Anatomical terms of motion When a joint can move forward and backward, such as the neck and trunk, flexion refers to movement in the anterior direction. Flexion of the shoulder or hip refers to movement of the arm or leg forward. Extension is the opposite of flexion, describing a straightening movement that increases the angle between body parts.When a joint can move forward and backward, such as the neck and trunk, extension refers to movement in the posterior direction.For example, when standing up, the knees are extended.ee also: List of flexors of the human body and List of extensors of the human body. Flexion and extension describe movements that affect the angle between two parts of the body. These terms come from the Latin words with the same meaning.

Anatomical terms of motion In general, motion is classified according to the anatomical plane it occurs in. Flexion and extension are examples of angular motions, in which two axes of a joint are brought closer together or moved further apart.

Movement and Muscles at the Shoulder flexion and extension Movement and Muscles at the Shoulder flexion and extension It's another good thing that I got Biggie for these pictures, because flexion and extension are movements in the sagittal plane—i.e., from front to back.

- Lateral Flexion. Lateral flexion is the motion of bending your torso side to side. From a standing position, challenge your core muscles in the frontal plane. Hold a dumbbell in your right hand. Place your left hand behind your head and stand with your feet hip-width apart.

What Does Lateral Flexion of the Torso Involve? Muscles. Lateral flexion involves side bending away from the midline of the body, called abduction, and then straightening back to the center, called adduction. Along with rotation, forward flexion and extension, it is one of the four movements possible by the spine.hoto Credit Robert Daly/OJO Images/Getty Images. When you talk about core training, the phrase lateral flexion doesn't roll off your tongue; however, it is an essential component of building a strong trunk that can help you execute athletic and daily activities with ease, finesse and less risk of injury.

Anatomical Terms of Movement Flexion at the elbow is decreasing the angle between the ulna and the humerus. When the knee flexes, the ankle moves closer to the buttock, and the angle between the femur and tibia gets smaller. Extension refers to a movement that increases the angle between two body parts.

Summary Extension occurs when the angle between two adjacent segments in the body increases as the ventral surfaces of the segments move away from each other and occurs in a sagittal plan about a frontal axis. An exception is extension of the thumb, which takes place in a frontal plane about a sagittal axis. Flexion occurs when the angle between two adjacent segments in the body decreases as the ventral surfaces of the segments approximate each other and occurs in a sagittal plane about a frontal axis. An exception is flexion of the thumb, which takes place in a frontal plane about a sagittal axis.

- Flexion contracture. A flexion contracture or flexion deformity is when someone is not able to fully straighten their leg either actively or passively. -. ‘Gon’ is a Greek prefix implying ‘knee’ so a ‘goniometer’ means an instrument for measuring the knee, although in practice it can be used for measuring the range-of-motion - or ...

Anatomy and Physiology- muscle movements Abduction- Is any movement that takes a body part away from the midline of the body. Adduction- involves the movement of a body part towards the midline of the body. Dorsiflexion and Plantar flexion Dorsiflexion-characterised by the pointing of the toes up. Plantar flexion- is unique to the ankle joint and is characterised by the pointing of the toes.

Structural Biochemistry/Cell Signaling Pathways/Muscular System The muscle is called a flexor if the centers of the connected …bones are brought closer together when the muscle contracts, and the movement is called flexion. (Biceps)    The muscle is called an extensor if the bones move away from each other when the muscle contracts, and the movement is called extension.

Anatomical terms of motion Adduction refers to a motion that pulls a structure or part toward the midline of the body, or towards the midline of a limb. In the case of fingers and toes, it refers to bringing the digits together, towards the centerline of the hand or foot. Adduction of the wrist is also called ulnar deviation.he centre of the body is defined as the mid sagittal plane. These terms come from the Latin words with the same meaning. Abduction refers to a motion that pulls a structure or part away from the midline of the body.

Types of Body Movements 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-going motions are flexion and all posterior-going motions are extension.

Flexion Definition Flexion Definition. Flexion is the anatomical name for forward bending. When treating back pain, many spine specialists encourage exercises to strengthen the muscles that act to bring the spine into flexion.In the lower back, approximately 50% of flexion occurs at the hips, and 50% occurs at the lower spine.lexion Definition. Flexion is the anatomical name for forward bending. When treating back pain, many spine specialists encourage exercises to strengthen the muscles that act to bring the spine into flexion.

Normal Range of Motion in Back Extension and Flexion Your cervical spine supports the weight of your head. A person with normal range of motion for the cervical spine nods his head by flexing and extending the muscles that control his cervical spine. Normal range of cervical motion is 60 degree cervical flexion and 75 degree cervical extension. Your thoracic area has limited range of motion.

Arm Flexion and Extension It is typically thought of as movement of the arm posteriorly, but remember that any motion away from full flexion is extension. Muscles: latissimus dorsi and teres major, long head of triceps, posterior fibers of the deltoid.t is typically thought of as an anterior excursion of the arm, but remember that any motion away from full extension is flexion. Muscles: pectoralis major, coracobrachialis, biceps brachii, anterior fibers of deltoid.

- PROBLEM. Knee flexion and extension range of motion (ROM) is necessary for functional and sport specific activities. Loss of full ROM at the knee joint can have detrimental effects on the function of the entire lower extremity.ue to these complications that can occur following the loss of knee flexion or extension, regaining full functional ROM through treatment is crucial. Research supports the use of sustained force for 10 to 45 minutes at a time to increase knee ROM.

Anatomical Terms of Movement The dorsum of the hand is the posterior surface, and so movement in that direction is extension. Therefore we can say that dorsiflexion of the wrist is the same as extension. Plantarflexion refers extension at the ankle, so that the foot points inferiorly.

Group 2 Student Page Flexion: Bending movement and decreases the angle between articulating bones. Extension: Straightening movement and increases the angle between Articulating bones. Both Flexion and Extension are found in nearly all synovial joints (freely moving) like toes, hands, knee and elbows, and usually occurs on the sagital plane.

- Lateral flexion usually refers to the spine, or vertebral column. You can laterally flex your head, neck, or your torso (back). answer Lateral direction is away from the midline of the body (an imaginary line from the middle of your node to your belly button).imply stated, flexion is when the angle around a joint is decreased from it's normal position (from the anatomical position) in the SAGITTAL plane. The sagittal plane is an i … maginary line that splits your body into left and right pieces. All flexion moves in this plane.
