Bones
Gives support and shape to the body, stores mineral salts
Oste/o
Bone
Periosteum
Fibrous protective membrane that is around the bone
Compact Bone
Hard, dense bone material found in the outer layer of bone
Cancellated / Spongy bone
Inner, spongy lattice like structure with spaces filled with marrow
Medullary Cavity
Innermost part that contains marrow
Epiphyses
End of the developing bone and the shaft
Diaphyses
Shaft of the bone, composed of compact bone
Articular Cartilage
Covers the ends of the bones
Bones grow how?
From the epiphyseal line, the growth plate.
Osetoblasts
Immature bone cells
Osteocytes
Mature bone cells
Osteoclast
Large cells on the bone
Long Bones
Femur and Radius
Short Bones
Carpus and Tarsus (shock absorbers)
Flat Bones
Ribs and Pelvis
Pneumatic Bones
Contains Sinuses
Irregular Bones
Veterbrae and Inner Ear
Sesamoid
Skull
Axial Skeleton
Skull, neck,vertebrae,ribs, sternum
Appendicular
Shoulder, arms and legs
Facial Bones
Maxilla- Upper Jaw
Mandible- Lower Jaw
Veterbrae Column
Shelters the spinal cord, supports thorax and skull
Cervical Veterbrae
Neck, first bone is called the atlas supports the skull
Thoracic Veterbrae
Chest, where the ribs attach
Lumbar
Lower back , supports the abdomen
Sacrum
Pelvis
Coocygeal
Caudal or Tail
Intervertebral Foramen
Spinal nerves emerge from the spinal Column
Intervertebral Discs
Serve as a joint to allow slight movement, holds ligaments together and functions as a shock absorber
Hemilaminectomy
Removes layer of veterbrae, and removes disc contents
Cost/o
Rib
Ribs
Flat bones attached to dorsal veterbrae, true ribs - attached to cartilage, floating ribs do not attach
Breastbone
Composed of series of flat bones and cartilage

Arth
Joints
Synarthroses
Permit no movement, contain fibrous tissue that unties bones. (Bones in the skull)
Amphisrthroses
Allows for slight movements
Cartilaginous
Contains cartilages that is attached to bone
Diathroses
Permits full movement
Hinge Joint
Movement in one direction
Ball and socket
Rounded head fits into joint
Synovial fluid
Acts as lubricant, more mobility
Gliding
Joint surfaces are flat
Pivot
Joints move in pivot like motion
Myo
Word part for muscle
Sarcomere
Basic contractile unit of muscle cell
Myosin
Pulls acting fibers toward the middle shorten the length of the muscle
Fascia
Sheet of fibrous membrane that closes muscles and snakes groups
Ligaments
Connects bones or cartilage
