Bone is a type if what tissue?
Connective
What is responsible for building new bone tissue?
Osteoblasts
What is responsible for decomposing old bone tissue?
Osteoclasts
What is responsible for maintaining bone tissue?
Osteocytes
What is bone made up of?
Calcium crystals and Collagen
Calcium crystals descriton
Very hard, withstands compression, inflexible and brittle
Collagen description
Protein, adds flexibility
What are the two types of bone tissue?
Compact and cancellous
Where is compact muscle tissue found?
Outside of the bones, often where muscle attaches to bone - thus very hard dense strong and HEAVY.
Describe Cancellous bone tissue
Found interior of bones, looks like sponge, allowing for strength without unnecessary weight.
What division of the Skelton contains the skull, thoracic cage (rib cage), and vertebra column (spine)?
Axial Skeleton
What division of the skeleton contains the pectoral girdle (shoulder), upper limbs, pelvic girdle (pelvis) and lower limbs?
Appendicular Skeleton
What do you classify thin curved bones (ie, skull)?
Flat Bones
What do you classify bones that are longer than they are wide (femur, thigh)?
Long Bones
What do you classify bones that are short and boxy (feet)?
Short bones
What do you classify bones with complex shapes and foramen?
Irregular
Foramen
Holes
Articulation
Where bones meet
What are the three types of joints?
Synovial Joints, Fibrous Joints, Cartilaginous Joints
What are fibrous joints made of?
Dense Fibrous Tissue - which can develop into bone overtime (i.e., infant skull)
What are fibrous joints function?
High stability (no mobility)
What are cartilaginous Joints made of?
Fibrocartilage (a layer of cartilage between bones)
What is the function of cartilaginous joints?
They are primarily for strength, but allow for some small movement
Example of a cartilaginous joint
Pubic Symphysis, invertebral discs.
