Axial Region: Bones and Bone Markings Flashcards
(28 cards)
functions of the skeletal system
support protection for organs and systems anchorage (origins, insertions) mineral and growth factor storage bone cell formation RBC and WBC made in red bone marrow in flat bones triglyceride storage
osteocyte
bone cell
osteocalcin
hormone for improved cognitive function
has a neuroprotective effect in animals
functions of the skeletal system
support protection for organs and systems anchorage (origins, insertions) mineral and growth factor storage bone cell formation RBC and WBC made in red bone marrow in flat bones triglyceride storage in the yellow marrow in long bones hormone production
what type of tissue is bone
living and dynamic
bone markings
dents and bumps on bones
in response to pressure
orbits
eye sockets
axial skeleton
forms the long axis of the body
the skull, the vertebral column, and the thoracic cage
supports the head, neck, and trunk
protects the brain, spinal cord, and organs in the thorax
appendicular skeleton
the bones of the upper and lower limbs
includes pectoral and pelvic girdles that attach the limbs to the axial skeleton
sutures
interlocking, immovable joints
suture lines have an irregular, saw-toothed appearance
cranial cavity
the cavity occupied by the brain
foramen
hole or opening in a bone or between body cavities
fossa
a depression
often a joint surface
fissure
a groove or cleft
periosteum
Membrane of fibrous connective tissue that covers the external surface of bones of the skeleton
epiphysis
The end of a long bone, attached to the shaft
epiphyseal plate
Plate of hyaline cartilage at the junction of the diaphysis (shaft) and epiphysis (end) of most bones in the growing skeleton; provides growth in the length of the bone
diaphysis
elongated shaft of a long bone
hematopoiesis
blood cell formation
epiglottis
A leaf-shaped piece of elastic cartilage that extends from the posterior surface of the tongue to the larynx; covers the opening of the larynx during swallowing
larynx
Cartilaginous organ located between the pharynx and trachea; contains the vocal cords; the voice box
intervertebral discs
The discs between the vertebrae of the spinal column; each consists of fibrous rings surrounding a springy core.
tendon
Cord of dense regular connective tissue that attaches muscle to bone
sinus
(1) Mucous-membrane-lined, air-filled cavity in certain bones of the face; (2) dilated channel for the passage of blood or lymph.
