What type of body movement occurs in the lower leg?
In the lower limb, bringing the thigh forward and upward is flexion at the hip joint, while any posterior-going motion of the thigh is extension. Note that extension of the thigh beyond the anatomical (standing) position is greatly limited by the ligaments that support the hip joint.
What is the end of the muscle that connects to the bone that moves when the muscle contracts?
The moveable end of the muscle that attaches to the bone being pulled is called the muscle’s insertion, and the end of the muscle attached to a fixed (stabilized) bone is called the origin.
What is the end of the muscle that connects to the bone that does not move?
The end of the muscle that is connected to the bone that does not move is called the origin. The end connected to the bone that moves when the muscle contracts is called the insertion.
Which of the following describes inversion and eversion?
Which of the following best describes eversion and inversion? an outward turning of the sole of the foot, and an inward turning of the sole of the foot.
What are the 3 types of movement?
The different types of movement that are permitted at each joint are described below.
- Flexion – bending a joint.
- Extension – straightening a joint.
- Abduction – movement away from the midline of the body.
- Adduction – movement towards the midline of the body.
- Circumduction – this is where the limb moves in a circle.
What are the 2 types of body movements?
- Flexion and Extension. Flexion and extension are movements that take place within the sagittal plane and involve anterior or posterior movements of the body or limbs.
- Abduction and Adduction.
- Circumduction.
- Rotation.
- Supination and Pronation.
- Dorsiflexion and Plantar Flexion.
- Inversion and Eversion.
- Protraction and Retraction.
What attaches muscles to bone?
A tendon is a fibrous connective tissue which attaches muscle to bone. Tendons may also attach muscles to structures such as the eyeball.
Can both ends of a muscle be attached to a bone that is responsible for movement?
Most skeletal muscle is attached to bone on its ends by way of what we call tendons. As the muscles contract, they exert force on the bones, which help to support and move our body along with its appendages. In most cases, one end of the muscle is fixed in its position, while the other end moves during contraction.
Why do muscles always work in antagonistic pairs?
However, muscle contraction cannot act to push the bone back into its original position, and because of this, muscles work in ‘antagonistic muscle pairs‘. One muscle of the pair contracts to move the body part, the other muscle in the pair then contracts to return the body part back to the original position.
What are the 4 common traits of all muscles?
All muscle tissues have 4 characteristics in common:
- excitability.
- contractility.
- extensibility – they can be stretched.
- elasticity – they return to normal length after stretching.
What part of the muscle moves the least during contraction?
Ch. 7 Muscular System Vocabulary Terms (14-15)
| 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 |
Which type of joint allows for the most movement?
Synovial joints are capable of the greatest movement of the three structural joint types; however, the more mobile a joint, the weaker the joint. Knees, elbows, and shoulders are examples of synovial joints. Since they allow for free movement, synovial joints are classified as diarthroses.
What best describes the movement called eversion of the foot?
Inversion and eversion
Eversion is the movement of the sole of the foot away from the median plane. Inversion is the movement of the sole towards the median plane. For example, inversion describes the motion when an ankle is twisted.
What is eversion movement?
Eversion involves the movement of the sole away from the median plane – so that the sole faces in a lateral direction.
What is Circumduction movement?
Circumduction is the orderly combination of shoulder movements so that the hand traces a circle and the arm traces a cone. In order it is produced by shoulder flexion, abduction, extension and abduction (or the reverse).
