LIMB DEVELOPMENT Flashcards
WHAT ARE AER
APICAL ECTODERMAL RIDGES
WHAT TO APICAL ECTODERMAL RIDGES FORM
LIMB BUDS
WHEN DO AER FORM
4TH WEEK, LOWER 4 DAYS LATER THAN UPPER
WHAT WEEKS DOES LIMB DEVELOPMENT TAKE PLACE IN
4-8
WHAT SPINAL LEVELS ARE THE UPPER LIMB BUDS VISIBLE AT
C5-8
WHAT SPINAL LEVEL ARE THE LOWER LIMB BUDS VISIBLE AT
L3-5
WHAT DAY DO UPPER LIMB BUDS OCCUR
24
WHAT DAY TO LOWER LIMB BUDS OCCUR
28
WHAT FACTORS CAN AFFECT LIMB DEVELOPMENT
GENETIC, ENVIRONMENTAL, MECHANICAL
WHAT IS OSSIFICATION
BONE DEVELOPMENT
WHAT ARE THE TWO PROCESSES OF BONE DEVELOPMENT
INTRAMEMBRANOUS AND ENDOCHONDRAL
WHAT IS INRAMEMBRANOUS OSSIFICATION
OSSIFICATION OF FLAT BONES (SKULL AND FACE)
WHAT IS ENDOCHONDRAL OSSIFICATION
OSSIFICAITON OF LONG SHORT AND IRREGULAR BONES
WHAT DOES THE MESENCHYME DO
FORMS A MEMBRANOUS TEMPLATE FOR THE FUTURE BONE
WHAT IS THE DIFFERENCE IN THE ROLE OF MESENCHYMES BETWEEN ENDOCHONDRAL AND INTRAMEMBRANOUS OSSIFICATION
ENDOCHONDRAL = MESENCHYMES DIFFERENTIATE INTO CHONDROBLASTS
INTRAMEMBRANOUS = DIFFERENTIATE INTO OSTEOBLASTS
