Chapter 8: The Appendicular Skeleton Flashcards
(55 cards)
What structures comprise the appendicular skeleton?
The pectoral girdles, upper limbs, pelvic girdle, and lower limbs
The _______ and _________ on the inferior surface are the attachment sites for muscles and ligaments of the shoulder
conoid tubercule and costal tuberosity
The anterior or costal surface of the scapula that is smooth and concave is called the
Subscapular fossa
Name the bones of the pectoral girdles
Each of the two pectoral girdles consists of a clavicle (collarbone) and a scapula (shoulder blade)
Each arm articulates with the trunk at the pectoral girdle
Which bone articulates with the scapula at the glenoid cavity?
The humerus
The point of the elbow is called the
Olecranon
With which carpal bones does metacarpal IV articulate?
The hamate and capitate
The concave socket that articulates with the head of the femur is called the
Acetabulum
The articulation where the two pubic bones are attached to a middle pad of fibrocartilage is called
The pubic symphysis
What is the correct term for the opening formed by the pubis and the ischium?
The obturator foramen
Which three bones make up a hip bone?
The ilium, ischium, and pubis
Which of the leg bones does not articulate with the femur?
The fibula
Which fibular process gives lateral stability to the ankle?
Lateral malleolus
A fracture where the lateral malleolus of the fibula and the medial malleolus of the tibia are broken is called
Pott’s fracture
What landmark is found on the posterior surface of the scapula?
Spine
Identify the socket of the shoulder joint
Glenoid fossa
Identify the region of the scapula that articulates with the clavicle
Acromion process
Which region of the scapula is found on the anterior surface?
Subscapular fossa
Identify the process on the scapula that does not articulate with another bone.
Coracoid process (projects anteriorly and laterally)
Stress fractures due to running primarily affect the metatarsals. Which bone does NOT articulate with the metatarsals?
Navicular
The inferior surface of the clavicle has a projection called the:
Conoid tubercule
Identify the bone that articulates with the clavicle laterally
Scapula
Identify the depression found on the posterior surface of the distal humerus
Olecranon fossa
Identify the primary region of the ulna that forms the hinge joint with the humerus
Trochlear notch
