Types of Movement
- Abduction is movement away from the center, as spreading the toes or fingers apart.
- Adduction is movement toward the midline of the body, as bringing the fingers and toes together.
- Angular motion is comprised of flexion, extension, adduction, and abduction.
In the world of mechanics, there are four basic types of motion. These four are rotary, oscillating, linear and reciprocating. Each one moves in a slightly different way and each type of achieved using different mechanical means that help us understand linear motion and motion control.
- Flexion and Extension. Flexion and extension are movements that take place within the sagittal plane and involve anterior or posterior movements of the body or limbs.
- Abduction and Adduction.
- Circumduction.
- Rotation.
- Supination and Pronation.
- Dorsiflexion and Plantar Flexion.
- Inversion and Eversion.
- Protraction and Retraction.
18-2). There is also a slight side-to-side movement. The basic movements involved in walking are (1) flexion and extension at the hip, knee, and ankle joints and at the front part of the foot; (2) abduction and adduction, chiefly at the hip joint (fig. 18-3); and (3) rotation, mainly at the hip and knee joints.
In the limbs, flexion decreases the angle between the bones (bending of the joint), while extension increases the angle and straightens the joint. For the upper limb, all anterior motions are flexion and all posterior motions are extension.
Anatomical Movements of the Human Body
- Planes.
- Axes.
- Flexion and extension.
- Abduction and adduction.
- Elevation and depression.
- Internal and external rotation (medial and lateral rotation)
- Circumduction.
- Pronation and supination.
The movement of synovial joints can be classified as one of four different types: gliding, angular, rotational, or special movement.
- Gliding Movement. Gliding movements occur as relatively flat bone surfaces move past each other.
- Angular Movement.
- Rotational Movement.
Locomotor skills - such as running, jumping, hopping, and galloping. Ball skills - such as catching, throwing, kicking, underarm roll and striking.
Abduction moves the limb laterally away from the midline of the body, while adduction is the opposing movement that brings the limb toward the body or across the midline. Spreading the fingers or toes apart is also abduction, while bringing the fingers or toes together is adduction.
Circumduction – this is where the limb moves in a circle. This occurs at the shoulder joint during an overarm tennis serve or cricket bowl. Rotation – this is where the limb turns round its long axis, like using a screw driver.
angular motion that is the medial movement of a body part toward the midline of the body. motion that occurs only at specific joints, some movements include depression and elevation, dorsiflexion and plantar flexion, inversion and eversion, etc. depression. inferior movement of a part of the body.
Rotation is the process or act of turning or circling around something. An example of rotation is the earth's orbit around the sun. An example of rotation is a group of people holding hands in a circle and walking in the same direction.
The joint with the greatest range of motion is the ball-and-socket joint. At these joints, the rounded head of one bone (the ball) fits into the concave articulation (the socket) of the adjacent bone (see Figure 3f). The hip joint and the glenohumeral (shoulder) joint are the only ball-and-socket joints of the body.
Internal and external rotation (medial and lateral rotation)
Rotation refers to movements made about the longitudinal axis and in the transverse plane. Internal rotation is rotating a joint towards the midline; external rotation is rotating a joint away from the midline.Twisting or rotational movements occur in the transverse plane, such as twisting your head from side to side. Front to back movements occur in the sagittal plane, such as walking, pushing, pulling and squatting.
Depression of the femur before and during a jump is accomplished by the proximal joint muscles that serve also to stabilize the proximal joints when the forces of the extending femur–tibia joint are transferred to the whole body.
These three axes, referred to as longitudinal, lateral and vertical, are each perpendicular to the others and intersect at the aircraft centre of gravity. Motion around the longitudinal axis, the lateral axis and the vertical axis are referred to as roll, pitch and yaw respectively.
A tendon is a fibrous connective tissue which attaches muscle to bone. Tendons may also attach muscles to structures such as the eyeball. A tendon serves to move the bone or structure.
Abduction and adduction motions occur within the coronal plane and involve medial-lateral motions of the limbs, fingers, toes, or thumb. Abduction moves the limb laterally away from the midline of the body, while adduction is the opposing movement that brings the limb toward the body or across the midline.
Inversion is the turning of the foot to angle the bottom of the foot toward the midline, while eversion turns the bottom of the foot away from the midline. The foot has a greater range of inversion than eversion motion.
Movement. Movements of the body are brought about by the harmonious contraction and relaxation of selected muscles. Contraction occurs when nerve impulses are transmitted across neuromuscular junctions to the membrane covering each muscle fibre. Skeletal muscles are attached to bones and produce movement at the joints.
When you do jumping jacks, which lower limb movements are necessary. You move your lower limbs away from the body's midline; this movement is called abduction. When you bring the lower limbs back together, the movement is adduction.
Depression and Elevation
Similarly, elevation of the mandible is the upward movement of the lower jaw used to close the mouth or bite on something, and depression is the downward movement that produces opening of the mouth (see Figure 6).Abduction moves the limb laterally away from the midline of the body, while adduction is the opposing movement that brings the limb toward the body or across the midline. Spreading the fingers or toes apart is also abduction, while bringing the fingers or toes together is adduction.
Synovial joints achieve movement at the point of contact of the articulating bones. Synovial joints allow bones to slide past each other or to rotate around each other. This produces movements called abduction (away), adduction (towards), extension (open), flexion (close), and rotation.
1.4. 5 ABDUCTION refers to movement of a part of the body away from the median plane. This usually takes place in the coronal plane e.g. moving an upper limb away from the side of the body. In abduction of the digits, the term refers to spreading them apart.
Standing on tiptoes is an example of plantar flexion. Many daily activities involve plantar flexion. One typical example is pressing the foot down on the gas pedal in a car. Standing on the tips of the toes to reach a high shelf is also plantar flexion.
To reinforce the 8 locomotor skills of walking, running, jumping, hopping, skipping, sliding, galloping, and leaping.

Abduction and adduction are two terms that are used to describe movements towards or away from the midline of the body. Abduction is a movement away from the midline – just as abducting someone is to take them away. For example, abduction of the shoulder raises the arms out to the sides of the body.
Abduction and adduction motions occur within the coronal plane and involve medial-lateral motions of the limbs, fingers, toes, or thumb. Abduction moves the limb laterally away from the midline of the body, while adduction is the opposing movement that brings the limb toward the body or across the midline.
Condyloid joint. A condyloid joint (also called condylar, ellipsoidal, or bicondylar) is an ovoid articular surface, or condyle that is received into an elliptical cavity. This permits movement in two planes, allowing flexion, extension, adduction, abduction, and circumduction.
A synovial joint, also known as a diarthrosis, is the most common and most movable type of joint in a mammal's body. Diarthroses are freely movable articulations. In these joints, the contiguous bony surfaces are covered with articular cartilage and connected by ligaments lined by synovial membrane.
Dorsiflexion is the action of raising the foot upwards towards the shin. It means the flexion of the foot in the dorsal, or upward, direction.
circumduction(Noun) The circular (or, more precisely, conical) movement of a body part, such as a ball-and-socket joint or the eye. It consists of a combination of flexion, extension, adduction, and abduction. "Windmilling" the arms or rotating the hand from the wrist are examples of circumductive movement.
