What happens during an elbow/forearm Flexion?
the angle between the forearm and arm decreases as the forearm ulna bone moves towards the humerus upper arm bone
What happens during an elbow/forearm Extension?
the angle between the forearm and arm increases as the forearm ulna bone moves away from the humerus upper arm bone

What are the 4 Major Categories OF Movements that can occur at the synovial joints (shoulder elbow, hip, knee)?
- Gliding Movements - Angular Movements - Rotational Movements - Special Movements
What is Gliding?
Gliding occurs when the surfaces of bones move past one another in a linear direction, but without significant rotary or angular movement.
What is Gliding?
Gliding occurs when the surfaces of bones move past one another in a linear direction, but without significant rotary or angular movement.
Give an example of gliding movement?
Gliding of Carpal bones when you wave ‘hello’. they primarily take place in the carpals of the wrists and the tarsals of the foot gliding occurs at the PLANE joints of the body. “Planes glide through the air.” Eg: 1. Sacroiliac joint of pelvis (hip) 2. Acromioclavicular, or AC, joint is a joint in the shoulder 3. femoropatellar joint and tibiofibular (Knee) 4. vertebrocostal joint, sternocostal joint, intervertebral joint at articular processes (exteranl ribs, spine)
What are Angular Movements?
- Flexion and Extension - Abduction and Adduction - Curcumduction (circular)
What is Flexion?
- Decreases angle between two structures. - When two structures bend or move closer together.
What is Extension?
- Increases angle between 2 structures. - When two structures bend or move away from each other.
What happens during an elbow/forearm Flexion?
the angle between the forearm and arm decreases as the forearm ulna bone moves towards the humerus upper arm bone
What happens during shoulder/arm Flexion?
Shoulder/arm Flexion is when the angle at the humourus bone of the arm and the scapula bone of the shoulder decreases (flexion) as the arms move anteriorly towards the front of body. ARMS MOVE UPWARDS AT THE FRONT OF THE BODY.
What happens during shoulder/arm Extension?
Shoulder/arm Extension is when the angle at the humourus bone of the arm and the scapula bone of the shoulder increases (extension) as the arms move posteriorly toward the back of of body. ARMS MOVE DOWNWARDS towards the anatomical postition arms at side. It can extend beyond the anatomical position & TOWARDS THE BACK OF THE BODY. the joint allows movement further back past the anatomical position behind you. anatomical position is arms beside body.
What happens during WRIST/forearm Flexion?
WRIST/forearm Flexion is when the angle at the palm of the hand and the anterior surface of the forearm (underside/bottom) decreases.
What happens during WRIST/forearm Extension?
WRIST/forearm Extension is when is when the angle at the palm of the hand and the anterior surface of the forearm (underside/bottom) increases beyond the anatomical position.
What happens during Finger/digit Flexion?
Finger/digit Flexion is when the angle between digits 2-5 and the palm decreases
What happens during Finger/digit Extension?
Finger/digit Flexion is when the angle between digits 2-5 and the palm increases
Where else can flexion and extension take place in the palm digits?
flexion and extention also take place in the interphalangeal joints between digit nuckles and palm
On which plane do we see flexion and extention?
Flexion and Extention occur withing the SAGITTAL PLANE/Lft.Rt sides/cuts down middle/midline/midsagital (sagittal suture)
SJ: Squats, lunges, forward folds, forward and back arm raises ALL SAGITTAL
Thumb/Pollex Fexion is in which plane?
Thumbs moves towards the pinky finger in the FRONTAL PLANE
Thumb Pollex extention is?
when the Thumb moves away from the pinky finger in the FRONTAL PLANE
Where can flexsion and extention occur in the thumb?
- When the thumb moves towards the pinky (in the frontal/coronal palne/splits body into front and back halves) FLEXION
- When the thumb moves away from the pinky (in the frontal/coronal palne/spits body into front and back halves) Extension
- ALSO AT THE INTERPHALANGEAL JOINTS FOR THE THUMB
