joint
A place in the body where two bones come together
squamous suture
Between parietal and temporal bones
Joints that unite bones with cartilage are called:
Cartilaginous joints
Ribs 8 to 12 are called ________ because they do not attach directly to the sternum.
False Ribs
the four major cranial sutures are:
Lambdoid suture Coronal suture Sagittal suture Squamous sutures
There are 6 types of synovial joints
Pivot, Gliding, Hinge, Saddle, Condyloid, ball and socket
coronal suture
between frontal and parietal bones
lambdoid suture
between parietal bones and occipital bone
sagittal suture
between the two parietal bones
wormian bones
bones that form within the structures of skull
vertebrae is an example of what type of joint?
cartilaginous joint
the vertebral column is grouped into 5 regions:
cervical spine (C1-C7) thoracic spine (T1-T12) lumbar spine (L1-L5) sacral spine coccygeal spine
Bone structure
compact bone and spongy bone
thoracic cage
formed by ribs and sternum, protects internal organs and gives attachment to muscles involved in respiration and upper limb movement
synovial joints
freely movable joints
The Knee are an example of a ___________ joint
full movement synovial capsule hinge joint
Skull sutures are an example of which type of joint?
immovable fibrous joints
short bones
length nearly equal to width
long bones
longer than they are wide
Sternum
manubrium, body of sternum, xiphoid process
fibrous joints
most of these have thick connective tissue between them which is why most are immovable
cranial bones
occipital, parietal, frontal, temporal, sphenoid, ethmoid
sesamoid bones
small rounded bones that form within tendons in response to stress
there are three types of fibrous joints:
sutures, syndesmoses, gomphoses
there are two types of cartilaginous joints:
synchondrosis, symphysis
Ribs 1-7
true ribs (bc they attach directly to sternum)
