SKELETAL SYSTEM Flashcards
patellae is an example of _____ bone
sesamoid
extends from the coxofemoral (hip) joint to the stifle (the joint corresponding to the human knee)
femur
have well-developed articular processes to
accommodate the large range of motion of the neck o atlas is the first cervical vertebra; axis is the second cervical vertebra
cervical vertebrae
immediately distal to the carpus; single large bone in horse, while fused 3rd and 4th metacarpal bon in ox and sheep and called cannon bone; pig has 4
metacarpus
bone-producing cells; forms bone matrix
osteoblasts
rostral bone in swine, the soft tissue of the external nares
os rostri
a classification of bone wherein bones are relatively thin and expanded in two dimensions; diploe (spongy material that separates lamina externa from interna); chiefly for protection of vital organs.
flat bones
composed of multiple small bones; it corresponds to the human ankle
tarsus(hock)
contain the teeth of the upper dental
arcade (although the incisive bones lack teeth in ruminants)
maxillae and incisive bones
_______forms the ventrum of the bony thorax and gives attachment to the costal cartilages of the ribs as well as providing a bony origin for the pectoral muscles. Cranial extremity of the sternum is the manubrium; the middle portion is the body; and the caudal extremity is the xiphoid process
sternum
______ vertebrae form the bony basis for the tail
caudal
anatomical term for arm bone
humerus
presents numerous openings for passage of the
olfactory nerves (sense of smell)
ethmoid bone
the space surrounded by the cortex of a long bone
medullary cavity/ marrow cavity
in mammals, the radius is the larger of the two, although in birds it is smaller than the ulna; fused in equine and bovine, not fused in dogs and cats
radius and ulna
contain air spaces or sinuses that communicate with the atmosphere.
pneumatic bones
_______and digits of the pelvic limb are similar to the metacarpus and digits of the thoracic limb
metatarsus
the bone is composed of ___ organic framework of fibrous tissues and cells
1/3
number 1 to 5, depending on the species; In the horse, the proximal phalanx is also called the long pastern bone; the middle phalanx corresponds to the short pastern bone; and distal phalanx is also known as the coffin bone.
digits
a layer of hyaline cartilage within the metaphysis of an immature bone that separates the diaphysis from the epiphysis; area in which a bone can increase in length
epiphyseal cartilage
has cornual process (bony projections), except polled animals
frontal bone
refers to the bone stem cell
osteogenic cell
a classification of bone wherein bones are greater in one dimension than any other; function chiefly as levers and aid in support, locomotion, and prehension.
long bones
collagen and polysaccharides called _________, which contain chondroitin sulfate.
glycosaminoglycans
