The major structures of bones include the diaphysis (the long shaft), epiphysis (the ends of the bone), and metaphysis (the region between diaphysis and epiphysis). Bones are categorized into two main types: compact bone, which is dense and forms the outer layer, and spongy bone, which is porous and found mainly in the interior. Additionally, bones are classified based on their shape into long, short, flat, and irregular bones. Each type has unique functions and structural characteristics suited to their roles in the body.
The major organs of the skeletal system are bones, cartilage, tendons, and ligaments. Bones provide structure and support to the body, protect internal organs, and assist in movement. Cartilage cushions joints and helps maintain their flexibility, while tendons connect muscles to bones and ligaments connect bones to bones.
The major structures of the muscular system highlight the skeletal muscles. These are the muscles involved with contracting and moving body parts. The smooth muscles are the domain of the subconscious mind, (most organs). The tendons and ligaments connect the bones together as well as the muscles to the bones. And Adipose tissue is a connective tissue that stores fat and cushions joints.
The major structures of the muscular system include skeletal muscles, which facilitate voluntary movements and support posture; smooth muscles, which are found in the walls of internal organs and control involuntary movements; and cardiac muscle, which makes up the heart and is responsible for pumping blood. These muscles work in conjunction with tendons, which attach muscles to bones, and ligaments, which connect bones to other bones, enabling coordinated movement throughout the body.
The major bones of the arms are the humerus, radius, and the ulna. These are long bones that have tubular shaft and articular surface at each end.
There are 206 major bones in the adult human body. These bones are grouped into the axial skeleton (80 bones, including the skull, vertebral column, and ribs) and the appendicular skeleton (126 bones, including the limbs and pelvis).
The major bones in the skull are as follows:FrontalParietalOccipitalTemporalSphenoidMandibleZygomaticVomerEthmoidMaxillaLacrimalNasalSee http://en.wikipedia.org/wiki/Human_skull for more detail
The major circulatory system structures are the heart, arteries, arterioles, capillaries and veins.
The two main groups are Catholic and Protestant. These split into many subcategories, but these are the main two.
I know that what attaches bones to muscles is called TENDONS
