Bring on the Bones
These cells regulate the metabolism of bones.
What are osteocytes?
The site where two or more bones meet to determine range of motion.
What is a joint articulation?
This structure attaches muscle to bone.
What is a tendon?
This is a disruption in the integrity of a living bone involving injury to bone marrow, periosteum, and adjacent soft tissues
What is a fracture?
A patient has a fracture of the hand and has developed inappropriate pain, burning, muscle weakness, pain with passive stretching of the involved muscles and pain with active flexion of the muscles.
What is compartment syndrome?
These cells form new bones.
What are osteoblasts?
What is the synarthrotic joint?
This type of skeletal muscle is a result of the organization of muscle fibers into contractile units called sarcomeres.
What is striated muscle?
A type of fracture line that runs across the bone at an angle of 45 to 60 degrees.
What is an oblique fracture?
A patient had a traumatic fracture with open wounds and several days later developed pain and a heavy sensation in the affected area, followed by localized edema and exudation of a thin dark fluid from the wound with a musty odor.
What is gas gangrene?
Major cells that take bone away that are critical in remodeling of bone and tumors.
What are osteoclasts?
This is the most movable joint, containing a fibrous joint capsule and fluid which fills the joint cavity that lubricates the joint surface.
What is the synovial joint?
The anterior horn cell, its axon, and its muscle fiber comprise this structure.
What is the motor unit?
This fracture is associated with either neurovascular, visceral, ligamentous, or muscular damage.
What is a complicated fracture?
This is caused by reduced bone mass/density and an imbalance of bone resorption and formation.
What is osteoporosis?
This part of the bone is separated from the metaphysis by a cartilaginous growth plate and after puberty if calcifies and merges with the metaphysis.
What is the epiphyseal plate?
This is a freely movable joint found in the knee, hip, ankle, fingers, toes.
What is a diarthrotic joint?
These are the functional subunits of muscle contraction.
What are myofibrils?
This occurs what a bone fracture heals in a nonanatomic position.
What is malunion?
An elderly patient is complaining of joint pain related to use, pain getting worse during the day, morning stiffness (< 20 minutes) and pain after inactivity, with a decreased range of motion, joint instability, bony enlargement and restricted movement.
What is osteoarthritis?
This consists of spongy bone covered by a thin layer of compact bone.
What is a cuboidal bone?
this is a slightly movable joint connected by ligaments/cartilage found in the vertebrae.
What is an amphiarthrotic joint?
This is the site where muscle contraction is initiated which contains actin and myosin and is responsible for converting chemical energy into movement.
What is the sarcomere?
This is the final stage of the five stages of bone healing.
What is remodeling?
A patient presents with morning joint stiffness lasting at least 1 hour that has been present for at least 6 weeks and arthritis of the hands, wrist elbow and ankles for at least 6 weeks with soft tissue swelling and fatigue.
What is rheumatoid arthritis?
