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)
