What is flexion vs extension?

Flexion and extension are movements that occur in the sagittal plane. They refer to increasing and decreasing the angle between two body parts: Flexion refers to a movement that decreases the angle between two body parts. Extension refers to a movement that increases the angle between two body parts.

What is muscle flexion?

Flexor muscle, any of the muscles that decrease the angle between bones on two sides of a joint, as in bending the elbow or knee. Several of the muscles of the hands and feet are named for this function.

What does it mean for your muscles to go through extension?

An extension is a physical position that increases the angle between the bones of the limb at a joint. It occurs when muscles contract and bones move the joint from a bent position to a straight position. In other words, that joint can basically be opened until it is straight.

How does age affect strength?

Aging leads to a progressive decrease of muscle strength and flexibility. Strength peaks around 25 years of age, plateaus through 35 or 40 years of age, and then shows an accelerating decline, with 25% loss of peak force by the age of 65 years.

What happens during muscle flexion?

Flexion and extension are usually movements forward and backward from the body, such as nodding the head. 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.

Why do we need antagonist muscle?

Antagonist muscles are simply the muscles that produce an opposing joint torque to the agonist muscles. This torque can aid in controlling a motion. The opposing torque can slow movement down – especially in the case of a ballistic movement.

What’s the difference between a flexion and an extension?

In anatomy, flexion and extension are two opposing movements that muscles can perform about a joint. Flexion is a motion in which the angle of the joint involved decreases, as in bending the elbow so that the forearm is brought toward the upper arm. Extension is a movement that increases the angle of the joint, as in straightening the elbow.

What’s the difference between stretching and flexing a muscle?

Difference Between Stretching & Flexing a Muscle. The human body contains three main types of muscles: cardiac, smooth and skeletal. The first two types of muscles are involuntary, meaning that you cannot control their contractions. You control the skeletal muscles, the muscles responsible for moving your body …

Which is an example of a flexion movement?

Flexion refers to a movement that decreases the angle between two body parts. The opposite movement of flexion is the extension. Flexion of the elbow, which decreases the angle between ulnar and the humerus, is a general example of flexion. Dorsiflexion, plantar flexion, and lateral flexion are special movements in flexion.

Which is the opposite muscle of the flexor muscle?

In the illustration below, the image on the right shows the biceps flexing. The opposing muscle of a flexor is called the “extensor” muscle. Your triceps is an extensor. When you contract your triceps your arm straightens and the angle between the forearm and the upper arm increases.

Which is an example of a flexor muscle?

Flexion is a bending movement where the angle between two body parts decreases. Contracting the biceps exhibits flexion as it brings the forearm closer to the upper arm, decreasing the angle between the two. Therefore, biceps are described as a flexor muscle (biceps flexing).

What does it mean when you flex your biceps?

“Flexion” is a bending movement where the angle between two parts decreases. Contracting your biceps exhibits flexion, i.e. it brings your forearm closer to your upper arm and decreasing the angle between the two. So, your biceps is described as a “flexor” muscle. In the illustration below, the image on the right shows the biceps flexing.
