There also are bands of fibrous connective tissue—the ligaments and the tendons—in intimate relationship with the parts of the skeleton. %%EOF OSSIFICATION . 0000002916 00000 n Organisms with an endoskeleton are supported by a hard, mineralized skeletal system that resides inside the body. 0000002397 00000 n terrestrial vertebrates is to provide the main propulsive force for the animal. ��5��m`�+V��6�� &�������|��d� H ��z�����d��yϙ�9�3n7� � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � �D�|������5������k�6:i�#��*u%���7ɛж_5���qM��Af! From the perspective of comparative morphology, including paleontology, it has been suggested that two lineages of skeletal systems—the endoskeleton and exoskeleton—have succeeded in vertebrate evolution (Figure 1, Table 1) [7,11].
