| Question | Answer |
|---|---|
| smooth muscle | muscles found all over the body such as eyes, lungs, stomach, intestines, urinary bladder |
| skeletal muscle | voluntary movement of the bones so the animal can move around |
| cardiac muscle | the heart |
| what is muscle used for? | movement, contraction, protection, maintaining strength |
| tendon | muscle to bone |
| ligament | bone to bone |
| origin of muscle | area that moves the least at attached sight of muscle (proximal) |
| insertion of muscle | area that moves the most at attached sight of muscle (distal) |
| agonist | moves the muscle |
| antagonist | pulls against the muscle |
| what is one of the best healing tissues in the body? | bone |
| what is crucial for healing bone? | time, alignment, immobilization |
| external fixations | splints and casts |
| internal fixations | wires, pines, screws, plates |
| what effects the speed of healing? | species, age, physical condition, size |
| osteoblasts | healing/growing bone tissue |
| osteoclasts | eat away bone tissue |
| callus | osteoblasts from the area of forming healing tissue |
| smaller callus means... | less movement between fractured fragments |
| bigger callus means... | more movement between fractured fragments |
| True or false: smaller callus heals quicker | True |
| navicular disease | when bone begins to undergo chronic, painful degeneration |
| the distal sesamoid bone is also called the... | navicular bone |
| True or false: navicular disease is normally 100% curable | False |
| What can be done to help navicular disease? | hoof triming, shoeing, and drug therapy |
| hip dysplasia | the abnormal looseness or laxity of the hip joints |
| What can cause hip dysplasia? | overnutrition leading to rapid growth, exercise, genetic factors |
| True or false: Hip dysplasia can be hereditery? | True |
| what would be proper treatment for hip dysplasia? | weight reduction, restriction of exercise, antiinflammatory drugs, variety of surgical procedures |
| True or false: Calcium helps prevent clotting | True |
| Main function of bones are…. | Support, leverage, protection, blood cell formation |
| Hematophoiesis | produces red blood cells |
| Where is hematophoiesis located? | the spongy bone |
| Examples of irregular bone | vertebra, sesamoids, patella |
| What is long bone made of? | Cancellous covered by compact bone |
| What is short bone made of? | Spongy covered by thin compact |
| What is flat bone made of? | Spongy covered by compact bone |
| Articular surface | where bones come in contact with each other to form joints |
| Diaphysis | mid portion of long bone |
| Epiphysis | ends of long bone |
| Periosteum | layer around bone (fibrous membrane ) |
| Endosteum | lines medullary cavity |
| Epiphyseal plate | growth plate in long bones |
| True or false: An epiphyseal line means the bone is still growing | False |
| True or false: in a developing fetus cartiledge comes before bone | True |
| Ossification | hardening of bone |
| Fracture | Any kind of break in the bone |
| Simple fracture | a break in the bone contained within the tissue |
| Compound fracture | a break in the bone protruding through the skin |
| Fissured fracture | incomplete break (crack) |
| Greenstick fracture | incomplete break on one side |
| Transverse fracture | complete break, straight through the bone |
| Comminuted fracture | complete break, numerous bone fragments |
| Oblique fracture | complete break diagonally |
| Slab | a piece of bone is pulled off |
| Exostoses | excess bone formation |
| Non-union | when bones don't come together |
| arthro- | refers to joints |
| Example of an immoveable joints | skull |
| Slighty moveable joints | vertebra and mandible |
| Freely moveable | Stifle joint, hip joint |
| True or false: Joint capsule keeps two ends of bones held together | True |
| Inter synovial membrane | Secrets fluid |
| Outer synovial membrane | lubricates and provides nutrients from cartiledge |
| Arthritis | inflammation of joint |
| Luxation | usually through trauma, is a dislocated joint |
| Subluxation | partial dislocation |
| Joint ill | infection through umbilical cord |
| Intra capsular ligaments | ligaments in the joint |
| Extra capsular ligaments | ligaments outside the joint |
| Ankylosis | Fussion at the end of a bone and is no longer moveable |
