Question 1

differentiate the axial and appendicular skeleton

Answer 1

Question 1

where is the sternum found?

Answer 1

in the thoracic cage

Question 2

identify the clavicle and the components of the sternum

Answer 2

Question 3

give the functions of the components of the sternum

Answer 3

Question 4

label the manubrium, body, xiphoid process, jugular notch, and sternal angle

Answer 4

Question 5

give the functions of the jugular notch and sternal angle

Answer 5

Question 6

what aspect of the sternum articulates with the clavicle?

Answer 6

The manubrium of the sternum articulates with the clavicle at the clavicular notches, located on the superior sides of the manubrium.
This forms the sternoclavicular joint, which connects the axial skeleton to the appendicular skeleton.

Question 7

why would identifying the location of the xyphoid process be important for health care providers?

Answer 7

Identifying the location of the xiphoid process is important for healthcare providers because it serves as a landmark to avoid injury during procedures like CPR (cardiopulmonary resuscitation). Proper hand placement for chest compressions is positioned above the xiphoid process to prevent fracturing it, which could damage underlying organs like the liver or diaphragm.

Question 8

identify the scapula, humerus, radius and ulna

Answer 8

Question 9

identify the scapula, humerus, radius and ulna (anterior view)

Answer 9

Question 10

give the function of the scapula, humerus, radius and ulna

Answer 10

Question 11

identify head, tubercle, articular facets

Answer 11

Question 12

identify the femur, patella, tibia, fibula

Answer 12

Question 13

identify acetabulum, iliac crest and anterior superior iliac spine

Answer 13

Question 14

find head, greater and lesser trochanter, neck, lateral and medial epicondyles and lateral and medial condyles

Answer 14

Question 15

find medial/lateral condyles, tibial, and medial malleolus

Answer 15

Question 16

fill in the blanks

Answer 16

Question 17

fill in the blanks

Answer 17

Question 18

what kind of cartilage comprises the articular cartilage

Answer 18

The articular cartilage is composed of hyaline cartilage. This type of cartilage is smooth and resilient, providing a low-friction surface to facilitate joint movement and cushioning the bones to absorb shock during activities

Question 19

what are the ligaments of the acromioclavicular joints

Answer 19

Question 20

identify the Acromioclavicular Ligament, Coracoclavicular Ligaments, Coracoacromial Ligament.

Answer 20

Question 21

differentiate separated and dislocated shoulders

Answer 21

Question 22

fill in the blank

Answer 22

Question 23

which position is the hip the most vulnerable to dislocation and why

Answer 23

Question 24

just gonna leave these pics here

Answer 24

Question 25

what is the major polysaccharide carbohydrate that provides the slippery aspect of synovial fluid

Answer 25

The major polysaccharide carbohydrate that provides the slippery aspect of synovial fluid is hyaluronic acid (also called hyaluronan). It is a key component of synovial fluid, contributing to its viscosity and lubrication, which reduces friction between articulating joints and helps protect the cartilage during movement.

Question 26

where does the MCL attach and what role does it play in knee function

Answer 26

Question 27

what type of cartilage can be found inside the joint

Answer 27

Question 28

does articular cartilage have blood supply of innervation. how does that affect the process of tissue repair

Answer 28
