Final answer:
The Serratus Anterior and Rhomboid Muscles attach to the scapula. Specifically, the Serratus Anterior attaches to its medial border, and the Rhomboid Muscles attach to the spine of the scapula and to the spinous processes of the thoracic vertebrae.
Step-by-step explanation:
The Serratus Anterior and the Rhomboid Muscles attach to the scapula. The Serratus Anterior primarily attaches to the medial border of the scapula and the Rhomboid Minor attaches to the spinous processes of the upper thoracic vertebrae and to the medial border of the scapula, specifically at the vertebral (medial) border.
The scapula is a triangular bone with several important landmarks. The coracoid process is a hook-like bony projection of the scapula that projects anteriorly and is shaped somewhat like a crow's beak. This is the attachment site for various muscles of the anterior chest and arm. On the other hand, the spinous process mentioned in options for the Rhomboid muscles refers not to a part of the scapula but to the protruding bony elements of thoracic vertebrae to which the rhomboid muscles connect.
