Skeletal (W3.3.2) Flashcards
Poll-evil
inflammation of the atlanal bursa found between nuchal and atlas
Fistulous Withers
inflammation of the supraspinous bursa, found over spinous process of first thoracic vertebrae
Thoracic Vertebrae by species
Dog/cat - 13
Horse - 18
Bovine - 13
Anticlinical Vertebrae
vertebrae where spinous process is straight up; spines cranial to this are inclined caudally, spines caudal to this are inclined cranial
Dogs T10, cat T11, Horse T16, Cow T13
Ventral longitudinal ligament
prevents over extension of the vertebrae
Dorsal longitudinal ligament
prevents hyperflexion of the vertebrae
Intervertebral disc
fibrocartilage between vertebrae
Annulus fibrosus
thin dorsally and thick ventrally; of the vertebral disc
Nucleus pulposus
semifluid center, absorbs shock; of the vertebral disc
Rupture of intervertebral disc
degeneration and rupture of the annulus fibrous dorsally so nucleus pulposus bulges or explodes into spinal canal
Causes pressure on spinal cord and pain or paralysis
Thoracolumbar usually T11-L2; with T13-L1 most common
Hemilaminectomies
Removal of right or left dorsal vertebral arch to relieve spinal cord pressure
Disc Fenestration
removal of remaining nucleus pulposus from ruptureed disc
Wobblers
horse (ataxia) or dog (ataxia-paralysis) with cervical vertebral instability
Lumbar Vertebrae by species
Dog/cat - 7
Horse - 6
Bovine - 6
Sacrum
Fused bones of the vertebrae
wings - lateral part articulating with hip at sacroiliac joint
Sacrum by species
Dog/cat - 3
Horse/bovine - 5
Coocygeal
Caudal vertebrae (tail) number and appearance vary widely even within the same species
Thorax
Sternum, ribs and vertebrae, protects thoracic organs
True ribs
attach to sternum directly
False ribs
attach via costal arch to sternum
Floating ribs
last rib in dog, not attached to sternum
Head of rib
articulates with vertebrae
Intercostal space
between adjacent ribs
Costal Cartilage
hyaline cartilage that connects rib to sternum or costal arch or ends free
