identify 5-10
- Last lumbar vertebra (L7)

- Acromion
- Greater tubercle
- Olecrenon
- Lateral epicondyle
identify 11-16

what is the vertebral formula of a goat
C7 ,T13 ,L6 ,S4 ,Cd 10-14
ID 23,24,25
- External abdominal oblique m.
- Fascia of abdominal mm.
- Tuber coxae
ID 26-30
- Deep gluteal m.
- Tensor fascia lata
- Gluteobiceps m., superficial
gluteal portion.
28’. Gluteobiceps m., biceps femoris
m. portion - Semitendinosus m.
- Long digital extensor m
ID 6,7,8
- Trapezius m., cervical portion
- Trapezius m. thoracic portion
- Deltoideus m
ID 1,3,4
**one is on the cheek, I know its hard to see
- Masseter m.
- Brachiocephalicus m.
- Sternomandibularis m.
what are the digits the goat walks on
3 and 4!
identify 1-6
ones to ID are the ones Dr.Nadar specifically talked about during lecture
1.scapular cartilage
2. infraspinous fossa
3.humerus
4. olecranon tuber
5. olecranon
6. ulna
identify 7-12
ones to ID are the ones Dr.Nadar specifically talked about during lecture
7.radius
8. lateral epicondyle of humerus
9. deltoid tubersity of humerus
10. greater tubercle of humerus
11. spine of scapula
12. supraspinous fossa
How is the ulna of a goat similar to a horse
it reduces in size as you get more distal
what is unique about metacarpal 3 and 4 of a goat
they are fused, make up the cannon bone
**remember they are even-toed animals!
T/F the scapular cartilage is larger than it is in a dog/cat
true
- metacarpal bone 3 and 4
- proximal phalanx
- middle phalanx
- distal phalanx
DO NOT PUT P1,P2,P3
what does it mean that goats are artiodactyla
Typically, they are ungulates which bear weight equally on two of their five toes
what are some animals of the artiodactyla classification
caprine
ovine
bovine
swine
are horses artiodactyla
NO they are Perissodactyla (odd-toed)
how many proximal sesamoid bones are there
2 per digit (4 in total)
how many distal sesamoid bones are there
1 per digit (2 total)
identify the muscles of the antebrachium of a caprine
craniolateral group antebrachial muscles
how many extensors are there? flexors?
craniolateral group; 3 extensor mm. & 1 flexor m
OIA’s for muscles
Digit 3 and 4, which is medial and lateral
3= medial
4= lateral
1= proximal phalanx
2= middle phalanx
3= distal phalanx
NOT P1,P2,P3
How is the goat like to dog when it comes to the triceps
the triceps has 4 heads instead of the traditional 3
flexor carpi ulnaris m.
Common digital extensor tendon has ____ components
two!
Lateral & Medial portion.
Common digital extensor tendon
has 2 components:
Lateral portion divides & inserts
@ ____________________
extensor processes of both distal phalanges # 3 & # 4
what is the purpose of the interdigital sinus in goats
The gland secretes an oily or waxy substance with a distinct odor, which may help goats identify each other and mark their territory
what happens if the interdigital sinus gets blocked or infected
lameness
The circled bony prominence is the remnant of what bone
fibula
tensor fascia lata muscle
middle gluteal muscle
T/F Ruminants lack a separate superficial gluteal muscle
true!
what 2 muscles make up the gluteobiceps m
Biceps femoris m. & superficial gluteal m
Semitendinosus muscle
Semimembranous muscle
Cranial gluteal nerve
what is significant about these nerves in a dairy cow
these are what we block during a C-section
what is this
Rocky mountain goat
how many TOTAL sesamoid bones are there in the manus of the bovine
6 total (3 per digit)
