Anatomy Flashcards
What does the CNS consist of?
Brain and spinal cord
What does the ANS consist of?
Everything except the brain and spinal cord
What is cartillage?
Less rigid than bone
3 types of joints?
Fibrous
Cartilagenous
Synovial
2 types of fibrous joints
Sutures
Fibrous sheets
Where are sutures found?
Between skull bones
Example of fibrous joint
Interosseous membrane (between radius & ulna)
2 types of cartilaginous joints
Primary
Secondary
Which kind of joints can “slip”?
Cartilaginous
slipped disc, slipped femoral epiphysic
Example of primary cartilaginous joints
`Epiphyseal growth plate (ossifies after gorwth is complete)
Example of secondary cartilagenous joint
iNTERVERTEBRAL DISCS
What are fontanelles?
Wide sutures in the neonatal skull
What is ‘moulding’?
The overlap of the frontal, parietal, temporal and occipital bones when a baby is being squeezed through the birth canal
2 layers of intervertebral discs
Anulus Fibrosus
Nucleus pulposus
What covers the articulating surfaces in synovial joints?
Hyaline cartillage
What are the 2 layers of the capsule hat wraps around syovial joints?
a superficial strong fibrous layer
a deeper synovial membrane layer to secrete synovial fluid
What is the joint cavity?
The space witin the joint capsule
What supports synovial joints?
Ligament (connect bone to boone)
What are tendons?
Fibrous bands that connect skeletal muscle to bone
What is the purpose of bursae?
Stop friction
What are the 2 types of bursae in synovial joint?
synovial fluid-filled extensions of the joint capsule
Closed sacs of synovial membrane containing synovial fluid near to but separate from the joint cavity
5 types of synovial joint
Pivot Plane Hinge Biaxial Ball & socket
Example of pivot joint
superior park of neck (saking head)
Example of plane joint?
acromioclavicular joint (minimal movement in one plane)
