Can bone structures be different?

Can bone structures be different?

Irregular Bones Have Complex Shapes Irregular bones vary in shape and structure and therefore do not fit into any other category (flat, short, long, or sesamoid). They often have a fairly complex shape, which helps protect internal organs.

Why are bones structured differently?

Your bones are different shapes and sizes because they have different jobs to do. They are divided into four groups: Long bones. They have a diaphysis, epiphyses and a hollow centre.

Can bones move in different directions?

Movement in all directions is allowed. Saddle joint – this permits movement back and forth and from side to side, but does not allow rotation, such as the joint at the base of the thumb. Hinge joint – the two bones open and close in one direction only (along one plane) like a door, such as the knee and elbow joints.

Which race has the strongest bones?

This presentation will first review racial differences in fracture risk by sex that provide evidence to support the hypothesis that blacks have stronger bones than whites and then present data from two longitudinal observational cohort studies that demonstrate that bone mineral density, an estimate of bone mass that is …

Does race affect bone structure?

The most recent studies also demonstrate that bone structure and microarchitecture are different in ethnic groups and these variations are likely to contribute to the ethnic differences in fracture rates.

What are the four purposes of having bones?

Bones have many functions. They support the body structurally, protect our vital organs, and allow us to move. Also, they provide an environment for bone marrow, where the blood cells are created, and they act as a storage area for minerals, particularly calcium.

What is left radius?

The radius or radial bone is one of the two large bones of the forearm, the other being the ulna. It extends from the lateral side of the elbow to the thumb side of the wrist and runs parallel to the ulna.

What race has the most muscle mass?

Ethnicity effects Among the women, African Americans had the largest expected mean SM values, followed by Whites, Hispanics, and Asians. A similar pattern is present in men, in whom African American men had the largest SM and Whites the smallest SM estimates.

What race has the weakest bones?

Chinese people have lower average bone mineral density than most other racial groups, but Chinese women have lower rates of spine fractures than white women and much lower rates of hip fractures than white women.

What race has the strongest bones?

What makes up the bone give at least 10?

Bones are made up of a framework of a protein called collagen, with a mineral called calcium phosphate that makes the framework hard and strong.
