bone tissue
ossification
process of bone formation
osteoblast
bone cell that helps form bony tissue
osteoclast
bone cell that absorbs and removes unwanted bony tissue
periosteum
membrane surrounding bones; rich in blood vessels and nerve tissue

depression in the sphenoid bone where the pituitary gland is located
sinus
hollow air cavity within a bone
styloid process
pole-like process extending downward from the temporal bone on each side of the skull
suture
immovable joint between bones, such as the skull
temporomandibular joint
connection on either side of the head between the temporal bone of the skull and mandibular bone of the jaw
trabeculae
supporting latticework of bony fibers in cancellous bone
trochanter
a rough prominence at the upper part of the femur of many vertebrates serving usually for the attachment of muscles
tubercle
a small rounded projection or protuberance, especially on a bone or on the surface of an animal or plant.
tuberosity
an elevation on the proximal, anterior aspect of the tibia
vertebra
individual segment of the spine composed of the vertebral body, vertebral arch, spinous process, transverse process, and lamina, enclosing the neural canal and spinal cord

decreasing the angle of the ankle joint so that the foot moves upward
extension
increasing the angle between two bones
flexion
decreasing the angle between two bones
plantar flexion
motion that moves the foot downward toward the ground as when pointing the toes or stepping on the gas pedal
