the bony joints. Chapter 8 part 2

STUDY
PLAY
the bony joint is the fusion of two bones called
synostosis
because the connectione between 2 bones present in a synostis is immovable it is considered
synarthrotic joint
the connection between bone of diaphysis and epiphysis after bone lengthening stops is an example of
synostosis
what suture exists between two frontal bones that fuse into one bone during infancy is an example of synostosis
metopic
what joints are complex structures that allow significant amounts of movement
synovial
the synovial joint is surrounded by what
fibrous capsule
at ends of articulating bones are within a joint cavity that contains
synovial fluid which bathes the tissues of cavity.
the fluid is produced by synovial membrane that is made of
areolar tissue which lines the inner surface of joint cavity
what is a characteristic of articular cartilage
smooth slick does not have perichondrium, coated with synovial fluid that lubricates and minimizes frictions between articulating surfaces
what surrounds articular cartilage
synovial fluid
to remain healthy articular cartilage which is
non vascular, relies on circulation of synovial fluid for movement of nutrients to chondrocytes within cartilage and removal of wastes from them.
what acts as a shock absorber by helping to evenly distribute pressure within articular cavity and across articulating surface as joint is used
synovial fluid
what is a pad made of fibrocartilage which is positioned between opening of bones of synovial joint
meniscus
localized masses of adipose tissue that fill spaces and act as packing material within synovial joint cavity
fat pads
strong cords of dense connective tissue that stabilize and limit movement of joint
ligaments
small synovial membrane lined pockets in connective tissue around synovial membrane.
bursae
what doe bursae contain
synovial fluid - their presence helps reduce friction where ligaments rub against other tissues
what is the condition of having an inflamed and painful busa
bursitis
how are synovial joints stabilized?
by joint capsule and ligaments, shape of articulating surface, skeletal muscle, and tendons
