JOINTS Flashcards
Joints/articulations
Place where 2 or more bones join together.
Fibrous joints
These joints are inflexible layers of dense, connective tissue and hold bones tightly together. Such as in the joints of the skull called sutures.
Cartilaginous joints
These joints allow only slight movement and connects bones with cartilages. message, Examples include the site where ribs connect to the sternum and the pubic symphysis.
Synovial joints
These joints are where two bones connect to allow a wide range of motion. These joints contain a synovial capsule, a synovial membrane lining the capsule, and synovial fluid that keeps the joint lubricated.
Ligaments
Connect one phone to another bone or join bone to cartilage. A bursa is a fibrous sack that acts as a cushion to Eason movement in areas where there is a lot of friction.
Axial skeletal system
The axial, skeletal system is composed of the bones of the skull and spinal column, as well as the hyoid bone in the throat. The bones in the middle ear and the bones of the rib cage. There are 80 bones in the axial skeletal system.
Appendicular skeleton system
The appendicular skeleton system refers to the 126 bones of the upper and lower appendages.
The spinal column
The spinal column protects the spinal nerves of the nervous system. It is made by complex bone structures, called vertebrae.
Cervical vertebrae
C1-C7 the first seven vertebrae protect the cervical spinal nerves of the neck.
Thoracic vertebrae
T1-T12 the next 12 vertebrae protect the spinal nerves of the thorax.
Lumbar vertebrae
L1-L5 the next five vertebrae project, the spinal nerves of the lumbar region.
The sacrum
The sacrum is the slightly curved, triangular, bony structure of the lower back. It is formed by five vertebrae fused together.
The coccyx
The coccyx called the tailbone. It is formed by 3 to 5 vertebrae fused together.
