OSTEO COMPARA Flashcards
APPENDICULAR (92 cards)
Four regions of the forelimb.
Shoulder, Upper arm(brachium), Forearm(antebrachium), Manus (Carpals)
Spine fades out distally. Trapezius tubercle
(spinal tuber/deltoid tubercle) present. What animal?
Horse
What animal when scapula bone is distinctly triangular. Spine sinuous,
dividing lateral surface into unequal fossae.
Ox/Sheep
What animal if prominent trapezius tubercle is
overhanging infraspinous fossa.
Pig
When the spine bisects lateral surface and distinct acromion. What animal?
Dog
Determination of Side of Scapula: (2 parts for cranial and lateral)
Spine is lateral, tuber scapulae is cranial
It is absent in horse and pig
Acromion
A bony enlargement of the scapular spine only found in horse and pig, although poorly developed in cat and ox
Spinal Tuber
A narrow band in the dog; broad thin structure in horse, ruminants and pigs
Scapular Cartilage
A caudal projection of acromion; distal end of spine can be called the acromion or hamate (L.hooked) process
Suprahamate process
Forms a join with the scapula in birds and higher primates
Clavicle
Clavicle is represented by (?), a connective tissue band within the braciocephalicus muscle in quadrupeds.
Clavicular tendon
a separate, non-articulating bone only seen radiographically in this animal
Cat
A rudimentary structure embedded in the brachiocephalic muscle, rarely seen radiographically in this animal.
Dog
Clavicleis absent in these animals
Horse and ruminants
(Supraglenoid tubercle in carnivores fuse by 8 months of age)
(Supraglenoid tubercle and cranial glenoid cavity fuse in a year)
(Dorsal border of scapula which fuses at 3 years)
Secondary ossification centers
Can be mistaken for a bone in the esophagus on lateral radiographs in cats.
Clavicle
When bicipital groove is divided by a ridge, what animal.
Horse
Has a massive lateral tuberosity that overhangs bicipital groove
Ox/Sheep
Has a lateral tuberosity that almost converts bicipital groove into foramen
Pigs
Has a single lateral tuberosity. Coronoid olecranon fossae communicate through supratrochlear foramen.
Dogs
Determination of Side in Humerus
Crest-Lateral, Head-Posterior,Medial
Hole between the olecranon and radial fossa found in (?) and sometimes in pigs; nothing passes through it
Supratrochlear fossa, in Dogs
