The average human has around 206 bones. Between the bones is an extensive joint system and most bones are easily movable.
– Bones themselves are quite diverse in size, length, and locations.
– Bone are the outer protection of bone marrow.
– The longest bone – femur
– The shortest bone – stapes [ear]
– Bones are not solid, they are light weight due to the spaces that are found between the tissues.
Function of Bones are as follows:
3.) Blood production
4.) Fat storage
7.) Mineral Storage
– Ligaments are “connective tissues” that hold the skeletal system together at individual joints.
– Osteoarthritis may result following surgery or when surgery is not performed.
– This is a wearing of the cartilage that leads to Arthritis.
– Joints are the location of two bones that often are dependent on a central structure.
– Joints allow movement, support, and structure to bones and ligaments.
– Skeleton function is also protection of organs and organ systems.
– Such as found under the ribcage which protects the heart, lungs, stomach and others.
– Bone marrow is another important function. The production of red blood cells (RBCs) and white blood cells (WBCs) are essential.
– Marrow is found within certain bones.
– It is a tissue in the center of the bone or also referred to as the “hollow” area of the bone
There are two types of bone marrow:
1.) Red Marrow
2.) Yellow Marrow
*** At birth – all marrow is red and overtime [age] there is an increased amount of yellow that is formed.
