of the scapula, formed by the junction of the medial and lateral borders.
  • Serves as an important landmark for muscle attachment and can be used for determining scapular alignment.

• Medial Border of Scapula:

  • The inner edge of the scapula that runs parallel to the vertebral column.
  • Functions as an attachment site for muscles such as the serratus anterior and rhomboids.

• Subscapular Fossa of Scapula:

  • A broad, concave area on the anterior surface of the scapula.
  • Houses the subscapularis muscle, which plays a crucial role in shoulder internal rotation.

• Suprascapular Notch of Scapula:

  • A small indentation located at the superior border of the scapula.
  • Serves as a passage for the suprascapular nerve, crucial for the function of the shoulder girdle.
