A scapula in which the vertebral border below the level of the spine presents concavity instead of the normal convexity; the scaphoid type of scapula (Graves) is a scapula in which the vertebral border between the spine and the teres major process is either straight or tends toward concavity.
What is inferior angle of scapula?
Osteology. The main part of the scapula, the body, consists of a somewhat triangular-shaped flat blade, with an inferiorly pointing apex, referred to as the inferior angle as well as lateral and superior angles. The scapula is described as having superior, medial, and lateral borders.
How do you know if your scapula is left or right?
Right vs. Left–In order to determine if a scapula is right or left, orient it so the glenoid cavity (articulating surface) faces laterally (outward) and the spine is posterior (toward back) and superior (upper). The coracoid process should be anterior and superior.
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 borders of the scapula?
The scapula has three angles (superior/medial, lateral, inferior), three borders (medial, lateral/axillary, and superior), and two surfaces (ventral and dorsal). The scapula has three processes: the acromion, the spine, and the coracoid process.
What is Triangle auscultation?
The triangle of auscultation is a relative thinning of the musculature of the back, situated along the medial border of the scapula which allows for improved listening to the lungs.
What is the strongest part of scapula?
The medial border is a thin border and runs parallel to the vertebral column and is therefore often called the vertebral border. The lateral border is often called the axillary border as it runs superolaterally towards the apex of the axilla. It is the thickest and strongest of the three borders for muscle attachment.

What organ does the scapula protect?

What muscle holds the scapula down?
The serratus anterior is an important scapular stabilizing muscle. It originates from the first eight ribs and courses along the rib cage to insert along the anterior medial aspect of the scapula.
Is the acromion anterior or posterior?
On the anterior side, facing into the body, is a right-angled process called the coracoid process. While at the superior lateral edge of the scapula the glenoid cavity, which serves as the socket for the head of the humerus bone. The glenoid cavity always points laterally, while the spine and acromion are posterior.
What type of bone is the scapula?
flat triangular bone The scapula is a large, flat triangular bone with three processes called the acromion, spine and coracoid process . It forms the back portion of the shoulder girdle.
Where is the glenoid fossa?
shoulder joint The glenoid fossa is the socket of the shoulder joint. This part of the shoulder is a ball and socket joint. The head of the Humerus fits into the Glenoid fossa, though it is a shallow socket.
What is rhomboid major?
The rhomboid major is a skeletal muscle on the back that connects the scapula with the vertebrae of the spinal column. In human anatomy, it acts together with the rhomboid minor to keep the scapula pressed against thoracic wall and to retract the scapula toward the vertebral column.
What is in the triangular space?
The triangular space is an anatomic interval medial to the quadrangular space. Its borders are formed by the long head of the triceps laterally, the teres minor superiorly, and the teres major inferiorly. The circumflex scapular artery, a branch of the scapular artery, passes through the triangular space.
