- Deltoid.
- Triceps.
- Flexor-carpi-ulnaris.
- Extensor-carpi-radialis longus.
- Extensor digitorum.
What muscles do in order for movement to occur?
- Agonist muscles shorten with contraction to produce a movement.
- Following contraction, the antagonist muscle paired to the agonist muscle returns the limb to the previous position.
What is the major muscle performing a movement?
Prime movers and antagonist
The prime mover, sometimes called the agonist , is the muscle that provides the primary force driving the action. An antagonist muscle is in opposition to a prime mover in that it provides some resistance and/or reverses a given movement.
What are the 5 types of muscle movements?
- Abduction.
- Adduction.
- Flexion.
- Hyperflexion.
- Extension.
- Hyperextension.
- Rotation.
- Internal rotation.
What are the 4 types of muscles?
- Skeletal muscle – the specialised tissue that is attached to bones and allows movement. ...
- Smooth muscle – located in various internal structures including the digestive tract, uterus and blood vessels such as arteries. ...
- Cardiac muscle – the muscle specific to the heart.
What muscle attachment is the most moveable?
The more stationary site of muscle attachment is called the origin and the more moveable site of muscle attachment is called the insertion .
Are biceps and triceps antagonistic pairs?
| Biceps Triceps | Pectoralis major Latissimus dorsi |
|---|
Why do muscles work in pairs?
Skeletal muscles only pull in one direction . ... For this reason they always come in pairs. When one muscle in a pair contracts, to bend a joint for example, its counterpart then contracts and pulls in the opposite direction to straighten the joint out again.
What are the 2 types of muscle movements?
There are two main types of muscle contraction: Isotonic contractions – these occur when a muscle contracts and changes length and there are two types: Isotonic eccentric contraction – this involves the muscle lengthening whilst it is under tension.
What are the two types of body movements?
The main types of body movements include flexion and extension, abduction and adduction, and rotation .
What is the longest muscle of the body?
The longest muscle in your body is the sartorius , a long thin muscle that runs down the length of the upper thigh, crossing the leg down to the inside of the knee. The primary functions of the sartorious are knee flexion and hip flexion and adduction.
What are 6 major types of muscles?

- Skeletal muscle.
- Smooth muscle.
- Cardiac muscle.
- Skeletal muscle.
- Smooth muscle.
- Cardiac muscle.
What is the strongest muscle in the human body?
The strongest muscle based on its weight is the masseter . With all muscles of the jaw working together it can close the teeth with a force as great as 55 pounds (25 kilograms) on the incisors or 200 pounds (90.7 kilograms) on the molars.
What is the smallest muscle in the body?
Stapedius muscle is termed to be the smallest skeletal muscle in human body, which has a major role in otology. Stapedius muscle is one of the intratympanic muscles for the regulation of sound.
What part of the muscle moves the least during the contraction?
| A B | origin attached to a fixed structure or bone; moves least during contraction | insertion attached to a movable part or bone and moves most during contraction | belly central body of the muscle | prime mover muscles that produce movement in a single direction |

What is the muscle attachment to the more movable bone?
TENDONS ATTACH MUSCLE TO BONE; THE ORIGIN IS THE MORE STATIONARY BONE, THE INSERTION IS THE MORE MOVABLE BONE. 5. Tendons are attached in such a way that they PULL on the Bones and make them work like LEVERS. The movements of the Muscles and Joints enable the Bones to act as LEVERS.
