Which term describes movement that decreases the angle between two structures?
Flexion is a body movement term that decreases the angle between two structures, resulting in the structures bending or moving closer together. 2. Which statement describes extension? a. Movement that increases the angle between two structures, causing the structures to straighten or move apart b.
What is an antagonistic movement in anatomy?
As for anatomical terms of location, the terms used assume that the body starts in the anatomical position. Most movements have an opposite movement, otherwise known as an antagonistic movement. The terms are described here in antagonistic pairs for ease of understanding.
What are anatomical terms of movement?
Anatomical terms of movement are used to describe the actions of muscles on the skeleton. Muscles contract to produce movement at joints, and the subsequent movements can be precisely described using the terminology below.
What is the definition of flexion in anatomy?
The answer is b. Flexion is a body movement term that decreases the angle between two structures, resulting in the structures bending or moving closer together. 2. Which statement describes extension?
What term describes straightening or increasing the angle between bones?
In the limbs, flexion decreases the angle between the bones (bending of the joint), while extension increases the angle and straightens the joint.
What is the term for a straightening that increases the joint angle?
Extension. The opposite of flexion is extension, which refers to the straightening of a joint. In other words, flexion works to shorten a joint angle while extension works to increases it.Jan 15, 2020
What is the act of increasing the angle between two bones?
Flexion/Extension The movement at a joint which decreases the angle between two adjacent body segments is know as flexion. The opposite action is extension, where the angle between body segments is increased.
Which term describes a decrease in an angle between two bones?
Flexion. Decreases the angle between two bones.May 18, 2020
When your muscles straighten a joint it is called?
when your muscles straighten a joint, it is called. extension.
What is a ligament?
A ligament is a fibrous connective tissue that attaches bone to bone, and usually serves to hold structures together and keep them stable.Aug 13, 2020
What is the term for straightening out a limb?
extension. Straightening out a limb or joint. abduction.
Which term describes straightening a body part?
Flexion. This movement is the bending of a part, or decreasing the angle between two parts. Extension. The opposite of flexion is extension, the straightening of a part, or increasing the angle between two parts.
What is an example of flexion?
Flexion – bending a joint. This occurs when the angle of a joint decreases. For example, the elbow flexes when performing a biceps curl. The knee flexes in preparation for kicking a ball.
What refers to increasing the angle of the joint thus moving two bones farther apart?
Extension. The reverse of flexion, involves movement along the sagittal plan that INCREASES the angle between the articulating bones.
What is it called when you straighten the lower leg away from the upper leg?
abduction. Straightening the lower leg away from the upper leg. extension. Increasing the angle between two bone.
What is the term for a decrease in relative angle between two body parts?
Flexion. refers to a movement that decreases the angle between two body parts. Flexion at the elbow is decreasing the angle between the ulna and the humerus.
What is the term for the movement of a limb extending from the joint at which the movement is controlled?
Circumduction . Circumduction can be defined as a conical movement of a limb extending from the joint at which the movement is controlled. It is sometimes talked about as a circular motion, but is more accurately conical due to the ‘cone’ formed by the moving limb.
What is the movement of the foot around its long axis called?
Inversion and Eversion . Inversion and eversion are movements which occur at the ankle joint, referring to the rotation of the foot around its long axis. Inversion involves the movement of the sole towards the median plane – so that the sole faces in a medial direction.
What is the difference between dorsiflexion and dorsiflexion?
They refer to the two surfaces of the foot; the dorsum (superior surface) and the plantar surface (the sole). Dorsiflexion refers to flexion at the ankle, so that the foot points more superiorly. Dorsiflexion of the hand is a confusing term, and so is rarely used.
What is the movement of the scapula on the thoracic wall that allows the shoulder to move
Protraction describes the anterolateral movement of the scapula on the thoracic wall that allows the shoulder to move anteriorly. In practice, this is the movement of ‘reaching out’ to something.
What is the term for lying flat on the back?
These terms also apply to the whole body - when lying flat on the back, the body is supine. When lying flat on the front, the body is prone. Dorsiflexion and Plantarflexion. Dorsiflexion and plantarflexion are terms used to describe movements at the ankle.
What is the movement of the back when lying flat on the back?
This is the supine position, and so this movement is supination. Again, keeping the elbow and shoulder still, flip your hand onto its front, palm down. This is the prone position, and so this movement is named pronation. These terms also apply to the whole body – when lying flat on the back, the body is supine.
What is the movement of the thumb and little finger?
Opposition brings the thumb and little finger together. Reposition is a movement that moves the thumb and the little finger away from each other, effectively reversing opposition. Circumduction. Circumduction can be defined as a conical movement of a limb extending from the joint at which the movement is controlled.
Which plane of the body is flexion and extension?
The transverse plane. The answer is c, the sagittal plane. Flexion and extension are often taking place within (or parallel to) the sagittal plane. There are some exceptions, however. Flexion and extension of the thumb or lateral flexion and extension of the spine are examples of flexion and extension taking place within the frontal plane.
Which plane does thumb flexion take place in?
Both a and b. The answer is a. Flexion for the thumb has it moving toward the pinky, and the movement takes place within the frontal plane, not the sagittal plane like most other movements of flexion and extension.
