Anatomy Quiz #2 2/5/2014 Flashcards
Tough white bands of tissue that bind bones together
Ligaments
Specialized tough cords or bands of dense white connective tissue that are continuous with the periosteum. They also attache muscle to bone
Tendons
Plates of shiny connective tissue that are lubricated by synovial fluid to provide a slippery surface over which bones may move freely
Cartilage
The major site of bone elongation, located just proximal to the bone ends. Also called the growth plate
Physis or epiphyseal plate
The end of a long bone
Epiphyses
The area of long bone where the diaphysis and epiphysis converge. The epiphyseal plate is located here
Metaphysis
Large, multinucleated cells that dissolve bone tissue and play a major role in bone remodeling
Osteoclasts
A bone-forming cell
Osteoblast
An incomplete fracture in which the bone is bent and only the otter arc of the bend is broken. This fracture primarily occurs in children and often heals quickly
Greenstick fracture
A fracture straight across the shaft of a bone
Transverse fracture
A fracture at an angle to the shaft of a bone
Oblique fracture
A fracture that twists around the shaft of a bone
Spiral fracture
A fracture in which the bone end is fragmented
Comminuted fracture
A fracture in which one fragmented bone end is wedged into the other fragmented end
Impacted fracture
A fracture in which the bone collapses
Compression fracture
The topmost layer of bone on one side of the bone is compressed, causing the other side to bend away from the growth plate. Also known as a buckle fracture. Mostly found in children
Torus fracture
The point of the skull where the parietal bones join together
Sagittal suture (back of the head)
The point where parietal bones join together with the frontal bone
Coronal suture
The three small bones in the middle ear: the malleus, Incus, and Stapes
Ossicles
The large opening at the bottom of the skull through which the brain connects with the spinal cord
Foramen magnum
A prominent bony ridge in the center of the anterior fossa to which the meninges are attached
Crustal galli
The three layers of membrane, the dura, arachnoid, and pia, that surround the brain
Meninges
A fracture of the floor of the orbit usually caused by a blow to the eye
Blowout fracture
Soft tissue within the tooth
