(e) Abduction and adduction are motions of the limbs, hand, fingers, or toes in the coronal (medial–lateral) plane of movement. (c)–(d) Anterior bending of the head or vertebral column is flexion, while any posterior-going movement is extension. These movements take place at the shoulder, hip, elbow, knee, wrist, metacarpophalangeal, metatarsophalangeal, and interphalangeal joints. (a)–(b) Flexion and extension motions are in the sagittal (anterior–posterior) plane of motion. What motions involve increasing or decreasing the angle of the foot at the ankle? Figure 9.5.1 – Movements of the Body, Part 1: Synovial joints give the body many ways in which to move. Watch this video to learn about anatomical motions. Refer to Figure 9.5.1 as you go through this section. Body movements are always described in relation to the anatomical position of the body: upright stance, with upper limbs to the side of body and palms facing forward. Movement types are generally paired, with one directly opposing the other. There are many types of movement that can occur at synovial joints ( Table 9.1). Overall, each type of synovial joint is necessary to provide the body with its great flexibility and mobility. While the ball-and-socket joint gives the greatest range of movement at an individual joint, in other regions of the body, several joints may work together to produce a particular movement. The degree and type of movement that can be produced at a synovial joint is determined by its structural type. Each movement at a synovial joint results from the contraction or relaxation of the muscles that are attached to the bones on either side of the articulation. Synovial joints allow the body a tremendous range of movements. Identify the joints that allow for these motions. ![]() Demonstrate the different types of body movements.By the end of this section, you will be able to:ĭefine and identify the different body movements
