yuradex [85]3 years ago

One of the contributing factor to skin color is blood. Blood is responsible for the rosy color of skin. It is influenced by how much blood flows in the capillaries, how much hemoglobin there is in the blood and the degree of oxygenation of arterial blood.

When blood is well-oxygenated the skin gives off a more reddish color or rosy color. When oxygenation is poor the skin becomes bluish, which is cyanosis.

Which of the following statements is TRUE?
erica [24]

"The origin of a muscle is attached to the bone that does NOT move" is true among the following statements.

The origin and insertion of an attachment are the points of attachment. When a muscle contracts, the point of attachment known as the origin remains stationary. As a result, when contraction occurs, the origin bone is the more immobile of the two bones at the joint.

Skeletal muscles have two or more points of attachment to bone, or occasionally to other muscles or tissues. The attachment is said to as having an origin if the location is a bone that is stationary during an action. The attachment is referred to be an insertion if the location is on the bone that moves during the motion.

The triceps brachii has four places of attachment: three origins and one insertion on the ulna (two on the humerus and one on the scapula).
