The flexor muscles are found in the quadriceps as well as the sartorius, iliopsoas, psoas minor, and the pectineus muscles. The rectus femoris is the primary flexor muscle of the quadriceps.
The extensor muscles are found in the hamstrings and the gluteus maximus.
The Flexor and Extensor muscles
The flexor muscle contracts and shortens to bend the joint, moving the lower wing up towards the upper wing. The extensor muscle then relaxes to allow this movement. The coordinated action of the flexor and extensor muscles allows for controlled movement of the wings.
The Flexor and Extensor muscles controls this movements. In particular, a chicken or a fowl's Flexor and Extensor muscles are called Pectoralis major and Pectoralis minor, respectively.Hope that helped! :))
The hip flexor muscle is located in the front of the hip and upper thigh area in the human body.
The posterior deltoid is one extensor of the upper arm.
the hind legs are folded in the shape of a Z in the position poised for a jump. the legs of grasshopper jerks backwards when the extensor muscle contracts. when the flexor muscle in the upper part of the grasshopper's legs contract, the lower parts of the legs are pulled towards the body. the grasshopper propels forward and upward into the air. if the hind leg muscle injured, the grasshopper cannot jump but it can walk.
The muscle/muscles that bend your arms are called Flexor and Extensor.
The flexor carpi ulnaris muscle is an upper limb muscle that has double innervation from both the ulnar and medial nerves.
Well there are two muscles which bend the arm: bending your arm from a straight position to a bent position uses the bicep (Latin name - Bicep Brachii) which is on the topside of your upper arm. Bending your arm from a bent position to a straight position uses the tricep (Latin name - Tricep Brachii) which is on the underside of your upper arm. Both muscles work in sinc with each other, so as one muscle tenses and contracts (causing the arm to bend one way or the other), the other losens.
An example of a flexor muscle is the biceps brachii in the upper arm. Its function is to bend the arm at the elbow joint, allowing for movements like lifting and curling.
The main extensor of the arm is the triceps brachii muscle. It is located on the back of the upper arm and is responsible for extending the elbow joint, which straightens the arm.
