• Living and dynamic organs
• Responsive to many nutritional, hormonal, and physical factors
• Develop and grow by ossification
• Gaps of non-ossified tissue between bones form sutures
o Doliocephalic: 270 ex: whippet
o Mesaticephalic: 235 ex: rotweiler
o Brachycephalic: 200 ex: Persian and Bulldog
Skeleton
• Support and storage
o Axial: skull, vertebrae, ribcage, sternum
▪ Skull = 30 bones
▪ Dog has 42 teeth, cat has 30
▪ Baby teeth come in at 6 weeks and are replaced by 6 months
▪ Vertebral Column = 33+ bones (Cervical 7, thoracic 13, lumbar 7, sacral 3, caudal
3-23) protects spinal cord and supports skull
▪ Ribcage = 13 pairs and protects main organs

▪ Carpus(wrist) and Manus(foot): first digit = dew claw
• Tendons: muscles to bone
• Ligaments: bone to bone
Coverings and Linings of the Body
• Protection: skin, scales, claws
• Chemical Exchange: lining of digestive tract, lungs, kidneys, thermoregulation
• Secretions: endocrine and exocrine
