Objective:
This study was aimed at evaluating the relationship between the dermatoglyphic characteristics and skeletal maturation by bone age in male adolescents aged 10 to 14.
Materials And Methods:
The adolescents were divided into 3 groups (early, normal and late) by the difference between their bone and chronological age;their dermatoglyphic characteristics were also verified. The chi-square test was used for comparing the groups.
Results:
The early teens'bone age showed greater potential for activities related to power and speed;normal and late teens hadgreater willingness for coordination and cyclic activities. Despite such tendencies, no statistically significant differences were found between the groups which may have been related to the low number of students in the early and normal groups.
Conclusions:
Although no significant differences were found, there was a tendency towards lower coordinative predisposition in advanced individuals which merits attention because this is an important physical quality regarding sport and performing everyday activities.

Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

Components of the Skeletal System
Bone, or osseous tissue, is a hard connective tissue that forms an internal support structure for the human body. Bones shield vulnerable organs and soft tissue from external forces. For example, the vertebral bones protect and support the spinal cord.

01:22Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
