joints and structures Flashcards
what are joints
where two (or more) bones (or cartilage and bone) meet
what are the functions of joints
movement and flexibility
stability/attachment between bones
what are types of connective tissues
- skeletal muscle
- fibrous tissue
- tendon
- ligament
- cartilage
what is cartilage
firmer than other types of conective tissues
3 functions:
- provide support / strength
- smooth, reduced friction surface at joints
- involved in development/growth of bones
hyaline cartilage?
very smooth and blue/white in appearance
fibrocartilage?
very tough/ slightly flexible connective tissue
elastic fibrocartilage?
flexible tissue providing shape/support
what are solid joints?
bones connected by either dense fibrous CT or cartilage
function mainly for support/strength
movement much more restrcited that synovial joints
what are fibrous joints
allow virtually no movement
bones joined by strong fibrous tissue
3 types = sutures, gomphoses, syndesmoses
sutures?
only occur in the skull - become more fixed and immoveable
gomphoses?
occur between the teeth and mandible bone - very minimal movement overtime
syndesmoses?
variable but minimal movement - distal tib/fib distal radius/ulna
cartilaginous joints?
virtually no/minimal movement, permanent joints all in midline
synchondroses?
connected by hyaline cartilage, no/very minimal movement
symphyses?
variable movement
