Objectives
- Name the components of a somite and the
adult derivatives of each component.
- Give examples of sites of (a) endochondral
and (b) intramembranous ossification and to
compare these two processes (consult Histology
Manual).
- Enumerate the general times (a) of formation
of primary and (b) of formation of secondary
ossification centres, and (c) of fusion of such
centres with each other. (Refer to Introductory
Anatomy notes).
- Briefly summarise the development of the
limbs.
- Describe the developmental aberrations
responsible for the following malformations:
selected growth plate disorders; congenital
dislocation of the hip; scoliosis;
arthrogryposis; and limb reduction
deformities.

Learning activities
- Identify the component parts of a somite in
a 6-7mm pig embryo (from 6mm pig
microfiche).
- List the derivatives of a thoracic
somite.
- Examine slides 9, 10, 12, 56 and 57 and
identify the type of ossification that is
present or has occurred at various sites in each
slide.
