4 major parts of the skeletal system
ligaments
joints
bones
cartilage
what function is this?
bones form the internal framework that supports the body and cradles its soft organs
support
5 functions of the skeletal system
*blood cell formation
*allow movement
*protect soft organs
*storage of fat & mineral
*support the body
what function is this?
the vertebrae surround the spinal cord, and the rib cage helps protect the vital organs of the thorax
protection
what function is this?
the bones of the legs act as pillars to support the body trunk when we stand
support
what function is this?
bones protect soft body organ. ex: the fused bones of the skull provide a snug enclosure for the brain
protection
what function is this?
skeletal muscles use the bones as levers to move the body and its parts
allow movement
what function is this?
skeletal muscles attach to the bones via tendons
allow movement
what function is this?
fat is stored in the internal (marrow) cavities of the bones
storage
what function is this?
bones itself serves as a storehouse for minerals, the most important of which are calcium and phosphorus
storage
what function is this?
also called hematopoiesis
blood cell formation
what function is this?
occurs within the marrow cavities of certain bones
blood cell formation
the head of the femur contains both what?
red and yellow marrow
yellow marrow stores?
fat
red marrow is responsible for?
hematopoiesis
form new bones and add growth to existing bone tissue
osteoblasts
maintains bone tissue
osteocyte
dissolve old and damaged bone tissue so it can be replaced with new, healthier cells created by osteoblasts
osteoclasts
