Question 2

Patella is shattered, what structures will be compromised? (What structures are in this region)

Answer 2

Rectus femoris mm, vastus lateralis mm, vastus medialis mm, vastus intermedius mm, articularis genu mm,

superior/middle/inferior medial genicular arteries, superior inferior/genicular arteries, posterior tibial recurrent aa, anterior tibial recurrent aa, popliteal aa

Question 3

Upper shaft/neck of the femur is fractured what blood structures will be damaged?

Answer 3

Medial femoral circumflex aa, lateral femoral circumflex aa (ascending branch, transverse branch, descending branch)

Question 4

Fall backward and fractured sacrum and coccyx. What structures might be affected?

Answer 4

Glute max mm, piriformis mm ( originate from sacrum and coccyx)
Sacrotuberous/sacrospinal ligament (originate from sacrum)
Everything that exits the greater and lesser sciatic foramen since the above ligaments create the foramens (superior gluteal VAN, Inferior gluteal VAN, pudendal n, internal pudendal aa, sciatic nn, posterior cutaneous nerve of the thigh, piriformis mm, obturator internus mm, n to obturator internous + superior gemellus, n to quadratus femoris and inferior gemellus)

Question 5

Shunt blood from the heart to the R Dorsi Pettis aa if R Femoral aa and R profundus femoris arteries have blockage.

Answer 5

Ascending aorta
Arch of aorta
Descending thoracic aorta
Descending abdominal aorta
R Common illiac aa (everything below this will be on the right side of the body)
Internal iliac aa
Superior gluteal aa
Ascending branch of lateral femoral circumflex aa
Transverse branch of lateral femoral circumflex aa
Descending branch of lateral femoral circumflex aa
Superior lateral genicular aa
Popliteal aa
Anterior tibial aa

(More than one way to get here, if you used the same try another path!)

Question 6

What structures will be gone if your foot is cut off just above your medial/lateral malleolus? and identify if they’re on the bottom or top of your foot. (Blood and Nerves only)

Answer 6

Bottom: medial and lateral plantar nerves, medial and lateral plantar aa, plantar arterial arch, x5 plantar digital aa, posterior tibial aa

Top: Deep fibular nn, superficial fibular nn, dorsal petis aa, dorsal arterial arch, x5 dorsal digital aa, anterior tibial aa

Question 7

Jimmy got kicked in his pubic bone and experienced a fracture near the pubic crest and ischiopubic ramus; what actions might be affected? ( justify it with a muscle that originates there and creates that action)

Answer 7

Hip Adduction (adductor brevis/longus/magnus/gracilis/obturator externus originate here)
Hip Flexion (adductor brevis/longus/gracilis)
Hip IR (Gracilis)
Hip Extension (Adductor magnus)
Knee Flexion (gracilis)
Knee Internal Rotation (gracilis)

Question 8

Name all the cranial nerves that exit the superior orbital fissure of the sphenoid bone.

Answer 8

Cranial Nerve III Oculomotor
Cranial Nerve IV Throclear
Cranial Nerve V Trigeminal Nerve (Ophtolmic divison)
Cranial Nerve VI Abducens

Question 9

Name all the Cranial Nerves that exit the jugular formaen and what two bones make up the jugular foramen.

Answer 9

Cranial Nerve IX Glossopharyngeal
Cranial Nerve V Vagus
Cranial Nerve XI Spinal Accessory

Temporal and Occibital bones make up the jugular foramen

Question 10

Eye Socket was damaged in a hunting accident, what bones would be damaged?

Answer 10

Sphenoid, Ethmoid, Lacrimal, Frontal, Maxillary, Palatine, Zygomatic.

Question 11

Describe the Sciatic Nerves components as it divides into the ccommon fibular and tibial nerve and as the common fibular nerve divides into the superficial and deep fibular nerves.

Answer 11

Sciatic Full SAM but only MA expressed to innerveate posterior thigh muscles (semitendinosus, semimembranosus, biceps femoris long head via tibial division and biceps femoris short head via common fibular division)
At popliteal region it physically divides into tibial nerve and common fibular. Tibial nerve is MA with silent SA through posterior aspect of leg and divides into the medial and plantar nerves which are both active SAM at the soles of feet expressing both SA and MA as they innervate the plantar muscles of the feet and provide SA components to the lateral and medial portions of the feet.
Common fibular SA at knee divides into deep fibular and superficial fibular, both are full SAM deep fibular is MA with anterior leg muscles and SA between toes 1 and 2 and superficial fibular is MA with lateral leg muscles and SA from about half of anterior lateral leg going down to the dorsum of the foot.
