give functions of musculoskeletal system
MPBSS
movement
protection of internal organs
blood cell production
structural support
storage of minerals
how many bones in the body
206
bones found in the upper and lower extremities
long bones
irregularly shaped bones located in the ankle and hand
short bones
located where extensive protection of underlying structures is needed
flat bones
vertebrae and bones of the jaw
irregular bones
acts as a lubrication and shock absorption
synovial fluid
muscle are divided into three:
epimysium
fascicles
endomysium
upon/over the muscles
epimysium
this muscles is also called as ‘’bundles”
fascicles
fascicles is surrounded by a connective tissue called the
perimysium
within the muscles
endomysium
what part of the bone contains red marrow
spongy bone
it is where the hematopoiesis occurs
red marrow
the formation of blood cells
hematopoiesis
Yellow marrow is located in the ______
diaphysis
contains stem cells that will become later on your cartilage, fats, or bones
yellow marrow
contains the epiphyseal plate (or called as growth plate)
metaphysis
cells function in bone formation
osteoblast
mature bone cells that function in bone maintenance
osteocytes
bone destroying cells; removes necrotic bones
osteoclast
multinuclear cells function in destroying, resorbing, and remodeling bone
osteoclast
process of bone formation
osteogenesis
the process of formation of the bone matrix and deposition of minerals
ossification
helps in the absorption of calcium
vitamin D
regulating factors for bone formation
stress and weight bearing
vitamin D
parathyroid hormone and calcitonin
blood supply
it will bring the calcium out of the bone into the bloodstream
parathyroid hormone
counteracts the activity of the parathyroid hormone
calcitonin
Is the following statement true or false?
Bone is in a constant state of turnover.
true
what is the role of calcium
muscle contraction
