Is Extension The Opposite Of Flexion?
Is extension the opposite of flexion? In the limbs, flexion decreases the angle between the bones (bending of the joint), while extension increases the angle and straightens the joint.
What does flexion and extension mean?
Flexion – bending a joint. This occurs when the angle of a joint decreases. For example, the elbow flexes when performing a biceps curl. The knee flexes in preparation for kicking a ball. Extension – straightening a joint.
What is difference between flexion and extension?
Flexion and extension are two anatomical terms used to describe angular motion. The main difference between flexion and extension is that flexion is the action that brings the two bones together, decreasing the angle between the bones whereas extension is the action that increases the angle between the two bones.
What does extension mean in anatomy?
Extension: The process of straitening or the state of being strait. Extension of the hip and knee joints is necessary to stand up from the sitting position.
What is dorsiflexion and plantar flexion?
The term plantar flexion refers to the movement of the foot in a downward motion away from the body. It also enables the opposite movement, dorsiflexion, which is the movement of the foot toward the leg. Your ankle joint supplies the power for 40% to 70% of your forward movement during walking.

What is hip extension vs flexion?
The structure of the hip allows a wide range of motion to (and between) the extreme ranges of anterior, posterior, medial, and lateral movement. Raising the leg toward the front is termed flexion; pushing the leg toward the back is termed extension (Figure 2).
What is the opposite of flexion?
The movement at a joint which decreases the angle between two adjacent body segments is know as flexion. The opposite action is extension, where the angle between body segments is increased.
What is muscle flexion?
Flexion: decreasing the angle between two bones (bending). Extension: increasing the angle between two bones (straightening a bend). The triceps brachii and anconeus are muscles that extend the elbow. The biceps brachii, brachialis, and brachioradialis flex the elbow.
What is adduction and abduction?
“Abduction refers to your body part moving away from the midline of your body, adduction is coming towards the midline of your body,” explains Kewley. He points out that “if you think about it, if you're always working abduction and not working adduction you're not actually working any of your adductors in your body.”
What is the difference between flexor and extensor muscles?
The key difference between flexor and extensor muscles is that flexor muscles facilitate the process of flexion in the body, while extensor muscles facilitate the process of extension in the body. Flexion is a bending movement where the angle between two body parts decreases.
What is elevation and depression in anatomy?
Depression and elevation are downward and upward movements of the scapula or mandible. The upward movement of the scapula and shoulder is elevation, while a downward movement is depression.
Why is dorsiflexion called?
Dorsiflexion and plantar flexion refer to extension or flexion of the foot at the ankle. These terms refer to flexion in direction of the "back" of the foot, which is the upper surface of the foot when standing, and flexion in direction of the sole of the foot.
What is the opposite of dorsiflexion?
Plantar flexion is the opposite of dorsiflexion and involves moving the foot in a downward direction, toward the ground. The muscles whose tendons cause plantar flexion are located on the back (posterior) and inside of the leg, and pass into the back of the foot via the ankle joint. These include: tibialis posterior.
What is Extension in non locomotor?
you are extending if you are increasing the angle of a joint. stretching is the other word for extension.
What is health extension?
Medical Definition of extension

What is the dorsum of the foot?
The dorsum of foot is the area facing upwards while standing. This definition incorporates text from the wikipedia website - Wikipedia: The free encyclopedia. ( 2004, July 22).
Is dorsiflexion concentric or eccentric?
In order to accomplish this, eccentric muscle contraction occurred during passive ankle dorsiflexion mode, and the concentric phase occurred during the ankle plantarflexion mode.
What is footballer's ankle?
Footballer's ankle occurs when the soft tissue (tendons and ligaments) in the ankle get pinched between the bones. Due to excessive kicking and bending and stretching of the foot, the ligaments can also thicken and cause bone growth at the front of the ankle causing pain.
Is squatting hip flexion or extension?
Considering that the squat exercise requires flexion and extension of the knee and hip joints, respectively, a resistance training program based on squat exercises may efficiently increase the flexion and extension strength of both the knee and hip.
What is trunk flexion?
Trunk flexion was the result of a simultaneous forward pelvic tilt and flexion of the spine. For trunk movements up to 550, spine flexion dominated the movement, whereas for larger movements a major part of the amplitude was caused by pelvic tilt.
What is hip abduction?
Hip abduction is the movement of the leg away from the midline of the body. We use this action every day when we step to the side, get out of bed, and get out of the car. The hip abductors are important and often forgotten muscles that contribute to our ability to stand, walk, and rotate our legs with ease.
What is the opposite of flexing a muscle?
Opposite of to bend or become bent. unbend. straighten. extend. flatten.
What does inversion mean in anatomy?
Invert: 1) To turn inward. To invert the foot is to move its forepart toward the midline of the body. 2) To turn upside down or inside out.
What is shoulder flexion and extension?
The words flexion and extension refer to how the shoulder muscles are moving in relation to how you move your arms. A shoulder flexion is when you move your arms anywhere from a resting position by your sides to straight above your head. An extension is when you move your arms and stick them out behind you.
What is your psoas?
The psoas muscle is located in the lower lumbar region of the spine and extends through the pelvis to the femur. This muscle works by flexing the hip joint and lifting the upper leg towards the body. A common example of the movement created from this muscle is walking.
What is an antagonist muscle?
In an antagonistic muscle pair as one muscle contracts the other muscle relaxes or lengthens. The muscle that is contracting is called the agonist and the muscle that is relaxing or lengthening is called the antagonist.
What is fixator muscle?
Medical Definition of fixator
: a muscle that stabilizes or fixes a part of the body to which a muscle in the process of moving another part is attached.
What is abduction anatomy?
In general terms, abduction in the anatomical sense is classified as the motion of a limb or appendage away from the midline of the body. In the case of arm abduction, it is the movement of the arms away from the body within the plane of the torso (sagittal plane).
What is a joint?
A joint is the part of the body where two or more bones meet to allow movement. Generally speaking, the greater the range of movement, the higher the risk of injury because the strength of the joint is reduced. The six types of freely movable joint include ball and socket, saddle, hinge, condyloid, pivot and gliding.
What is abductor and adductor?
The key difference between abductor and adductor muscles is that the abductor muscles are the muscles that pull body parts outwards from the midline while the adductor muscles are the muscles that pull body parts towards the midline of the body.
Is a bicep curl flexion or extension?
Flexion – bending a joint. This occurs when the angle of a joint decreases. For example, the elbow flexes when performing a biceps curl. Extension – straightening a joint.
What is the difference between flexors and extensors give an example?
Flexors are muscles involved in flexing a muscle, like the biceps. These muscles extend two muscles further, e.g. Triceps. 3 Extensors are muscles involved in extending a muscle, like thetriceps. 4opens a joint and are the opposite to flexor muscles, which closes it.
