(34 cards)
Axial Skeleton
Made up 80Bones
Head and trunk of vertebrate
Central axis skeleton
Supports the upright position and protects internal organs
(skull, Vertebrates, rib cage, and Sternum)
Appendicular skeleton
Made up of 126 bones
Made up of bones that supports appendages
Limbs
Aid in the movement of the body
finction #1
Supports and protection
function #2
body movement
function #3&4
produce blood cells and storage of minerals and fats
long bone
cylinder-like shape, Longer than it is wide
short bone
cube- like shape, approximatley equal in length, Width, and thickness
flat bone
thin and curved
irregular bone
Complex shape
sesamold bone
small and round embedded in tendons
epiphysis
end
diaphysis
shaft
articular cartilage
hyaline cartilage, Padding
periosteum
membrane that covers entire bone
Mendullary cavity
hollow chamber filled with bone marrow
red bone marrow
blood
yellow bone marrow
fat
compact bone tissue
wall of the diaphysis
spongy bone tissue
cancellous epiphysis, Red marrow
synovial joint
the articulating surfaces of the bones are not directly connected, But instead come into contact with each other within a joint cavity that is filled with a lubricant fluid
pivot joint
Uniaxial joint; allows rotational movement
-Atlantoaxial joint(c1-c2 vertebrae articulation proximal rediolunar joint
hinge joint
uniaxial joint, Allows flexion/ extension movement
-knee, elbow, ankle interphalangeal joint of fingers and toes
saddle joint
Biaxial joint; allows flextion/extension, abduction/adduction and circumduction movements
-First carpometacarpal joint of the thumb, Sternociavicular joint
plane joint
the multiaxial joint allows inversion and eversion of foot or flexion, extension, and lateral flexion of the vertebral column
-intertarsal joints of foot superior-inferior articular process articulations between vertebrae
