What divides an organ into superior and inferior portions?
coronal section
Which of the following is the proper description of the human body in the anatomical position?
In the anatomical position, the body is upright, directly facing the observer, feet flat and directed forward. The upper limbs are at the body’s sides with the palms facing forward.
What is a vertical section through the body dividing it into left and right called?
What is a vertical section through the body, dividing it into left and right? sagittal.
Which of the following best demonstrates the principle of complementarity of structure and function?
Which of the following best demonstrates the principle of complementarity of structure and function? Bones can support and protect body organs because they contain hard mineral deposits. For example, bones can support and protect body organs because they contain hard mineral deposits.
WHAT IS function and structure?
Structure refers to something’s form, makeup or arrangement. Function refers to something’s job, role, task, or responsibility.
What is the most common broken bone?
The collarbone, otherwise known as the clavicle, is the most commonly broken bone, thanks in large part to where it’s positioned. Located between the shoulder blade and upper ribcage, it attaches the arm to the rest of the body.
What is an example of long bone?
Long bones are mostly located in the appendicular skeleton and include bones in the lower limbs (the tibia, fibula, femur, metatarsals, and phalanges) and bones in the upper limbs (the humerus, radius, ulna, metacarpals, and phalanges).
Are bones stronger than steel?
Bone is extraordinarily strong — ounce for ounce, bone is stronger than steel, since a bar of steel of comparable size would weigh four or five times as much.
Is bone stronger than titanium?
Putting in some typical dimensions and material properties we find that the stresses in a bone made from titanium alloy, for example, would be about 1.3 times higher than in a bone of the same weight, made from bone. But the titanium alloy is 5 times stronger so obviously its safety factor is much higher.
Why do bones break if they’re so strong?
Stress fractures happen when too much pressure is placed on the same spot on a bone over long periods of time. Over time, the pressure from small impacts weakens the bone until it begins to crack along the surface. These cracks can be very small at first but get bigger and bigger if they are not given a chance to heal.
