Chapter 3: Bones, Joints and Muscles Flashcards
Bone tissue
Osseous tissue
Process of bone formation
Ossification
Bone cell that forms bone tissue
Osteoblast

Calcium
Spongy or porous bone found at the ends of long bones and in the inner portions of long bones
Cancellous bone
Structural protein making up the white fibrous strands found in bone
Collagen
Hard, dense bone tissue that forms the outer layer of bone
Compact bone
Shaft of a long bone
Diaphysis
Inner lining of bone
Endosteum
Cartilaginous region of long bones where lengthwise growth takes place
Epiphyseal plate
Each end of a long bone
Epiphysis
Central, hollowed-out portion in the shaft of a long bone that contains yellow bone marrow
Medullary cavity
Flared portion of a long bone between epiphyseal plate and diaphysis
Metaphysis
Membrane surrounding bone
Periosteum
Found in cancellous bone and site of hematopoeisis
Red bone marrow
Found in the diaphysis of bone and consists of fatty tissue
Yellow bone marrow
Examples of these bones are: femur, tibia, radius, metacarpals
Long bones
Examples of these bones include the carpals and tarsals
Short bones
Examples of these bones are: scapula, ribs and bones of pelvis and skull
Flat bones
Small bones embedded in tendons
Sesamoid bones
Vertebrae are what type of bone?
Irregular bones
Bone found in the penis of some carnivores
Os penis
Bone found in the nose of pigs
Os rostri
Bone found in the heart of ruminants
Os cordis
Hereditary condition in which the bones and cartilage of limbs fail to grow to normal size
Achondroplasia
Removal of limb or other appendage
Amputation
Deposit of calcium salts in tissue
Calcification
Bone deposit formed at the ends of a bone fracture; absorbed as fracture is repaired and replaced by true bone
Callus
Procedure to dissolve a protion of the center of an intervertebral disc (IVD) to treat a herniated IVD
Chemonucleolysis
Crackling sounds produced by the grating of broken bones
Crepitation
Loss of calcium salts in bones and teeth
Decalcification
Displacement of a bone from its joint
Dislocation
Sudden breaking of bone
Fracture
Abnormal protrusion of an IVD into the neural cavity or spinal nerves
Herniation of IVD
Act of preventing a bone from being moved
Immobilization
Abnormal, increased, dorsal curvature of the spine
Kyphosis
“Hunchback”
Removal of part of the vertebral arch to relieve pressure from a ruptured IVD
Laminectomy
Downward or ventral curvature of the lumbar spine
Lordosis
“Swayback”
Branch of surgery dealing with the skeletal system
Orthopedic
Decreased bone density due to loss of bone tissue
Osteoporosis
Correction of a fracture
Reduction
Piece of dead bone tissue that has separated from healthy bone tissue during necrosis (cell death)
Sequestrum
Joint between atlas and axis “No joint”
Atlanto-axial joint
Joint between atlas and occipital “Yes joint”
Atlanto-occipital joint
Joint consisting of carpal bones
Carpus
“Wrist”
Joint between pelvis and the femur
Coxofemoral joint
“Hip”
Joint between femur and the tibia (stifle joint)
Femorotibial joint
“Stifle”
Joint where the humerus meets the radius and ulna
Humeroradioulnar joint
“Elbow”
Joint between the sacrum and ilium
Sacroiliac joint
Joint between the scapula and humerus
Scapulohumeral joint
“Shoulder”
Joint consisting of tarsal bones
Tarsus
“Hock”
Where two or more bones come together
Articulation
Sac of fluid near a joint that acts as a lubrication to ease friction between tissues
Bursa
Connective tissue that binds bone to bone
Ligament
Space between bones at a synovial joint which contains synovial fluid
Synovial cavity
Viscous fluid within the synovial cavity that acts as a lubricant between bones
Synovial joint
Membrane lining the synovial cavity that produces synovial fluid
Synovial membrane
Connective tissue that binds muscle to bone
Tendon
Movement AWAY from midline of the body
Abduction
Movement TOWARD the midline of the body
Adduction
Backward bending (flexion)
Dorsiflexion
Increasing angle between two bones at a joint
Extension
Decreasing angle between two bones at a joint
Flexion
The act of turning the palmar or plantar surface downward
Pronation
The act of turning the palmar or plantar surface upward
Supination
Circular movement that turns a body part around a central point
Rotation
Fibrous band that connects two surfaces that are normally separate
Adhesion
Able to walk
Ambulatory
No development due to decrease from normal cell size
Atrophy
Increased development due to an increase in cell numbers
Hyperplasia
Excessive development due to increase in cell size
Hypertrophy
Incomplete development due to an increase in cell numbers
Hypoplasia
Looseness
Laxity
Muscle weakness
Myasthenia
Syndrome of muscular weakness that is aggravated by activity and relieved by rest
Myasthesnia gravis
Repetitive contractions of skeletal muscles that persist during sleep
Myoclonus
Disorder in which there is a delayed relaxation of a muscle after contraction
Myotonia
Inflammation of the tendon and tendon sheath
Tenosynovitis
Continuous muscle spasms or twitching
Tetany
Muscle tone; balanced muscle tension
Tonus
