Lab 6: Appendicular Skeleton

Question 1

What are the components of the Pectoral Gridle? How can the right and left be distinguished?

Answer 1

1. Clavicle
   
   • First determined sternal and acromial(distal) end
   • Then look for subclavical groove (inferior)to determine R/L
2. Scapula
   
   • Determine superior angle and acromion(distal)
   • Determine R/L by looking at acromion position

Question 2

What is this structure? What are the three articulation points? Label the image (4)

Answer 2

Clavicle
Sternal articulates to Manibrium
Acromial articulates to acromium process
Conoid tubercle articulates to coronoid ligament

Question 3

What is this structure? What are the two articulation points? Label the image (13)

Answer 3

** Scapula**
Glenoid fossa articulates with Humeral head
Acromion articulates with clavicle

Question 4

What three bones are a part of the upper limb? How can R/L be determined?

Answer 4

1. Humerous
   
   • Identify coronoid fossa (ventral) or olecran fossa (dorsal)
   • The lateral epicondyle indicates which side is lateral
2. Radius
   
   • Head and neck are superior compared to radial styloid process
   • Radial styloid process is lateral to the ulna in anatomical position
3. Ulna
   
   • Identify Olecranon which is superior relative to the ulna styloid process
   • Ulna styloid process is medial to the radius

Question 5

What is this structure? Label the image (17).

Answer 5

Question 6

What are these two structures? Label the image (17).

Answer 6

Question 7

How can you tell if a hand is R/L

Answer 7

• Ulna will be on medial side
• The anterior view will have 4 bones along the bottom row

Question 8

What are the eight carpals?

Answer 8

1. Trapezium
2. Trapezoid
3. Capitate
4. Hamate
5. Scaphoid
6. Lunate
7. Triquetrum
8. Pisiform

Question 9

How are the metacarpals numbered? What a the the components of the phalanx?

Answer 9

• I->V thumb is I
• Proximal, middle, distal

Question 10

What bones make up the pelvic girdle?

Answer 10

• 2 Os coxae, 1 sacrum, 1 coccyx

Question 11

What is the pubic symphysis? Subpubic angle? Pelvic brim? What is the difference between the true and false pelvis? How are the male and female pelvis different?

Question 12

What are the structures in this image? Label them (28).

Answer 12

Question 13

What bones are a part of the lower limb? How can R/L be distinguished?

Answer 13

1. Patella
2. Femur
   
   • The fovea capitis is superior to the patellar surface
   • Intercondular fossa is dorsal
3. Tibia
   
   • Tibial tuberosity is located anterior
   • Medial malleolus is medial close to the inside of the ankle
4. Fibula
   
   • Locate the head and neck which are superior to the lateral malleolus
   • Lateral malleolus is lateral on the outside of the leg

Question 14

What are these two structures? Label them(15).

Answer 14

Question 15

What are these two structures? Label them (10).

Answer 15

Question 16

What are the three sections of the bones of the foot? What are the phalanx called? How are the metacarpals labeled?

Answer 16

• Tarsals, metatarsals, phalanx
• Distal, middle, and proximal
• I ->V big toe is I

Question 17

Label the Tarsal bones(7).
