anatomy of bones and joints Flashcards
What is the standard forward facing position called?
Anatomical position.
What is the medial plane?
A sagittal plane that cuts straight down the middle.
Name all the different spatial descriptors.
Top = superior, Bottom = inferior, Back = posterior, Front = Anterior.
Limbs close to attachment to trunk = Proximal
Far away from attachment point = distal.
What side does cross - sectional imaging always show.
Inferior.
What is a joint?
A union between two or more rigid components (bone or cartilage).
Why do we need joints?
Bones are very rigid, so require joints for movement. Also require them for growth.
Name the three types of joints.
Fibrous, cartilaginous, and synovial.
What type of joint is made of dense fibrous connective tissue?
Fibrous joint.
Fibrous joints have little movement in adults but more in children. Why is this beneficial?
Fibrous joints are found in sutures in the brain. The movement of these joints in children is beneficial for the children for flexibility as they are born.
What kind of joints are found in teeth and between two leg bones.
Fibrous joints.
What are the names of the primary and secondary cartilaginous joints?
Synchondroses - primary - one types of cartilage
Symphyses - secondary - two types of cartilage
What type of cartilaginous bone ossifies.
Synchondroses.
What type of cartilaginous bone allows bone growth and has no movement.
Synchondroses.
Where is symphyses found?
Midline, pubic bone and spine.
Which type of joint has the greatest movement?
Synovial joints.
