MALE BONES ARE BIGGER AND STRONGER, in both size and density. Peak male bone mass is around 50% more than women’s, and women lose bone faster as we age. Black people have significantly stronger bones than whites: black women’s peak bone mass is the same as white men’s. WOMEN AND MEN HAVE THE SAME NUMBER OF RIBS.

How do we classify bones?
Bones can be classified according to their shapes. Long bones, such as the femur, are longer than they are wide. Short bones, such as the carpals, are approximately equal in length, width, and thickness. Flat bones are thin, but are often curved, such as the ribs.

How do body parts move?
Muscles move body parts by contracting and then relaxing. Muscles can pull bones, but they can’t push them back to the original position. So they work in pairs of flexors and extensors. The flexor contracts to bend a limb at a joint.
How does our brain make us move?
Muscles move on commands from the brain. Single nerve cells in the spinal cord, called motor neurons, are the only way the brain connects to muscles. When a motor neuron inside the spinal cord fires, an impulse goes out from it to the muscles on a long, very thin extension of that single cell called an axon.
How do bones help us move?
Bones also play an important role in the movement of your body, transmitting the force of muscle contractions. Your muscles attach to your bones via tendons. When your muscles contract, your bones act as a lever while your joints form a pivot point.
What is the main function of bones?
The conventional function of the skeleton is as a static structural organ supporting body movement, protecting the internal organs, and as a reservoir of minerals 2. The skeleton is an important organ for the support of the body and for the attachment of muscles and tendons, as well as body movement.
What is the function of muscles?
The muscular system is composed of specialized cells called muscle fibers. Their predominant function is contractibility. Muscles, attached to bones or internal organs and blood vessels, are responsible for movement. Nearly all movement in the body is the result of muscle contraction.
