Week 2- Chapter 7 Flashcards
Abduction
Movement away from midline or axis of the body, opposite of adduction
Acetabulum
Area where the three bones of the hip unite to form a deep socket into which the head of the femur fits to form the hip joint
Amphiarthroses
Partially movable joint (Ex: symphysis pubis)
Adduction
Movement or part of the body or a limb toward the midline of body, opposite of abduction
Articular cartilage
Thin layer of cartilage over the ends of long bones
Appendicular skeleton
Part of skeleton consisting of pectoral and pelvic girdles and limbs
Arthritis
Inflammation of a joint
Atlas
First cervical vertebra, articulates with the axis and occipital skull bone
Axial skeleton
Skeleton of head and trunk
Axis
Second cervical vertebra, forms a pivot for the atlas
Bursae
Closed sacs with a synovial membrane lining, found in the spaces of connective tissue between muscles, tendons, ligaments, and bones
Bone marrow
Fat storage center in the medullary cavity
Bone cancer
Bone cancer
Ball and socket joint
Joint that connects a ball shaped bone with a concave bone that allows the greatest freedom of movement
Bursitis
Inflammation of a bursa
Calcaneus
Heel bone
Cancellous bone
See spongey bone
Carpals
Bones of the wrist
Circumduction
Circular movement of joint
Cervical vertebrae
First seven bones of the spinal column
Clavicles
Collarbone
Closed/simple fracture
A fractured in which the bone is broken, but the broken ends do not pierce through the skin to form an external wound
Compact bone
Also known as hard bone, strong and light
Condyloid joints
Joint that allows for two degrees of movement
Diaphysis
Shaft of a long bone
Coccyx
Tailbone
Comminuted fracture
A fracture that occurs when the bone is splintered or broken into many pieces that can become embedded into the surrounding tissue
Diarthroses
Movable joint (ex: knee, elbow)
Ethmoid
Bone of the cranium located between the eyes
Dislocation
Displacement of one or more bones of a joint or organ from the original position
Epiphysis
The end of a long bone
Extension
Act of increasing the angle between two bones
Endosteum
Lining of the medullary cavity in the long bone
Femur
Longest and strongest bone in the body, thigh bone
Fibula
Slender bone at outer edge of the lower leg
Flatfeet
Weakening of the leg muscles that support the arch of the foot, also called talipes
Flexion
The act of bending a limb or decreasing the angle between two bones
Fontanel
Unossified areas in the infant skull, soft spot
Gout
Increase in uric acid crystals in the bloodstream, which are deposited in joint cavities, especially the great toe
Frontal
Bone of the skull that forms the forehead
Fracture
A break in a bone
Gliding joints
Joint in which the nearly flat surfaces of the bones glide across each other (ex: vertebrae)
Greenstick fracture
Simplest form of fracture where the bones are partly bent, but it never completely separates
Hairline fracture
A tiny crack in the bone that typically occurs from overuse
