A flexor muscle is any muscle that bends a body part at a joint. The contraction of a flexor muscle decreases the angle between two bones, when bending.
Flexor muscles is a skeletal muscle that moves bones and is controlled voluntarily.
Some examples of flexor muscles are
- the hip flexors, which flex the hip and move the thigh toward the body
- and the bicep, that flexes the elbow and move the forearm toward the shoulder
Skeletal muscles are three muscle types either smooth, cardiac, or skeletal.
There are four types of skeletal muscles categorized by specific movements. They include the flexors, extendors, abductors, and adductors.
Flexor muscles are located in many parts of the body like the
- elbow
- forearm
- fingers, toes
- vertebrae
- neck
- hips
- knees
- feet
- and hands
Muscles that flex the ankle or toes are plantar flexors and dorsiflexors, rather than flexors and extension muscles.
Frequently, many muscles consolidate to flex a joint. Flexing the knee, for example, involves the biceps femoris, semitendinosus, semimembranosus, and normally six additional muscles.
Most flexors are in the sagittal plane of the body, which is a postulated line bisecting the body into front and back portions.
Flexion and extension movements usually is front to back direction, while lateral mobility are performed by the abductors and adductors. Muscles only pull and not push, usually polarized into two antagonistic muscles. A flexor muscle works opposite an extension muscle, which increases and angle or straightens, a joint.
