Exoskeleton

Endoskeleton
Skeleton embedded with the muscle
Axial Skeleton
Skull, ribs, vertebrae, sternum

Heterotrophic bones
bones embedded in the organs
Os rostrale

Ossa cordis
bones in the heart of cattle, sheep, and goats
Os Phrenic
bones in the diaphragm of camels
Ossa penis
Bones in the penis of carnivores (dogs, cats) and rodents
Secleral rings

Hyoid apparatus
found in the tongue of avians and mammals
Origin
End of the muscle that is attached to a stationary part of the bone
Insertion
the end of the muscle that is attached to a mobile section of the bone
Tendons
attach muscles to bones
Ligaments
attach bone to bone
Epiphysis
two ends of the long bone
Diaphysis
the shaft of the long bone
Epiphyseal-Diaphyseal plate
Growth plate
Endosteum
membrane lining the medullary cavity
Periosteum
membrane covering the surface of the bone
Medullary cavity
Hollow area in the center where bone marrow is located. sticky and waxy in feeling
Dipole
Spongy bone
Long Bone
dumb bell shaped found in limbs (ulna, radius)
Flat Bone
flat in two dimensions (skull bones, ribs)
Short bone
Cubical in shape. Typical shortbones: wrist
Sesamoid: look like sesame seed: patella
Functions: Reduce concussion and friction
Irregular bones
vertebrea
Pneumatic bone
Contain spaces filled with air: paranasal sinuses
