What is the anatomical position of the hand?
This action turns the hand, wrist, and forearm almost 180 degrees so that the palm faces posteriorly or inferiorly, depending on the position of the arm. In the anatomical position, with the arms extended to the sides of the trunk and palms facing forward, the arms are already in the supinated position.
What does full supination move the hand?
Full supination moves the hand, wrist, and forearm almost 180 degrees so that the palm faces anteriorly or superiorly, depending on the position of the arm. Innerbody is the largest medical and wellness testing guide online, helping over one million visitors each month.
What is supination and pronation of the forearm?
Supination and pronation are movements of the forearm. In the anatomical position, the upper limb is held next to the body with the palm facing forward. This is the supinated position of the forearm. In this position, the radius and ulna are parallel to each other.
What is turning of the head side to side called?
Turning of the head side to side or twisting of the body is rotation. Medial and lateral rotation of the upper limb at the shoulder or lower limb at the hip involves turning the anterior surface of the limb toward the midline of the body (medial or internal rotation) or away from the midline (lateral or external rotation).
What is it called when you turn the palm downward?
• PRONATION: turning the wrist so that the palm faces downwards (or an inward rotation of the foot) • ROTATION: movement around the axis of a bone or body part. Movement towards the midline of the body is called medial (or internal) rotation; movement away from the midline is called lateral (or external) rotation.
Which motion turns the palm of the hand forward?
Supination ofMovements of the Body, Part 2 (g) Supination of the forearm turns the hand to the palm forward position in which the radius and ulna are parallel, while forearm pronation turns the hand to the palm backward position in which the radius crosses over the ulna to form an “X.” (h) Dorsiflexion of the foot at the ankle ...
What is the movement of hands called?
Flexion: Moving the palm of the hand towards the front of the forearm. Extension: Moving the back of the hand towards the back of the forearm. Adduction: Moving the pinky side of the hand toward the outer aspect of the forearm. Abduction: Moving the thumb side of the hand toward the inner aspect of the forearm.

What are the two kinds of hand positions?
There are two basic release positions, one for a straight ball and one for a hook ball. Generally, the straight release is passive; the hand and forearm do not move at the release point.
What is hand gesture?
a motion of the hands, head, or body to emphasize an idea or emotion, esp while speaking. something said or done as a formality or as an indication of intentiona political gesture.
What movement is characterized as the rotation of the arm to the palm facing up?
SupinationSupination - The opposite of pronation, the rotation of the forearm so that the palm faces anteriorly, or palm facing up. The hand is supine (facing anteriorly) in the anatomical position. (See also Supinator muscle.)
What is pronation of hand?
Supination and pronation are terms used to describe the up or down orientation of your hand, arm, or foot. When your palm or forearm faces up, it's supinated. When your palm or forearm faces down, it's pronated.
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 is an example of adduction?
For fingers or toes, adduction brings the digits toward the center of the hand or foot. For example, if a person has their fingers spread wide apart, bringing them together would be adduction. Closing arms to the chest or bringing knees together are other examples of adduction.
What is the term for the movement of the fingers around the long axis?
Therefore, abducting the fingers spreads them out. Medial and Lateral Rotation . Medial and lateral rotation describe movement of the limbs around their long axis: Medial rotation is a rotational movement towards the midline. It is sometimes referred to as internal rotation.
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 movement of the hip called?
Adduction is a movement towards the midline. Adduction of the hip squeezes the legs together.
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.
How to do supine position?
With your hand resting on a table in front of you, and keeping your shoulder and elbow still, turn your hand onto its back, palm up. 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.
How to rotate your hips?
Firstly, with a straight leg, rotate it to point the toes inward. This is medial rotation of the hip. Secondly, imagine you are carrying a tea tray in front of you, with elbow at 90 degrees. Now rotate the arm, bringing your hand towards your opposite hip (elbow still at 90 degrees).
What is medial rotation?
Medial rotation is a rotational movement towards the midline. It is sometimes referred to as internal rotation. To understand this, we have two scenarios to imagine. Firstly, with a straight leg, rotate it to point the toes inward. This is medial rotation of the hip. Secondly, imagine you are carrying a tea tray in front of you, with elbow at 90 degrees. Now rotate the arm, bringing your hand towards your opposite hip (elbow still at 90 degrees). This is internal rotation of the shoulder.
Which part of the body moves the anterior surface of the arm or thigh toward the midline?
Here, the humerus and femur rotate around their long axis, which moves the anterior surface of the arm or thigh either toward or away from the midline of the body. Movement that brings the anterior surface of the limb toward the midline of the body is called medial (internal) rotation.
Which joint is lateral rotation?
Be sure to distinguish medial and lateral rotation, which can only occur at the multiaxial shoulder and hip joints, from circumduction, which can occur at either biaxial or multiaxial joints. Turning of the head side to side or twisting of the body is rotation.
What are the anterior and posterior motions of the upper limb?
For the upper limb, all anterior-going motions are flexion and all posterior-going motions are extension. These include anterior-posterior movements of the arm at the shoulder, the forearm at the elbow, the hand at the wrist, and the fingers at the metacarpophalangeal and interphalangeal joints.
What are the learning objectives of synovial joints?
Identify the joints that allow for these motions. Synovial joints allow the body a tremendous range of movements. Each movement at a synovial joint results from the contraction or relaxation of the muscles that are attached to the bones on either side of the articulation.
What is the term for the abnormal or excessive extension of a joint beyond its normal range of motion?
Hyperextension is the abnormal or excessive extension of a joint beyond its normal range of motion, thus resulting in injury. Similarly, hyperflexion is excessive flexion at a joint. Hyperextension injuries are common at hinge joints such as the knee or elbow.
Where does circumduction take place?
Adduction, abduction, and circumduction take place at the shoulder, hip, wrist, metacarpophalangeal, and metatarsophalangeal joints.
Which plane of motion is flexion and extension?
Figure 1. Flexion and extension. (a)– (b) Flexion and extension motions are in the sagittal (anterior–posterior) plane of motion. These movements take place at the shoulder, hip, elbow, knee, wrist, metacarpophalangeal, metatarsophalangeal, and interphalangeal joints. (c)– (d) Anterior bending of the head or vertebral column is flexion, while any posterior-going movement is extension.
What is the band on the palm?
The nodules of tissue on the palm gradually stretch into thin bands of collagen. These collagen bands progressively extend up, usually into the ring and pinky fingers. As the bands tighten, they pull the fingers in toward the palm and make it difficult to straighten out your fingers.
What is the condition that causes the skin under the palm to thicken and become scar-like?
Dupuytren's (du-pwe-TRANZ) contracture is a condition that gradually causes connective tissue (fascia) under the skin of your palm to thicken and become scar-like. Although Dupuytren's isn't always painful, it does restrict movement.
What Causes Dupuytren's Contracture?
Although reports of Dupuytren's contracture first appeared in medical literature in the 1600s, doctors still don’t know what causes the scar tissue to form. The condition tends to run in families, so genes may be involved. Dupuytren's is more common in middle age, especially in men of Northern European descent. Alcohol and tobacco use, diabetes, and epilepsy also increase the risk.
How does the skin on your palm feel?
First, the skin on the palm of the hand starts to thicken. The skin might appear puckered as knots (nodules) of hard tissue begin to form on your palm. These nodules might feel tender to the touch, but they’re usually not painful. The thickening of the skin usually happens very slowly.
How to get your fingers back after contracture?
If contracture symptoms are bad enough to interfere with daily life, surgery may help. During the procedure, your surgeon removes the thickened tissue in your palm, which allows the fingers to move again. Surgery usually can give you normal movement back, but risks may include infection and nerve damage.
What is it called when your fingers curl?
The bending caused by the thick tissue is called contracture. Swipe to advance.
How to fix a broken band in your hand?
Then your hand is moved by your doctor until the bands are broken and your fingers can be straightened. Other treatments may include needle aponeurotomy, where the contracted bands are divided with small hypodermic needles. Radiation therapy is also being studied as a treatment and has been successful in several small studies.
