scapula Flashcards
scapula
What is the primary function of the scapula?
The primary function of the scapula is to connect the humerus (upper arm bone) with the clavicle (collarbone) and provide attachment points for muscles.
True or False: The scapula is commonly referred to as the shoulder blade.
True
Fill in the blank: The scapula articulates with the __________ at the glenoid cavity.
humerus
Which two bones does the scapula connect?
The scapula connects the humerus and the clavicle.
What are the three main borders of the scapula?
The medial (vertebral) border, lateral (axillary) border, and superior border.
Multiple choice: Which of the following is NOT a process of the scapula? A) Acromion B) Coracoid C) Olecranon D) Glenoid
C) Olecranon
What is the significance of the acromion process?
The acromion process serves as an attachment point for the clavicle and is involved in shoulder mobility.
True or False: The scapula is a flat bone.
True
What muscle group is primarily attached to the scapula?
The rotator cuff muscles.
Fill in the blank: The inferior angle of the scapula is important for the movement of the __________.
shoulder
What is the glenoid cavity?
The glenoid cavity is a shallow socket on the scapula that articulates with the head of the humerus.
Multiple choice: Which of the following motions does the scapula NOT perform? A) Elevation B) Depression C) Flexion D) Rotation
C) Flexion
What is the relationship between the scapula and the shoulder joint?
The scapula forms part of the shoulder joint by providing a socket for the humerus.
True or False: The scapula has a direct connection to the ribcage.
False
What are the two surfaces of the scapula called?
The costal (anterior) surface and the dorsal (posterior) surface.
Fill in the blank: The scapula is located on the __________ side of the body.
posterior
Which ligament connects the scapula to the clavicle?
The acromioclavicular ligament.
Multiple choice: Which part of the scapula is involved in shoulder abduction? A) Acromion B) Glenoid C) Coracoid D) Spine
B) Glenoid
What role does the scapula play in arm elevation?
The scapula provides a stable base for the arm to elevate by rotating upward.
True or False: The scapula is a paired structure, meaning there are two scapulae in the body.
True
What is the primary blood supply to the scapula?
The suprascapular artery and the circumflex scapular artery.
Fill in the blank: The scapula is part of the __________ girdle.
pectoral
What is the clinical significance of scapular winging?
Scapular winging indicates weakness or injury to the muscles that stabilize the scapula, particularly the serratus anterior.
Multiple choice: Which muscle is NOT attached to the scapula? A) Deltoid B) Trapezius C) Biceps brachii D) Pectoralis major
D) Pectoralis major
What is the role of the serratus anterior muscle in relation to the scapula?
The serratus anterior stabilizes the scapula against the thoracic wall and allows for upward rotation.
