PPT-DEVELOPMENT OF THE LIMBS

LG 1 Development of the Limb Bud Limb development is divided into four stages The bud stage initial outgrowth The paddle stage dorsoventral flattening The plate stage relative expansion of the distal end and .

Decreased number of bones. Appendicular Skeleton. The appendicular skeleton is made up of the bones of the limbs and their supporting elements (girdles) that connect them to the trunk. Pectoral girdles attach the upper limbs to the body trunk. EMBRYOLOGICAL DEVELOPMENT OF. THE SKELETAL SYSTEM . INTRODUCTION TO : The Embryology of the Skeletal System. The skeletal system develops from paraxial and lateral plate (somatic layer) mesoderm and from neural crest. Paraxial mesoderm forms a segmented series of tissue blocks on each side of the neural tube, known as . Chapter 9. Introduction. Transitions from water to land and from land to air have allowed for a great diversity of forms within the appendicular skeleton.. As with many other designs, form closely follows function..

Cerebral palsy (CP) is a neurodevelopmental impairment caused by a non-progressive lesion in a single or multiple locations in an immature brain. The lesion leads to persistent disorders of movements and posture that appear early in the infant's life (before 5 years). It is not a specific disease, but a group of neurological disorders of varied causes..
