Test 1: Skeletons

Front 1

Primary and secondary function of skeletal system

Back 1

1. interactions with muscles involved with movement
2. support and protection

Front 2

Types of skeletons

Back 2

1. hdyrostatic
2. external
3. internal

Front 3

Describe hydrostatic skeleton

Back 3

1. has to be in fluid filled space
2. bulging; can't be compressed
3. advantage: allows fro motion
4. disadvantage: not a full range of motion
5. coelums, cavities

Front 4

Describe exoskeleton

Back 4

1. most have to be shed
2. joints allow more motion
3. during molting, animals stretch to make new cuticle layer larger

Front 5

Describe internal skeleton

Back 5

1. grows with organism
2. sponges, deutoerstomes

Front 6

Bone classifications

Back 6

1. long
2. short
3. flat
4. irregular

Front 7

Describe bone: long

Back 7

longer than they are wide
ex: humorous

Front 8

Describe bone: short

Back 8

1. more even in dimensions
2. box like

Front 9

Describe bone: flat

Back 9

1. sandwich like
ex: cranium, sternum

Front 10

Describe bone: irregular

Back 10

no specific shape b/c of projections
ex: vertebra

Front 11

Types of joints

Back 11

1. synarthrosis (not moveable)
2. amphiarthrosis (slight movable)
3. diarthrosis (ball and socket; synovial joints; hinged)

Front 12

Intramembranous bone formation

Back 12

1. occur in flat outer bones of skull
2. develop from non cartilage, connective tissue

Front 13

Endochondral bone development

Back 13

1. long bones
2. develop from cartilage
3. bone begins to ossify in diaphysis
4. growth between ossified regions
5. eventually, ossified regions fuse
