The major flexors of the knee are the hamstrings, which include: biceps femoris, semitendinosus, and semimembranosus.
The major extensors of the knee are the quadriceps, which include: rectus femoris, vastus medialis, and vastus lateralis.
Gastrocnemius and soleus muscles are very strong flexors of the ankle joint. The tibialis anterior and peroneus longus, together, are extensors of the ankle joint.
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! :))
Extensor. It will extend the neck and adduct the scapula.
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.
Flexor and extensor tendons connected to skeletal muscle
The contraction of a flexor allows the arm or leg to bend
The muscles of the legs do not follow the generalization that extensor muscles are on the posterior and flexor muscles are on the anterior.
Extensor muscles open a joint and are the opposite to flexor muscles, which close it. I imagine triceps are extensor, while biceps are flexor.
The triceps are extensor muscles.
All skeletal muscles will have a flexor and an extensor. The flexor bends the joint. The extensor straightens it out again.
Yes. Skeletal muscles will have a flexor and an extensor. The flexor bends the joint. The extensor straightens it out again.
Extensor muscles open a joint and are the opposite to flexor muscles, which close it. I imagine triceps are extensor, while biceps are flexor.
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.
flexor carpi radialis, flexor carpi ulnaris, extensor carpi radialis longus, extensor carpi ulnaris
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
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 :)
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
extensor digitorum, extensor indicis, extensor digiti minimi, flexor digitorum superficialis, and the flexor digitorum profundus. There are also extrinsic muscles that work only in the thumb; these include the flexor pollicis longus, extensor pollicis longus, extensor pollicis brevis, and adbuctor pollicis longus
