How do the flexor and extensor muscles work together in the body?
Wiki User
∙ 11y ago
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)

∙ 14y agoThere are flexors and extensors in the forearm and they control the movements of the hand and wrist.
If you hold your hand out (with the palm down), the flexors allow your hand to bend downward. The extensors allow your hand to bend upward.

∙ 13y agoFlexors and extensors are two types of muscles necessary for movement that can be found many places throughout the body.
Flexors are the muscles involved in flexion. The most common example is when you flex your arm to show how big your biceps are. You are contracting your biceps when you flex.
Extensors are involved in the extension of muscles. Extending would be when you straighten out your arm after flexing. Your triceps are the ones extending your arm back to the original position.

When explaining lateral and medial position what direction must the body be in?
Any explanation always starts with the body in anatomical position. The hands/forearms are supine (palm facing up like you're holding a cup of soup). This would make the pinky (and ulnar bone) medial with the thumb (and radius bone) lateral. At the elbow joint there is a lateral and medial epicondyle (a projection of the humerus where the forearm extensor and flexor muscles attach respectively). For lateral and medial positions this only really affects the forearm/hand since everything else is straightforward.
What is made up of the muscles that let you move?
The muscular system is made up of the muscles that enable movement. It consists of more than 600 muscles, including skeletal muscles, smooth muscles, and cardiac muscles. These muscles work together to allow voluntary and involuntary movements in the body.
What is the main action of the medial thigh muscles?
The main action of the medial thigh muscles is adduction, which means bringing the leg towards the midline of the body. These muscles work together to bring the legs closer together during movements like walking or crossing the legs.
What body system allows your body's movement?
Muscles.
How do muscles vary throughout the body?
Muscles vary throughout the body by voluntary and involuntary, voluntary is the muscles you can move and involuntary is the muscles you can't move.
Most flexor muscles are located on the aspect of the body most extensors are located An exception to this generalization is the extensor-flexor musculature of the?
anterior, posterior and knee
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.
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
When muscles contract they cause oarts of the body to bend. IS it extensor or flexor for the blank?
I meant parts not oarts. please help?!?!
List of synergist and antagonist muscles?
Some of the synergist muscles in the human body are the masseter, temporalis, supraspinatus, and the extensor digitorum. Examples if the antagonist muscles are the flexor digitorum superficial is, triceps brachii, extensor carpi radials longus, and the internal intercostals.
Which muscles extend or straighten a body part?
Extensor muscles extend or straighten a body part.
What muscle extends and adducts the wrist?
If you are studying A&P using the Marieb & Mitchell 10th Ed the answer you are looking for is: Extensor carpi radialis longus (d) (found on page 216 in the Lab Manual)Extensor Carpi Ulnaris
How many muscles do you use to click a mouse?
Clicking a mouse uses some of the smallest muscles in your body, the extensor muscles in the fingers. Many of them work together to achieve a click.
Where are most flexor muscles located?
A flexor muscle is a muscle which bends or flexes a limb. Most flexor muscles are located on the anterior aspect of the body.
How do muscles move?
Muscles move by contraction. When the cells shorten, the muscle pulls on the ligaments that connect the bones and the movable body parts. Depending on how a skeletal muscle acts, it may be classified as a flexor (decreases angle to joint) or an extensor (increases angle, straightening the joint).
what muscles are using in writing?
Well, assuming you are writing in shorthand or longhand with hands and fingers, there are multiple muscles required in the adept manipulation of those carpal bones.Most notable of these are the digitalis muscles. Extensor digitalis longus and extensor digitalis lateralis and a couple othersWell, assuming you are writing in shorthand or longhand with hands and fingers, there are multiple muscles required in the adept manipulation of those carpal bones.Most notable of these are the digitalis muscles. Extensor digitalis longus and extensor digitalis lateralis and a couple othersEdit: The answer above is incorrect. Extensor Digitalis Longus doesn't exist, they may have been thinking about the digitorum which, even so, is in the lower part of the body.-When flexing the fingers (moving the fingers toward the palm) a number of different muscles are being used for each finger.-Regarding the Thumb: Flexor pollicis brevis, Abductor pollicis brevis, Adductor pollicis brevis, extensor pollicus longus and Opponens pollicis are being used.-Regarding the first finger: 1st dorsal interosseous, 1st palmar interosseous and Flexor digitorum profundis/superficialis. --Regarding the second finger: 2nd dorsal interosseous, 2nd palmar interosseous and Flexor digitorum profundis/superficialis.And if you are taking into consideration the flexion of the wrist when writing you may want to include: flexor carpus radialis, flexor carpus ulnaris, and palmaris longus.These muscles should account for all movement, but if you find any extras feel free to edit this post further.-Anticipated Degree B.S. in Athletic Training, May 2017
What is meant by the term antagonistic muscle pairs?
Most muscles are arranged by opposing pairs at the joint area. Examples are adductors vs abductors, or flexors vs extensors, supinators vs pronators, Depressors vs levators Examples of the opposing pair muscles are Adductor - Adductor longus/brevis Abductor - Abductor pollicis longus/brevis Flexor - Flexor carpi radiais or Flexor carpi ulnaris Extensor - Extensor carpi radialis muscles or Extensor carpi ulnaris Supinator vs Pronator of forearm muscles Depressor - Depressor labii inferioris Levator - Levator scapulae Hope this was helpful.
