Scientific Name Of Joint Essay

Humerus, Radius, Ulana (arms): To support your wrist and fingers when hitting the ball, it also provides power when hitting the ball.

In this phase the athlete is standing in a neutral position holding the ball. The metatarsophalangeal and interphalangeal (great and lesser toes) are held at slight flexion pressed against the ground by an isometric contraction of the flexor halluces longus, flexor digitorum longus, flexor digitorum longus. The ankle is plantar flexed using an isometric contraction of the gastrocnemius and the soleus. The tibiofermoral (knee) joints are slightly flexed by a isomectric contraction of the quadriceps muscles (rectus femoris, vastus lateralis, vastus medialis, vastus intermedius). The acetabularfemoral (hip) joint is held at a postion of slight flexion through an isometric contraction of the biceps femoris, pectineus, iliacus, and the psoas. The intervertebral (lumbar) joint is extended by an isometric contraction using the erector spinae. The atlantooccipital (cervical spine) joint is flexed by an isometric contraction erector spinae. Both scapulothroracic (shoulder girdle) joint is protracted by an isometric contraction of the serratus anterior and pectoralis minor. The glenohumeral (shoulder) joint is at internal rotation by an isometric contraction using the pectoralis major, latissimus dorsi, teres major, and the subscapularius. The humeroulnar (elbow) joint is at 90 degrees of flexion by an isometric contraction using the biceps brachii, brachioradialis, and brachialis. The radiocarpal (wrist left and right)

Ulnar collateral ligament injury is a type of elbow injury that develops from repeated overhand throwing movements (overuse). This motion places a lot of stress on the two strong bands of tissue (ligaments) that hold your elbow joint in place. The ulnar collateral ligament (UCL) is a main ligament located on the inside of your elbow. Over time, repetitive overhand throwing can damage the UCL.

6. Identify the movements associated with the arm, forearm, wrist, and fingers. Rotation, flexing, extension, hyperextension, proation, and supination.

Anconeus - It's attachments are the lateral epicondyle of humerus, olecranon process of ulna, and ulna blade. When it contracts

A torn elbow ligament is the most common area to have an injury. The locations were it happens is in the inside of the elbow joint.

Once inside the elbow the unlar nerveis recognized, lifted out, and moved to provide greater access to the joint. This is the "funny bone" nerve and it runs inside the ulnar groove.

Shoulder flexion/extension; Elbow flexion and extension; Use of the lower and upper back. Muscles involved include the latissimus dorsi, rhomboids, trapezius, deltoids and the pectorals.

Ligament - Ligaments determine how much the joints can move so each joint is stabilized.

For the human joint anatomy project, our group decided to research and construct the elbow joint. The following is a report and summary of the project including roles taken, challenges faced, solutions derived, and ultimately, contribution and experiences of both partners.

Joints are the connecting points where two bones meet. They allow the human body to be flexible. Muscles are also necessary for movement. They pulls bones are allow them to move. Tendons attach muscles to bones while ligaments attach bones to bones. The central nervous system stimulates muscles to contract when they are stimulated by “messages”, or impulses, that are sent from motor nerves and the bursae are fluid filled sacs between joints that provide protection

There are about 600 muscles in the body working together to create movement. Muscle contractions pull both ends of the muscle towards one another. One bone attached to each muscle is always more stabilized than the other. The less stabilized bone moves during muscle contraction due to the weaker stability. The points of attachment determine which bone will move. The least movable part is called the origin; it is the part that attaches closer to the midline of the body. This leaves the most movable part called the insertion. Each of these points can be identified in individual muscles to assist trainers in understanding how the muscles and joints work together to create motion.

There are six primary movements that occur at the joints between the body segment; flexion, extension, abduction, adduction, rotation, and circumduction.

The shoulder is a ball and socket joint which allows it a flexion and extension motion.

(While some of the following muscles act upon more than one joint, the only actions that will be listed are those pertaining to the knee.)
