musculoskeletal system Flashcards
1
Q
the spinal column
A
- a series of small bones forming a flexible & supportive structure down the back
- discs of cartilage found between the vertebrae to cushion them during locomotion
2
Q
cartilage
A
firm, flexable connective tissue
3
Q
what do bones include
A
- compact bone tissue
- spongey bone
- marrow cavity
4
Q
what is a joint
A
a structure in the body at which 2 parts of the skeleton are fitted together. this allows us to move
5
Q
fiberous joint + e.g.
A
bones held together without cartilage e.g. skull
6
Q
what are the 3 types of joints
A
- fiberous
- cartilaginous
- synovial
7
Q
cartilaginous joint e.g.
A
e.g. intervertebral disks holding vertebrae together
8
Q
features of a synovial joint
A
- fibrous capsule
- synovial fluid
- synovial membrane
- articular cartilage
9
Q
synovial joint + e.g.
A
- allows movement in one direction only
- hinge joint (elboe + knee)
10
Q
cartilage
A
reduces friction- acts as a shock absorber
11
Q
synovial fluid
A
lubricates the joint
12
Q
synovial membrane
A
produces synovial fluid
13
Q
tendon
A
joins a muscle to a bone enabeling movement- NON ELASTIC
14
Q
ligament
A
joins bone to bone, stabelising the joint- ELASTIC
15
Q
what is the musculosketal system made up of
A
- bones of the skeleton
- muscles
- cartilage
- tendons
- ligaments
- joints connective tissue
