Appendicular Skeleton Flashcards
The pectoral girdle consists of the what and is highly flexible, making it not very what?
Scapulae and clavicles, stable
The scapulae are attached to the axial skeleton by way of associated what and what?
Muscles and ligaments
Providing muscle attachment and acting as a brace for the scapula and arms is the function of the what?
Clavicle
The clavicle tends to what instead of dislocating due to the ligaments being strong and due to the s shape making it prone to fractures on the curves?
Break
The fossae on the scapulae have function?
Muscle attachment sites
The coracoid process of the scapula has what function?
Attachment point for the biceps muscle
The acromion of the scapula has what function?
Articulates with the acromial end of the clavicle
How many bones are in each of the upper arm?
30 bones
How many bones are in each of the hands if you include the wrist?
27 bones
The greater and lesser tubercles of the humerus have what function?
Muscle attachment sites
The deltoid tuberosity has what function?
Attachment site for deltoid muscle
The surgical neck and midshaft spiral fractures are common fractures in what bone?
Humerus
The lateral and medial epicondyles on the humerus have what function?
Attachment sites for forearm muscles
How are the radius and ulna connected? What does it do as well?
Interosseous membrane and keeps them at a fixed distance
The radial and ulnar styloid processes have what function?
Ligaments that anchor the wrist attach to them
FOOSH, or fall on outstreched hand, tends to fracture what and is more common in older females?
Distal radius
What carpal is the most fractured?
Scaphoid
What are the eight carpal bones?
Scaphoid, lunate, triquetrum, pisiform, trapezium, trapezoid, capitate, and hamate
What is the thumb called?
Pollex
The sacroiliac joint is very stable, making it what?
Not very free movement
What structure includes both the axial and appendicular skeletons?
Pelvis
What two hip bones make the obturator foramen?
Pubis and ischium
The os coxae is what three bones?
Pubis, ilium, and ischium
What are the sit bones?
Ischial tuberosities
Is the pelvic inlet or outlet more superior?
Inlet
The greater and lesser trochanters of the femur have what function?
Sites of muscle attachment
Is the false pelvis or true pelvis more superior?
False pelvis
What is the ridge along the posterior diaphysis of the femur bone?
Linea aspera
Does the fibula articulate with the femur at the knee?
No
What is the function of the linea aspera?
Sites for muscle attachments
What are the tibia and fibula connected by?
Interosseous membrane
What is the function of the patella?
Protect the knee joint and improves leverage of the quadriceps muscle
What projects to form the ankle bone?
Medial malleolus
What is the big toe called?
Hallux
What are the seven tarsal bones?
Calcaneus, talus, cuboid, navicular, and the medial, lateral, and intermediate cuneiform.
