History of body

Introduction

The history of human body falls under the study of human anatomy is the science -practical and morphological -dedicated mainly to the study of macroscopic structures of the body human , leaving the study of tissues to histology and cells to cytology and cell biology . Human anatomy is a special field within anatomy general (animal). We emphasize that the anatomy is a database according to the purpose in which you want to go.

Under a systematic view, the human body as the bodies of animals, 'is organized at different levels in a hierarchy. Thus is composed of apparatus. These systems comprise them, which in turn are composed of organs , which are composed of tissues which are formed by cells , which consist of molecules , etc.. Other views (functional, morphogenetic , clinic , etc.) under other criteria, understand the human body a little differently.5

Discussion

A human body is divided in two lines. First, is the middle line which is characterized by an imaginary line that divides the body into two halves in the center or right side and left side. There are also other center lines for example, separating the top and bottom of the body or the front and back surfaces of the body. The stability of the median line has a central axis to the body allowing the mobility. This stability allows the person in addition to postural adjustments. To movements in space and act, the person must be aware of the stability of its central body "midline stability" and how it should find its center when the body is in motion. For most tasks involving the use of hands, the left hand is running in the workspace left and right hand in space law. For example, for an object on the left the child will use his left hand and vice versa. In this context, the side of the workspace is determined in different ways either by midline sagittal (center of the body) or by the head (the center of the head) or gaze direction (the center head and / or eyes). In some tasks, it is necessary to cross the midline.

Second, is the intersection of the center line is defined by a movement vis-à-vis the center lines or around the body. For example, the act of using his hand on the opposite side of the body involves a crossing of the midline. Many recreational activities such as some tennis, piano, and activities of daily living such as dressing, the activities of motor as fine cutting, coloring and activities of global motor skills such as hitting a ball involve the action. Crossing the midline is a key step in children's motor development. The avoided crossing of the midline is a difficult for some children such as those with fragile X syndrome is a hereditary syndrome. Moreover, such avoidance reflects a problem of bilateral integration and sequencing. This term is relevant to occupational therapy as a child with a problem at the intersection ...
