Anatomy III part 2

Question 1

m.tibialis cranialis

Answer 1

O: lateral condyle and crest of tibia
I: medial side on os tarsi mt. I and mt. I-II

Question 2

m.peroneus longus

Answer 2

O: tibia´s lateral condyle, head of fibula, lateral collateral ligament
I: os tari 4-5, extend to all metatarsal bones plantar surface

Question 3

m.peroneus brevis

Answer 3

O: laterally on distal third of fibula
I: base Mt. V

Question 4

m.extensor digitorum longus

Answer 4

O: fossa extensoria on lateral femoral condyle
I: distal phalanx digits II-V

Question 5

m.extensor digitorum lateralis

Answer 5

O: proximal third of fibula
I: digit V distal phalanx

Question 6

m.extensor digiti I.hallucis longus

Answer 6

O: middle third of fibula
I: radiates into fascia over join of digit II

Question 7

m. gastocnemius

Answer 7

O: medaial and later supracondylar tuberosity of femur, (caput medial/caput lateral)
I: tuber calcanei (as part of tuber calcanei tendon)

Question 8

Tendo calcaneus communis

Answer 8

3 parts:

• tendo m.gastrocnemii (m.gastrocnemius)
• tendo m. plantaris (ex. m.extensor dig.suoerficiale)
• tendo accessorius (lateral: m. biceps femoris, medial: m.gracillis and m.semitendinosus

as tendon widen (galea calcanea)

Question 9

m.flexor dig. superficiale

Answer 9

O: fossa supracondylare of femur, partly fused with m. gastrocnemii
I: its plantar tendon turns from medial to lateral direction around common calcanea tendon , on the surface of tuber calcanei it makes a cap galea calcanea, then finally attaches to middle phalanx digits II-V on plantar surface

Question 10

M. popliteus

Answer 10

O: fossa m.poplitei, lateral femoral condyle
I: twist caudally under lig. collaterals lateral, then insert caudally on proximal part of tibia, on line m.poplitei

Question 11

m. flexor digitorum profundus

Answer 11

O: lateral part: proximal caudal half of fibula, proximal caudolateral border of tibia and from interosseous membrane. Medial: stars cause-proximally from tibia, below tarsus the two parts unite.
I: plantar surface of distal phalanx dig II-V

Question 12

tarsal flexor and digital extensor nerves

Answer 12

Common fibular nerve, last terminating branches of Sciatic nerve, passes over lateral head of m.gstrocnemii, divide into deep and superficial

Question 13

superficial fibular nerve

Answer 13

lies caudally to the fibulas longus muscle, forms the dorsal common digital nerves innervating the paw

Question 14

Deep fibular nerve

Answer 14

runs with cranial tibial artery, lie between the cranial tibial muscle and the long digital extensor muscle, forms the dorsal common digital nerve, innervating the paw

Question 15

tarsal extensor and digital flexor veins

Answer 15

cranial tibial artery (branch of popliteal artery), runs with deep fibular nerve, continues past the hook and dorsal pedal artery

Question 16

tarsal extensors and digital flexors vessels:

Answer 16

• popliteal artery, terminates as cranial tibial and caudal tibial artery
• caudal tibial artery, running with tibial nerve
• saphenous artery, cranial and caudal branch

Question 17

tarsal extensor and digital flexors nerves:

Answer 17

n.tibiales, one of the terminating branches of the sciatic nerve, passes between the 2 heads of m.gastronemii, divides into medial and lateral plantar nerves

Question 18

N.phrenicus

Answer 18

C5,C6,C7, left and right nerve, crosses the heart, innervates the diaphragm

Question 19

N.vagus

Answer 19

runs into thorax gives of recurrent laryngeal nerve, crosses the aorta and divides (just caudal to the heart) into dorsal and ventral ramus. these rani unite as they perforate the diaphragm: left and right dorsal rami

Question 20

Abdominal wall and its nerves

Answer 20

n. costoabdominalis (th13)
n. iliohypogastricus cran (L1)
n. iliohypogastricus (L2)
n. ilioinguinalis (L2-L3)
n. genitofemoralis (L3-L4) —> m.obliquus internus abd

Colon transverse 
Colon descendens 
Rectum

Answer 21

• a.caecalis
• r.colicus, a.colica dex
• a.colica media
• a.colica sin, colica media
• a.rectalis cran
