True
joint kinesthetic receptors
Look in the mirror, on the outside of your elbow. The slang term weenis (or wenis) is the loose skin covering the tip of the elbow. This is more properly referred to as olecranal skin.
Flexion when you pull your forearm towards your body and extension when you extend it away from your body.
Some animals have similar anatomical structure to that of humans. The humerus is the upper arm bone in humans extending from the shoulder to the elbow.
False
because the blood vessles by your elbow get pinched by the bending so less blood flows
Biceps Brachii
True
To raise your hand in class, by bending your arm at the elbow.
It either expands or contracts depending on which way you're bending your elbow.
joint kinesthetic receptors
Most commonly, trauma to the elbow or repetitive bending of the elbow puts pressure on the ulnar nerve that damages the myelin sheath insulating and protecting the nerve.
yes because it allows the arm to move back and forth, like a door hingeThe elbow is a hinge joint.The elbow joint is a hinge joint.
Flexion (same as bending) at the elbow joint (between the humerus and the radius and ulna) is mainly achieved by the Brachialis Muscle. This is not the answer most would expect as everyone knows the Biceps Brachii (Biceps of the arm) are what flexes this joint. In fact the biceps does both supination and flexion of the elbow because its insertion is on the radius. Only when the forearm is supinated, the biceps is able to assist the deeper and more powerful brachialis muscle with the flexion of the elbow.
Generally a sore elbow. Sometimes, there may be a bump on the outside of the elbow and when hitting a one-handed back-hand, the elbow may hurt. Causes include hitting one-handed backhands, using topspin, improper form or overuse.
The primary function of the biceps is to supinate the hand. Secondary functions are bending the arm around the axis of the elbow and raising the elbow above the shoulder.(Source: Arthur Jones)
