A physical posture that increases the angle between the bones of the limb at a joint is called an extension. When muscles contract and bones move the joint from a bent to a straight posture, this happens. It is a backward or forward movement for backward or forward-moving joints, such as the neck.
Similarly, What is spinal extension?
Spinal extension is the inverse of flexion; you could think of it as back-arching, but there’s a little more skill involved in this exercise. You’ll start the action with your inhalation. When you inhale, your spine automatically extends.

Secondly, What’s an example of extension?
An extension is defined as an expansion to a building, an additional phone line linked to the original line, or an additional period of time provided to someone to settle a debt.

Also, What is extension of the arm?
When you extend your arms behind you, it’s called an extension. The anterior deltoid, pectoralis major, and coracobrachialis are the muscles involved in the flexion action. The latissimus dorsi, teres major and minor, and posterior deltoid muscles are used in shoulder extension.
People also ask, How do I remember my flexion and extension?
Just keep in mind that flexion means forward. This process happens at several joints and always closes the joint by bringing the bones that make up the joint closer together. The opposite of flexion is extension, which reduces the angle between the two bones or opens the joint.

What is a shoulder extension?
The unrestricted movement of the upper arm falling from an elevated position in front of the body, enabling the whole extremity to return to a normal resting posture at the waist, and continuing behind the body, allowing limited mobility of the arm behind the back is referred to as shoulder extension.
Which joints are extended?
Knee flexion is when the knee bends to move the foot closer to the back of the thigh, and knee extension occurs when the knee straightens. The limbs’ hinge, condyloid, saddle, and ball-and-socket joints all show flexion and extension motions (see Figure 1). Flexion and extension are seen in Figure 1.
What is abduction adduction flexion and extension?
Abduction is a movement away from the body’s midline. Adduction is the movement of the body toward its midline. The straightening of limbs (increase in angle) at a joint is called extension. Flexion is the bending of the limbs at a joint (decrease of angle). A circular movement around a fixed point is known as rotation.
What is extension of the foot?
The backward bending and contracting of your hand or foot is known as dorsiflexion. This is the joint that connects your foot to your ankle and your hand to your wrist. You may dorsiflex your fingers and toes as well, however the phrase is commonly used to apply to your wrist or ankle.
What is the difference between extension and flexion of the wrist?
When your wrist flexion is normal, the muscles, bones, and tendons that make up your wrist are functioning normally. Flexion is the inverse of extension, which is when you move your hand backwards so that your palm faces up. Wrist extension is also a component of the typical range of motion.
What is abduction and adduction?
Abduction and adduction are two terminologies that relate to different types of bodily motions. The reverse of adduction is abduction. Abduction is the movement of limbs (arms, legs, or fingers) away from the body’s midline. Adduction, on the other hand, is when you move your limbs closer to the midline.
What is an extension in medical terms?
Extension is defined in medical terms. 1: restoring a shattered or dislocated limb to its normal place by stretching it. 2: an unbending movement around a limb’s joint (such as the knee or elbow) that increases the angle between the limb’s bones at the joint — compare flexion sensation. 1. enlargement.
What does extension mean in dance?
The capacity of a dancer to lift and maintain a leg extended in the air is referred to as extension in English classical ballet. In classical ballet, proper extension is especially vital for ladies, but it is also becoming more necessary for males.
What does extension mean in science?
Extension. 1. (Orthopaedics) The movement of two components of a jointed part being moved apart from one another. 2. (Anatomy) a movement in which the members of a limb are brought into or toward a straight relationship.
What is wrist extension?
Wrist extension is the rearward movement of the hand towards the forearm’s posterior side. Working in a position where your wrist is extended for an extended period of time may lead to repetitive strain injuries like carpal tunnel syndrome.
What is elbow extension and flexion?
Elbow flexion is when your forearm moves toward your body by bending at the elbow. Elbow extension is the polar opposite of flexion. The humerus, which is located in your upper arm, is one of the three bones involved in elbow flexion. The ulna is located on the forearm’s little finger side.
What is knee extension?
A knee extension is a resistance training exercise in which you put a weight on your shin and flex your quadriceps muscles to extend your lower leg until the whole leg is pointing straight out from a sitting posture.
What is hip extensor?
The gluteus maximus and hamstrings are the major hip extensors (i.e., the long head of the biceps femoris, the semitendinosus, and the semimembranosus). The adductor magnus’ extensor head (explained later in this chapter) is also a main hip extensor.
What is flexion of knee?
Flexion is the action of bending the knee. Extinction is the polar opposite of compression. The opposing muscle groups govern flexion and extension.
What is flexion of the arm?
Arm flexion refers to the movement of the distal humerus ventrally in the anatomic plane. It entails lifting the arm and isolated flexion, which may range from 150 to 170 degrees. Arm extension, on the other hand, contributes to the combined action of shoulder circumduction.
What is adduction of arm?
In the coronal plane, arm adduction refers to the movement of the arm towards the midline of the body. Most people can handle 40 degrees of solitary adduction. It is the inverse of arm abduction and helps to shoulder circumduction as a whole. It’s made by the pectoralis major muscle (sternal part).
What is leg flexion?
The medical word for bending an arm or leg is flexion. In technical terms, it’s a physical posture that reduces the angle between the limb’s bones at a joint. When your muscles tighten, your bones and joints bend into a bowed posture. 1
How do you do a knee extension?
Make sure the angle between your thighs and your lower legs is roughly 90 degrees. Slowly raise your lower legs until your knees are almost completely straight. Return to the starting position carefully. The muscles in the front of your thighs will feel tense.
What’s the difference between extension and hyperextension?
is that hyperextension is the act of extending or the state of being stretched; a stretching out; enlargement in width or continuation in length; increase; augmentation; expansion, while extension is the act of extending or the state of being extended.
What is a adduction movement?
Adduction is when a limb or hand is brought toward or across the body’s midline, or when the fingers or toes are brought together. Circumduction is the circular movement of a limb, hand, or fingers employing a combination of flexion, adduction, extension, and abduction actions in a circular pattern.
