The flexor muscles of the leg include the hamstrings and the iliopsoas, which help to bend the knee and bring the thigh towards the abdomen. The extensor muscles of the leg are primarily the quadriceps, which straighten the knee and help to lift the leg.

What forearm muscles are used to turn a can opener handle?
The flexor digitorum profundus is a muscle in the forearm that flexes the fingers and holds the handle.The flexor carpi radialis and extensor carpi radialis longus allow you 'bend' the wrist as you turn the handle.
How do the flexor and extensor muscles work together in the body?
When bones attached to a muscle are connected by a flexible joint, contraction of the muscle moves the skeleton. The muscle is called a flexor if the centers of the connected bones are brought closer together when the muscle contracts, and the movement is called flexion. (Biceps)The muscle is called an extensor if the bones move away from each other when the muscle contracts, and the movement is called extension. (Triceps)
What muscle produces extension of the fingers joints and wrist?
The muscles that produce extension of the finger joints and wrist are the extensor muscles. In the forearm, the specific extensor muscles responsible for extension of the fingers and wrist include the extensor digitorum and extensor carpi radialis muscles.
Which pair of the opposing muscle controls the movements in the upper and lower ends of the chicken's wing?
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! :))
Is the trapezius a flexor or an extensor?
The trapezius muscle is an extensor muscle. It is responsible for extending and laterally flexing the neck, as well as retracting and elevating the scapula.
An extensor-flexor muscle not located in the anterior or posterior?
The muscles of the legs do not follow the generalization that extensor muscles are on the posterior and flexor muscles are on the anterior.
What does the 'extensor muscle' do?
Extensor muscles open a joint and are the opposite to flexor muscles, which close it. I imagine triceps are extensor, while biceps are flexor.
What is an example of a flexor muscle?
The triceps are extensor muscles.
Do skeletal muscles work in paires?
All skeletal muscles will have a flexor and an extensor. The flexor bends the joint. The extensor straightens it out again.
Do most skeletal muscles work in antagonistic pairs?
Yes. Skeletal muscles will have a flexor and an extensor. The flexor bends the joint. The extensor straightens it out again.
What are extensors?
Extensor muscles open a joint and are the opposite to flexor muscles, which close it. I imagine triceps are extensor, while biceps are flexor.
Where is the Flexor and extensor muscle found in the upper leg?
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.
An exception to this generalization is the extensor flexor musculature of where?
An exception to this generalization is the extensor-flexor musculature of the forearm. In this region, the extensor muscles primarily control extension of the wrist and fingers, while the flexor muscles primarily control flexion. This muscle group plays a crucial role in intricate hand movements and grip strength.
What muscles are involved in radial and ulnar deviation?
flexor carpi radialis, flexor carpi ulnaris, extensor carpi radialis longus, extensor carpi ulnaris
What muscle is associated with the hand?
There are many muscles in the hand. Here are a few: extensor carpi radialis brevis extensor carpi radialis longus extensor carpi ulnaris extensor digitorum communis extensor indicis proprius extensor digiti minimi abductor pollicis longus extensor pollicis brevis extensor pollicis longus flexor carpi ulnaris flexor digitorum profundus flexor digitorum superficialis flexor carpi radialis flexor carpi ulnaris palmaris longus flexor pollicis longus abductor pollicis brevis flexor pollicis brevis opponens pollicis adductor pollicis palmaris brevis abductor digiti minimi flexor digiti minimi opponens digiti minimi Then each finger has a set of lumbrical muscles and 3 volar and 4 dorsal muscles
What do the front legs a grasshopper do?
Grasshoppers have three pairs of jointed legs. The first two pairs of smaller legs are used for walking and climbing while the third pair of hind legs are adapted for jumping.The movement at the joints are produced by the contraction of the antagonistic muscles which are the flexor and the extensor muscles. Grasshoppers have both extensor muscles and flexor muscles inside their femur to extend and flex their tibia.So when the grasshopper jumps, the flexor muscles contracts, bringing the hind legs to the 'Z' position (in which the hind legs are folded and appeared like the letter 'Z'). The extensor muscles will then contract while the flexor muscles relax (producing a powerful force to push against the ground) and thus, propels the grasshopper into the air. This mechanism is called jumping.Adapted from my Bio reference book;Nexus Vista SPM Biology :)
How many muscles to write?
There are around 25 muscles that are used in writing. Intrinsic hand muscles act only the digits: THENAR MUSCLES and ADDUCTOR POLLICIS HYPOTHENAR MUSCLES LUMBRICALES DORSAL INTEROSSEI PALMAR INTEROSSEI Extrinsic thumb muscles that act on the thumb: FLEXOR POLLICIS LONGUS EXTENSOR POLLICIS LONGUS EXTENSOR POLLICIS BREVIS ABDUCTOR POLLICIS LONGUS Extrinsic hand muscles act on the wrist and the digits: EXTENSOR DIGITORUM EXTENSOR INDICIS (PROPRIUS) EXTENSOR DIGITI MINIMI (PROPRIUS) FLEXOR DIGITORUM SUPERFICIALIS FLEXOR DIGITORUM PROFUNDUS Carpal muscles act at the wrist and, in some cases, the elbow: EXTENSOR CARPI RADIALIS LONGUS EXTENSOR CARPI RADIALIS BREVIS EXTENSOR CARPI ULNARIS FLEXOR CARPI RADIALIS FLEXOR CARPI ULNARIS PALMARIS LONGUS
