Unit 8: Physiology of Human Body Systems – Assignment A
Musculoskeletal disorders
As a support mechanism for the body, the skeletal system acts. It gives the body its form, facilitates
motion, creates blood cells, preserves organs and stores minerals. /Often called the musculoskeletal
system/ the skeletal system is.
The skeletal system is the core mechanism of the body. It consists of cartilage, tendons and
ligaments, plus bones and connective tissue. It's named the musculoskeletal organ as well.
What does the skeletal system do?
There are several roles in the skeletal system. Besides granting us our human type and traits, it can:
Allows movement: To help you balance and walk, your spine maintains your body weight. In order to
make the body parts mobile, joints, connective tissue and muscles work together.
Blood cells are produced: Bones contain bone marrow. In the bone marrow, red and white blood
cells are formed.
Protects and supports organs: your skull protects your brain, your heart and lungs are covered by
your ribs, and your backbone protects your spine.
Stores nutrients: Bones preserve the supply of minerals such as calcium and vitamin D to the body.
What are the parts of the skeletal system?
A network of several different pieces that work together to help you travel is the skeletal structure.
The key portion of your skeletal system consists of the bones, rigid frameworks that form the
backbone of the body, the skeleton. In an adult human skull, there are 206 bones. There are three
principal layers of each bone:
Periosteum: The periosteum is a tough membrane which covers the outside of the bone and
protects it.
Compact bone: The compact bone below the periosteum is white, rigid, and smooth. It offers
institutional support and defence.
Spongy body: The bone's inner core layer is thinner than the compact bone. To store marrow, it has
tiny holes called pores.

o vertebral column (cervical, thoracic and lumbar vertebrae, sacrum and coccyx, intervertebral discs)
o ribs and sternum.
Appendicular skeleton:
o limb bones (humerus, radius, ulna; femur,
patella, tibia, fibula)
o wrist, hand and digit bones (carpals,
metacarpals, phalanges)
o ankle, foot and digit bones (tarsals,
metatarsals, phalanges, calcaneus)
o shoulder girdle (scapula, clavicle)
o pelvic girdle (ilium, pubis, ischium).
Bone types
Long bone
Hard, compact bones that include strength, stability and mobility are long bones. A long bone is the
bone of the thigh (femur). There's a long bone with a shaft and two ends which contains Yellow bone
marrow and red bone marrow, producing blood cells, are found in long bones.
