What do the muscles that attach to the medial epicondyle control?
The medial epicondyle gives attachment to the ulnar collateral ligament of elbow joint, to the pronator teres, and to a common tendon of origin (the common flexor tendon) of some of the flexor muscles of the forearm: the flexor carpi radialis, the flexor carpi ulnaris, the flexor digitorum superficialis, and the …
What tendon attaches to the medial epicondyle?
The flexor carpi radialis and the pronator teres are the most commonly involved tendons in medial epicondylitis. The medial epicondyle also serves at the origin of the ulnar (or medial) collateral ligament (UCL). The common flexor tendon and UCL provide stability to flexion and valgus forces at the elbow.
What muscles originate at the medial epicondyle?
The medial epicondyle is the common origin of the forearm flexor and pronator muscles. The most common site of pathology is the interface between the pronator teres and the flexor carpi radialis origins.
What muscles attach to the Epicondyles at the elbow?
Musculature
| Muscle | Origin | Arteria |
|---|---|---|
| M. flexor carpi radialis | fascia antebrachii of the epicondylus medialis humeri | A. radialis |
| M. palmaris longus | fascia antebrachii of the epicondylus medialis humeri | A. recurrens ulnaris |
Which is the hardest working muscle in our body?
the heart
The hardest working muscle is the heart. It pumps out 2 ounces (71 grams) of blood at every heartbeat. Daily the heart pumps at least 2,500 gallons (9,450 liters) of blood. The heart has the ability to beat over 3 billion times in a person’s life.
What is the weakest part of the body?
Knee (This joint is arguably the weakest area of the human body).
Where are the attachments and actions of the suboccipital muscles?
Attachments: Runs from the posterior tubercle (a rudimentary spinous process) of the C1 vertebra to the medial part of the inferior nuchal line of the occipital bone. Actions: Extension of the head. Innervation : Suboccipital nerve (posterior ramus of C1). Fig 1 – The left occipital muscles, which lie underneath the deep muscles of the back.
Which is the primary action of the adductor muscles?
Primarily, the action of adductor longus is adduction of the thigh at the hip joint. It also assists in flexion and medial rotation of the femur at the hip joint. The primary action of gracilis is adduction of the thigh.
How does the direction of a muscle determine its action?
As with all muscles, the direction of the muscle’s line of pull determines the muscle’s action, and the direction of the muscle’s fibers essentially determines the line of pull. Muscles that perform flexion, extension, right lateral flexion, and/or left lateral flexion must have a vertical component to their fiber direction.
What are the muscles that bend and rotate the pelvis?
As a group, the adductors adduct, flex, and medially rotate the thigh at the hip joint and anteriorly tilt and ipsilaterally rotate (and elevate the same-side) pelvis at the hip joint. The gracilis can also flex the leg (and/or thigh) at the knee joint. The adductor magnus extends the thigh and posteriorly tilts the pelvis at the hip joint.
