Muscles Used When Throwing in a Ball
Rectus abdominis (abs)
ball and socket
Type of Joint & Movement
The wrist joint is formed by:
• Distally – The proximal row of the carpal bones (except the pisiform).
• Proximally - The distal end of the radius, and the articular disk
The Wrist: continued
Movements of the Wrist
-Ellipsoid type synovial joint, allowing for movement along two axes.
-All the movements of the wrist are performed by the muscles of the forearm.
Flexion - Produced mainly by the flexor carpi ulnaris, flexor carpi radialis
Extension - Produced mainly by the extensor carpi radialis longus, and extensor carpi ulnaris, with assistance from the extensor digitorum.
Adduction - Produced by the extensor carpi ulnaris and flexor carpi ulnaris
Abduction - Produced by the abductor pollicis longus, flexor carpi radialis, extensor carpi radialis longus
The Wrist: Continued
What type of lever is the wrist joint?
Third Class Lever
• force is placed between the axis and resistance
-the effort placed between the load and the fulcrum. The effort always travels a shorter distance and must be greater than the load.-
Possible Injuries & Treatment
The Wrist: Continued
Suffer from rotator cuff injuries
Tear or strain muscles in the arm/leg
:Bones of the Wrist
One reason that the wrist is so
complicated is because every
small carpal bone forms a joint
with the bone next to it.
This means that what we call
the wrist joint is actually made
up of many small joints.
Articular cartilage is the material
that covers the ends of the bones
of any join, very thin layer on
It is extremely important to properly warm up and stretch before playing (any sport)
physical therapy depending on intensity of injury
The Wrist: Ligaments
Three important ligaments support the sides of the wrist. These are the collateral ligaments. There are two collateral ligaments that connect the forearm to the wrist, one on each side of the wrist.
the ulnar collateral ligament-
crosses the ulnar edge
(the side away from the thumb)
transverse carpal ligament-
a thick band of tissue that crosses in
front of the wrist
radial collateral ligament - prevents
the wrist from bending too far to the side
the triangular fibrocartilage complex - a small cartilage
pad that cushions this part of the wrist joint &
improves the range of motion and gliding action
within the wrist joint.

The Wrist: Tendons
flexor tendons - cross the palm side of the wrist, curl the fingers and thumb, and they bend the wrist
extensor tendons - travel over the back of the wrist, run through a series of tunnels, called compartment (compartments are lined with a slick substance called tenosynovium, which prevents friction as the extensor tendons glide inside their compartment.)
The Wrist: Muscles
The tendons that cross the wrist begin as muscles that start in the forearm.
Capable of Flexion, Extension, Adduction, & Abduction
The wrist muscles generally start further up in the forearm. The tendons of these muscles cross the wrist. They control the actions of the fingers, thumb, and wrist.
