Anatomy and physiology- skeletal system Flashcards
what are the functions of the skeletal system
-provides form and support for the body
-muscular attachment (locomotion)
-protection (ie. brain, skull, heart, lungs)
-produces RBC
what does the skeletal system consist of
bones, cartilage, teeth and joints
what is the outer layer of bones made of
composed of tricalcium phosphate and well as collagen and chondroitin sulphate
what nutrients can be added to livestock diet to reduce leg weakness and lameness
adequate levels of calcium, phosphorus and vitamin D
what is the inner cor of bone made of
soft tissue known as bone marrow
what are some common sources of feed stuff in livestock diet that can be added to prevent lameness
limestone (CaCO3), dicalcium phosphate, and alfalfa
what are the two types of marrow
-yellow marrow, which is predominantly fat
-red marrow, which functions in blood cell and platelet formation
what are permpartum diets in dairy cattle designed for
increasing Ca absorption
decreasing renal Ca. excretion
increase bone mobilization
what are the types of vertebra
cervical (neck)
thoracic (attached to ribs)
lumbar (tbone)
sacral (sacrum)
coccygeal (tail)
what are the parts of the skeleton
-axial skeleton: skull, vertebral column, rib cage
-appendicular skeleton: pectoral limb (front), pelvic limb (rear)
