Joints comprise broadly two categories:
*'''Synarthroses''' form joints that are relatively rigid
*'''Diarthroses''' form joints that are freely movable
=='''Fibrous Joints'''==
*Most occur in the skull: known as '''sutures'''
**Key in development: allow extension of individual bones during growth
**Gradually eliminated as ossification progresses
*'''Syndesmoses''': facing areas of two bones joined by connective tissue ligaments, very limited movement allowed
**Eg. Joints of the metacarpus in the horse
*'''Gomphosis''': attachment of tooth to bone within its socket
=='''Cartilaginous Joints'''==
*AKA '''Synchondroses''': eg. joints between epiphyses and diaphyses of juvenile long bones
